| Abstract: | In this paper, the all position activating TIG welding （A-TIG） on Ф57 mm× 5 mm tube of 20 steel was carried out. And then the welding joints were inspection by X-ray and the mechanical properties were test. The results show that the quality of the joints can meet standard requirement very well. The microstructure of A-TIG welding joints was better than TIG welding. A-TIG has a great industry meaning for welding assemblage and efficiency increasing and costs decreasing of the steel tube. |
