摘要： A radiused corner support plate is used to form a corner void when making L- and T-corner welds that are filled with plasticized work piece material during friction stir welding to form a filleted corner weld. An improved friction stir welding tool uses either disrupting features such as crossed rectangular grooves in the distal tip end or a curved tip region or both to improve plasticized work piece material flow below the distal end and in the region of the fillet.

摘要： A portable inertia welder is mounted in a housing so as to afford both axial and rotational movement of a shaft with flywheel weights. Rotational motion is provided by a motor affixed to the drive shaft while axial motion is provided by means of a hydraulic housing mounted around said shaft. A chuck mounted to the shaft holds a first workpiece for rotational and axial displacement. Holding devices such as vacuum cups secure the welder to a second workpiece. A flash cutting tool and an appurtenance with a flash trap, welding flats, and an internally threaded bore are described.

摘要： A method for forming a clad structure utilizing a moving resistance energy source. The method forms a metallurgical bond between a cladding layer and a primary layer such that at least 2% of a cladding layer surface is metallurgically fusion bonded to a primary layer surface. The fusion bond does not extend all the way through the primary layer or the cladding layer. Either, or both, of the layers may incorporate surface texturing to reduce the contact area between the layers, and melting point suppressants may be incorporated into the method.

摘要： The apparatus (50) includes a friction stir welding tool (100), a local clamping means (200), and an interface (300) that joins the tool (100) and the local clamping means (200). The local clamping means (200) is in close proximity to the at least one sidewall (130) of the tool (100) and has a housing (210) and a plurality of contact devices (220). The local clamping means (200) transfers a clamping force to the first and the second components (C1, C2) and holds them firmly in place during welding. The local clamping means (200) includes a plurality of contact devices (220) that may take the form of casters, rollers (222), and ball bearings (224). The location of the contact devices (220) is significant as external clamping is greatly reduced, and often eliminated, as the contact devices (220) are brought into close proximity to the area of the weld.

摘要： A friction stir welding (FSW) travel axis load control method and apparatus for controlling a travel axis load applied to a FSW setup during the joining of workpieces by FSW. The method and apparatus recognize that controlling certain attributes of a friction stir welding plasticized region are key to controlling the quality of the resulting weld. This invention controls any of a number of qualities associated with the plasticized region thereby producing welds having improved mechanical and aesthetic properties, as well as extending the life of the FSW tool. The method and apparatus may control the FSW process to obtain a predetermined optimum size of a heat affected zone. The plasticized region may be monitored in a number of ways including, but not limited to, force on the tool, torque applied to the tool, workpiece temperature, plasticized region physical dimension, as well as changing surface characteristics such as color and reflectivity.
