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.

This study proposes a novel method of optimal path planning in stochastic constraint network scenarios. We present a dynamic stochastic grid network model containing semienclosed narrow and long constraint information according to the unstructured environment of an underground or mine tunnel. This novel environment modeling (stochastic constraint grid network) computes the most likely global path in terms of a defined minimum traffic cost for a roadheader in such unstructured environments. Designing high-dimensional constraint vector and traffic cost in nodes and arcs based on two- and three-dimensional terrain elevation data in a grid network, this study considers the walking and space constraints of a roadheader to construct the network topology for the traffic cost value weights. The improved algorithm of variation self-adapting particle swarm optimization is proposed to optimize the regional path. The experimental results both in the simulation and in the actual test model settings illustrate the performance of the described approach, where a hybrid, centralized-distributed modeling method with path planning capabilities is used.
