A welding material for use in welding a base material made of an austenitic alloy containing C=2.0%, Si=4.0%, Mn:0.01 to 3.0%, P: more than 0.03% to 0.3%, S=0.03%, Cr: 12 to 35%, Ni: 6 to 80%, sol. Al: 0.001 to 5% and N=0.3% with the balance consisting of Fe and impurities to a base material made of another austenitic alloy, which contains C: more than 0.3% to 3.0%, Si=4.0%, Mn=3.0%, P=0.03%, S=0.03%, Cr: more than 22% to 55%, Ni: more than 30% to 70%, sol. Al: 0.001 to 1%, and N=0.3% with the balance consisting of Fe and impurities. The welding material can protect austenitic alloys which have high P contents and cause fully austenitic solidification from weld solidification cracking, thus being widely applicable to fields necessitating welding. The welding material may further contain one or more elements selected from among Cu, Mo, W, V, Nb, Ti, Ta, Zr, Hf, Co, B, Ca, Mg, and REM in specific amounts. |
