MIG WELDING
|
TIG WELDING
|
1. This welding is known as
metal inert gas welding.
|
1. This is known as tungsten
inert gas welding.
|
2. Metal rod is used as
electrode and work piece used as another electrode.
|
2. Tungsten rod is used as
electrode.
|
3. It is gas shielded metal arc
welding.
|
3. It is gas shielded tungsten
arc welding.
|
4. Continuous feed electrode
wire is used which are fast feeding.
|
4. Welding rods are used which
are slow feeding.
|
5. The welding area is flooded
with a gas which will not combine with the metal.
|
5. Gas is used to protect the
welded area form atmosphere.
|
6. MIG can weld materials such
as mild steel, stainless steel and aluminum. A range of material thicknesses
can be welded from thin gauge sheet metal right up to heavier structural
plates.
|
6. TIG weld things like kitchen
sinks and tool boxes. Pipe welding and other heavier tasks can also be
performed, you just need to have a unit that is capable of putting out the
amount of power that you need.
|
7. MIG requires consumable
metallic electrode.
|
7. It used non
consumable tungsten electrode
|
8. Electrode is feeded continuously from a wire reel.
|
8. It does not require
electrode feed.
|
9. DC with reverse
polarity is used.
|
9. It can use both
A.C and D.C.
|
10. Filler metal is compulsory used.
|
10. Filler metal
may or may not be used.
|
11. It can weld up to 40 mm thick metal sheet.
|
11. Metal thickness
is limited about 5 mm.
|
12. MIG is comparatively faster than TIG.
|
12. TIG is a slow
welding process.
