[0002] In beam and tube plate welded structural parts, there are a large number of fillet welds that need to be welded. Due to structural and process limitations, most of these parts to be welded have large deformation before welding and difficult seam alignment. We must use a seam tracking device To eliminate the welding process error, the existing electric seam tracking device needs to use a sensor to pick up the trajectory signal through the trajectory tracking sensor, and realize the trajectory deviation tracking correction through the controller to control the motor to meet the requirements of tracking welding. The application of sensor automatic control and high-precision mechanical rotation technology is highly specialized, so the application range of this technology is limited, the manufacturing and maintenance costs are also high, and it is susceptible to arc interference; while the traditional mechanical seam tracking device is flexible. Poor, low reliability, straightness deviation needs to be manually adjusted, each welding process needs to be manually moved back and forth for alignment, and the welding track needs to be manually tracked and adjusted continuously, which requires high technical requirements for personnel operation and low efficiency. Well adapted to the process requirements of welding
