摘　　要：基于等离子穿孔型弧焊(K-PAW)的焊缝成形结构特点,通过对多种不同的热源作用模式进行比较,获得了适合K-PAW焊接成形工艺的体积热源组合式作用模式。把组合式模式应用到K-PAW焊接成形热过程中的SYSWELD软件有限元数值模拟分析中,计算了不锈钢K-PAW焊接工艺中的温度场及成形焊缝的结构尺寸大小,结果表明了所采用热源模式的准确性。The volume heat source combined action mode was obtained through carrying on the comparison to different heat source mode and based on the weld structure characteristics of plasma perforation type arc welding（K-PAW）. The combined model was applied to the SYSWELD software finite element numerical simulation analysis in the process of K-PAW welding heat, the temperature field of stainless steel K-PAW welding process and the structure size of forming weld were calculated. The result show that the accuracy of the heat source model adopted in this paper.
