Drag, push or perpendicular gun techniques can be used for MIG welding overhead. But because of gravity, travel speeds must be fast enough so that the weld metal does not …
About. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an …
MIG welding aluminum requires a argon shielding gas or an argon-helium mixture. You cannot use the 75/25 Ar/CO2 shielding gas to weld aluminum. Carbon dioxide cannot be present in the shielding gas because it's a reactive gas. Even a tiny amount of carbon dioxide will devastate the aluminum and create a severely impaired joint.

Good equipment makes MIG welding easier, while poor equipment can cost you dearly in frustration and weld quality. MIG welders such as the Millermatic® 211 and Millermatic 141 are ideal for the occasional welder. If, however, you're looking for a machine with multiple welding capabilities, we recommend multiprocess welders like the ...
Calculate the welding deposit rate for Fillet welding welded with Stick welding using 1/8 inches diameter welding rod . Calculation = 13.1 x 1/8 2 x 10 x0.8 = 1.64 pounds/ hour. Where: 13.1 constant for Stainless steel, 1/8 is electrode diameter, 10 is burn off rate and 0.8 is efficiency for stick welding.
