| 摘 要： | 应用正交试验法对奥氏体不锈钢TIG焊用活性剂配方进行了试验研究.采用所研制的活性剂,在不开坡口的情况下,当热输入E=1.01kJ/mm时,可一次焊透5 mm厚奥氏体不锈钢板;当E=1.95 kJ/mm时,可一次焊透8 mm厚奥氏体不锈钢板,焊接过程中电弧稳定,焊缝成形良好.活性剂对焊接过程中合金元素的烧损有一定的抑制作用,所得焊缝中Cr、Ni元素的含量与母材的相比只略有下降.A-TIG焊缝的显微组织结构与TIG焊缝的相比几乎没有差别,但前者的硬度高于后者.

| Abstract: | Active flux for austenitic stainless steel TIG(tungsten inert-gas) welding was studied using the orthogonal method. With the resulting flux and heat input of 1.01 kJ/mm ,the austenitic stainless steel of 5 mm thickness was penetrated by TIG welding without beveling.When increasing heat input to 1.95 kJ/mm, the steel of 8mm thickness was penetrated. The arc was steady during welding,and appearance of weld is good. The flux has a function of suppressing alloy elements to escape from weld pool, so that the weight percentages of Cr and Ni in the A-TIG(active-tungsten inert-gas welding) weld metal are descended very slightly. The microstructure of the A-TIG welds is almost the same as that of the TIG welds. The hardness of the former is somewhate higher than that of the later. |
