Embodiment Construction

[0031] The following description is essentially exemplary and is not intended to limit the disclosure, application or use. It should be understood that throughout the drawings, the corresponding reference numerals indicate the same or corresponding partial and characteristics.

[0032] reference Figure 1A with Figure 1B It is shown that before the joint (welding) is together ( Figure 1A ) And after joining ( Figure 1B The first closed unit structure 110 and the second closure unit structure 120. As used herein, the phrase "closed unit structure" refers to a structure defined or surrounded by an inner portion such that a pathway to the inner portion is restricted. Non-limiting examples of closed cell structures include cast or forging (e.g., squeezing) circular lines or tubular members, rectangular lines or tubers, hexagonal lines or tubes, and having two or more blocking unit structures into two or more Such a plurality of separate subunits of such piping or tubes in such lines or...

Abstract

The present disclosure provides 'inserts for enable friction stir welded joints'. A friction stir welded assembly includes a first workpiece having an interior portion with opposed interior walls, a second workpiece having an interior portion with opposed interior walls, and an insert positioned within the interior portion of the first workpiece and the interior portion of the second workpiece. The insert extends between and abuts at least one of the opposed interior walls of the first workpiece and the opposed interior walls of the second workpiece and a friction stir weld is between the first workpiece to the second workpiece. A joining end of the first workpiece and a joining end of the second workpiece form a butt joint or a lap joint between the first and second workpieces, and the friction stir weld is a butt weld or a lap weld, respectively, between the first and second workpieces.

Description

Technical field [0001] The present disclosure relates to the assembly of stirring friction welding and stirring friction welding. Background technique [0002] The statements in this section provide only background information related to the present disclosure, and may not constitute a prior art. [0003] Stirring friction welding (FSW) is a solid engagement process using frictional heat generated by a rotating tool to soften and mix metal in two parts to form binding or weld between the two workpieces. The rotating tool is inserted into a workpiece or inserted at an interface between two workpieces, and requires high contact load between the rotation tool to the workpiece to provide quality stabilizing friction welding. However, the joining of the closed cell structure can produce a joint that cannot fully support the quality of the Quality of the structure. [0004] This disclosure solves the problem associated with the FSW of the closed cell structure, and other issues related...
