Electric resistance welding

Electric resistance welding (ERW) is a welding process that uses electrical resistance to generate heat for welding metal parts together. This type of welding is especially common for joining thin-walled materials and is often used in the fabrication of components in various industries, such as automotive, aerospace, and construction. ### Key Features of Electric Resistance Welding: 1. **Process**: In ERW, electrical current is passed through the workpieces to be welded.
