TYPES OF WELDING
Welding is a process that joins materials by heating them to melt or soften them and allowing them to cool, forming a permanent bond. It is commonly used in manufacturing to join metal parts like in automobiles, ships, and machinery. There are several types of welding including arc welding, gas welding, resistance welding, and solid state welding. Arc welding, one of the most common methods, uses an electric arc to heat and fuse metals while gas welding uses a flame from oxygen and fuel gases to do so. Welding has many applications and advantages but also limitations like safety hazards from high heat and difficulty detecting defects.
Welding processes-Brazing & Soldering
This document discusses different welding and joining processes. It begins by defining welding as a process that joins materials through heating and sometimes the use of filler material. It then discusses different types of welding processes, including plastic/pressure welding and fusion/non-pressure welding. The document further classifies welding into several categories such as arc, gas, resistance, thermit, solid state, and newer welding processes. It also discusses related processes like cutting and brazing. Finally, it provides details on brazing and soldering, defining them as lower temperature joining processes compared to welding and discussing their applications and advantages/disadvantages.
Cold welding
Cold welding is a solid-state welding process that uses pressure at room temperature to join metals through substantial deformation without melting. Both butt and lap joints can be formed. At least one metal must be ductile and heating is not applied. Surface preparation is important. The parts are cleaned, sheared, clamped in a die, and a forging force is applied to complete the weld. Advantages include no thermal effects on materials and a simple, fast, inexpensive process. Inspections can be difficult and some processes reduce part thickness. Common applications include wire drawing and sealing of heat-sensitive devices.
Soldering and brazing
Soldering and brazing are processes used to join metal pieces. Soldering uses a lower melting point filler metal to join parts, while brazing uses higher temperatures above 450°C for the filler metal to melt without melting the parts. Common soldering tools and techniques were discussed, along with advantages like low heat and joining dissimilar metals, and disadvantages like low joint strength. Brazing methods like torch, furnace, and induction brazing were also outlined, along with advantages like joining any metals but disadvantages of potentially weaker joints at high temperatures.
Cold pressure welding - read only
Cold pressure welding is a solid phase welding technique performed at room temperature using high compressive pressures. It relies on disrupting surface oxide layers through deformation from pressure, exposing clean metal surfaces that bond together via interatomic forces without melting. Historically, it has been used since 3000 BC for hammer welding but the earliest known example of ambient temperature welding dates to 700 BC in Britain for gold boxes. It is applicable to joining soft ductile metals like aluminum through butt or lap joints in circular wire sections or where heating is not possible. The mechanism involves metallic bonding between exposed atom clouds from each surface.

Fusion welding involves melting materials together using heat from sources like gas flames or electric arcs. It allows for joining of metal parts. Solid-state welding uses pressure, and sometimes heat, but no melting, to join metals. Welding is used in many industries like manufacturing, construction, and automotive as it allows for joining of metal parts that would otherwise be difficult or impossible to form as a single piece.
Brazing and morphology of brazed joint
Brazing is a metal joining process where two or more metals are joined together by melting a filler metal with a lower melting point than the adjoining metals and flowing it into the joint. There are different heat sources that can be used for brazing such as induction brazing, continuous brazing furnaces, batch furnaces, and vacuum brazing. Different braze filler metals are used depending on the base material and the desired maximum service temperature, including alloys for stainless steels, carbon steels, nickel alloys, and more. Brazing offers advantages over other joining techniques such as allowing batch processing, minimizing component distortion, and enabling the joining of dissimilar materials.

Explosion welding is a solid-state process that produces a high velocity interaction of dissimilar metals by a controlled detonation.
Metal Joining Process
There are two main categories of welding processes - fusion welding and solid state welding. Fusion welding involves melting the base metals using heat, sometimes with added filler metal. Common fusion processes are arc welding, resistance welding, and oxyfuel gas welding. Solid state welding joins metals without melting using pressure, heat, or both. Examples are forge welding and friction welding. The document then provides detailed descriptions and comparisons of various fusion welding techniques such as shielded metal arc welding, gas tungsten arc welding, plasma arc welding, and resistance spot welding.
Brazing and soldering
Soldering and brazing are metal joining processes where a filler metal is melted and drawn between closely fitted metal pieces through capillary action to form a permanent bond. Brazing differs from soldering in that the filler metal has a higher melting point above 450°C, while soldering uses filler metals with lower melting points. Common brazing methods include torch, furnace, dip, and induction brazing, while soldering is typically done with an iron or through wave soldering of printed circuit boards. Brazing and soldering offer advantages over welding like joining dissimilar metals, lower temperatures, less distortion and damage, and faster joining.
Ultrasonic welding
Ultrasonic welding uses high-frequency sound waves to melt and bond materials like plastics and thin metals together without needing bolts, solder, or adhesives. The sound waves generate heat through friction to join the materials in under 3 seconds. It allows for precise welding of very thin materials with minimal surface deformation or defects. However, it is best for thin materials and may not be economical for all applications.

INVESTIGATION OF RESIDUAL STRESSES IN WELDING AND ITS EFFECT ON MECHANICAL BE...Journal For Research
AISI310 is widely used in the manufacture of heat exchangers, radiant tubes, muffles, furnace parts, food processing equipments. Welding is widely used fabrication method in such type of industrial applications; but unfortunately welding induces few problems such as residual stresses and induced distortions. Residual stresses have significant effect on performance of the weld joint subjected to loading. The AISI310 is welded using matched filler material. Thus the weld joint consist of two different materials having different behavior under tensile loading. In this study residual stresses are estimated by using Labeas and Diamantakos formula and values are assigned as an initial stress in FEM of weld joint. The weldment specimen model is subjected to tensile loading and effect of residual stress on local yielding is investigated. The ANSYS is used for this purpose. The response of weld joint to monotonically increasing tensile load is determined experimentally by conducting the transverse and longitudinal tension tests on UTM. The stress-strain behavior of the weld joint is studied vis a vis virgin 310 stainless steel alloy.
Ultrasonic Welding
This document provides an outline and overview of ultrasonic welding. It describes the major components of an ultrasonic welding system, including the anvil, transducer, booster, and horn. It explains how ultrasonic welding works by using high-frequency vibrations and pressure to join materials without significant heat. Applications include welding plastics and metals with dissimilar melting points. Benefits are joining without consumables, less energy usage, and ability to weld materials like aluminum to copper. Limitations include being restricted primarily to nonferrous metals and plastics, and parts needing to be relatively light.
Ppt arc welding (grp 6)
Arc welding is a process that joins metals by heating them with an electric arc between an electrode and the metals, which allows for the metals to melt and bond together. It involves applying an electric current through an arc that is struck between the base metal and a consumable electrode or non-consumable electrode. The arc heats and eventually melts the base metal, and optionally filler metal is added from the electrode. The filler metal mixes with the base metal as it solidifies, creating a strong joint. Arc welding is commonly used due to its versatility, simplicity, and efficiency for welding metals like steel and aluminum. Personal protective equipment is required due to the heat, light, and fumes involved.
FSW Research Paper OURE Final Copy
This document summarizes Mitchell Smith's undergraduate research project on friction stir welding of similar and dissimilar metal alloys. Smith conducted trial welds of aluminum alloys to understand the friction stir welding process and machine settings. Welds were made of similar aluminum alloys and dissimilar aluminum-copper alloys. Challenges included preventing separation of metal pieces during welding. Further tests are needed to characterize the welds and properties of the welded metals, including microstructural analysis, tensile tests, and impact tests. Continued research on welding nano-reinforced metals could expand applications of friction stir welding in fields like nuclear engineering.
Welding-types, applications and invention.pdf
The term welding is actually used to join metal parts together by the use of
heat/pressure or both. It is an ancient technique that has also been used as a popular
occupation in the modern era.
Resistance welding
Resistance welding is a welding process that uses heat generated by resistance to electric current passing through the workpieces. There are several types of resistance welding including spot welding, seam welding, projection welding, flash welding, upset welding, percussion welding, and high frequency resistance welding. Spot welding is commonly used in automotive manufacturing to join vehicle body parts and involves applying pressure and electric current between two electrodes to weld metal sheets together.
ADVANCED WELDING PROCESS
The document discusses several advanced welding techniques: friction welding, explosive welding, laser beam welding, plasma arc welding, resistance welding, and thermite welding. Friction welding uses mechanical friction to generate heat and join metals without filler. Explosive welding accelerates one metal at high speed into another. Laser beam welding uses a concentrated laser heat source to make narrow, deep welds. Plasma arc welding uses an electric arc and constricted plasma to reach very high temperatures. Resistance welding generates heat through electrical resistance to join metal sheets. Thermite welding uses a thermite reaction to melt and join metals. These techniques are used in automotive, shipbuilding, aerospace and other industries.

Gas and other Welding Shailesh Dewangan.pptx
This document discusses various welding and metal joining processes. It describes gas welding (oxy-acetylene welding) where a flame is used to heat and join metal parts. Resistance welding uses electric current to heat and join metals under pressure. Solid state welding techniques like friction and ultrasonic welding join materials without melting them. The document also covers soldering and brazing which use filler metals to join parts through capillary action without melting the base metals.
resistance spot welding
Resistance spot welding is a process that joins metal parts using heat generated by resistance to current passing through the workpieces. It is commonly used in automotive and aircraft manufacturing. Key advantages are its speed, ability to join thin sheets, and suitability for automation. However, it requires specialized equipment and skilled operators, and is generally not suitable for thick materials. Electrodes must conduct current efficiently while withstanding heat and pressure. Copper alloys are commonly used but refractory materials may be required for some applications like welding stainless steel.
ELECTRICAL WELDING
Electric welding involves joining metals through heat generated by an electric current. There are several types of electric welding processes. Resistance welding uses high current to heat and join metals at points of contact between electrodes and generates heat based on resistance. Arc welding uses an electric arc to melt metals and can use consumable or non-consumable electrodes with shielding gas. Carbon arc welding is a process that produces coalescence of metals by heating them with an arc between a non-consumable carbon electrode and workpiece.
welding process.pptx
Welding is a process for joining metals using heat. Arc welding uses an electric arc to generate heat and melt the metals, which fuse together upon solidification. Flux shielded metal arc welding (SMAW) uses a consumable electrode coated in flux that decomposes to protect the weld area from contamination. When an arc is struck between the electrode and workpiece, the electrode melts and deposits filler metal into the weld joint. SMAW is versatile and can weld many metals, but uses consumable electrodes and produces slag, so defects can occur during restarting welds.

Introduction to solid state welding processes
- 1. Introduction to Solid-State Welding Processes Welding joins metals through different ways. From arc to oxyfuel, there are various techniques to fasten metal pieces together to create unique products. Contrary to popular belief, not all welding processes have to melt the metal. One such way of forming metal pieces without increasing the temperature is through solid-state welding, and there are different techniques under this branch too. Here are some of them: Coextrusion Coextrusion welding forces dissimilar metals through the same die. Practical application of this includes blending corrosion-resistant and cheap alloys together. Cold pressure Through cold pressure, copper, aluminium, and similar soft alloys are formed under their melting point. This is a great technique in manufacturing electrical contacts.
- 2. Explosion Explosion welding is one of the more recent techniques. Developed only after World War II, this uses chemical explosives to weld metals together. Common applications include cladding a steel plate with a layer of corrosion-resistant material, bimetal pipelines, and shipbuilding. Diffusion Diffusion welding heats metals to around 50-70% of the melting point to coalesce them together. This technique does not yield weld lines. The electronics, aerospace, and nuclear industries use this process. Electromagnetic pulse Electromagnetic pulse welding joins two pieces together through the use of strong magnetic forces. Similar to explosion welding, this technique accelerates tubes and sheets to merge, and expels oxides upon impact. Pressure vessels and cars have parts made through this process.
- 3. Hot isostatic pressure Hot isostatic pressing is a notable manufacturing process that uses high temperature and isostatic gas pressure contained inside a high-pressure vessel. As a result, the gases – which are inert, to avoid chemical reaction – apply pressure on all directions to form the metal and weld it. While this technique reduces the porosity of metals, it improves the workability and mechanical properties of the material. Roll Roll welding uses two rotating wheels. The work piece goes in between the wheels, and they are joined together through force. Ultrasonic Ultrasonic welding uses pressure and high- frequency vibrations to apply force to workpieces and join them together. This is a common technique in plastics, and metal sheets, and in foils found in the automotive, electronics, and solar industries. The different techniques of solid-state welding show that metals do not have to reach melting point to be formed according to a desired shape. These are just some processes under solid-state welding, and there are more that can yield interesting results.
