2. No current display in ultrasonic test

 

Reasons: 1. The power tube is burned out; 2. The high-voltage capacitor is burned out; 3. The relay control circuit is faulty.

 

Solution: Replace related burned parts.

 

Misunderstanding of the process of welding workpieces: Ultrasonic energy is instantaneous, and the welding point should be dots or lines, and the transmission distance must be in accordance with the ultrasonic welding method. Some people think that as long as it is a plastic material, no matter how the joint surface can be welded well, this is also a misunderstanding.

3. Acoustic test current is too large and overloaded

 

Reasons: 1. The welding head is not locked or there are cracks; 2. If there is no welding head and the current is large, the transducer or the secondary rod is aging or cracked; 3. The characteristics of the power tube are changed or burned; 4. Power The amplifying circuit part is faulty.

Solution: Replace related parts.

 

It can perform spot and strip welding on thin materials of conductive metals such as copper, silver, chromium-nickel, etc. It can be widely used in thyristor chip leads, fast fuse melt sockets, electrical lead terminals, lithium ion, nickel Point and strip welding of pole pieces and tabs of hydrogen and nickel-cadmium batteries.
