A-41 Studies on Stainless Steel Piping With High Durability : Part 6 Examination about the possibility of the site welding of stainless piping

Abstract

We built the stainless steel plumbing of approximately 40m and welded it while pouring back shielding gas into the piping. Then we inspected it whether a weld could get white skin and evaluated coloration parts of an oxidation scale formed on the weld by the color difference. In addition, we suggest the construction points of the automatic welding in sites.
