In the welding process, the arc must not be too long otherwise, it will cause unstable arc burning, large amounts of spatter, light penetration, undercut, blowholes etc. If the arc is too short, it will cause electrode sticking to the work piece. In MMA welding the arc length is usually equal to 0.5 1.0 times the diameter of the electrode.

Welding Process Comparison KTIG

Submerged Arc Welding is a process which requires a continuously fed, consumable, solid or tubular metal cored electrode. The molten weld is protected from atmospheric contamination by being submerged under a blanket of granular flux consisting typically of lime, silica, manganese oxide, calcium fluoride and other compounds.
