Ultrasonic welding strength is closely related to the quality of our welding products. During the welding process, the quality of the products welded out under different strength conditions is uneven, and the following phenomena occur when ultrasonic welding is used, and different reasons should be adjusted according to different ways of welding data.
Ultrasonic welding machine
First, when the product welding is too fusion, the cause may be: too much input energy. In this case, it can be adjusted in the following ways: 1. Reduce the use of pressure. 2. Shorten welding time. 3. Reduce the number of range segments. 4. Reduce the drop speed of the welding head.
Second, when the product welding is insufficient, the cause may be: the input energy is too little to work. In this case, it can be adjusted in the following ways: 1. Increase the use of pressure. 2. Increase welding time. 3. Increase the number of range segments. 4. Use a more powerful model. 5. Replace the mold.
Third, when the product welding is uneven, the product should be adjusted according to different ways when there are different problems: 1, when the workpiece is deformed. Solution: Check whether the workpiece size is qualified. Check whether working conditions cause deformation of the workpiece. Adjust the speed or pressure of the buffer. 2. The contact between the welding head, the bottom die and the workpiece is uneven. Solution: The welding line was redesigned to make the height consistent. Adjust the horizontal screws. Check that the operating conditions are correct. Check the shape and size of the workpiece.
3, the product side bending. Solution: Add reinforcement on the workpiece. Modify the mold to prevent the workpiece from bending outward. 4, the bottom mold support is not strong solution: if necessary, improve the support point. Redesign the bottom mold. Change to a hard base mold. If large areas of plywood are tilted, they must be reinforced.

7. Poor contact of the joint surface. Solution: Check the workpiece size. Check workpiece tolerances. Check the position of the sleeve on the surface of the joint. Check that the upper and lower workpieces are aligned. Check that the workpiece is not concave and in uneven contact with the welding head. 8. Uneven contact of welding head. Solution: Check the fit between the workpiece and the welding head. Check that the support of the mold is suitable. The above is the first half of the ultrasonic welding strength analysis and problem solving method.
The use of ultrasonic welding machine should pay attention to adjusting the welding strength, in order to achieve the ideal welding effect.
