The Ability To Test Welds Has Progressed Rapidly Over The
The ability to test welds has progressed rapidly over the years. After the discovery of the short
pulsed electric arc in 1800 by Humphry Davy[3][4] and the continuous electric arc by Vasily Petrov
in 1802, there was little development in electrical welding until 1881.Around that time there was
little to be done as far as the rigidity of inspection goes. As long as man has been on earth, we have
been visually testing things to see if it passes our persona critique of standard perfection. With weld
quality assurance Visual Testing (VT) is where it welding inspection all starts. Before the first
welding arc is struck, materials should be examined to see if they meet specifications for quality,
type, size, cleanliness and freedom from defects. ... Show more content on Helpwriting.net ...
Floyd Firestone. With the general principle of my device consists of sending high frequency
vibrations into the part to be inspected, ultrasonic testing is applied to many fields of metallurgy
withing many occupations. Ultrasonic testing becomes less suitable when determining porosity in
welds, because round gas pores respond as a series of single point reflectors to ultrasonic tests. UT
inspection system consists of several functional units, such as the pulser/receiver, transducer, and
display device. How Ultrasonic Testing (UT) works is by having an ultrasound transducer connected
to a diagnostic machine is passed over the object being inspected.The pulser/receiver is an electronic
device that produces high voltage electrical pulses, while the transducer, which is driven by the
pulser generates high frequency ultrasonic energy. Separated by test object is a couplant. As sound is
introduced, it spreads through the materials in the form of sound waves. When there is a
discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the
flaw surface. With a few advantages ranging from: High penetrating power, which allows the
detection of flaws deep in the part, great accuracy, non–hazardous operation, portability, and
immediate results. A few advantages of UT are :
It is sensitive to both surface and subsurface discontinuities.

Welders Essay
Welders are a large part of the construction industry. Welders build frames for large buildings and
things like bridges. Welders build support frames for many things. They put together car frames and
piece together pipes for gas lines and oil field work. Welders could be called pipefitters,
boilermakers, and ironworkers. Welders must have 500 hours a labor put in before a holiday to get a
paid holiday. Paid holidays include Memorial Day, labor day, 4th of July, thanksgiving, Christmas
day, and new year's day. Welders don't have many off days. Your employer needs you to show up to
work. If you don't show up to work you cost the company you work for time and money. Welders

The three main types of welding are tig, mig, and stick welding. There is also underwater welding
which isn't as common because its much more dangerous. Mig welding is when a wire electrode is
used to join 2 pieces of metal together. Mig stands for metal inert gas. Mig welding can be used for
thin or thick metals. Shielded metal arc welding (stick welding) is a solid metal electrode that is
covered in a flux coating. Stick welding isn't as sensitive to wind as mig welding is. Which means
you can weld outside or in places that have a draft easier than with a mig welder. Stick welding is
usually used to weld iron and steel but nickel and aluminum can also be welded this way. Tig
welding, tungsten inert gas welding. Has a non–consumable tungsten electrode that directs the
electric current. The welder is usually ran with gas like argon or helium to help clean the metal
being welded. You use a filler metal to melt the two metals together. Tig welding can be used for all
kinds of

Best Welding Helmet
When it comes to welding, whether doing MIG, TIG, or Stick welding, you need the best

The Components Of Welding Process
Today, many fabrication industry using a various types of welding process in which arc welding
process is very common and widely used welding process. As we are fabricated or manufactured a
product with the help of the arc welding, there is a some problem occur during the process and as a
result, different types of defects are occurred in the products which reduce the reliability of the
products and also reduce the strength of the product or products parts. So it is necessary to avoid the
defects from the product and improve the overall quality of the products. Our projects also provides
solutions to arc welding defect and advises towards prevention of arc welding defect to improve
overall product quality, reduce costs, and enhance customer satisfaction.

Clean Technology For Air Pollution Reduction And...
Abstract – Cleaner Production (CP) strategies are fundamentally concerned with operations,
environmental sustainability and maximization of waste reduction, recycling, and reuse. This
research has the purpose to identify the use of resources and sources of pollution in a cleaning
equipments manufacturing and testing factory in order to apply the principles of clean technology
for air pollution reduction and standardization of waste water. The research focuses on the
assessment implemented by Clean Technology (CT) to inquire into the cause of air pollution and
wastewater. The main application of clean technology is to minimize air pollution in the welding
area (production area), and to develop a better system for wastewater treatment. Installation of local
exhaust ventilation with a proper design can prevent the emission of welding fumes to the
atmosphere and implementation of a treatment plant will help for the reuse of water. Both can give
the company a better environment friendly and working atmosphere. A case study is carried out in a
cleaning equipment manufacturing company.

Abstract
In the present work AISI 316L stainless steel samples have been welded by MIG welding. Butt
joints have been made. Plate thickness is kept constant (= 3mm). Some important parameters have
been varied during welding. Thus several butt–welded joints have been made. Each sample of the
joints has been prepared under certain combination of welding parameters. The parameters
considered for variation, in the present work have been welding current, gas flow rate and nozzle to
plate distance. The design of experiment has been done using L9 Taguchi design of experiment. The
influence of the process parameters (mainly current, gas flow rate and nozzle to plate distance) has
been examined visually and also through X–ray radiographic tests. Next, samples have been cut,
machined to conform to some specified dimensions for tensile testing. The quality of the weld has
been evaluated in terms of ultimate strength, yield strength and percentage of elongation of the

was first documented as metal shaping in Egypt in 4000 B.C. Some civilizations started with less
magnetic materials like copper, then progressed to more iron based materials like bronze, gold, iron
and silver. In 3000 B.C. using pressure welding The Sumerians beat and formed swords for battle.

the next thing you need is to use the right technique. with the right use of the right technique you
can reduce most all the distortion in the weld. distortion is the under cut, porosity the wrong doing
of the bead. if you have distortion you have a weld that is no good. the z weave technique is where
you move the rod side to side and pause 2 seconds at the corners of the weld. there is also the
stringer bead where you move in small tight circles in the direction of your weld. both techniques
are good it all depends on the welder those are the two biggest techniques used on the pipeline. after
you learn all this your training will be sufficient the next thing you need to do is go get your
certifications.

Mig Welding
What is MIG Welding?
Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding (GMAW) is a
process that was developed in the 1940s for welding aluminum and other non–ferrous metals. MIG
welding is an automatic or semi–automatic process in which a wire connected to a source of direct
current acts as an electrode to join two pieces of metal as it is continuously passed through a
welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the
same time as the wire electrode. This inert gas acts as a shield, keeping airborne contaminants away
from the weld zone.
Advantages and Disadvantages of MIG Welding
The primary advantage of MIG welding is that it allows metal to be welded much more ... Show
more content on Helpwriting.net ...
 The necessity for the inert gas shield means that MIG welding cannot be used in an open area
where the wind would blow away the gas shield.
Since its development in the middle of the 20th century, MIG welding has become commonplace in
many manufacturing operations. For example, it is commonly used in the automobile industry
because of its ability to produce clean welds, and the fact that it welds metals quickly.
What is TIG Welding?
Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as
magnesium and aluminum. The TIG welding method became popular and useful in the early 1940s
and, as a result, has greatly propelled the use of aluminum for welding and structural processes. TIG
welding is commonly used for both high quality and manual welding.
During the process of TIG welding, an arc is formed between a pointed tungsten electrode and the
area to be welded. As a result of the gas shield, a clean weld is formed. This prevents oxidization
from occurring.
The type of gas shielding typically used for TIG welding is argon, helium, or a combination of both.
When combined, these two gases can ensure a higher welding speed and welding penetration. Argon
is the preference of most welders when it comes to TIG welding. It is often used simply because it is
heavier than air and provides better coverage when welding.
With TIG welding, one can perform a variety of

In most welding you will need to know how to study blueprints, sketches, or specification
calculates. Welding is the best way of permanently joining metal parts because welding is used in
building ships, buildings, and cars. Welding is good for repair because the welds will not come apart
unless you cut it with a torch. Welding also is used to join steel beams in the construction of
buildings, bridges, and other structures and to join pipes in pipelines. The work that welders do and
the equipment they use all come from the company they work with. Arc welding is the most
common type of welding today because arc welding takes time and the welds can go there just about
anything and it want come apart. The type of weld normally is determined by the types of / being
joined and the conditions under which the welding is to take place. Welders are often exposed to a
number of hazards, including very hot materials and the intense light created by the arc if you stare
at the light without the proper eye protection it can cause you to go blind. They wear safety shoes,

Taking a Look at Welding
Welding is manufacturing process of joining between pieces of materials and its applications can be
seen in every industry field. Dissimilar metal welding is considered as a procedure of making joints
between different metals having different chemical compositions, mechanical and metallurgical
properties. This procedure is needed in the cases where a section of an industrial component has to
operate under a different service condition or in cases where a component is removed and is
replaced by another component with different composition.in industry use of dissimilar metal
welding can be seen in the superheater section of powered boilers and pipe runs between ferritic low
alloy steels and austenitic steels. Another common case which transition welds occur is in nuclear
power plants, when there is a need to join the inlet and outlet nozzles of pressure vessels (low alloy
steels) to pipes which are made of low alloy steels by using Nickel alloys filler metal. In order to
make a joint between different metals most solid state welding procedures can be applied, such as
diffusion welding, explosion welding, friction welding, or ultra–sonic welding .the most three
common diffusion processes which are used in making transition welds are shielded metal arc
welding (SMAW), gas metal arc welding (GMAW), and gas tungsten arc welding (GTAW).
In order to make a joint between dissimilar metals different factors should be considered to ensure
that the properties are optimised across the

the use of heat and pressure. The welder I am using is a Miller 350p MIG. This welder has three
processes it can do: MIG welding, pulsed MIG and flux–cored MIG welding. MIG welding works
by forming one droplet of molten metal at the end of the electrode poss the arc and into the puddle.
Pulsed MIG welding is a non–contact transfer method between the electrode and the weld puddle.
This means that the electrode never touches the puddle. This is accomplished through high–speed
manipulation of the electrical output of the welding machine. It is designed to be a spatterless
process. It runs at a lower heat input than a spray or globular transfer method.er pulse. Then, the
right amount of current is added to push that one droplet acr A weld is only as strong as your

Hydrogen : What Is Hydrogen Cracking?
Hydrogen Cracking
What is hydrogen cracking? It is probably the most talked about failure mechanism associated with
the welding industry. It is also known as hydrogen induced cracking, (HIC); hydrogen assisted
cracking, (HAC); cold cracking,(CC); delayed cracking, (DC); under–bead cracking, (UBC); and
hydrogen embrittlement, (HE).
HISTORY
Hydrogen cracking of welds first became a major concern during the first part of the 20th century.
Up until that time welding was experimented with, but not used in normal production. A few
transmission pipelines were built using gas welding and arc welding was being used in shipbuilding
on a limited basis.
World War I and World War II pushed the envelope as far as manufacturing technology and made
welding a common manufacturing method. During a war it is very important to be able to
manufacture very quickly and efficiently. Welding helped a great deal to win the wars.
But as welding was taking place in large volumes in many different manufacturing and fabricating
industries, welding defects were also happening. Lack of penetration, lack of fusion, porosity, slag
inclusions and cracking were some of the more common defects. Cracking was especially
problematic because the cracks were sometimes visible on the surface of the weld and sometimes
they were either under the weld beads or delayed for several hours after the weld was complete. The
under bead and delayed cracking was especially dangerous because these cracks could

work somewhere else. 2 out of every 3 welders get jobs. Welders can not be fired without just cause.
Certain associations can and will hold on to certain welders if they qualify for as long as they can.
Jobs were concentrated in fabricated metal product manufacturing, transportation equipment
manufacturing, machinery manufacturing, architectural and structural metals, manufacturing and
construction. For example welders laid off in the auto industry have been able to find work in the
booming oil and gas industry, although the shift may require

Pipeline Welding Pipeline welding is a job that consists of welders joining industrial sized pipes to
each other in order for them to transport gasses, oil, and many other various substances across the
country. The pieces of pipe are joined by electrically fusing molten metal to make the two pieces
one. These pipes can stretch for thousands of miles and can be found all around the world. This job
may overlooked in today's time, but it is a very important feature that keeps this country running.
The first reason most people apply for this job is because they enjoy it at first. What is the point of

Welders generally have a year or less of training before they are out working in the field. Apart from
passing certification tests, there is very little required training needed to start working. This reason
alone appeals to many people simply because of the lack of a long term education and costly
schooling. Many state paid schools offer free or discounted costs for an education with some
programs such as the Tennessee Promise Program or the Free Application for Federal Student Aid
(or the FAFSA). These programs offer great chances for people who may not be able to afford
schooling an education to get the job they desire. These opportunities listed are there for anyone
who is willing to take the challenge.
Welding is a very good trade to know and can be very helpful in a wide variety of jobs. Although it
is not required in all workplaces or jobs, it could make one more of an asset to their employer. Many
jobs have machines, tools, and other necessary pieces of equipment that may break or need
something welded to them. Knowing to weld is a great tool and will put one far ahead of most
people. Many people know how to weld, but very few are good enough to be considered
professional. A person should always aspire to be the best in each field of work that they are
involved in.

INTRODUCTION
Welding is a process of fabrication used to join materials. Materials joined are usually metals of
thermoplastic materials. Effectiveness of process is gained by fusion, and in the same time that is
what differentiates welding from other techniques of metal joining, that do not melt the base
material.

Thermo–mechanically affected zone (TMAZ): In this region, the material has been plastically
deformed by the friction stir welding tool, and the heat from the process will also have exerted some
influence on the material. In the case of aluminium, it is possible to get significant plastic strain
without recrystallization in this region, and there is generally a distinct boundary between the
recrystallized zone and the deformed zones of the TMAZ. In the earlier classification, these two
sub–zones were treated as distinct microstructural regions. However, subsequent work on other
materials has shown that aluminium behaves in a different manner to most other materials, in that it
can be extensively deformed at high temperature without recrystallization. In other materials, the
distinct recrystallized region (the nugget) is absent, and the whole of the TMAZ appears to be
recrystallized. This is certainly true of materials which have no thermally induced phase
transformation which will in itself induce recrystallization without strain, for example pure titanium,
b titanium alloys, austenitic stainless steels and copper. In materials such as ferritic steels and a–b
titanium alloys (e.g.Ti–6Al–4V), understanding the microstructure is made more difficult by the

thermally induced phase transformation, and this can also make the HAZ/TMAZ boundary difficult
to identify

Pros And Cons Of Welding
Welding process Pros/Cons
The list of welding applications can be quite extensive. For the most part it can be broken down in
three main categories. Arc, Oxyfuel, Resistance, and Solid state welding. And the benefits of
automated welding can be in four main categories. Such benefits include, a decrease in scrap costs, a
decrease in labor costs, improvement on the quality of welds, and increased output of production.
Automated welding offers a more precise and clean weld and the welder given that it is a machine,
does not get tired or worn out and make human errors. With a company that purchases the welder,
over time the automated welder pays for itself and can run for hours on end producing the same
quality of weld and the same speed and pace that it is set for.

It is also the most common form of welding and easily learned. The equipment itself can be carried
into a confined space. The cost of shielding gas is also not required since the flux coating offers the
shielding requirements needed to sustain the arc. This process is also commonly used on most
metals and alloys.
Oxyfuel/Acetylene offers such benefits as not electrodes required for the welding process. It can be
done at all angle and used on thicker materials. The sub category abrasive water jet welding uses no
heat for the process.
Resistance Welding has a high production rate and set speed can be placed for production timing. It
can be easily automated for machines and for the most part it can be economical.
Solid State Welding uses extreme pressure to join two parenting metals together. The bond is free
from defects of the microstructure. It also uses no flux material, shielding gas or filler metals.
Although all forms of welding have their advantages, there are still disadvantages. Each one comes
with a certain downfall.

Energy is used talking about the electricity used to melt the metal or a flame used to heat it up or cut
it. Combustion could be used to talk about the flame that is used with Oxy–Acetylene welding,
cutting, or heating up metal. The metals all have different physical properties. An example would be
aluminum, it dissipated heat rapidly, so a different form of welding is required. Lead has a low
melting point so you can melt it with Oxy–Ace gases. They all have similar chemical properties.
They are very stable. It takes several hundred degrees to weld on. They all have different molar
masses. The molar masses of aluminum is 26.98 g/mol. The molar mass of iron is 55.84 g/mol. The
reactants of Oxy–Ace welding are oxygen, and acetylene, and a spark. The products would be a
flame that can be used for several different things. All the different things that are used in welding
have different protons, neutrons, and electrons. Oxygen has eight protons, neutrons, and electrons.

Their purpose is to detect the welding arc. Once the arc shows up, these sensors instantly darken.
The hue will go coming from #9 to #13, based on the arc. This particular complete course of action
occurs more rapidly than the blink of an eye.
Several companies promote the lens switching speed on the products. The faster the lens switching
speed is, the higher the quality of the protection is. Low–cost lens will often have 1/3,600 of a
second switching speed. The speed associated with top quality lens can go up to 1/16,000 of a
second. For anyone who is a professional welder, it really is suggested to purchase the auto–
darkening welding helmets with larger switching speed to avoid any kind of eye soreness.
On account of the simplicity and security of the auto–darkening welding helmets, just about every
welder can certainly considerably strengthen his/her overall performance. How, you may ask
yourself? First of all, you don't have to handle taking off the particular welding helmet and getting it
again on. This way, you can keep the gun/torch pointed to the actual place you want it to be.
Additionally, you will get rid of the neck soreness. You don't have to snap your head to lower the
helmet, or make any other movement. The auto–darkening welding helmet stays down, in a single

The Four Types Of Welding Career
Welding
Most of the dangers in welding are related to the wielder. Others are due to the environment that
they have to go to. In welding, most people can do most all things people would want to do. The
four main types of welding are Shielded Metal Arc Welding (The stick or SMAW), Metal Inert Gas
welding (Mig or GMAW), Oxyfuel Gas Welding (Oxyfuel or OFW) and Tungsten Inert Gas welding
(Tig). Welding is also a great career path because it pays well. The only drawback to it is that the
wielder will have to travel. In welding, there are three main careers they can go into. There are
structural, pipe, and Tig welding. Welding has a lot of big names. Lincoln and Miller are two of the
biggest welding companies in the world. Even though welding is a dangerous job, welding is a good
career because there are many different things people can do in a welding career and many types of
jobs in a welding career.
There are a lot of dangers in welding. Some of the dangers are ergonomic, electric shock, ultraviolet
light, toxic fumes and gases, heat, and noise. Ergonomic is a danger because the work environment
the wielder never knows where the wielder will be working. The work conditions can range from
really cold to really hot. In the workplace the wielder could be welding anywhere from the top of
skyscrapers to the bottom of the oceans. The ultraviolet light in welding is harmful because it is like
the radiation from the sun and it can damage the wielder's skin. The ultraviolet light is

The Physics Of Underwater Welding
Underwater welding has always fascinated me, especially when I heard about it during my time as a
welding student at Arizona Automotive Institute (AAI). The history behind it has always grasped my
attention for some time now. I always wanted to know more about underwater welding such as the
history, how it works, what it is used for, and the dangers that are associated with the job.
Konstantin Khrenov was a Soviet Engineer, who would later make history by inventing underwater
welding. Khrenov was born in 1894 in Borovsk, Russia. He got his education at Saint Petersburg
State Electrotechnical University (ETU), where he learned about electric welding, engineering, and
mathematics. He had also taught and did research at ETU until 1925.
Underwater welding was not a thing people attempted during the 20th century, because shooting an
electric arc into the water was considered suicide. Although, Khrenov had a desire to find a way to
weld underwater, but faced many challenges such as, trying to find the sporadic outflow of gas
bubbles which would cause major porosity or build up in the welds. During this time, he and others
did research and testing to create a waterproof coating for the electrodes for stable power. Once he
completed this, he tested out the electrodes.
After constant testing and practice he became successful at creating underwater welding in 1932.
Many people were enthused about the idea that two scientists wrote two articles about his
accomplishments. The Navy

Essay on The Process of Gas Metal Arc Welding
Gas metal arc welding, or most commonly referred to as MIG welding is a very common and
sometimes preferred method of welding. Gas metal arc is personally one of the easiest and
controllable welding types there is. Gas metal arc welding was originally made for weld materials
such as aluminum, copper, brass, tin and lead. It was also used on steels, but shielding gases were
highly expensive in the early 1900s limiting GMAW's use on steel. It wasn't till the mid 1900's for
GMAW to really take off. There were many different variations of arc–length, electrode size, and
power supply units. Since the MIG welder is so versatile, there are many different types of things to
make this piece of equipment.

Most power supplies also have a chart inside of them to set voltage and wire feed depending on
material thickness and electrode size.
Electrode and Shielding Gas Your electrode and both shielding gas can vary for different materials
and highly are affected by material thickness. The electrode is there to make contact to the wielding
surface and should have similar or same compositions as the metal being welded to. Your shielding
gas makes a big difference when welding to, especially with aluminum and other non–ferrous
metals. Shielding gases are used because most GMAW welding electrodes don't have a flux; the gas
is used to protect the weld. It is best to use pure inert gases such as helium and argon for non–
ferrous metals because of its cleaner and less oxidizing properties. Carbon dioxide is most
commonly used for steel or an inert and carbon dioxide gas mixture. The carbon dioxide supplies
deeper penetration needed for welding steel, but can sometimes cause an oxidation. Oxygen is even
a shielding gas but can cause your material to brittle and can cause porosity in your weld. Another
big part of GMAW and any welding operation is safety!
Safety
Safety when welding is very important and should be considered the most important thing to take in
consideration. You should always wear a very burn resistant glove; leather is commonly used by
most. Next is a wear non–tattered or protective clothing just in case some

On some accounts a welder can perform a task and not make a good weld. In an account with
Northrop Grumman Corp. and the U.S. Navy, some welders and inspectors were careless when it
came to performing routine job tasks and guidelines. In an article by the Newport News a welding
inspector falsified the passing of welds in a U.S. Navy shipyard. Robert Ruks admitted to falsifying
weld inspections on vessels in the shipyard. The Navy stated that, "the navy is considering re–
examining 23 welded joints on the submarine the USS New Hampshire", (Newport News, VA) 11
June 2009: Newspaper Source Plus. Wed. 14 Sept. 2015). Mistakes when welding can cause a bad
weld to occur. When running a bead you can go to slow which causes large beads of metal that make
the weld sloppy and blotchy, going too fast can cause small tiny beads of metal to not form a
constant bead. Those can lead to a weld that can fail its
