Paper Title:
The Effects of He–Ar-O2 Shielded Gas Addition on GTA Welding on Welded Shape of UNS S31803 Duplex Stainless Steel
  Abstract

The effects of oxygen in helium-argon base shielded GTAW on weld shape of weld penetration are systematically investigated by bead-on-pale welding on UNS S31803 duplex stainless steel. The results show that amount of oxygen addition to He-Ar mixed shielding can significantly change the weld shape from a wide narrow type to narrow deep one and the weld depth/width ratio can be doubled due to the change in Marangoni convection condition from an outward to an inward direction.
