Principle Of Metal Inert Gas Welding. MIG Metal Inert Gas Or Gas Metal Arc Welding GMAW is a welding process in which a consumable metal electrode is used to produce the electric arc to join the metal pieces together in the environment of a shielding gas. In this process all the equipment are connected carefully.
Inert gas supply is provided around the electrode during the process. Gas metal arc welding GMAW is a high-speed economical process that is sometimes referred to as metal inert gas MIG welding. The gas cylinder and oxygen cylinder connected to the welding torch through pressure regulators.
These gases will protect the join area from oxidation and generates multiple welding material layers.
It uses a fresh metal electrode that is protected by gas like helium argon etc. MIG stands for metal inert gas welding or sometimes it is known as Gas Metal Arc welding. This arc melts the base metals. Now the regulate pressure of gas and oxygen supplied to the torch where they properly mixed.
