1. Welding quality analysis

(1) The cutting or welding is not firm
1. The welding pressure is inappropriate.
2 The amplitude is inappropriate.
3. The welding method is inappropriate.
4. The energy is inappropriate.
5. Limiting problem, the gap between the upper welding head and the lower sonotrode is inappropriate.
6. The pattern of the upper welding head and the bottom mold of the lower sonotrode is inappropriate.
7. The upper welding head and the bottom die of the lower sonotrode are worn too much.
8. The surface of the upper welding head and the bottom mold of the lower sonotrode is seriously polluted.

(2) The workpiece is glued to the upper welding head or lower sonotrode bottom mold
1. The pattern of the upper welding head and the bottom mold of the lower sonotrode is worn.
2. The surface of the upper welding head and the bottom mold of the lower sonotrode is seriously polluted.
3. Too much pressure to adjust the parameters.
4. If the bottom mold is stuck after changing to a new mold, please use no-load ultrasound to instantaneously touch the bottom mold 5-6 times, then put on the hard nickel sheet and then touch the nickel sheet 5-6 times with no-load ultrasonic. Remove the initial burrs on the bottom mold surface, which can reduce the bottom mold sticking phenomenon.

(3) Low welding strength
1. Part of the workpiece is cut off or falls off.
2. The welding method is incorrect and the tool head size is incorrect. To
3. Energy cannot be effectively transferred to the welding part (check screws and vibration system).
4. Too much oil and oxide film on the surface of the workpiece.
5. The welding head stroke is too short, check the limit mechanism.
6. Excessive wear of tool head.
