Description:
The ultrasonic metal welding process is a process between cold press welding and friction welding that utilizes high density energy generated by high frequency mechanical vibration. The mechanical vibration of the welding head of the ultrasonic metal welding is parallel to the surface of the workpiece. During welding, the static pressure acts perpendicularly on the welding surface through the welding head, and at the same time superimposes the shearing force of the high-frequency vibration. When the shearing force exceeds the elastic limit of the material, the part of the contact surface of the workpiece begins to slip. This shearing force The direction is constantly changed at a frequency of tens of thousands of times per second during the welding process. Breaking and removing dirt on the surface of the workpiece, the surface of the pure metal begins to contact in multiple points. As the high-frequency vibration continues, the contact area of the pure metal expands until it expands into the entire weld zone, and at the same time, atoms are formed on the contact surface. Diffusion, metal recrystallization produces fine grain structure and exhibits cold metal deformation characteristics.

Ultrasonic metal spot welding failure analysis:
1. Fever
The welding head will have a certain amount of heat during operation, which is caused by the mechanical loss of the material itself and the heat conduction of the weldment. Whether the welding hair heat is normal or not, when the load is not loaded (ie, it does not touch the workpiece), the ultrasonic wave is continuously emitted for more than half an hour, and the temperature cannot exceed 50-70 degrees Celsius. If the heat is severe, the welding head is damaged or the material is unqualified and needs to be replaced. .
2. Howling
When there is a howling when the welding head is working, the following reasons should be analyzed:
a. Is the mounting screw loose?
b. Whether the welding head is cracked
c. Whether the welding head is in contact with objects that should not be in contact
3. Overload
When the generator issues an overload alarm, it should be checked as follows:
a. No-load test, if the working current is normal, it may be that the welding head is in contact with the object that should not be touched or the parameter adjustment between the welding head and the welding seat is faulty.
b. When the no-load test is not normal, first observe whether the welding head has cracks, whether the installation is firm, then remove the welding head and then carry out the no-load test to eliminate whether there is a problem with the transducer + horn, and eliminate it step by step. . After eliminating the possibility of failure of the transducer + horn, replace the new horn to determine.
c. Sometimes there is a situation where the no-load test is normal and not working properly. There may be changes in the inside of the original such as the welding head, resulting in poor sound energy transmission. Here is a relatively simple method of judgment: hand touch method. The working head or horn has a very uniform amplitude when working on the surface, and the hand feels velvety smooth. When the sound energy is not transmitted smoothly, there is a feeling of bubbles or burrs when touched by hand. Exclusion methods are used to eliminate problematic parts. The same situation can occur when the generator is not normal, because normally the transducer input waveform should be a smooth sine wave, which can also occur when there are spikes or abnormal waveforms on the sine wave. At this time, it can be judged by replacing another whole acoustic energy component.
