摘要

Provided is a method for producing a TIG welded stainless steel tube that makes it possible to curb the occurrence of welding flaws without the need to mix H2 into a shielding gas. In the method for producing a TIG welded stainless tube, a welded stainless steel tube is produced by bending a stainless steel strip in the width direction, butting two edges together, and subjecting the same to TIG welding, and a pulse waveform having a pulse frequency of 40 to 300 Hz is used as a current waveform in a welding power source.
