[0002] Galvanized welded pipe is a galvanized steel pipe made by rolling strips of steel into a tube and then welding them. Due to its production characteristics, in the production process of this type of steel pipe, additional devices are required to keep the steel sheets in a tubular shape during the welding process.

[0003] A Chinese patent with the authorization publication number CN219504059U discloses a high-frequency welding device for steel pipes, which uses two fixing rings to keep the steel sheet in a tubular shape. However, because the vertical welds of the steel sheet need to be welded and the length of the steel sheet is often long, the steel sheet needs to be continuously advanced. The distance that the fixing ring can limit the steel sheet is limited, so the second half of the steel sheet cannot maintain a tubular shape, but is constantly restricted from winding during the advancement process. This causes the edge of the steel sheet to be susceptible to resistance from the fixing ring, and friction between the two increases the difficulty of advancement, while causing scratches and damage to each other, affecting the processing efficiency and quality of the steel pipe.
