A welding material, to be used for welding a base metal made of an austenitic alloy comprising C ‰¤ 2.0%, Si ‰¤ 4.0%, Mn: 0.01 to 3.0%, P: more than 0.03% to not more 0.3%, S ‰¤ 0.03%, Cr: 12 to 35%, Ni: 6 to 80%, sol. Al: 0.001 to 1% and N ‰¤ 0.3%, with the balance being Fe and impurities to a base metal made of another austenitic alloy, which comprises 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 not more than 70%, sol. Al: 0.001 to 1% and N ‰¤ 0.3%, with the balance being Fe and impurities can suppress the weld solidification cracking which occurs in an austenitic alloy having a high P content and showing fully austenitic solidification. Therefore, the said welding material can be widely used in such fields where a welding fabrication is required. The said welding material may contain a specific amount or amounts of one or more elements selected from Cu, Mo, W, V, Nb, Ti, Ta, Zr, Hf, Co, B, Ca, Mg and REM. |
