Ultrasonic metal welding features:
　(1), the equipment drives the metal friction, the cylinder is pressurized, the welding time is extremely short, and the welding surface does not produce the roughness of the rough surface.
　(2) The equipment is easy to realize automation, the cost of the welding head is saved by the resistance welding, the operation is convenient, and the welding speed is fast.
　(3) Welding of different metals does not require the addition of welding aids.
　(4), the deformation measurement is small, does not generate a large amount of heat, and the material is deformed.
　(5), no need to deal with the surface, such as oily surface, paint can also be welded
　(6), no external heating, uniform welding, good welding consistency, automatic alarm function.
　(7), very suitable for welding in the electronics industry, the resistivity is almost zero
Ultrasonic metal welding advantages:
　(1) High welding strength, firm and reliable, can easily adjust the width of welding forming (W) and (H)
　(2) Welding will not damage the large area of ​​the product and will not produce excessive oxide layer.
　(3) The conductivity is good after welding.
　(4) The surface of the welded metal has low requirements for cleanliness, oxidation, and electroplating are all solderable;
　(5) Short welding time, no need to add any auxiliary materials
　(6) Welding has no operational experience requirements, ordinary production workers can also operate, no technical difficulty, safety and environmental protection.
