| 摘 要： | 研究了1Crl8Mn8Ni5N不锈钢薄板A-TIG焊与常规TIG焊和填丝TIG焊的焊接规范和焊接接头性能．结果表明：与常规TIG焊相比，A—TIG焊焊缝宽度减小，焊缝组织中晶粒细化，焊接接头的抗拉强度显著提高，且高于母材的抗拉强度；与填丝TIG焊相比，A-TIG只需小电流且不需要填丝即可达到相同的焊接性能，同时可以降低成本，提高生产效率．

| Abstract: | The welding specification and welding joint property of the activating flux TIG welding(A-TIG welding),conventional TIG welding and filler metal TIG welding in the welding experiments of thin plates of lCrl8Mn8Ni5N stainless steel are investigated.The results show that compared with conventional TIG welding,A-TIG welding can decrease the weld width,refine the grains of the welding bead microstructure and improve the tensile strength of the welding joint;A-TIG welding only needs small welding current and no filler metal for achieving the same welding performance as filler metal TIG welding,which reduces cost and improves the production efficiency. |
