Electrofusion welding machine is a special equipment for PE pipe electrofusion welding. It mainly supplies constant welding voltage or welding current for welding, and detects and controls the welding process, so that the welding result reaches the ideal form. Technically speaking, the electric fusion welding machine belongs to the power source range. It integrates power electronics skills, active control skills, active detection and active identification skills, computer hardware skills, software skills, display skills, barcode scanning skills, and database skills. One.
At present, most electric fusion welding machines are applied to the welding of steel mesh skeleton PE conforming pipes, and its connection methods are also very important. For example, the fusion welding method, ultrasonic vibration is transmitted to the weldment with the welding head. The resistance is large, so local high temperature is generated, and the welding interface is melted. Under a certain pressure, the two weldments can achieve a beautiful, fast and strong welding effect.
In the implantation (insertion) method, a nut or other metal is inserted into a plastic workpiece. Firstly, the ultrasonic wave is transmitted to the metal, and the high-speed vibration causes the metal object to be directly embedded in the molded plastic, and at the same time, the plastic is melted, and the embedding is completed after the solidification. The molding method uses ultrasonic waves to instantly melt and shape plastic workpieces. When the plastic is solidified, it can make metal or other plastics firm.
The resection method uses a special design method of the welding head and the base. When the plastic workpiece is just shot, it is directly pressed on the plastic branch, and the effect of resection is achieved by ultrasonic conduction. The riveting method joins metal and plastic or two plastics with different properties. The ultrasonic riveting method can be used to make the weldment not brittle, beautiful and strong.
In addition, the electric fusion welding machine can also use spot welding, using small welding heads to spot weld two large plastic products, or a row of tooth-shaped welding heads directly pressed on two plastic workpieces to achieve the point Welding effect.
