摘　　要： 为了实现基于旋转电弧传感器的水下自动焊接,并获得良好的焊缝成形和较高的跟踪精度,必须确定水下焊接时的最佳焊接工艺参数。本文着重研究了水下焊接旋转电弧传感器的焊接电流、旋转频率、焊枪高度和焊枪旋转半径4个主要影响因素对焊缝成形和电流信号特征的影响。通过正交试验的方法,以水下焊接的焊缝成形和电流信号特征的好坏作为评价指标,确定了最优焊接工艺参数,为后续焊缝跟踪提供试验依据。 In order to realize the underwater auto-welding based on rotating arc sensor and get good weld forming and high accuracy tracking,it was necessary to optimize underwater welding parameters.The effect of four major factors were mainly studied which were welding current,rotating frequency,torch height and the radius of the torch on the welding forming and underwater welding current signals.Orthogonal test which used welding forming and underwater welding current signals as the index of evaluation was done to determine the optimized parameters for the follow-up seam tracking.
