5000 Watt Ultrasonic Metal Welding Terminal With No Spark , 0.9 Mpa Air Pressure

High Power 5000w 20Khz Ultrasonic Terminal Welding with No Spark

Description: 

Ultrasonic metal spot welding machine is an advanced high-tech that converts high-frequency electric energy into a mechanical oscillation energy on a workpiece and generates high-frequency conflict between the two workpieces until the heat of the two workpieces is welded together. equipment. It can perform spot-like and strip-shaped soldering on thin materials such as copper, silver, chrome-nickel and other conductive metals. It can be widely used with thyristor chip leads, fast-fuse fuse holders, electrical lead terminals, lithium ions, and nickel. Point-like, strip-shaped soldering of poles such as hydrogen and nickel-cadmium batteries.

Ultrasonic metal spot welding failure analysis:

1. Fever

The welding head will have a certain heat phenomenon during work, 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, 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, it proves that the welding head has been damaged or the material is unqualified. replace.

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. Does the welding head have cracks?

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 abnormal, first observe whether there is crack in the welding head, whether the installation is firm, then remove the welding head and perform 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, but it cannot work normally. It may be caused by internal changes in the acoustic energy components such as the welding head, resulting in poor sound energy transmission. Here is a relatively simple judgment method: hand touch method. The normal working welding head or horn surface is very uniform when working, and the hand feels velvety smooth. When the sound energy is not smooth, the hand feels like bubbles or burrs. Exclusions are used to remove problematic parts. The same situation can occur when the generator is not normal. Normally, the transducer input waveform should be a smooth sine wave. This phenomenon can also occur when there is a spike or abnormal waveform on the sine wave. In this case, another whole acoustic energy component can be used to determine .
