摘　　要：利用机器人驱动伺服焊枪进行点焊控制的同时,研究从伺服编码器中在线提取压痕深度来进行焊点质量在线评价.通过在0.8 mm、45#热镀锌钢板上的验证,表明该方法是切实可行的,并且检测成功率较高,能够代替目前常用的焊点质量离线抽样检测方法,如破坏性检测、无损检测法等.Using robot driven servo gun system to conduct spot welding process, this paper studied how to extract electrode indentation depth to on-line inspecting weld quality. This method is validated by using 0.8 ram, 45# galvanized steels. So it can be concluded that this method is feasible on production line and it can replace the off-line welding quality inspecting methods such as destructive inspection and non-destructive inspection methods.
