[0028] In the above technical solution, during the welding process, the distance to the pipe at point 4 and the distance to the flange at point 4 are continuously measured to ensure that the pipe and flange are aligned as much as possible during welding. When the detected distance exceeds the set distance, it indicates that the deviation of the pipe and flange connection exceeds the allowable range, and the alarm is triggered. The welded pipe and flange are cooled by the heat exchange plate. At the same time, the heat exchange plate acts as an isolation barrier between the pipe 5 / butt weld flange 6 and the distance measuring instrument, which can effectively protect the distance measuring instrument.
