Abstract
This report identifies the basic concept of MIG welding on simple carbon steel (Thickness=
2mm). By the support of the process of MIG, welding application finds out microstructure of
the steel. When the inert gases are used in the welding of MIG on that time connection of the
stainless and carbon plat should be improved. During the treatment of heat application in the
welding of MIG diameter of 2 mm, steel plat should be mould. Cause of the changes of
voltages in the welding of MIG microstructure of the simple carbon steel (Thickness= 2mm)
is change.
When the hardness test is applied to the carbon steel at that time microstructure of the carbon
steel (Thickness= 2mm) should be reflected. Steel of carbon is used in the structure of
material for less corrosion capability. With the cause of the effective material bound between
the microstructure of carbon steel (Thickness= 2mm) effect of applied stress in a tensile
position should be less. When the rate of the supply voltage should be increased on that time
rate of welding penetration should be high. High penetration provides an effective joint
between the materials. During the process of welding (MIG) in carbon steel (Thickness=
2mm) rapidly change the microstructure. Voltage change in the process of welding (MIG)
working efficiency should be less. Zone of heat-affected in simple carbon steel is generating
high strength capacity with low microstructure change.

Introduction
Simple steel of carbon is basically used for the purpose of industrial work structure. When the
Process welding process of MIG is used in the simple carbon steel (Thickness= 2mm) on that
time strength of the workpiece should be increased. Voltage change parameter should
increase the load capacity. If the inter gas flows in the welding of MIG and voltage structure
should be changed on that time received the fused result and workpiece of is break during the
applied load. This report justifies the stress of tensile during the process of MIG welding
without flow the supply of inters gases.
Background: Steel of carbon is the material by the support of them easily handled the
process of welding with less effect of material microstructure. During the process of heat
treatment annealing of the material is rapidly change the cooling structure of the carbon steel
plat (Thickness= 2mm). Property of the surface structure is analysis by the use of the stress
factor in the tensile direction. By the use of test of hardness in the carbon, metal plat
determines the level of microstructure during applying the load. If the voltage supply should
change on that time composition of chemical (filler material) microstructure of plate is
change and workpiece of carbon steel plat (Thickness= 2mm) is broken.
AIM: The basic aim of the welding of MIG application is to find out the strength of the
workpiece (simple carbon plat, Thickness= 2mm). By the support of the welding of MIG
protocol with a supply of inert gas, without a supply of inter gas, voltage change and change
the speed of feed during the welding process analysis the rate of hardness and Yield point
application. By the support of the application of filler material distortion of joint in the
carbon, plat should be reduced. Testing of electrochemical with voltage model WPG100
determine the basic microstructure of specimen (simple carbon plat, Thickness= 2mm).
Objective: In the process of welding of MIG application use the stainless steel electrode as a
component of filler material. If the gas of inert is flow in the process of welding (MIG) on
that time joint should be getting more strength compared to the without inert gas flow
application in the welding of MIG. Characteristic of surface structure is analysis by the use of
the material of filler for the welding of MIG. If the use the 10v voltage with the support of the
4.8mpm on that time fused should be not in a proper manner. Less penetration during the
welding process of MIG analysis the voltage structure on the simple carbon plate
(Thickness= 2mm).
Specification Requirement: For the welding of the MIG application required the steel of
stainless electrode for a joint application. Use the effective penetration application increase
the work structure of metal steel carbon piece (Thickness= 2mm) to analysis the range of the
test of hardness and stress of tensile direction. Use the different voltage parameter to justify
the effective fused in the work structure. Provide the effective manner inner gases to achieve
the effective strength during the welding (MIG) process with the simple specimen of steel of
carbon (Thickness= 2mm). When the voltage should be change at that time rate of
penetration through electrodes should be improved.

Literature Review
According to Bunaziv et al. 2018, In the process of welding for MIG identify the supply of
voltage with a different parameter of penetration. When the use gas of inert for welding
application in MIG justify the microstructure of specimen of steel carbon piece (Thickness=
2mm) changes the microstructure metal piece. If the working range of the voltage is 15.6v for
the 2mm thickness of simple carbon piece fused rate should be properly. The penetration
range of the electrode should be increased due to the welding (MIG) application. If the gas of
inert is not used in the welding application in MIG on that time microstructure of the work
specimen (simple carbon steel, Thickness= 2mm) is completely change. If the working range
of the voltage is 15.6v for the 2mm thickness of specimen range of working penetration is
high. During the process of welding application with the MIG process (not use inert gas)
generate the holes in the surface structure of the specimen (simple carbon steel, Thickness=
2mm) [5].
Generated holes on the surface of the carbon steel specimen (Thickness= 2mm) reduce the
strength of the workpiece. When the load is applied to the specimen on that time during the
stress of tensile work material should be break. When the voltage range is 10v on that time
joint fused is not created properly between the workpiece and penetration rate of the welding
process (MIG) should be hampering. When the voltage range should be an increase in that
time capacity of penetration should be increased but create the different changes in the
microstructure of metal piece [1].

According to the Ambekar et al. 2015, a test of hardness is the protocol by the support of
them identify the strength of the workpiece or specimen (simple carbon steel, Thickness=
2mm). With the cause of the welding application of MIG process increase the microstructure
of the workpiece and reduce the hardness of metal piece thickness = 2mm. On behalf of the
length of workpiece (Carbon steel) protocol of tensile stress should be improved. If the length
of workpiece is high on that time creation of the hole in the surface specimen is less and the
application of hardness of work material should be increased. When the rate of the supply
voltage should be changed at that time application of the welding penetration is effective [2].

If the length of a workpiece (Carbon steel) is less on that time generation of a hole in the
microstructure of workpiece surface should be high and the rate of the hardness test should be
reduced.
If the inert gas is supply on welding of MIG for the specimen (simple carbon steel,
Thickness= 2mm) on that time speed rate is 4.8mpm on that time penetration should be in a
proper range and generation of the holes in the structure of specimen is less. Due to this
application rate of the material finishing should be high and the effect of hardness test to
finding the strength is high. If the inert gas is not supplied on that time voltage range is high
approx 15.6v on that time penetration effect should be in a proper manner and reduce the
generation of a hole in the work surface of the specimen (simple carbon steel, Thickness=
2mm) [3].

According to the Babu et al. 2016, Composition of the electrode chemical for the welding of
MIG application is very effective to make the strong joint distortion. For the specimen
(simple carbon steel, Thickness= 2mm) 7OS-6 material of filler for an effective bound
generation. In the application of welding of MIG protocol use the steel of stainless to
generating the powerful join in the metal piece. By the support of the electrode, application
fills the gap between the joint of specimen application. Zone of heat treatment in the
specimen increases the connectivity of metal piece for joining. If use the filler gas like argon
and CO2 on that time for the thickness of 2mm and speed is 2 m/min on that time angle of
welding penetration 90 angles on that time distortion of the joint should be high [4].
If not use the inert gas for the process of welding of MIG and welding penetration is also 90
angles on that time rate of distortion for the metal joint should be less. Filling the material by
the support of the material of filler identify the range of microstructure on the surface of the
workpiece. When the specimen should be cold in the room temperature on that time testing of
electrochemical is to identify the rate of the specimen microstructure.

According to the Cevik et al. 2019, application of inert gas supply and without inert gas
supply welding arrangement for the MIG application for the requirement. By the support of
the inert gas process of welding weld the metal of non-ferrous for an effective joint
application. Use the helium and argon gas component for the application of an inert gas
process of welding function. For the specimen (simple carbon steel, Thickness= 2mm)
generated the high-temperature welding zone for proper joint of work material. By the cause
of the inert gas welding for MIG, application uses the short arc for a generation of the fewer
holes in the microstructure of the specimen. When the inert gas welding (MIG) is used at that
time the generation of slag is reduced and capacity of joint of a metal piece should be high
[8].
If the without inert gas application of welding (MIG) is used for the specimen on that time
use the flux wire for filling the gap between the workpiece. By the cause of the without inert
gas, application generates the slag on the work surface of the material. When the slag is
generated on the specimen thick 2mm with simple carbon steel on that time rate of the
microstructure deflection should be increased. By the cause of the without inert gas welding
application generation of slag is reduce and improve the work structure work specimen
(Carbon steel plate, thickness 2 mm) for the find the hardness test [6].

According to Chen et al. 2018, microstructure of work-piece is dependent on the generation
of slag, rate of the metal distortion for effective joint. A fraction of slag application is
defining the rate of slag with an effective microstructure of the application. The calculation of
the test of hardness application totally depends on the microstructure of the workpiece
(simple carbon steel, Thickness= 2mm). If the provided voltage is 15.6v for the thickness of
2mm sheet of metal and feed rate is 4.8 mpm on that time create the different type of the hole
on the surface structure of carbon steel specimen (Thickness =2mm). Due to the generation of
slag in the surface of metal piece microstructure of the piece should be changed and it totally
hampers the hardness of the work material [9].
When the speed of the supply voltage should be an increase at that time rate of the welding
penetration should be hampering on the basis on the speed of feed. If the microstructure of
the specimen (simple carbon steel, Thickness= 2mm) should be change on that time
according to the rate of the microstructure application find out the strength and stress capacity
of the workpiece carbon steel specimen. When the rate of the supply voltage should be
increased on that time rate of welding penetration should be high. High penetration provides
an effective joint between the materials. By the support of the different type of er material
application increase the rate of the slag generation of change the microstructure application.
When use the Al, Mg and Fe for the generation of the filler material application on that time
rate of the slag generation should be changed. A fraction of slag application is defining the
rate of slag with an effective microstructure of the application [7].

Methodology
MIG welding is the welding application by the support of them joint the different type of the
ferrous or non-ferrous allows with strongly. For the specimen of simple carbon steel
(Thickness = 2mm) use the different type of methodology function to join the workpiece.
(1) For without inert gas MIG process of welding: In this welding application by the
support of the feed the consumable electrode with suitable feed speed. For the specimen of
simple carbon steel (Thickness = 2mm) use the aluminium as a filler wire to join the gap
between the provided specimen. When the without inert MIG gas welding is extract on the
specimen (Thickness = 2mm) on that time due to the cause of the aluminium alloys provide
the strong joint during the welding application [10].
Working: By the support of the inert gas electrode application provide the suitable heat zone
17.55 KJ/mm and range of the voltage is 15.6v. In this welding, application used the
aluminium as a filler wire to provide a suitable joint. Filler material feed rate is 4.8 mpm to
fill the joint gap. By the support of this application gain the effective fused joint in the surface
of the specimen (Thickness = 2mm). Without inert gas MIG process is very simple and
without slag generation process. In this process any type of the slag is not generated in the
surface of the specimen of simple carbon steel (Thickness = 2mm). By the support of the
without inert gas MIG process of welding provides the effective joint and gain fewer changes
in the microstructure of the specimen of simple carbon steel [13].
Test result: When the test of hardness is applied to the weld specimen at that time due to the
fewer defects value of the hardness application should be high. The capability of the stress in
tensile direction is also high because of low/no defects on the surface of the work material.
The surface of the weld specimen provides the less amount of fracture during the process of
without inert gas MIG welding application. Due to the cause of the aluminium filler material
bonding of the specimen joint should be very high. Aluminium filler material generates less
amount of slag on the surface specimen of simple carbon steel (Thickness = 2mm). When
select the aluminium material on that time maximum load on the specimen is 8395N. Load
break extension is 10.103mm during the selection of the aluminium material [15].
(2) With inert gas MIG process of welding: With inert gas MIG process of welding is the
application in which by the support of the supply of inert gas (Argon, Helium) provide the
effective joint on the surface of the specimen of simple carbon steel (Thickness = 2mm). In
this welding application by the cause of the supply of the inert gas high amount of slag is
generated on the surface of the workpiece. When the inert gas MIG process of welding is
done on the specimen on that time large amount of the slag is generated on the surface of the
workpiece. Due to the cause of the slag generation value of the hardness test and capacity of
stress in tensile direction should be decreased. In the inert gas MIG process of the welding
basically, use the argon gas component for generated the heat zone [11].
Working: In this process by the support of the different supply rate of voltage manage the
welding application. For the specimen of simple carbon steel (Thickness = 2mm) firstly set

the voltage is 10v during this application effective heat zone is 11.25 KJ/mm. In this welding
situation specimen of simple carbon plate (Thickness = 2mm) cannot weld properly or not
fused the welding application. When the supply rate of the voltage (15.6 V) should be
increased on that time generated the large area of heat zone (17.55KJ/mm) in this welding
condition specimen of simple carbon plate (Thickness = 2mm) weld properly or fused with
effective manner. By the support of the MIG inert gas welding process use the argon or
helium gas for created the effective heat zone. Due to the cause of the high heat zone amount
different type of defects is generated on the surface of the specimen of simple carbon plat
[14].
Test result: When the inert gas MIG process of welding is done on the specimen of simple
carbon plat (Thickness = 2mm) on that time slag or defects is generated due to welding
application. By the cause of the defects or holes generation different type of the fracture is
created on the microstructure of the specimen. When the test of hardness is applied on the
weld specimen of simple carbon steel (Thickness = 2mm) on that time value of test of
hardness is reduced. If fine the stress capability on the surface of the work material of weld
specimen of simple carbon steel (Thickness = 2mm) provides the less value [12].
(3) Voltage change and feed speed change with an inert gas: Rate of voltage change and
rate of feed speed change with inert gas play an import role for providing the effective weld
joint. When the rate of the voltage should be changed on that time rate of the welding
penetration should be fluctuated. If the supply of the voltage range is high on that time rate of
the welding penetration is high and if the supply of the voltage range is low on that time rate
of the welding penetration is low. By the cause of the high welding, penetration rate provides
an effective joint on the surface of the workpiece [17].
When the rate of feed speed should be changed on that time changes on the microstructure of
the workpiece should be obtained. When the feed rate is low and inert gas is flow on that time
rate of the weld fused is not in a proper manner. If the feed rate should be increased in supply
voltage should be increased at that time rate of the weld fused is in a proper manner.
For the specimen of simple carbon plat (Thickness = 2mm) firstly set the 10V for welding
application. Due to the cause of the 10V supply generated heat zone is 11.25KJ/mm on the
surface of the specimen of simple carbon plat (Thickness = 2mm). When the voltage range is
increased it should be 20V on that time create the 22.16 KJ/mm heat zone on the surface of
the specimen of the simple carbon plat (Thickness = 2mm) [19].
Result analysis: During this welding process on the specimen of simple carbon plat analysis
if the voltage range is low on that time created the less heat affected zone and if the supply
rate of voltage should be increased on that time generated the high heat-affected zone on the
surface of the specimen. Due to the high heat zone on the surface of specimen created a large
number of defects on the surface structure of the material. When the defect is generated on
the surface of the specimen of simple carbon plat (Thickness = 2mm) on that time value of
the test of hardness should be decreased. When determining the stress on the weld specimen
surface due to the cause of the defects value the stress in a tensile direction should be low
[18].

For the specimen (Thickness = 2mm) adjusted the 3.8 mpm feed rate with a supply of the
15.6 voltage. When the feed rate is 3.8 mpm and inert gas is flow in the process of welding
on that time fuse is not done properly. By the cause of the feed rate application analysed the
speed of welding penetration. If the feed rate should be increased (5.8 mpm) with the same
supply of voltage on that time rate of the welding fuse is properly [16].
Result analysis: During the process of welding on the specimen of simple carbon plat
analysis if the value of the feed rate should be an increase on that time rate of the welding
penetration is also increase and provide the effective welding application on the surface of the
specimen of simple carbon plat (Thickness = 2mm). If the value of feed rate should be
decreased or low at that time rate of welding penetration is also decrease or low. When the
penetration rate is low on that time not provide the effective welding on the surface of the
specimen of simple carbon plat (Thickness = 2mm). Welding penetration is a very important
part of the welding (MIG) process. By the support of the penetration application identify the
accuracy of the welding process. Goog penetrations in the MIG process of welding provide a
high accuracy rate. Less penetration in the MIG process of welding provides a less accuracy
rate. By the cause of the different feed rate application provide the different welding
application. Good rate of feed with a supply of inert gas provides the effective welding
application on the surface of the specimen of simple carbon plat (Thickness = 2mm) [20].
MIG process of welding is the basic generation of the welding application. By the support of
the MIG application on the surface of the specimen of simple carbon plat (Thickness = 2mm)
provide the effective welding joint. When the application of welding is done on the surface of
the specimen of simple carbon plat on that time due to the cause of the heat-affected zone, the
microstructure of a specimen should be changed. When the less heat amount zone is created
on that time changes on the microstructure of specimen surface should be less. If created the
high amount of heat amount zone on that time generated the large changes on the
microstructure of specimen of simple carbon plat [22].
Changes in feed rate and supply rate of voltage are the also basic parameter of welding
application. When the rate of feed should be decrease at that time process of welding not
done properly. If the rate of feed rate increases on that time process of welding is done
properly. If the supply of voltage should fluctuate on that time cause of different voltage
Defect during the high heat zone
