Introduction of ultrasonic metal welding machine
Principle of ultrasonic metal welding machine:
Ultrasonic metal welding machine is a special method that uses mechanical vibration energy of ultrasonic frequency to connect the same or dissimilar metals. When metal is ultrasonically welded, neither electric current nor high temperature heat source is applied to the workpiece, but under static pressure, the mechanical energy is transformed into internal energy, deformation energy and limited temperature rise. Solid phase welding occurs when the two base materials reach the recrystallization temperature. Therefore, it effectively overcomes the spatter and oxidation caused by resistance welding.
Scope of application of ultrasonic metal welding machine:
Ultrasonic metal welding machine can perform single-point welding, multi-point welding and short strip welding on thin wire or sheet materials of non-ferrous metals such as copper, silver, aluminum, and nickel.
Application fields of ultrasonic metal welding machine:
It can be widely used in the welding of SCR leads, fuse pieces, electrical leads, lithium battery pole pieces, and tabs. Ultrasonic connection technology is widely used in the field of battery production to ensure the best electrical conductivity, even when connecting different types Metal is also excellent in performance.
Features of ultrasonic metal welding machine:
The characteristics of ultrasonic metal welding process (firm and reliable, very economical), ultrasonic metal welding has the advantages of firm solder joints, low solder joint internal resistance, no oxidation marks, and beautiful appearance; no sparks are generated during welding, and the operator is safe and assured. Smoke smell, will not cause air pollution; all welding workpieces can be welded without pre-treatment, no solder, welding oil and other additives, economical and convenient; welding time is very short, generally within 0.01-1s seconds to complete the welding instantly; The temperature does not exceed its annealing temperature, so it does not change the metallographic structure of the weldment, its welding strength is stronger than other welding methods, and the welding interface is neat and clean.
Another name for ultrasonic metal welding machine:
Ultrasonic harness welding machine is a derivative equipment of ultrasonic metal welding machine. Mainly used in the welding of copper wire and aluminum wire such as automobile wiring harness and motorcycle wiring harness. So it is often called automobile wire harness welding machine.
Advantages of ultrasonic metal welding machine:
One of the most important advantages of ultrasonic metal welding is the lower temperature. The generation of temperature is inevitable, it is only caused by friction, which is only 1/3 or 1/2 of the melting point of the metal. At the low temperature generated by the welding process, the metal wire retains its original performance due to annealing and the low temperature does not damage the insulation of the wire; in addition, the lower temperature also means that thin metal can be welded to thick metal Without causing damage to thin metal. These are very important in wire harness production.
