The process of laser welding leaves rough welds at the welding position. In order to make the surface of the circular pipe more beautiful and make the weld strength and sealing performance stronger, it is usually necessary to use a roll seam device to roll the welds. The current pressure welding joint machine is usually a single-station manual operation. This single-station manual pressure welding joint machine can only operate one circular pipe at a time. The worker needs to install each cut circular pipe on the welding joint machine first, and then manually unload, replace and process the next circular pipe after the pressure welding. During this replacement process, the equipment is idle, the production process is not continuous, the overall production efficiency is greatly reduced, the manual operation speed is relatively slow, the speed of workers with different proficiency is affected by the physical condition, it is difficult to achieve efficient and stable production rhythm, and because the operation relies on manual operation, the technical level, operation habit and work responsibility of different workers are different, which makes it difficult to ensure the consistency of the pressure welding quality. Manual operation is difficult to be accurate and stable, and quality problems such as loose, uneven, porosity or virtual welding of the welds are easy to occur, which affects the overall quality and service life of the heat preservation cup.
