| Abstract: | The magnesium alloy sheets have been welded by Tungsten-arc Inert-Gas welding.The microstructure and mechanical properties of the welded joint have been investigated.The results show that fine isometric grains have been found at the welding zone and the grains became coarse at the heat affecting zone,and the tensile fracture usually happened at the heat affecting zone with coarse grains. |
