【 摘 要 】

Generally, magnesium alloys show interesting technological characteristics, which make them valuable for many industrial applications. Good mechanical properties, creep resistance and good castability, recyclability are only some of the most important properties remarkable for their employment in different areas. Generally, at industrial level welding technologies, like Tungsten Inert Gas technique, are used to eliminate and/or to repair the casting defects. In the present paper some details on their microstructural behaviour and mechanical performances on welded WE43 magnesium alloy are evaluated and reported. The obtained results have demonstrated that welding do not decrease the mechanical performance of the material and the heat affected zone cannot compromise the overall behaviour of the welded samples. In most of cases, the material's failure takes place nearly the welding defects.
