Electric fusion welding machine is a special equipment for PE pipe electric fusion welding. It mainly supplies constant welding voltage or welding current for welding, and detects and controls the welding process to make the welding result reach the ideal shape. Technically speaking, the electric welding machine belongs to the power supply 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 electrofusion welding machines are used in the welding of steel mesh skeleton PE pipes. Its connection method is also very important. For example, the welding method. Ultrasonic vibration is transmitted to the weldment along with the welding head. The resistance is large, so local high temperature is generated, which melts the interface of the weldment. Under a certain pressure, the two weldments can achieve a beautiful, fast and firm welding effect.

In the implantation (insertion) method, nuts or other metals are to be inserted into the plastic workpiece. First, the ultrasonic wave is transmitted to the metal, and the metal object is directly embedded in the molded plastic through high-speed vibration. At the same time, the plastic is melted, and the embedding is completed after solidification. The molding method uses ultrasonic waves to instantly melt and shape the plastic workpiece. When the plastic solidifies, the metal or other materials of the plastic can be firm.

The cutting method uses the special design method of the welding head and the base. When the plastic workpiece is just injected, it is directly pressed on the plastic branch, and the effect of cutting is achieved through ultrasonic transmission. The riveting method is to join metal and plastic or two pieces of plastic with different properties. The ultrasonic riveting method can be used to make the weldment not easy to be brittle, beautiful and strong.

In addition, the electrofusion welding machine can also use the spot welding method, using small welding heads to weld two large plastic products at different points, or the entire row of tooth-shaped welding heads can be directly pressed on the two plastic workpieces to achieve a point The effect of welding.
