Path Planning of the Intersecting Line of Cylindrical Pipes Welded by the Welding Robot

Abstract:

In recent years, the welding of the intersecting lines of cylindrical Pipes is gradually replaced by welding robot operation from the traditional manual welding. In this paper, the generalized mathematical model of the intersecting line of cylindrical pipes is presented, and the intersecting line is developed into plane curve. Using the method of equal step lengths, the welding trajectory path points are obtained. In order to guarantee the welding precision, the value of the step length is obtained by calculation according to the permitted interpolation error value. This paper also gives a flowchart, which shows the process of obtaining the welding path points of the intersecting line. This method is convenient for programming the welding procedure, improves the working efficiency and ensures the stability and accuracy of welding at the same time. Finally, a common example of cylindrical pipes intersection is given, and the welding path points are obtained using programmable drawing software.
