Embodiment Construction

[0028] The following discussion provides various exemplary embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is contemplated to include all possible combinations of the disclosed elements. Thus, if one embodiment includes elements A, B, and C, and a second embodiment includes elements B and D, the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D even if not expressly disclosed .

[0029] It should be appreciated that the disclosed technique provides a number of advantageous technical effects, including an improved FSW device for simultaneously welding opposite sides of an arcuate joint.

[0030] figure 1 A method 100 is shown for friction stir welding an arcuate joint, such as a joint formed by joining the ends of two pipe sections. In step 110, a first FSW tool (eg, a tool with a needle and shoulder) is operated on the...

Abstract

Friction Stir Welding (FSW) devices and methods for simultaneously welding both sides of an arcuate joint are described. The FSW method includes the step of operating a FSW tool and an anvil on the exterior surface of the joint and simultaneously operating another FSW tool and anvil on the interior surface of the joint. The anvils are positioned in a juxtaposing manner to the FSW tools, and move in tandem with the FSW tools, thus providing a supporting force to the FSW tools during their operation.

Description

technical field [0001] The field of subject matter of the invention is friction stir welding. Background technique [0002] The background description includes information that may be useful in understanding the inventive subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication referenced, explicitly or implicitly, is prior art. [0003] Friction stir welding ("FSW") is a solid state welding process in which a rotating tool (hereinafter "FSW tool") heats and intermingles two workpieces at the joint. More specifically, rotary tools have needles and shoulders that are pressed into the seam as the tool rotates, creating frictional heat between the tool and workpiece. Sufficient heat is generated to plasticize and mix areas of the workpiece. The shoulder of the FSW tool helps to cause commingling of the plasticized zone to join these workpieces at the seam (i.e....
