Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tu...
The primary function of welding shielding gases is to isolate the weld pool from the atmosphere, stabilize the arc, control penetration depth, and enhance overall weld quality. Conversely, select...
The welding electrode is a metal rod that is melted and filled at the joint of the welding work-piece during gas welding or electric welding. The material of the electrode is usually the same as th...
