IRJET- Evaluation of Ernicrfe-7A Filler Wire for Dissimilar Welding of SS304H...IRJET Journal
This document evaluates the weldability and mechanical properties of dissimilar joints between stainless steel SS304H and steel T91, welded using an Inconel filler wire. Hot-wire gas tungsten arc welding was used to weld specimens with varying parameters. Microstructural characterization found increased hardness near the T91 fusion boundary. Tensile strength of cross-weld specimens at high temperatures was similar to T91 but higher than SS304H. Bend testing found no defects except a 1.93mm opening in one specimen, within acceptance criteria. The welding technique is suitable for joining SS304H and T91 for applications like advanced supercritical boilers.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

WHAT IS EXOTHERMIC WELDING
Exothermic welding, also known as exothermic bonding and is a welding process for joining two electrical
conductors, that employs superheated copper alloy to permanently join the conductors. The process
employs an exothermic reaction of a copper thermite composition to heat the copper, and requires no
external source of heat or current. The chemical reaction that produces the heat is an aluminothermic
reaction between aluminum powder and a metal oxide.
The reaction reaches very high temperatures, depending on
the metal oxide used. The reactants are usually supplied
in the form of powders, with the reaction triggered using a
spark from a flint lighter. The activation energy for this reaction
is very high however, and initiation requires either the use of
a “booster” material such as powdered magnesium metal or a
very hot flame source. The aluminum oxide slag that it produces
is discarded.
When welding copper conductors, the process employs a
semi-permanent graphite crucible mould, in which the molten
copper, produced by the reaction, flows through the mould
and over and around the conductors to be welded, forming an
electrically conductive weld between them. When the copper
cools, the mould is either broken off or left in place. Alternatively,
hand-held graphite crucibles can be used. The advantages of these
crucibles include portability, lower cost (because they can be
reused), and flexibility, especially in field applications.
The weld formed has higher mechanical strength than other forms of weld, and excellent corrosion
resistance. It is also highly stable when subject to repeated short-circuit pulses, and does not suffer from
increased electrical resistance over the lifetime of the installation. However, the process is costly relative to
other welding processes, requires a supply of replaceable mould, suffers from a lack of repeatability, and
can be impeded by wet conditions or bad weather (when performed outdoors).
FEATURES
It has a superior electrical conductivity than the conductors themselves.
It does not corrode oxide or degrade with time and is resistant to galvanic coupling.
It is able to withstand repeated electrical discharges.
It never increases its resistance.
It has higher mechanical and squeezing resistance than the conductors themselves.
It offers a permanent welding and a low resistance connection, essential for achieving
longwearing and trustworthy results in earthing.
It guarantees the most common connections not only between copper cables but also for welding
tapes and metallic pieces made of brass, stainless steel, and copper coated steel earth rods.

B. Do not connect items except as detailed in instruction sheets. Failure to comply with these instructions
may result in improper and unsafe connections, damage to items being welded or even injury to body or
property damage.
C. Do not use worn or broken equipment which could cause leakage. Sealing compound should be used
in case of fine leakages.
D. When using Weld do not use welding material package if damaged or not fully intact.
E. Make connections in conformance with instructions and all governing codes.
F. Personnel should be properly trained and must wear safety glasses and gloves.
G. Avoid contact with hot materials.
H. Advise nearby personnel to stand at least 7 to 10 Foot away of welding operations site.
I. Remove or protect the inflammable material from the operation site to safeguard against fire hazards.
J. Provide adequate ventilation to the work area.
K. Do not smoke when handling starting material.
L. Avoid direct eye contact with “flash” of light from ignition of starting material.
F. Welding material is an exothermic mixture and reacts to produce hot molten material with temperatures
in excess of 1400°C (2500°F) and a localized release of smoke. Ignition temperatures are in excess of
900°C (1650°F) for welding material. These materials are not explosive.
G. Adhering to the welding procedures will minimize risk of burns and fire caused by hot molten material
spillage. In case of fire, use of water or CO2 will aid in control of burning containers. Large quantities of
water will aid in controlling a fire should the exothermic materials become involved. Water should be
applied from a distance.
H. All governing codes and regulations and those required by the job site must be observed. Always use
appropriate safety equipment such as eye protection, hard hat, and gloves as appropriate to the
application.
WARNING :
1. Products shall be installed and used only as indicated in product instruction sheets.

TOOLS REQUIRED FOR EXOTHERMIC WELDING PROCESS
1) Graphite Mould
Graphite mould is made of high quality graphite suitable for
high quality welding work and can be used for several times.
The exothermic welding reaction takes place in a specially
designed, semi‐permanent graphite mould. The mould is
designed and manufactured with a specific weld cavity and it
is in this cavity that the molten metal is allowed to flow to all
sections of the required connection creating the permanent
connection. The connection mould is designed to last for an average of 30 to 100 connections depending
upon the amount of Powder used per Joint (More the Powder Consumption per Joint, less will be the
Connection & vice versa) . This will also vary according to the care given the mould during use. We
recommend not using Mould for more than 60 to 70 Connections because the Weld cavity Size increases after
every joint, eventually making the Weld Cavity shape improper resulting in improper shape Joint.
2) Mould Handle Clamp (HCC/HCD)
These will fit 90% of all standard exothermic Mould.
Normally we recommend one Handle for every two mould
3) Steel Metal Disk
Steel discs are very important. The disc act as timing device to allow
the welding powder to heat to proper temperature, the disc away
allowing the molten copper to a point where it would weld metal to
enter the weld gravity before ignition. One Metal is must for every shot
4) Exothermic Weld Powder
Exothermic Weld Powder isthe most reliable and consistently-performing
weld metal available with us. Quality validation steps are taken for
every lot we produce. Upon final acceptance, our weld metal isspecially
packaged in moisture-resistant plastic tubes with special closure caps.
Then the cartridges and required metal discs are packaged in
moisture-resistant boxes. All sizes of weld metal are available.
Standards Size Packing available are – 25 Grams, 45 Grams, 90 Grams 1.1 1.2
115 Grams, 150 Grams, 200 Grams, 250 Grams, 250 Grams,
Our standard packing for welding powder is the following - Firstly welding powder is in the tube and
starting powder / Ignite Powder is in tube at the bottom of welding powder as shown in diagram 1.2.
5) Ignite Powder (Starting Powder)
Ignite Powder also known as Starting Powder is required and is must. Pour little
Starting Powder on the Mould followed by the Exothermic Weld powder and again
pour little on the Top Side of Mould. Then, Ignite starting powder with a spark gun.
This resulting exothermic reaction reduces the weld powder to molten copper alloy. The molten copper alloy
melts the retaining disc and flows into the weld cavity. Ignite Powder of 5 grams is sufficient for this Process.
7. AmiableWeld. Email: info@exothermicweld.com Tel. +91-9594899995 URL– www.exothermicweld.com
Page 7 of 20
6) Hand Gloves (HG)
Gloves is required for safety purpose as the Exothermic Weld Powder melts
at more than 1400 degree Celsius. One Hand Gloves Good for 250 Joints
7) Flint Gun (FIG)
It is designed with the advantages of safety and convenience. It is used to ignite
starting Powder in order to result in exothermic reaction.
We recommend one Flint Gun for every 80 Shots
8) Brush (Soft and Hard) (SHB)
Two Brush Required:
1) Soft Brush – Its used to Clean Mould Weld Cavity because its shape
is very sensitive and cavity should not be any damage while using Brush,
so we recommend to use Soft Brush to Clean Mould Weld Cavity
2) Hard Brush – Its used to clean other section of Mould
We recommend a Pair of Brush for 50 Connection
9) Slag Removal Tool (SRT)
It is used to remove the metal Scrap and Dust from the Mould.
We recommend one Slag Tool for 250 Connection
10) File Card (FCB)
It is used to clean the objects to be welded to remove rust and dirt
We recommend one Slag Tool for 100 Connection
11) Sealing Compound (SCD)
Sealing Compound is used to fill the gap on the mould where the conductor is passing.
We recommend one Packet of Sealing Compound for 100 Connection
12) Flame Torch (FT)
Sealing Compound is used to fill the gap on the mould where the conductor is passing.
We recommend one Flame Torch for 250 Joints
13) Safety Eye Glasses (SEG)
Safety Eye Glass should be wear to protect eyes.
We recommend one Glasses for 500 Joints

EXOTHERMIC WELD OPERATION PROCESS
The Exothermic Weld process is a method of making electrical connections of copper-to-copper or copper-to-
steel in which no outside source of heat or power is required. In this process, conductors are prepared, placed
in a purpose designed graphite mould, and exothermically welded to produce a permanent molecularly
bonded electrical connection. The steps outlined below are a general demonstration of a typical welded
connection. These basic steps are used for all electrical connections. Be sure to read and follow the
instructions included with every Mould before making a connection.
STEP - 1:
Always wear protective safety glasses and gloves while working with exothermic welding products.
STEP - 2:
Gather all the proper material and equipment/accessories for the type of connection you are making. The
typical Weld system requires all the Accessories as listed above on Page no. 04 and Page no. 05.
Check to ensure the graphite Mould is not worn or broken, which could cause leakage of molten weld metal.
STEP - 3:
Slide the handle clamp into the pre-drilled holes with the proper orientation for the thumbscrews.
STEP - 4:
Tighten the clamp thumbscrews onto the mould.
STEP - 5:
Close the grips to tightly lock the Mould. Make adjustments to tighten/loosen the handle clamp.
STEP - 6:
The material to be welded (cable, rod, tape etc.) must be clean using the wire Brush and dry using the Flame
Torch included in the set of accessories. Thus the oxide layer and superficial impurity is eliminated. Given
that the graphite mould also absorbs moisture, this should be removed by preheating with a gas welding
torch again to avoid a porous welding.
P.N - After the first welding is done, it is not necessary to re-heat the mould if the next welding is done
within 15 minutes as it conserves the previously generated heat.

Page 9 of 20
STEP - 7:
Place the conductors in the mould and close the handle clamps to avoid material leakages during the
reaction.
Please Note – Always apply Sealing Compound at the places where the conductors is passing from the
mould else at the time of Welding, the Exothermic Liquid will spread out as a flame resulting in improper
joint
STEP - 8:
Place the metallic disk inside the mould and ensure that Powder should not enter into Weld Cavity.
STEP - 9:
Pour Exothermic Weld Powder into Graphite Mould. (Pour the Powder recommended and supplied by us)
STEP - 10: Empty 50% of the starting powder above Exothermic Weld Powder (Don’t Mix, just scatter) and
then Close the Mould Mouth and then the rest 50% Starting Powder, sprinkle it on the Mould Mouth nearby
the small hole given on the top of the Mould Mouth.
STEP - 11: Ignite the starting powder extended on the top/side of the mould using the flint igniters.
STEP - 12: Once started, the reaction will take 8-20 seconds during which it is recommended to stand clear
of the mould.
STEP - 13:
After at least 3 minutes of the Mould cooling down, open the mould
by undoing the handle grip. Remove the mould from the joint and
clean the joint by removing slag with help of Slag Removal Tool
and hard brush. Then clean the weld cavity with soft brush gently.
The mould will be ready now to use again without having to reheat
it as it is already warm.
Note:
In Normal case minimum two mould should be used on site to keep the process continue while one mould is
cooled and cleaned after firing, the other should be used. The task should be undertaken very peacefully
and one should not hurry.
