Saurashtra Chemicals Maintenance Engineer Interview Questions and Answers

GMAW stands for Gas Metal Arc Welding, a welding process that uses a continuous solid wire electrode and shielding gas to create a weld.

• Uses a continuous solid wire electrode

• Requires a shielding gas to protect the weld from atmospheric contamination

• Commonly used in industries like automotive, construction, and manufacturing

MIG stands for Metal Inert Gas welding, while MAG stands for Metal Active Gas welding. The main difference lies in the type of shielding gas used.

• MIG welding uses inert gases like argon or helium to shield the weld pool from atmospheric contamination, while MAG welding uses active gases like carbon dioxide or a mixture of gases.

• MIG welding is typically used for non-ferrous metals like aluminum, while MAG welding is mor...read more
