    Abstract: In a method for producing a cellular wheel made of metal, the following steps are conducted consecutively: (a) providing a sheet metal strip (26) having a length (1) that corresponds at least to the length of a circumferential line of an intermediate sleeve and a width (b) that corresponds at least to the length of the cellular wheel; (b) placing disks (16) in predetermined locations in predetermined quantities on both sides of the sheet metal strip (26) perpendicular to the sheet metal surface and perpendicular to the longitudinal direction of the sheet metal strip (26) and connecting the disks (16) to the sheet metal strip (26) by welding or brazing; (c) bending the metal strip (26) equipped on both sides with the disks (16) and connecting the two ends of the sheet metal strip (26) by welding or brazing to form the intermediate sleeve; (d) placing a first tubular sleeve that is concentric to the intermediate sleeve as an outer sleeve, and a second tubular sleeve that is concentric to the intermediate sleeve as an inner sleeve, and connecting the free ends of the disks (16) to the outer sleeve or the inner sleeve by welding or brazing. The method allows cellular wheels to be produced which have material wall thicknesses of 0.2 mm and less for use in pressure wave superchargers.

    Abstract: Superalloy components (40, 50) are joined by mating a recess (44) formed in one component (40) with a corresponding projection (52) formed in another component (50) along a contact surface. The components are compressed along the contact surface and resistance heat brazed to each other. Current is passed between the components (40, 50) at a selected flow rate and application time until brazing alloy (60) melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component (40), the damaged portion is removed to form an excavated recess (44). A repair splice (50) is formed, preferably of a same material with similar mechanical structural properties, having a mating projection (52) with profile conforming to the corresponding recess (44) profile. The splice (52) and substrate (40, 50) are resistance heat brazed under compression pressure until brazing alloy (60) melting occurs along the contact surface, so that they are mutually affixed.

    Abstract: The subject of the invention is a method of welding of elements (4, 5) for the power industry, particularly of sealed wall panels of power boilers and steam generators. The method according to the invention consists in joining tubes (5)that form sealed walls with flat bars (4) by means of a high power fibre laser (3), wherein welding is realised as a double sided plain butt welding with no bevelling of the faces being joined, at a speed of more than 1 m/min, while the laser beam is either irradiated into a molten pool, such pool being formed in the process of MAG welding with noble gas shielding, or the laser beam is trailing after the pool up to 10 mm behind it, with the MAG process electric arc positioned at an angle 6 of 40-80° in the XZ plane and at an angle of 6 of 40-80° in the YZ plane, where the weld is remelted with the laser beam positioned at an angle of incidence α of 1-5° in the XZ plane and at an angle Y of 1-5° in the YZ plane. In another embodiment of the invention filler wire is fed into the focal point of the laser beam and/or into the molten pool, and the process is realised in the manner described above.

    Abstract: The invention relates to a finned tube (1), a process for making it and a device for implementing the process. In the process, at least one endless strip (4) forming the fins is wound approximately helically about a rotating tube body (2) and the narrow edge of the strip (4) facing the tube body (2) is secured to the tube surface by a welding device (7). In order to be able to operate economically and to save energy and provide a product in which the fin is secured to the tube surface over the entire width of its foot in the best possible way and the joint region is a good heat conductor, the working end of the welding device (7) is guided in the free wedge between the tube surface (3) and the strip (4) to be wound thereon, whereby a weld bead (11) is applied by the welding device (7) to the tube surface using a weld metal before the narrow edge of the strip (4) is applied which runs exactly in the bonding region of the strip (4) and the tube surface (3). The narrow edge of the strip (4) is then pressed into the still molten weld bead (11).

    Abstract: Ein Verfahren zum Befestigen von vorzugsweise senkrecht stehenden Außenrippen auf Rohren mit vorzugsweise von der Kreisform abweichendem Rohrquerschnitt und dünner Rohrwandung, vorzugsweise von Verstärkungs- oder Kühlrippen auf Strahlrohren für spätere Einbeulbelastung durch UHV und ovalem Querschnitt durch Auflöten der Rippen auf den Rohrgrundkörper. Dabei werden die linearen thermischen Ausdehnungskoeffizienten der Materialien für Rohrgrundkörper und Rippen so gewählt, daß bei Raumtemperatur ein relativ großer Montagespalt, bei Löttemperatur jedoch ein möglichst enger Lötspalt zwischen Außenfläche des Rohrgrundkörpers und Innenkontur der Rippen entsteht. Außerdem wird der Rohrgrundkörper während des Lötens oder kurz vor dem Erreichen der Löttemperatur durch Aufbringen eines inneren Überdrucks aufgeblasen und gegen die Innenkontur der Rippen gepreßt.
