CHARGE FOR PRODUCING WELDING FUSED FLUX Russian patent published in 2012 - IPC B23K35/362 B23K35/40 

FIELD: chemistry.

SUBSTANCE: invention can be used in machine welding and pad welding carbon steel with low-alloyed welding wire. The charge for making welding fused flux used is gabbro-diabase rock from the Lomovsky deposit in Perm region, having the following composition, wt %: SiO₂ - 48.56, MnO - 0.22, CaO - 8.33, MgO - 3.71, Al₂O₃ - 12.44, Na₂O - 2.37, K₂O - 1.23, TiO₂ - 4.42, Fe₂O₃ - 8.55, P₂O₅ - 0.47, S_total - less than 0.03. Use of the gabbro-diabase enables to obtain high-silica non-manganiferous flux.

EFFECT: flux has high removability of slag the surface of the joint, and ensures quality joint formation and arcing stability.
