In resistance welding, transistor-type high-frequency power supplies are mainly used to provide a stable DC voltage. This voltage is cleaved into a DC square wave with a frequency of 100kHz, and converted into a low-voltage DC square wave suitable for welding loads through the voltage transformation of the welding transformer. This design allows the current size and welding time during the welding process to be precisely controlled, thus improving the quality and efficiency of welding.
As you know, resistance welding is a method in which an electric current passes the heat generated by two metal surfaces in contact to bring it to a state of melting or plastic deformation, and then realizes the connection under pressure. In this process, the stability and control accuracy of the power supply are crucial to the quality of the weld. In recent years, with the development of power electronics technology, transistor-type high-frequency power supplies have been widely used in resistance welding.
So, what are the advantages of transistor-type high-frequency power supply in resistance welding?It is mainly reflected in good stability, high control accuracy, energy saving and environmental protection, easy maintenance, etc. The transistor-type high-frequency power supply uses advanced control technology and filtering circuitry to make the output voltage and current very stable. This is very important for resistance welding, as stable voltage and current ensure the stability and consistency of the weld quality.
Transistor-based high-frequency power supplies enable precise control of current magnitude and soldering time. This high-precision control ensures that the heat input and pressure action during the welding process are precisely matched, improving the quality and efficiency of the weld. For example, the Huandian transistor high-frequency power supply is a high-precision welding power supply, with 6 control modes, 5 working frequencies to choose from (1khz 2khz 3khz 4khz 5khz), servo motor control function, to achieve accurate adjustment of multi-stage welding pressure, adjustable sonotrode reset distance, and solve the problem of instantaneous impact force under the cylinder type sonotrode.
In addition, transistor-type high-frequency power supplies have higher efficiency and smaller size compared to traditional resistance welding power supplies. This means that it can reduce energy waste and heat dissipation problems, thus achieving the purpose of energy conservation and environmental protection. The modular design of the transistor-type high-frequency power supply makes maintenance and maintenance easier and more convenient.
In conclusion, transistor-type high-frequency power supplies have many advantages in resistance welding, including good stability, high control accuracy, energy saving and environmental protection, and easy maintenance. With the continuous development and progress of power electronics technology, we have reason to believe that transistor high-frequency power supply will play an increasingly important role in the field of resistance welding and make greater contributions to the development of the manufacturing industry.
