摘要： A method for fabricating multi-sheet structures in which a first sheet is arranged on a planar support and a blowing agent is placed on at least one selected portion of the first sheet. A second sheet is positioned over the first sheet so that the second sheet overlies the selected portion of the first sheet and the first and second sheets are then secured together by friction stir welding in a pattern which encloses the selected portion of the first sheet. Additional sheets may be secured together in a like fashion. Thereafter, the sheets are heated to a temperature sufficient to decompose the blowing agent.

摘要： A friction stir spot welding tool having a rotatably driven shank. A shoulder adjacent to one end of the shank is generally circular in shape having a concave profile while a pin having a generally triangular cross-sectional shape protrudes axially outwardly from the shoulder. To perform the spot welding operation, the shank is rotatably driven and the shoulder is plunged into the workpiece such that the pin penetrates past the workpiece interface to a predetermined depth to perform the spot weld.The proposed triangular pin tool is found to significantly increase the weld strength when compared to conventional pin shaped tools due to the following: (1) it inhibits the formation of the vertical hook in the stir zone (the upward rise of the hook is arrested when the pin plunges into the workpieces interface), and (2) due to the asymmetric rotational pattern of the triangular pin it enhances the mixing of the material around the tool pin and oxide layer is dispersed (made discontinuous) in the stir zone.
摘要翻译：一种具有可旋转驱动的柄的摩擦搅拌点焊工具。与柄的一端相邻的肩部通常为圆形，具有凹形轮廓，而具有大致三角形横截面形状的销从肩部轴向向外突出。为了进行点焊操作，柄被可旋转地驱动，并且肩部被撞入工件，使得销穿过工件接口到预定深度以执行点焊。发现与常规针形工具相比，提出的三角形针工具可以显着提高焊接强度，原因如下：（1）它阻止了搅拌区中垂直钩的形成（钩的向上上升被阻止针脚插入工件接口），和（2）由于三角形销的不对称旋转模式，它增强了工具销周围材料的混合，氧化层在搅拌区域中分散（不连续）。

摘要： A method for monitoring the quality of a machining operation, such as a friction stir welding operation, in which a tool is rotatably driven by a motor during the machining operation. The energy consumption of the motor is determined from the initiation and to the completion of the machining operation. That energy consumption is then compared against a predetermined energy threshold. In the event that the energy consumed during the machining operation is less than the predetermined threshold, an error signal is generated.

摘要： A method for correcting surface and near surface defects in metal components in which the component is first inspected to identify both the site and size of a component defect. Thereafter, it is determined if the defect is correctable by friction stir processing and, if so, the defect is corrected by performing friction stir processing on the component at the site of the defect. Optionally, one of several different sized friction stir processing tools is selected as a function of the size of the defect.
