Difference between MIG and TIG Welding - Mechanicaleducation.com

Difference between MIG and TIG welding:

MIG Welding:

  1. MIG welding is a process that uses a continuous wire electrode to produce the weld. The wire is fed through the welding gun and into the weld puddle, where it melts and joins with the parent metal. 
  2. MIG Welding - MIG stands for metal inert gas which generates the heat to melt wires that fuse with your metals during welding. With this welding technique, you slide the wire into a gun and release it at strategic points of the material you're working on. 
  3. MIG welding is relatively easy to learn and is popular because it produces strong consistent welds.
  4. MIG welding uses a wire feed that is supplied by a spool. The welders use a shielding gas to protect the weld from contamination. The shielding gas protects the weld from contamination, and the wire electrode provides the filler material for the weld.
  5. The MIG welding process is typically used on thinner metals, and it produces a smooth, high-quality weld.
  6. The electrode used in this type of welding depends on the parent metal.
  7. It is a highly productive process.
  8. The primary filler material for this MIG Welding is consumable wire.

TIG Welding:

  1. TIG welding is a more difficult process that uses a tungsten electrode to produce the weld. The electrode is heated by an arc of electricity, and this heat is used to melt the metals being joined together. 
  2. TIG welding requires more skill than MIG welding, but it produces extremely strong welds with low levels of distortion.
  3. TIG welding uses a tungsten electrode that is held in the hand. The welders use a non-consumable tungsten rod as the heat source. No shielding gas is used.
  4. The TIG torch is used to heat the weld area, and the filler material is added by melting it into the joint with the TIG torch.
  5. TIG welding is typically used on thicker metals, and it produces a very clean and precise weld.
  6. The electrode used in this welding is tungsten.
  7. TIG welding which uses an electric arc from a temporary carbon rod is often used for harder metals such as titanium and stainless steel to free-hand.
  8. The primary filler material for this TIG Welding is non-consumable wire.
  9. It is less productive than MIG welding.
  10. TIG Welding - Inert Gas Arc Welding differs from other gas metal arc welding processes because it does not rely on the deposition of molten metal to create the weld pool.  To run a weld using this process, a continuous thrust must be supplied by another machine while at least two manual motions are required: one external force, usually provided by an inert gas pressure regulating.
  11. TIG Welding (GTAW) - Tungsten Inert Gas is one of two arc welding processes where gas protects tungsten electrodes from oxygen until it reaches work-piece. This process is more like soldering than brazing or welding.
