what is mig welding used for in engineering
For MIG welding or Flux-Cored welding, semiautomatic wire feeders are connected to a welding power source and are used to feed a spool of wire through the welding gun.
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).
