摘　　要：船舶制造中,由于船舱底部排水孔的存在,形成不连续焊缝,影响了焊接速度。为了提取排水孔特征点信号,通过对旋转电弧传感器提取焊接电流信号和激光传感器提取焊缝图像信息进行实验研究,结果表明2种传感器满足要求。最终选用旋转电弧传感器检测排水孔起始位置,视觉传感器控制机器人位姿与检测排水孔终点位置。Some drainage holes at the bottom of hall in shipbuilding form discontinuity welding seams, which directly influence welding speed. In order to extract the characteristic signal of drainage holes, the welding current signal is extracted by the rotating arc sensor ,the image of the welding seam information is extracted by the laser sensor. The experimental results show that the two sensors can meet the demand. The startpoint of the drainage holes were detected by the the rotating arc sensor and the endpoint by the vision sensor which controlled the pose of the robot simultaneously.
