STRAIGHT POLARITY MAG-WELDING WIRE AND STRAIGHT POLARITY MAG-WELDING METHOD USING SAME

WIPO Patent Application WO/2023/149239

A1

Provided is a technology which is for straight polarity MAG-welding and by which not only occurrence of sputtering is reduced but also an excellent bead shape is obtained when performing MAG-welding. This welding wire is to be used for straight polarity MAG-welding, has a compositional makeup comprising, in mass%, 0.020-0.080% of C, 0.50-0.97% of Si, 1.50-2.00% of Mn, 0.001-0.050% of P, 0.001-0.025% of S, 0.10-0.30% of Ti, 0.010-0.050% of Al, 0.05-0.20% of Cr, 0.01-0.10% of Ni, 0.05-0.30% of Mo, not more than 0.0016% of Ca, 0.020-0.055% of REM, 0.0005-0.0030% of B, and not more than 0.0100% of N, the remaining portion being Fe and unavoidable impurities, and, as necessary, contains at least one selected from not more than 0.050% of Nb, not more than 0.050% of V, not more than 0.300% of Zr, and not more than 0.0150% of K.
