Man-machine collaboration shared control remote welding method

A man-machine collaboration shared control remote welding method relates to a remote welding method. The invention aims to solve the problems in the prior remote welding that the direct control operation can not be continuously carried out and particularly can not work under the situation of time delay, and an autonomous tracking weld seam can not be welded under the situations of complicated welding environment and irregular groove outline dimension of a weld seam. The remote welding method comprises the following steps: firstly, a macroscopic zooming camera acquires a two-dimensional video image, and the visual field of an operator is adjusted in a central monitoring man-machine interface; secondly, a robot guides a welding gun to reach the upper part of the weld seam; thirdly, the operator tracks the weld seam; fourthly, a workpiece is fixed on a working platform to form the welding environment at the remote end; fifthly, the robot moves towards an initial point of the weld seam; sixthly, the welding gun ensures that arc-length distance parameters of the workpiece are set by the central monitoring man-machine interface; and seventhly, the operator sets a shared control algorithm through the central monitoring man-machine interface.
