Welding seam tracking method in membrane wall welding process

Abstract

The invention relates to a welding seam tracking method in a membrane wall welding process. The method comprises the following steps: additionally arranging a self-adaptive welding gun adjusting device on each welding gun; collecting video information of a welding seam of a flat steel bar and an adjacent steel pipe through a laser vision sensing device at the front part of each welding gun; transmitting the video information to a vision identification server for analysis; providing the current position and angle information of the welding seam for each self-adaptive welding gun adjusting device through the vision identification server; transmitting adjustment data to a control servo drive mechanism through each self-adaptive welding gun adjusting device, so as to adjust the position of each welding gun in a real-time manner. According to the invention, the method solves the problem that the synchronous tracking of a plurality rows of welding seams is more difficult in the membrane wall welding, overcomes the interference to an image by factors such as strong arc light reflected by a surface in the welding process, can be used for obtaining clear, stable and real-time welding seam image information, and can guarantee the processing quality; the welding production efficiency is improved, the welding quality is stabilized, and moreover, the harm of an occupational disease is alleviated or eliminated as a welder can be kept far away from a harmful work environment.

Description

technical field [0001] The invention relates to a tracking detection method, in particular to a welding seam tracking method in the welding process of a membrane type water cooling wall. Background technique [0002] With the development of large-capacity and high-parameter boilers, the welding quality requirements are getting higher and higher. At the same time, in order to adapt to the changes in my country's boiler industry going to the international market and domestic human resource costs, the current welding processes and methods cannot meet the needs of development. We should continue to focus on improving welding efficiency, welding quality, reducing costs, improving the welding environment and other issues, popularize the application of new processes, and improve the level of welding automation, mechanization, and digitization. [0003] Membrane water wall tube panel is actually the main pressure part of boiler furnace wall. In order to reduce product cost, the membr...
