Flash Butt-Rim Welding

Flash Butt-Rim Welding is a specialized resistance welding process used to join the ends of metal components, particularly in circular or rim-shaped parts. The process involves generating heat through electrical resistance while the parts are brought together under pressure, causing the metal to flash and forge a solid, uniform weld. It is widely used in the manufacturing of wheel rims, rings, and circular components where precision, strength, and alignment are critical. Flash Butt-Rim Welding is a high-precision resistance welding technique commonly used to join circular components like wheel rims, rings, and tubes. The process involves clamping the two workpieces, applying

high current, and bringing them together slowly. As the metal heats and flashes at the joint, the material becomes plasticized. A final forge force is applied, resulting in a strong, seamless weld. This method ensures excellent joint strength, minimal material distortion, and superior alignment, making it ideal for automotive wheels, railway components, and pressure-resistant ring-shaped assemblies.
