1. Working Principle
Electrofusion welding technology foundation: As an efficient method for connecting polyethylene pipes, the core of electrofusion welding technology lies in the process of converting electrical energy into thermal energy. In the 20-160MM electrofusion welding machine, this process is finely controlled. When the current passes through the special electrofusion pipe fittings, the resistance heating element inside the pipe fittings will heat up rapidly, generating enough heat to melt the material at the end of the polyethylene pipe. This melting is uniform and controllable, ensuring that a perfect fusion interface can be formed between the pipe and the fittings. As the temperature gradually increases and time passes, the molten materials will penetrate and mix with each other, and finally form a continuous and solid joint after cooling. This process requires not only precise control of current and voltage, but also strict monitoring of heating time and cooling rate to ensure that the welding quality meets the standards.

2. Machine structure and function
Control unit: The control unit of the 20-160MM electrofusion welding machine is the core of its intelligence. This unit is usually equipped with an intuitive touch screen or key interface, allowing the operator to easily set and adjust welding parameters. Various indicator lights and display screens on the interface can provide real-time feedback on the welding status, such as current temperature, remaining time, etc., so that the operator can see the welding process at a glance. In addition, the control unit is also equipped with advanced microprocessors and algorithms, which can automatically adjust the welding parameters according to the preset program to adapt to polyethylene pipes of different diameters and materials. This intelligent design not only improves welding efficiency, but also greatly reduces the difficulty of operation and human errors.

3. Automated welding process: Once the welding parameters are set and the welding program is started, the 20-160MM electric fusion welding machine will enter the automatic working state. In this process, the machine will automatically complete the steps of preheating, heating, melting and cooling. The preheating stage is to ensure that the pipe and electric fusion pipe fittings achieve uniform temperature distribution; the heating stage converts electrical energy into heat energy to melt the end of the pipe; the melting stage allows the molten materials to penetrate and mix with each other; the final cooling stage allows the fused materials to solidify under pressure to form a joint. The entire process does not require human intervention, ensuring the consistency and stability of the welding.

4. Temperature and time control: In order to ensure that the welding quality meets industry standards and requirements, the 20-160MM electric fusion welding machine is equipped with a high-precision temperature and time control system. These systems monitor the temperature changes and time progress during the welding process in real time through built-in sensors and feedback mechanisms, and automatically adjust according to preset parameters. For example, in the heating stage, if the temperature is too high or too low, the system will automatically adjust the current and voltage to maintain a constant heating rate; in the cooling stage, the cooling rate will be optimized according to the thermophysical properties of the material to ensure the strength and toughness of the joint. This precise control not only improves the reliability of welding quality but also extends the service life of the pipeline system.

5. Safety and protection
Safety function: The 20-160MM electric fusion welding machine is designed with full consideration of safety and reliability. In order to ensure the safety of operators and equipment, the machine has built-in multiple safety functions. For example, the overload protection function can automatically cut off the power supply when the current is too large to prevent equipment damage; the overheating protection function can automatically stop heating when the temperature exceeds the set threshold to prevent accidents such as fire; in addition, it is equipped with manual safety devices such as emergency stop buttons to quickly cut off the power supply in an emergency. The existence of these safety functions greatly reduces the operating risk and improves the safety of work.
Operator safety: In addition to the safety functions of the equipment itself, operators also need to pay attention to personal safety when using 20-160MM electric fusion welding machines. First, the operator should wear appropriate protective equipment such as insulating gloves, protective glasses, protective clothing, etc. to prevent electric shock and splashing. Secondly, the operator should ensure that the working area is well ventilated to avoid the accumulation of harmful gases and fumes.
