| 摘 要： | 使用CMT(Cold Metal Transfer,冷金属过渡焊接技术)焊接方法对2 mm厚度的X2CrNiN18-7不锈钢焊接过程中间隙和错边的适应性进行研究。在板厚2 mm的情况下,CMT焊接对焊缝间隙容忍力强,达到母材厚度的37.5%;磨平处理的焊缝抗拉强度可达到母材的80%~88%;对焊缝错边量容忍力可达到母材厚度的40%。

| Abstract: | 2 mm thickness X2CrNiN18-7stainless steel was welded to study the adaptability to the gap and unfitness using CMT (Cold Metal Transfer) and the results were also evaluated quantitatively.The gap tolerance of CMT welding to the weld reached 37.5％ of the base metal thickness and the tensile strength of weld was up to 80％～88％ of the parent material after smoothly processing.In addition,the gap tolerance of weld achieved 40％ of the base metal thickness. |
