Description:
As the welding gun moves, a wire consisting of a consumable tubular electrode with a central flux core is fed to the metal. This arcs and generates heat that melts the base metal and electrode into a pool of molten metal. The flux disintegrates into a cloud of shield gas, which may be supplemented by additional shielding gas for welding guns with gas nozzles. Behind the movement of the welding gun, the pool solidifies into a line of weld metal. The flux that dissolves in the weld pool rises to the top and forms solidified slag on top of the solidified weld metal.
