Fault 1: uneven welding and workpiece deformation.
Solution:
1, check whether the workpiece sizes are different.
2, check whether the operating conditions cause work deformation.
3. Adjust the buffering speed or pressure.
Fault two, the base support is unstable.
Solution:
1, and raise the support point where necessary.
2. The base is redesigned.
Step 3 replace it with a hard base
4. If bakelite inclines in a large area, it needs reinforcement.
Fault 3: The contact surface of welding head, base and workpiece is uneven.
Solution:
1, the energy conservation point is redesigned to make the height uniform.
2. Adjust the horizontal screw.
3. Check whether the artificial conditions are true.
4. Check the shape and size of the workpiece.
5, lateral bending, workpiece and ribs.
6, modify the melting tool, to avoid the workpiece bending outward.
Fault 4, the workpiece error is too large.
Solution:
1. Tighten the tolerance of the workpiece.
2. Modify the size of the workpiece.
3. Check the operating conditions (pressure, delay time, welding time, curing time, etc. ).
Fault 5. Uneven welding and improper alignment of workpieces.
Solution:
1. Check whether the workpiece is offset during welding.
2. When viewing the assembly, are the workpieces aligned?
3. Check the parallelism of welding head, workpiece and melting tool.
Fault 6. The joint surface lacks close contact.
Solution:
1, check the workpiece size.
2. Check the tolerance of the workpiece.
3. Check the thimble position of the joint surface.
4. Check the alignment of the workpiece assembly.
5. Check whether the workpiece is sunken.
6. Check the cooperation between the workpiece and the welding head.
7. Check whether the support of smelting tools is appropriate.
Fault 7. Ultrasonic welding results are inconsistent.
(A) the proportion of additives is too high
Solution:
1, reduce additives.
2. Check the operating conditions.
3. Change the type of additives, that is, replace the short-line cone with the long-line cone.
Uneven distribution of additives
Solution:
1, check the operating conditions.
2, check the mold design
Poor material quality
Check operating conditions
(d) Poor cooperation of workpieces.
Solution:
1, check the workpiece size.
2, check the workpiece tolerance
3, check the operating conditions
