If it is an old tooling, stick the product on the welding head first, and observe whether the gap between the product and the welding head is too large to determine whether the welding head is worn out; if it is a new tooling, please scan with the welding head. Observe his frequency, power, and graph to make sure that the welding head has no problem.
Use a caliper to check the size of the welded product, and then debug according to the difference of the data:
1. The size of the welded area is too large, and the size of other positions is OK. Please adjust the horizontal plate and raise the corresponding position. If adjusting the horizontal plate has a greater impact on other positions, you can paste thin tin foil on the tooling where the welding is not strong;
2. The overall height of the product is too large. Please modify the welding parameters and increase the welding depth. After the modification, if the defect can be eliminated, please observe whether there is any flash in other positions;
3. The size is OK, please adjust the following parameters: increase the amplitude, reduce the air pressure, and slow down the descent speed of the welding head. If the defect can be eliminated, please confirm whether there is flash in other positions;
4. The size is OK and the welding is still not strong after the above measures, or the size is too small after welding and the welding is not strong. Please contact the process and structural design to modify the height of the welding rib or make other corresponding modifications.
Recently, such a problem has been discovered. In order to get off work early, some workers adjusted the data privately, adjusted the air pressure and welding speed to unreasonable states to speed up the welding speed. If there is a manager, the data will be restored to normal. Adjusted back again, causing the product to be good and bad. Therefore, when the workshop reports that some products are leaking and some are not leaking, if the tooling and raw materials are confirmed to be OK, it can be considered that this has happened, and the workshop management personnel should be asked for assistance to prevent such incidents.Ultrasound equipment
