Flash welding

Flash welding is a type of resistance welding process used primarily for joining metal components. It involves the creation of a localized high-temperature area through electrical resistance, which then allows the metal surfaces to fuse together without the need for filler material. ### Key Points about Flash Welding: 1. **Process**: During flash welding, the ends of the workpieces are brought into contact under pressure. An electric current is then passed through the contact area, generating resistance heat.
