Out-of-position automatic cored welding electrode
摘要:
Coredtype arc-welding steel electrode particularly intended for out-of-position welding wherein the ingredients in the core provide a pinch-effect type metal transfer at relatively low arc currents as well as a viscous slag which prevents the molten metal in the weld pool from being pulled out of the weld pool by the force of gravity. The ingredients making up the core provide a CaF2 metallic oxide slag system which provides a shielding action to the arc, plus as an essential ingredient(s), a compound of barium or strontium or both.
