      Ultrasonic metal welding machine

      Ultrasonic metal welding machine ultrasonic welding is a fast, clean and economical technology that is 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.

      Ultrasonic metal welding machine

      Ultrasound metal welding is a fast, clean and economical welding technology, which is easy to realize automatic operation.

      Ultrasonic metal welding machine

      Ultrasound metal welding is a process between cold press welding and friction welding, which utilizes high-density energy generated by high-frequency mechanical vibration. The mechanical vibration of the weld joint in ultrasonic metal welding is parallel to the workpiece surface. When welding, the static pressure acts vertically on the welding surface through the welding joint, and at the same time, the shear force of high frequency vibration is superimposed. When the shear force exceeds the elastic limit of the material, slippage occurs in parts of the contact surface of the workpiece. This shear force continuously changes direction at the frequency of tens of thousands of times per second in the welding process, and breaks up and merges. Cleaning up the dirt on the surface of workpiece, the pure metal surface begins to contact with many points. With the continuation of high frequency vibration, the contact area of pure metal expands continuously until it expands to the whole welding area. At the same time, atom diffusion occurs on the contact surface, and metal recrystallization generates fine grain structure and presents cold deformation of metal. Characteristic.
