| Abstract: | The microstructure, properties and impact fracture toughness of welded joints of Ti and Ti alloy by using tungsten-argon arc welding were studied. The microstructure of weld zone changed into lamella and needle microstructure, the strength of welded joints could reach the strength level of base material. The plasticity and toughness was also higher,the rupture feature was mainly plastic.$$$$ |
