摘要:
采用冷金属过渡技术(CMT)、冷焊、激光焊将1J50软磁合金与0Cr18Ni9奥氏体不锈钢进行焊接,研究该焊接接头组织、元素分布以及力学性能。结果表明,激光焊焊点明显小于CMT、冷焊工艺;三种焊接方法都未出现气孔、裂纹等缺陷且热影响区宽度均较小;冷焊、激光焊的焊接接头沿1J50母材-焊缝-0Cr18Ni9母材方向,Fe元素含量呈上升趋势,Ni、Cr元素交替分布,而CMT焊缝中三种元素分布均匀;三种焊接方法获得的接头显微硬度差异较大,CMT焊接接头显微硬度高于冷焊和激光焊焊接接头显微硬度,拉伸时所有试样均在焊缝处发生断裂。
Abstract:
1J50 soft magnetic alloy and 0Cr18Ni9 austenitic stainless steel were welded by cold metal transition technology (CMT), cold welding and laser welding. The microstructure, element distribution and mechanical properties of the welded joints were investigated. The results show that the welding spot of laser welding is significantly smaller than that of CMT and cold welding. There are no defects such as pores and cracks in the three welding methods, and the width of the heat affected zone is small. In the cold welding and laser welding joints, along the direction of 1J50 base metal-weld-0Cr18Ni9 base metal, the Fe element shows an upward trend and the Ni and Cr elements are alternately distributed, while the three elements are evenly distributed in the CMT weld. There is a significant difference in the microhardness of the joints obtained by the three welding methods. The microhardness of CMT weld was higher than that of cold welding and laser welding. All samples were fractured at the weld during stretching.
