Ultrasonic metal spot welding machine ultrasonic welding is a fast, clean and economical technology, widely used in various automation industries. The ultrasonic metal welding process is a process between cold press welding and friction welding that utilizes high density energy generated by high frequency mechanical vibration. The mechanical vibration of the welding head of the ultrasonic metal welding is parallel to the surface of the workpiece. During welding, the static pressure acts perpendicularly on the welding surface through the welding head, and at the same time superimposes the shearing force of the high-frequency vibration. When the shearing force exceeds the elastic limit of the material, the part of the contact surface of the workpiece begins to slip. This shearing force In the welding process, the frequency is tens of thousands of times per second.
Ultrasound metal spot welding machine is suitable for welding the same or different metal parts with less energy. The high frequency electric energy is converted into mechanical vibration energy by transducer to act on the workpiece of ultrasonic metal spot welding machine, which produces high frequency friction between the two workpieces'surfaces until the two workpieces' surfaces are heated and fused together. Under appropriate pressure, the metal surface molecules are penetrated into each other through cold grinding and horizontal movement to achieve welding. Objective Equipment. It is an ideal equipment for single-point, multi-point, square, strip, single-layer, multi-layer and composite welding of fine and thin materials such as aluminum, nickel, copper and silver.
