摘　　要：为更有效地控制弹簧钢电阻点焊接头随机回火热处理过程,以提高弹簧钢电阻点焊接头质量,建立有限元数值模型,对弹簧钢电阻点焊接头随机回火热处理过程进行数值模拟分析.对比分析了弹簧钢电阻点焊接头随机多电流脉冲回火热处理过程及传统的随机单脉冲回火热处理过程.结果表明,采用多脉冲回火热处理方式比采用单脉冲回火热处理方式更容易精确控制随机热处理能量输入,更有效地控制点焊接头回火热处理温度及温度场分布,使弹簧钢电阻点焊接头获得更充分及更均匀的回火热处理.The multi-pulse tempering process of spring steel joints in resistance spot welding was simulated by finite element numerical model to control the random tempering process effectively and improve the welding quality. The results show that the energy input can be controlled accurately when using multi-pulse tempering, and the tempering temperature and temperature field distribution are also controlled effectively. The spot weld of spring steel can be tempered fully and equably by multi-pulse tempering.
