    摘要： The present invention provides a friction stir welding apparatus operable for welding one or more metals, metal alloys, or other materials. The friction stir welding apparatus includes a pin tool holder, a shoulder having a surface coupled to the pin tool holder, and a pin tool coupled to the pin tool holder, the pin tool at least partially protruding from the surface of the shoulder, wherein the pin tool is made of a consumable pin tool material. Optionally, the shoulder rotates at a predetermined rotational speed and is retractable into/extendable from the pin tool holder at a substantially constant rate. Optionally, the shoulder is also made of a consumable shoulder material that is at least partially incorporated into the volume of a joint to be welded. The consumable shoulder material comprises a material that is the same as, similar to, or dissimilar from one or more materials comprising a workpiece to be friction stir welded. Preferably, the pin tool rotates at a predetermined rotational speed and is retractable into/extendable from the surface of the shoulder at a substantially constant rate. The consumable pin tool material is at least partially incorporated into the volume of the joint to be welded. The consumable pin tool material comprises a material that is the same as, similar to, or dissimilar from one or more materials comprising the workpiece to be friction stir welded.

    摘要： An aluminum tubular unit for long-term, leak-free storage of fluids is formed in which an aluminum cap is ultrasonically welded to an end of the aluminum tube. The ultrasonic weld is formed from a device capable of producing a torsional vibration pattern. The ultrasonic welding of the cap to the tube eliminates the use of seals and pins to seal the cap to the tube and further eliminates the need for having a hole in the cap to mechanically couple the respective end cap to the cylindrical tube. Furthermore, since ultrasonic welding does not generate significant heat, highly volatile and flammable fluids can be present within the tube when the caps are ultrasonically welded to the cylindrical body. In addition, one or more fins used may also be welded to the outside diameter of the cylindrical body using a related ultrasonic welding process.

    摘要翻译： 形成用于长期，无泄漏地存储流体的铝管单元，其中铝盖被超声波焊接到铝管的端部。 超声波焊接由能够产生扭转振动图案的装置形成。 将盖超声波焊接到管上消除了使用密封件和销来将盖密封到管上，并且进一步消除了在盖中具有孔以将相应的端盖机械地联接到圆柱形管的需要。 此外，由于超声波焊接不会产生显着的热量，所以当超声波焊接到圆柱体时，管内可能存在高挥发性和易燃液体。 此外，使用相关的超声波焊接工艺也可以将所使用的一个或多个翅片焊接到圆筒体的外径上。

    摘要： A method of friction stir welding and a non-consumable retractable shoulderless variable penetration friction stir welding tool. The tool includes a substantially cylindrical body portion, a head portion, and a tip section, each integral to the tool. The body portion has a longitudinal axis about which it is rotable, a diameter, a sidewall substantially parallel to the longitudinal axis, a proximal end, and a distal end. The head portion is located at the distal end of the body portion. The head portion has a base with a diameter substantially equal to the diameter of the body portion thereby forming a smooth transition between the body portion and the head portion, thus, the tool has no shoulder. The head portion includes a face that converges to the tip section. The tool is retractable, reduces overheating, improves weld quality by reducing internal voids and lack of fusion, and facilitates variable penetration welds.

    摘要： A method for repairing defects in a substrate comprising the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; placing at least one electrically conductive cover sheet in contact with a portion of the consumable filler slug; bringing a first electrode and a second electrode in contact with the at least one cover sheet and applying a force; and transmitting electrical current between the electrodes, thereby resistively heating the at least one cover sheet and conductively heating the consumable slug and a portion of the substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under pressure. Alternative embodiments eliminate the need for the conductive cover sheet(s) by utilizing electrodes having increased electrical and thermal resistance. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers.
