The invention provides a welding control method and system, and belongs to the technical field of robot welding. The method is applied to robot control equipment, and the robot control equipment is in communication connection with a welding robot and a laser camera. The method comprises the following steps of receiving first image information sent by the laser camera; determining a first welding path of the welding robot according to the first image information; sending a backing welding instruction to the welding robot, and ensuring that the backing welding instruction is used for instructing the welding robot to perform backing welding according to the first welding path and placing a navigation magnetic strip along the first welding path in the welding process; determining a second welding path of the welding robot according to the actual distance between the navigation magnetic strip and the welding robot; sending a weld joint welding instruction to the welding robot, and ensuring that the weld joint welding instruction is used for indicating the welding robot to perform weld joint welding according to the second welding path. The method can reduce the recognition error of weld joint welding, and improve the welding quality.
Description
technical field [0001] The present application relates to the technical field of robot welding, in particular, to a welding control method and system. Background technique [0002] In the field of robot welding, in order to better realize automatic welding, it is usually necessary to identify the path of robot welding through some means, and then control the welding robot to weld along the path. [0003] At present, the welding method used is mainly laser tracking welding, that is, the welding path is determined by the laser camera, and the welding robot is controlled to weld according to the path identified by the laser camera. , the texture of the weld seam will tend to be blurred, which leads to the recognition effect of the laser camera will gradually deteriorate from bottom welding to cover welding, especially during cover welding, according to the path error identified by the laser camera will be large, which results in lower quality welds.
