Embodiment Construction

[0029] Hereinafter, the present invention takes the form of preferred embodiments with reference to figure 1 to 6 for more detailed description.

[0030] exist figure 1 shows the structure of at least two components as obtained in the present invention. The structure of at least two parts consists of three metal plates joined together by a weld 1 and an internal closed channel 2 which, thanks to the process of the invention applied to several parts 3, passes through a simultaneous Actions take shape.

[0031] figure 2 The figures show a number of different ways or designs of applying the process of the invention.

[0032] a) Overlap joint design, where three parts 3 overlapping each other are formed by forming channels 2 and welds 1 between all three parts 3 . Symbols m and n in the figure indicate the number of components 3 .

[0033] b) Butt joint design where two parts 3 are welded 1 to have an internal channel 2 and form a butt joint between them. Symbols m and n i...

Abstract

The present invention relates to a rotatable, pushable, and free-path non-consumable tool for forming channels and weld joints. The tool includes a shoulder having a surface facing the material of the part to be machined and a probe. The shoulder (5b) and the probe (5a) are arranged to have a simultaneous and simultaneous action on the material of at least two parts (3) to be machined. The shoulder (5b) facing at least two parts to be machined (3) has a scroll system (13, 14) shaped to have inward and outward action on at least two parts to be machined (3). The probe (5a) comprises a cylindrical or conical surface with a top region (9) whose profile (9a) has a push-up effect on the part to be machined (3) in the direction towards the shoulder (5b). The top zone (9) ends at or near the bottom zone (10), and the contour (10a) of the bottom zone (10) has a push-down effect on the part to be processed (3) in the direction towards the tip (11). The tool is capable of forming a channel (2) and a weld (1) between at least two components (3) in a single action.

Description

technical field [0001] The present invention relates to the formation of channels and welded joints between multiple (at least two) bulk parts of similar or dissimilar materials in one simultaneous action, based on a novel concept combining solid state friction stir processing methods solution. [0002] Purpose of the invention [0003] It is an object of the present invention to provide a rotatable, pushable, free path non-consumable tool for forming channels and weld joints, said tool comprising a shoulder and a probe, said shoulder The portion has a surface facing the material of the part to be machined. [0004] Another object of the invention is: a method for solid state formation of channels and welded joints. [0005] Yet another object of the invention is a multi-part structure with closed channels and welds between at least two parts, which can be obtained by the method of the invention. Background technique [0006] Internal closed channels are structural featu...
