Flashbutt welding process

WebFlash-Butt Welding (FBW) is a resistance welding process, employing current, time, and force to achieve solid state joints (Ref. 1). These three parameters are managed separately within the two major segments of the process: Flashing and Upset. During flashing, a voltage is applied across the ends of two work pieces. WebIn general, flash butt welding is a typical butt welding method of resistance welding. Flash butt welding is a welding method in which resistances are generated by a high current...
