    摘要: A roller for forming heat transfer elements may include a central shaft and a plurality of roller elements. The plurality of roller elements may be stacked on the central shaft. Each roller element defines an outer periphery, which is configured to include a geometrical characteristic thereacross. The stacked roller elements, either stacked on the central shaft or stacked without using the central shaft, configures the roller with a circumferential surface corresponding to the geometrical characteristic of the stacked roller elements, to form the heat transfer elements corresponding to the circumferential surface.

    摘要: A method for welding two or more conduits includes aligning end portions thereof in an abutting relationship to define a gap. The method includes performing a spatter free root weld along the gap to configure a root layer while the inner circumferential surface side is unobstructed. After the root weld is complete, an outward thrust is applied along the inner circumferential surfaces of the conduits. During the application of the outward thrust, a filler weld is performed along the gap to fill the gap and to facilitate shrinkage of the filler and root weld materials longitudinally and radially outward while preventing pressing out of the filler and root weld materials radially inward of the inner circumferential surface.
