摘要： An additive manufacturing process (110) wherein a powder (116) including a superalloy material and flux is selectively melted in layers with a laser beam (124) to form a superalloy component (126). The flux performs a cleaning function to react with contaminants to float them to the surface of the melt to form a slag. The flux also provides a shielding function, thereby eliminating the need for an inert cover gas. The powder may be a mixture of alloy and flux particles, or it may be formed of composite alloy/flux particles.

摘要： Gegenstand der Erfindung ist ein Verfahren zur Herstellung eines Karosserie-Tragrahmens (Synecon-Frame) und ein nach diesem Verfahren hergestellter Karosserie-Tragrahmen (16; 17). Bei dem erfindungsgemäßen Tragrahmen ist die A-Säule (1) werkstoffeinstückig mit dem Dachlängsträger (2) verbunden und als durchgehendes Profilteil (1; 2) entsprechend in sich gebogen. Weitere Profilteile wie z. B. die B-Säule (4) und die A-Traversen (7; 8) sind über Fügestöße (11) mit diesem durchgehenden Profilteil (1; 2) verbunden. Diese Fügestöße (11) werden durch sowohl in dem durchgehenden Profilteil (1; 2) ausgebildeten Ausklinkungen (21) als auch durch Ausklinkungen (32) an den Enden der daran anschließenden Profilteile definiert. In der Elektronenstrahlschweißanlage durchläuft der Tragrahmen (16) mehrere Evakuierungskammern (1; 2) bis schließlich in der Schweißkammer (3) die exakt aufeinander abgestimmten Fügestöße (11) mittels einer vorzugsweisen numerischen freibewegbaren Elektronenstrahlkanone im Vakuum verschweißt werden. Der mit diesem Verfahren hergestellte Tragrahmen weist ein besonders vorteilhaftes dynamisches Verhalten auf, da dieser durchgehende Längsträger aufweist und diese mit Hilfe des Elektronenstrahlschweißens in einem sehr lokal begrenzten Bereich exakt mit den übrigen Tragrahmenprofilen verbunden sind.

摘要： A method and apparatus for electroslag surfacing of metal plate which utilizes a plate feeder assembly to which the plate is presented and which includes an elongate, horizontally disposed feeder table having an approach-end section and a runout-end section. The plate, with a major surface uppermost, is conveyed along the feeder table in a feeding direction from said approach-end section to said runout-end section, and is subjected to an electroslag operation at a surfacing installation located intermediate those sections to provide a cladding metal layer on that surface. At the surfacing installation, there is a flux mould arrangement under an electrode holder and feeder assembly having depending electrodes vertically in line with the interior of the mould arrangement. The plate is passed under the mould arrangement and the electrode holder and feeder assembly is vertically adjusted to bring a lower end of the electrode means into contact with the upper surface and to establish current flow. On establishing current flow, the electrodes then are raised to establishing an arc between the electrodes and the uppermost surface, with charging of flux to mould arrangement establishing a molten slag pool which overlies that surface to submerge and extinguish the arc. Alloy powder material to said mould arrangement at the interface between the slag pool and the uppermost surface and melted in said mould arrangement to clad the uppermost surface as the metal plate is conveyed under the mould arrangement.

摘要： Apparatus for cladding and thus reclaiming a worn rolling mill roll by fusing a surface layer thereon, comprises an electro-slag mould (7); a slewable derrick structure (Fig. 2) able to feed a split tubular, consumable electrode (51) into the mould; a turn-table (8) supporting the mould; a tiltable induction furnace (55) to charge the mould with molten flux; product transport means (Fig. 1) to lift a worn mill roll through the mould and withdraw it downwardly from the mould as cladding proceeds and comprising rigid hangers (12) extending downwardly from the turn-table, an elevator carriage (14) with a product holder and adapter including a mould plug (29), and power driven jack screws (19) to raise and lower the carriage (14); and drive means (9, 11) to cause rotary oscillation of the turn-table and the components carried by it, including the roll, relative to the electrode. A method of cladding a worn roll by the electro-slag process is also disclosed wherein the mould and roll are rotationally oscillated about the axis of the roll relative to the electrode, as cladding proceeds.
