.... In addition, the specimen employing 100% N2 back shielding gas with 2,000 ppmO2 was acceptable in corrosion test. It was observed that the corrosion resistance of SDSS weld joint is mainly affected by depletion of nitrogen in the surface of root bead and less affected by oxygen content levels. The nitrogen...
