WELDING ADDITIVE FOR ELECTRIC ARC WELDING AND LASER BEAM WELDING OF MIXED JOINS COMPOSED OF AUSTENITIC AND FERRITIC STEEL

摘要

The present invention relates to welding additives for electric arc welding and laser beam welding of mixed joints composed of austenitic high manganese-containing steel and ferrite steel, wherein the high manganese-containing steel has a manganese content of at least 7-30% by weight. Have Here, the welding additive consists of the following alloys in weight percent: C 0.04-1.0; Mn 7-30; Si ≤ 6; Al ≤ 4; Mo ≤ 2; Ti ≤ 0.5; Zr 0.01-01; B 0.001-0.01; P 0.005; S 0.002; N 0.008; The balance of iron and the inevitable element of steel.
