What is the difference between TIG & MIG welding?
The major difference between Mig and Tig welding is that one process uses a continuously feeding wire (MIG) and the other you use long welding rods and slowly feed them into the weld puddle (TIG). MIG and TIG welding both use an electric arc to make the weld.
MIG welding is a very simple and easy process to learn compared to learning how to TIG weld. The technical names for these are metal inert gas (MIG), and tungsten inert gas (TIG).
A MIG welder works by using a continuously feeding spool of welding wire that burns, melts and fuses both the base and parent metals together. You can weld a variety of 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.
TIG welding on the other hand is more commonly used for your thinner gauge materials. Items that are made with this process are things like kitchen sinks and tool boxes. The biggest benefit is that you can get your power down really low and not blow through the metal.
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.
The main difference between MIG and TIG welding is that one method uses a continuously feeding electrode and is a very fast way of putting down welds. The other way is a much more fine and delicate welding technique…
- This welding is known as metal inert gas welding.
- Metal rod is used as electrode and work piece used as another electrode.
- It is gas shielded metal arc welding.
- Continuous feed electrode wire is used which are fast feeding.
- The welding area is flooded with a gas which will not combine with the metal.
- 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.
- MIG requires consumable metallic electrode.
- Electrode is feeded continuously from a wire reel.
- DC with reverse polarity is used.
- Filler metal is compulsory used.
- It can weld up to 40 mm thick metal sheet.
- MIG is comparatively faster than TIG.
- This is known as tungsten inert gas welding.
- Tungsten rod is used as electrode.
- It is gas shielded tungsten arc welding.
- Welding rods are used which are slow feeding.
- Gas is used to protect the welded area form atmosphere.
- 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.
- It used non consumable tungsten electrode
- It does not require electrode feed.
- It can use both A.C and D.C.
- Filler metal may or may not be used.
- Metal thickness is limited about 5 mm.
- TIG is a slow welding process.
