Abstract

The non-combustible Mg alloy is useful for structural material because of the high specific strength and the high ignition point, but the suitable welding condition was not established for manufacturing floor. In this study, a simple evaluation method for fatigue limit characteristics of welded joint was proposed, using the edge shape of welding bead geometry, the inner defect size and the material characteristics. Moreover, the welding condition ranges to ensure a stable fatigue limit for TIG butt joint of non-combustible Mg alloy were proposed by using this method.
