| Zusammenfassung: | An electrically assisted friction stir welding method and arrangement in which the required downward/pressing force typically exerted on a workpiece is substantially reduced. The method and apparatus involves the creation of a localized heated zone on a workpiece undergoing a welding operation. The localized heated zone is created using a resistive heating circuit running through the friction stir welding tool and the workpiece. |
