Gas Metal Arc Welding: An Introduction (Download PPT File)


Definitions :- 
The Gas Metal Arc Welding Process is a consumable welding process where an arc is generated between a continuously fed, solid wire electrode and the grounded base metal. Heat from the arc melts the base metal and the wire electrode allowing them to be joined into a solid piece. The molten weld puddle is protected from the atmosphere by an externally supplied shielding gas.
