When the product cannot align the workpiece after welding, the reasons for this are:
1、 The workpiece is not aligned after assembly.
Solution:
1. Add a rib between the two pieces.
2. Design tools or positioning systems for guidance.
2、 The bottom die is not properly supported.
Solution:
1. Redesign appropriate support metallurgy and raise the bottom formwork if necessary.
2. If the bakelite is inclined, please add a hard support.
3、 The side walls are curved.
Solution:
1. The side wall of the workpiece is reinforced.
2. If the bakelite is inclined, please add a hard support.
4、 The welding line is poorly designed.
Solution:
Redesign the correct welding line.
5、 The tolerance of the workpiece is too large.
Solution:
1. The side wall of the workpiece is reinforced.
2. If the bakelite is inclined, please add a hard support.
When internal parts are damaged during product welding, the reasons for this are:
1、 The range is too large.
Solution:
Reduce the amplitude.
2、 Welding time is too long.
Solution:
1. Increase amplitude or pressure and shorten welding time.
2. Adjust the buffer pressure.
3、 The workpiece absorbs too much energy.
Solution:
1. Reduce the amplitude.
2. Reduce the pressure.
3. Shorten the welding time.
4. Use the energy controller.
4、 Parts are unsuitable, and the distance between connecting surfaces is too close.
Solution:
1. Ensure that the internal parts are properly coordinated to move the internal parts and avoid stress concentration areas or deformed crimping positions.

2. Design tools to counteract internal pressure.
