Effect of Roller Adjustment on Steel Tube Quality

(1) Guide roller
The role of the guide roller is to control the direction of the weld to ensure that the pipe straight does not reverse into the squeeze roller, the second is to ease the edge of the extension and rebound to determine the size of the opening angle. Adjustment is not easy to cause steel pipe seam twisting or welding, steel pipe edge waves and other defects.

(2) Squeeze rollers
The role of the squeeze roller is the edge of the heating wire welding temperature of the body under the action of the pressure to complete the welding. In the process of production, we should pay attention to the size of the opening angle of the squeeze roller. When the pressing force is small, the strength of the weld metal will decrease and the crack will be cracked. When the pressing force is large, the strength of the weld will be reduced, Resulting in welding and other welding defects.
