摘　　要：以16MnR钢为实验材料,研究了焊接电流和焊接速度对构件焊接残余应力的影响.实验结果表明:焊接电流和焊接速度是影响构件焊接残余应力的两个重要因素.在实验的基础上探讨了焊接电流和焊接速度影响构件焊接残余应力的机理.The effect of two important technical parameters such as welding electric current and welding speed on the welding residual stress were investigated using the 16MnR steel as experimental materials. The mechanism of welding residual stress resulting from the welding electric current and the welding speed was discussed on the basis of the experiment.
