g.

MIG WELDING METHOD.

1)

MIG (Metal-Inert-Gas) welding. This process uses a DC power source, control panel, and a welding gun. The

gun feeds a consumable bare electrode at a given rate into a molten pool beneath a blanket of inert gas. When

an arc is struck, a molten pool forms at once. Move the welding gun along the joint line at a rate that shapes

the right size bead. The covering inert gas keeps air from polluting the welding zone. No flux is needed.
