Abstract

PURPOSE:The above mentioned flux, composed of a fixed composition containing more than one kind of CaF2, BaF2, NaF, AlF3, MgF2 and Al or Al and Si as deoxidizer, decreasing oxygen in welding metal, improving mechanical property and preventing defect generation. CONSTITUTION:The above mentioned flux is contained 20 - 80% of total quantity of more than one kind of CaF2, BaF2, NgF, AlF3 and MaF2 against total quantity of the flux and Al or both Al and Si as deoxidizer, within the limits of 2,5% <=Al+0.5Si<=5.5%, Si<=4%. The above flux is used combining with welding wire composed of Ni base alloy and containing quantity of oxygen in welding metal is remarkably decreased and also, welding metal having superior mechanical property and no inner defect, is formed.
