Abstract
A high nitrogen flux cored wire for welding of Cr--Ni type stainless steel is formed by filling a flux into a sheath of stainless steel. The flux is composed of N and nitrogen compound (total converted value of N): 0.05 to 0.30 wt % with respect to total weight of wire, in the sheath and the flux; and TiO.sub.2 : 4.0 to 8.0 wt %, SiO.sub.2 : 0.3 to 3.0 wt %, Al.sub.2 O.sub.3 : 0.05 to 1.5 wt %, metal fluoride (converted value of F): 0.05 to 0.7 wt %, ZrO.sub.2 : less 0.5 wt %, and metal carbonate: less than or equal to 1.0 wt % with respect to total weight of the wire, in said flux.
