Mechanisms of MIG and TIG welding
This is an arc welding process in which the joining aspect is generated by heating the work on
the metal to be joined. The welding hardware comprises of predominantly welding force source,
links, wire feed instrument having pair of wire driving rolls and electric engine, welding firearm
and wire anode wound spool, dormant protecting gas chamber, and weight controller, stream
meter controls to manage the present, terminal wire and gas(Palanikumar,Latha,Senthilkumar &
Davim 2012).
The welding weapon comprises of two current channels for protecting gas and a wire manage
tube which is gone through welding spout. Not at all like TIG welding where non-consumable
filler bar is utilized, MIG welding utilizes consumable filler material on the metal work piece.
Likewise, welding light is supplanted by welding weapon in this kind of welding to sustain guide
current to the metal work piece. The welding weapon which holds and feeds the anode and gas
might be air-cooled or water-cooled. The spout utilized can be either straight or slanted for
accommodation to weld complex shapes and unpredictable joints (Mueller 2012).
These two kinds of the welding are affected by the angle of the weld and also the availability of
the stable temperature to ensure that the weld does not take a different form
Elaboration of the areas of application of the MIG welding
As a trade for the age-old stick welding technique, MIG welding is undoubtedly a standout
amongst the most effective welding shapes in the business, and it happens to be an acronym for
Metal Inert Gas. The circular segment is struck between the tip of the wire as it rises up out of
the light, and amid this procedure a protecting gas will be radiated in light of a legitimate

concern for forestalling oxidation. Most MIG welding sets give a setting that allows the wire
speed to coordinate the voltage, and one of the greatest advantages is the usability
The areas of the applications of this kind of welding include the sector of the motor vehicle
repair. The repairs can be on any vehicle whether small or large.
MIG/MAG welding is utilized in little repair shops or organizations, as well as in huge parts of
the welding business. For instance, in the assembling procedure of pipelines this strategy is as
important as in the ship building industry, sheet metal industry, and the generation of weight
vessels or steel structures. Not to neglect to say the car business and the utilization in the home
change part.
As adaptable MIG/MAG welding seems to be, so confounded it can now and then be. In any
case, it is as of now the most broadly utilized welding process. MIG/MAG welding is a
mechanical insurance gas welding technique, where an electric circular segment, affected by
inactive gas, consumes between the wire terminal and the work piece. The mechanical included
wire cathode will be utilized as filler material; it softens amid the welding procedure in their own
electric circular segment. Contingent upon which materials are handled separately, extraordinary
gases or gas blends can be utilized in MIG/MAG welding.
As opposed to the metal inactive gas welding, where a functioning protecting gas is utilized
when welding certain materials, amid Metal dynamic gas welding a functioning defensive gas,
for example, carbon dioxide or argon-carbon dioxide blends is utilized. This is proposed to
ensure the fluid weld pool against outside impacts.
Examples of MIG welding

Figure 1: sample of MIG welding (Mueller 2012).
The TIG welding is used in the places that need hard facing. It has been used in the
reinforcement of the worn out surfaces .In the cases where the two surfaces cannot be joined,
proper fillers can be used to achieve the objective (Venkata & Kalyankar 2012).
Zones of utilization
TIG welding is frequently utilized for occupations that interest brilliant welding, for example:
Areas of application TIG welding is often used for jobs that demand high quality welding such as
for instance:
• The offshore industries for ship building
• Combined power and heat plants
• The petro -chemical industry
• In the food industries
• In the chemical industries

• In the nuclear industries

DESCRIPTION OF TYPE OF CONTROL

HAZARD AND
SAFETY
ISSUE
SUGGESTED
SOLUTION TO
HAZARD
1 Eye damage: welding
normally creates
sparks that pose
physical hazard to the
operator
Use of the protective
goggles and dark
shades
Wash eye with
enough water and
Perform first aid
2 Chemical exposure:
Exposure to chemicals
like argon, carbon
monoxide may expose
the welder to
breathing
complications
Exposure to chemicals
like carbon monoxide
gases can be
prevented by use of
the proper ventilation
Use of nose masks
may help
In case of suffocation
of the carbon
monoxide gas victim
in a properly
ventilated area and
perform first aid
3
Arc flash: it ban result
into the burning effect
through ultra violet
radiation
Use of personal
protective
equipment’s including
the gloves and aprons.
Perform first aid in
the cases of burn.
4 Fire Hazards: sparks
from the welding may
cause fire that can
consume the whole
workshop
Keep inflammable
materials away from
the welding area.
Clothes of the welder
should be free from
the grease.
Use of the fire
extinguishers
5 Electric shock: It is
usually generated
from the necked wires
Clothes and gloves
should be in dry
condition
Insulation of the
welder from the

During the workshop operation, I found the following safety precautions to be useful:
 The welding should not be done in a room that has got wooden floors. If this has to be
done then floors must be protected with means of the fabric that is resistant to fire.
 The hot metals that have been welded must be marked using soapstone
 Always ensure that there is a very suitable fire extinguisher nearby all the times.
Welding is very important activity in the today life. In the ship building for example the main
strategy is weld repair and any failure of the welding system will definitely lead to the sinking of
the ships. In the building and construction industries, welding has enabled joining of the metals
while retaining their strength.Welding has therefore ensured that the engineering strengthen of
the materials are maintained (Meena, & Azad 2012).T
The welding is done to ensure that the engineering properties of the materials are not
compromised during their applications. The areas of applications will include those that requires
high safety standards like for the case of the of ship building. In the workshop I was able to
confirm some of the importance reasons why welding is done.
Welding has been found to be one of the most critical activities that are used in the everyday life.
In the ship building for example. Whenever there is a failure in the system of welding then it is
very definite that the whole system will fail. Some of the processed of the welding have been
fabricated so the operators only need to counter check what they have done against what has
already been set. The expectation of the quality of the weld has never been higher. From the
work that I did in the workshop, a number of methods were used and various safety standards
were followed to ensure that there were no injuries and damages in the prices.

My work in the workshop was guided by several safety measures that I found very useful. The
safety measures included the following:
 Always ensure that any assemble part that may lead to mistaken welding
 All flammable materials should not be kept in the workshop for welding
 Never leave a hot rejected electrode stabs on the fire since fire can easily occur.
Welding has got very many benefits in various places in the handling of fuels and other
components of the petroleum, proper welding will ensure that there are no leaks that can easily
results into the accidents. In the building and construction industries, there is need to use very
lengthy structures without interfering with their strengths and properties. In order to achieve this,
the welding process must be used (Kumar, Maheshwari, Sharma, & Beri 2012).
 To maintain the properties of the construction materials
 To join two or more parts that would otherwise been difficult to achieve using other
methods
 It is a means of repairing components
Welding is basically used in the building and construction sectors where they play a major role in
ensuring that safety is maintained. In the workshop, there was provision of the materials that
allowed for the practicing of the welding. The importance of welding and how to come up with a
perfect weld was properly covered. The possible safety measures that are required during
welding were properly observed. It was generically a perfect moment to gain experience.
