High-frequency induction welding machine for welding new energy automobile parts is a kind of equipment that uses electromagnetic induction principle to weld. The following is an introduction about it:

principle of operation

The work of high frequency induction welding machine is based on electromagnetic induction, eddy current and Joule's law. When the high frequency current passes through the induction coil of the welding machine, an alternating magnetic field will be generated around it. When new energy automobile parts (metal materials) are placed in this magnetic field, eddy currents will be generated inside the parts due to electromagnetic induction. According to Joule's law, eddy current generates heat under the action of the metal's own resistance, so that the welding parts of the fittings quickly heat up to reach the temperature required for welding, and then the solder is melted and filled in the welding joint to complete the welding process, and a firm welding connection is formed after cooling.

characteristic

Fast heating speed: it can heat the welding parts of fittings to a suitable temperature in a short time, which can greatly improve the welding efficiency compared with traditional welding methods. For example, it may take half a minute or even longer to weld a copper pipe joint with a conventional size, while the high-frequency induction welding machine may only take more than ten seconds.

Small regional influence: heat can be highly concentrated in the area near the welding point, which has little thermal influence on other surrounding parts that do not need to be welded and nearby objects, and can well ensure the integrity and original performance of the whole fitting structure and surrounding environment.

High welding quality: By precisely adjusting the parameters such as frequency and power of high-frequency current to control the heating temperature and time, the ideal and consistent temperature conditions can be accurately ensured at the welding parts of the fittings every time, so that the solder can be melted evenly, the quality of the welded joint is more stable and reliable, and the overall quality and consistency of the welded products are improved.

Good safety: welding is carried out by converting electric energy into electromagnetic energy and then generating heat, and there is no safety risk related to combustible gas. As long as the electricity is safe, the operation process is relatively safer and more reliable.

High operation convenience: the structure is relatively compact, easy to carry and operate, and it can be used only by connecting the power supply, and it is not limited by factors such as site space and ventilation conditions, and can adapt to various working environments more flexibly.

Automatic integration: it can be integrated with automatic production line to realize automatic feeding, welding, blanking and other processes, reduce manual operation links, reduce labor intensity and improve the stability and reliability of production line.
