摘要

以321不锈钢作为研究对象,进行了A-TIG焊的研究。先对单一组元活性剂对焊缝熔深的影响进行研究,然后根据此研究结果进行多组元活性剂摸索试验,得出最佳活性剂焊接配方,并研究其焊接接头的力学性能。试验结果表明,用最佳活性剂焊接的不锈钢321A-TIG接头力学性能良好。
        Taking 321 stainless steel as the research object, and the study of A-TIG welding was carried out. Firstly, the effect of single component active flux on the weld penetration was studied, and then the multi-component active flux was tested according to the results. Then the optimum active flux welding formula was obtained, and the mechanical properties of the welded joint were studied. The test result shows that the A-TIG welded joint of 321 stainless steel with the best active agent has good mechanical properties.
