There is no need for flux and external heating, no deformation due to heating, no residual stress, and the requirements for pre welding treatment of weldment surface are not high. Not only the same kind of metal, but also the dissimilar metal can be welded. Thin sheets or filaments can be welded to thick plates. The energy of ultrasonic welding is much less than that of current welding. It is often used to weld the leads of transistors or integrated circuits. When it is used for seal welding of drugs and explosive materials, it can avoid the contamination of drugs due to dissolved objects in general welding, and it will not explode due to heating, etc.

characteristic:           
1. The ultrasonic spot welding machine adopts original transducer, stable output, high-quality component assembly, reliable performance, smart design and convenient operation. It is mainly suitable for the design of N95 mask (cup mask, dust mask, duck mouth mask, plane mask, etc.) ear band spot welding, with high production efficiency, simple operation, stable quality, etc;           
2. The design of double guide pillars can solve the problem of back tilt during welding;           
3. The operation is simple, the solder joint is firm and beautiful after welding, without damaging the material itself.
