Abstract:
A continuous welding electrode comprising,a continuous metal core having an outer coating of a welding flux material, a plurality of circumscribing gaps formed at regular intervals over the entire length of said electrode, said gaps exposing a circular surface of said metal core adaptable for applying welding current to said electrode for short circuit welding operation, said welding flux material and said metal core having melting temperatures and unit weights in the following relationships: K2=(0.8 to 0.9)K1 and G2=(0.37 to 0.48)G1 wherein K1 is the melting temperature of the metal core; K2 is the melting temperature of the flux material coating; G1 is the unit weight of the metal core; and G2 is the unit weight of the flux material coating.
