Abstract
The invention relates to a rotatable, plungeable and free path travelable non-consumable tool () for production of a channel () and a weld joint (). The tool () comprises a shoulder and a probe, the shoulder having a surface facing the material(s) of components () to be processed. The shoulder and the probe are arranged to have a simultaneous and synchronized action in the materials of at least two components () to be processed. The shoulder facing the at least two components () to be processed has a system of scrolls shaped to have an inward action and an outward action on the at least two components () to be processed. The probe has a cylindrical or conical surface having a top zone, provided with a profile having a push-up action on the components () to be processed in a direction towards the shoulder. The top zone ends at or in the vicinity of a bottom zone provided with a profile having a push-down action on the components () to be processed in a direction towards the tip. The tool () enables the production of a channel () and a weld (), between said at least two components (), in one single action.
