... inert gas should be used to protect the weld joint or seam (back side included) to minimize oxidation and the pickup of nitrogen. Titanium-stabilized alloys appear to be more resistant to the effects of nitrogen pickup due to poor shielding than are the high-purity alloys. This is apparently due...
