Information

How does the high-frequency welded pipe unit prevent damage?

Generally speaking, the formulation of high-frequency welded pipe units must comply with safe operating procedures. Operators must not be in contact with the mold during the operation of the unit, and they must pay attention to placing their hands in the direction of the pipe to avoid improper operation on their own health and safety. Make an impact.

In addition, the operator of the high-frequency welded pipe should pay attention to check whether the lubrication points of the unit are lubricated before operation, otherwise pay attention to add some lubricating oil to ensure that the unit can operate and work normally. During the use of the unit, it is necessary to pay attention to the use of some heat-resistant synthetic composite aluminum-based grease, so as to prevent the unit from being damaged.

Common problems and solutions for high frequency welding of welded pipe units

1. Weak welding, desoldering, cold stacking;

Reason: The output power and pressure are too small;

Solution: 1 adjust the power; 2 change the shape of the bevel for the thick pipe blank; 3 adjust the extrusion force

2. Ripples appear on both sides of the weld; Reason: The convergence angle is too large,

Solution: 1 Adjust the position of the guide roller; 2 Adjust the solid bending forming section; 3 Increase the welding speed

3. Welds have deep pits and pinholes;

Cause: Overheating

Solution: 1 Adjust the position of the guide roller and increase the closing angle; 2 Adjust the power; 3 Increase the welding speed

4. The weld burr is too high;

Reason: HAZ is too wide

Solution: 1 increase welding speed; 2 adjust power;

5. Slag inclusion;

Reason: The input power is too large and the welding speed is too slow

Solution: 1 adjust power; 2 increase welding speed

6. Cracks outside the weld;

Reason: the quality of the base material is not good;

Solution: 1 Guarantee material; 2 Adjust squeezing force

7. Wrong welding

Reason: Poor molding accuracy;

Solution: adjust the forming die roll of the unit; the forming speed of the welded pipe unit is restricted by the high-frequency welding speed. Generally speaking, the unit speed can be faster, reaching 100 meters per second, and the existing unit speed in the world even reaches 400 meters / second, and high-frequency welding, especially induction welding, can only be formed below 60 meters / second, and more than 10mm steel plate is formed. The forming speed of domestic unit production can actually only reach 8-12 meters / second.
