The operator turns the two adjusting screws 306, and the pressure roller 301 presses down on the bend C503 and the straight pipe B502. The operator then uses a welding torch to spot weld the bend C503 and the straight pipe B502 together. Since the rollers 2 and the pressure roller 301 are ball bearings, the straight pipe B502 can rotate 360° to achieve a full circle of welding between the bend C503 and the straight pipe B502. After welding, the operator turns the two adjusting screws 306 in the opposite direction to remove the welded S-shaped hydraulic pipe 5.
