摘要
Abstract
Pipe weld tracking refers to the process of the welding torch automatically adjusting the trajecto-ry of the welding torch according to the changes in the pipe weld.How to adapt to different welding grooves to accurately track the weld seam and improve the welding quality is a major difficulty in pipe welding.At present,the welding seam tracking methods mainly include laser and arc tracking methods,which are either expensive or ineffective.Therefore,a tracking algorithm based on visual and arc fusion is proposed to reduce the application cost and improve the tracking effect.The improvement scheme of"modeling first,welding later"is adopted to improve the welding quality without increasing the difficulty.The implementation method is to first set the weld teach-in point and the welding start point,and calculate the slope,depth and width of the upper and lower groove of the weld groove through visual images from the welding starting point.When encountering a teach-in point,the researchers can obtain the arc informa-tion of the teach-in point.Finally,according to the multi-data fusion analysis of visual image information,welding torch trajectory,inclination angle,arc information of teach-in point,etc.,a digital model for track-ing the weld can be established.关键词
