INTRODUCTION
Originally Inert Gas Tungsten Arc Welding (Tungsten Inert Gas)
is a type of arc welding made the atmosphere control. Tungsten
electrodes were used. Electrodes only to produce an arc only. So
for the weld when the metal Additional required to weld, trunk
filler rod should be fed to the weld area as methods done in
oxy-gas welding process asetilina.During the welding process is a
shield in the form of gas inert (argon & helium) is used to
block the welded from atmospheric air. Shield works for prevent
oxidation at the electrode tip, a puddle weld and the parent metal
in the vicinity of the welded. There are two types of commonly used
welding nozzle weld TIG operation manually. For welding use per
current is low (less than ,200 amperes) when welding thin material
weld nozzles are usually of the type that can cooled in air
conditioning. But, for welding require more current than , 200
amperes the nozzle weld should be cooled with water so that the
electrodes do not become overheated.OBJECTIVETo gain experience and
knowledge of the use of TIG arc-welding and materials safe.
To discipline students using workshop should.
To provide exposure to the students about security is
important.
Ensure that the students that they know how to use TIG-machine
and hand tools in the right way
Improve the students during their patience do workpiece.
Able to help students in the job environment requires skill.
SAFETY DURING WORK
Some of the measures that need to $e done while in welding
workshop areaWell-dressed, neat and safe.
Wear goggles when welding. Goggles protect the eyes when
students operate TIG welding.
Do not look at welding with the naked eye as strong arc light
can cause eye pain, glare and 1uicy.
Put the lid onto the shirt before use TIG welding.
When wearing an apron workshop always tie back not in front.
Remove watches, rings and Bracelets as they can endanger
yourself while using welding conditions and cause in1ury.
Turn off welding Before cleaning.
Always ensure TIG welding and hand tools are clean.
Make sure the door is not greasy so as to avoid injuries from
occurring.
Before getting into the workshop the students must clad
mechanical workshop.
Students who use TIG welding or equipment without the permission
of the lecturer will be disciplinary action.
In the event of any injury to the student, please report it
immediately to a lecturer in action further.
ApparatusFunction
Welding machine uses an alternating current entry (AU) and
produces direct current (DC).
used for drainage flow
EnhancerrodRod additive used to strengthen the connection with
the molten welding rod into a cauldron of molten enhancer
Regulator and Flow Meters
-Flow meter gas measure serves as a gauge for the working
pressure required.
-There are readings on the outside while the inside of the glass
tube there is a ball float that will be used to show the pressure
level of work required.
-Meterreadingswillbe taken at the center of the ball at the top
ofthe ball

BridigumCONCLUSION
From the results of this assignment I have learned many things
during this protect, especially in dealing with TIG machine. This
is because there are several steps that must be followed before
conducting proper welding TIG is. For example: adjust the gas
pressure which is suitable for welding workpiece. I also gain
experience and knowledge of the use of TIG arc-welding and
materials safe .At last also know how to use TIG-machine and hand
tools in the right way.
