Description

technical field

[0001] The invention relates to a welding process control system and a control method of a double-layer coiled welded pipe, and belongs to the technical field of welded pipe welding technology and its control method. Background technique

[0002] Double-layer welded pipe is widely used in automobiles, household appliances and other fields. In the 1990s, my country began to introduce double-layer welded pipe production lines from abroad, which improved product quality. However, due to the high price of imported equipment and high maintenance costs, domestic must Most manufacturers still rely on the experience of the operator to control the main process parameters of the welding process, it is difficult to optimize the process parameters, and it is difficult to guarantee the welding quality of the welded pipe. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a welding process control system and contro...
