Gas Metal Arc Welding

(redirected from Gas metal)

Welding, Gas Metal Arc


a type of arc welding in which protective gases are fed to the weld zone in order to prevent air from acting on the weld. Gas shielding provides a stable arc, improves the conditions for forming a weld, and improves the quality of the weld itself.
