Top 10 AC Resistance Welder Factory in China 2025

Introduction to AC Resistance Welder

AC resistance welding is a widely - used welding process that joins metals by applying pressure and passing an alternating current (AC) through the parts to be welded. The resistance of the metal to the flow of current generates heat at the interface of the workpieces, causing them to melt and form a weld joint. AC resistance welders are known for their simplicity, relatively low cost, and high - speed welding capabilities. They are commonly used in various industries such as automotive manufacturing, electronics, and metal fabrication for joining sheet metals, wires, and other small - to - medium - sized metal components.
