Method of welding high nitrogen containing stainless steel and welding material therefor

摘要

In a method of welding a high nitrogen containing stainless steel using, as a base metal, a high nitrogen stainless steel containing nitrogen at or above a solubility equilibrated with N₂ at 1 atm (1.01 x 10⁵ Pa) when melted, weld material is used having a high Cr, Mo content to maintain N in the weld metal, the resulting weld metal after the completion of welding being free from blow holes and having mechanical characteristics and corrosion resistance comparable with those of the base metal due to the maintenance of N in the weld metal.
