ABSTRACT:
This invention relates to a welding material for welding a high-Si austenite stainless steel, capable of ensuring a high corrosion resistance of the weld metal in hot nitric acid of high concentration, while maintaining a toughness of the weld metal not smaller than 2 Kg-m/cm.sup.2, and the method of application therefor. The welding material has a composition containing not greater than 0.015% of C, 5 to 7% of Si, not greater than 2% of Mn, 15 to 20% of Cr, 10 to 22% of Ni, not greater than 0.02% of N, not greater than 0.45% of one or both of Nb and Ta, and the balance substantially Fe and inevitable impurities the sum of C and N contents is selected to be not greater than 0.03% and the sum of Nb and Ta contents is selected to be not smaller than 15.times.(C+N)%. The Ni-balance value given by the following formula ranges between -4 and -2.
