Three Factors Affecting Welding Effect

The amplitude of the welding head of the ultrasonic welding machine will affect the ultrasonic energy. The greater the amplitude, the higher the vibration frequency generated on the object surface. The key to the amplitude of the welding head is the transducer and horn, which are determined by the manufacturer of the ultrasound welding machine. The transducer power used by the manufacturer and the structural design of the horn will affect the amplitude of the welding head. Once these are set, the welding performance of the ultrasonic plastic welder will be determined. Welding pressure is the second factor affecting the ultrasonic plastic welding machine. It refers to the pressure exerted by the equipment on two welded workpieces during welding. If the pressure is too high, the workpiece may be deformed, and if the pressure is too low, the welding may not be firm, so it should be properly. Welding time is the third factor affecting welding quality. The longer the welding time, the more ultrasonic energy the workpiece receives. In the actual welding process, the time should also be appropriate, not too long or too short. When people first use ultrasonic welding equipment to weld a product, they need to judge the welding power, welding time and pressure according to the melting point of the workpiece, material properties and other factors, so as to set accurate welding parameters. During the initial welding, the welding effect will be poor. It is necessary to continuously adjust the parameters of the ultrasonic plastic welding equipment according to the welding problems until the welding quality of the workpiece meets the requirements.
