Ultrasonic metal welding uses high frequency vibration wave to transfer to the surface of two metal workpieces to be welded. Under the condition of pressure, the two metal workpieces surfaces rub against each other to form fusion between molecular layers. Its advantage is fast, energy saving,high fusion strength, high conductivity, no spark, close to cold processing.
Ultrasonic Metal Welding Advantages:
1) Welding material is not melted, not fragile metal characteristics ;
2) Good electrical conductivity after welding, very low or near zero resistivity ;
3) Low requirements on the surface of the welding metal, tin plating or metal oxide can be welded, without pre-cleaning;
4) Short welding time, without any flux gas solder;
5) Welding without spark, environmental protection and safe.
