Abstract

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