    • 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.
    • 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。
