| Abstract: | The welded joints of Dissimilar steel of 35CrMoA+S275NL are made by TIG automatic welding process in different welding process conditions.According to the specimens of welded joints involved,the analyses of the weld metal and the heat-affected zone metal are made,and the micro-hardness survey of whole welded joints is conducted.The results show that good quality weld joints can be obtained in different welding process conditions.When welding current is 100 A,preheated temperature before welding is 150 ℃,the microstructure and property of welded joints is better than others. |
