The ultrasonic metal welding machine is widely used in many fields. Its operating principle is that the metal welding transducer converts the vibration signal into mechanical energy, which is applied to the surface of the welded metal part, and the welding joint friction generates heat, which makes the molecules alternately fuse. To achieve the effect of welding. What are the factors affecting metal welding?
When welding, it is necessary to apply necessary pressure to the weldment while strictly controlling the welding time and ultrasonic power. Pressure, time and power are the three elements to ensure welding quality.
Welding pressure: The purpose of applying pressure to the weldment is to form a relatively stable welding load for the acoustic component. Due to the static pressure applied to the weldment, the material contact surface of the weldment is good, so that more ultrasonic energy can be absorbed. So as to achieve the standard effect.
Welding time: Since the output power of the welding machine is constant, the energy obtained by the weldment is proportional to the ultrasonic action time, so the selection of the welding time is the key. Welding time is short, there will be false welding, welding time is long, resulting in weldment deformation. The welding time can be determined after several tests.
The above three factors must be mastered in the welding process, so that some problems can be avoided as much as possible, the quality will be guaranteed, and the corresponding welding quality will be improved.
