1. Introduction
Industrial welding is an important process for connecting metal components in modern manufacturing, widely used in many fields such as automotive manufacturing, shipbuilding, aerospace, etc. With its unique performance characteristics, high voltage power supplies play a crucial role in improving welding quality and efficiency, and have become the core components of industrial welding equipment.
2. Application Principles of High Voltage Power Supplies in Industrial Welding
During the industrial welding process, high voltage power supplies generate high voltage and high current arcs to provide the required energy for welding. Taking arc welding as an example, the high voltage power supply converts the input electrical energy into arc heat energy, generating a high temperature arc between the electrode or wire and the workpiece, melting the metal and forming a weld. When working, by precisely controlling parameters such as the waveform and frequency of the output voltage and current, it can adjust welding process parameters such as arc stability, penetration depth, and deposition rate to meet the welding requirements of different materials and workpieces of different thicknesses.
