Miller - Guidelines For Gas Metal Arc Welding (GMAW).pdf

July 11, 2008 · Filed Under Mechanical & Industrial Engineering  · Tags: , , ,

Gas Metal Arc Welding (GMAW) is a welding process which joins metals by heating the metals to their melting point with an electric arc. The arc is between a continuous, consumable electrode wire and the metal being welded. The arc is shielded from contaminants in the atmosphere by a shielding gas.
