Abstract
The invention relates to a method and to a device for welding together two joining partners by means of friction stir welding, which prevents the joining partners being contaminated by welding residue. The method comprises the following features: a welding head that can be integrated into any machine, said welding head being in the form of a spindle drive driven by a drive unit, comprising a mounting flange for securing the device assisting the welding process, and a clamping system for receiving a frustoconical-shaped tool having a welding and smoothing shoe for guiding a welding pin (), a device () integrated into the welding and smoothing shoe for grinding the waste produced during the welding process, the waste produced during welding is then removed by means of one inlet channels for fluid arranged in the upper and/or lower area of the frustoconical-shaped tool for the fluid () and a suction channel ().
