摘　　要： 搭建了基于高速旋转电弧传感器的水下焊接焊枪偏差识别的实验系统。利用LabVIEW编程进行双通道采集焊接电流信号和转速数字信号,并进行小波滤波、信号合并等处理,最后采用左右区间积分方法进行焊枪偏差识别。实验结果表明,本偏差识别方法有较高的可靠性和精度。 An experimental system for underwater welding identification of welding torch offset based on high speed rotational are sensor was established. Labview was adopted to program to acquire the welding current signals and speed digital signals by two channels, then wavelet filtering and signal merging were applied to process the signals. Finally, left-right integral method was adopted to identify the welding torch offset. The experiment results indicate that the offset identification method possess good reliability and precision.
