Abstract: The invention relates to a rotatable, plungeable and free path travelable non-consumable tool (5) for production of a channel (2) and a weld joint (1). The tool (5) comprises a shoulder and a probe, the shoulder having a surface facing the material(s) of components (3) 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 (3) to be processed. The shoulder facing the at least two components (3) to be processed has a system of scrolls shaped to have an inward action and an outward action on the at least two components (3) 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 (3) 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 (3) to be processed in a direction towards the tip. The tool (5) enables the production of a channel (2) and a weld (1), between said at least two components (3), in one single action.
