    摘要: Bei einer Unterpulver-Schweißvorrichtung mit mehreren Drahtelektroden werden eine beliebige Anzahl Drahtelektroden (D) in geringem Abstand zueinander von einer entsprechenden Anzahl, gegebenenfalls in mehreren Ebenen übereinander angeordneten, angetriebenen Vorschubrollen (6) gegen die jeweils druckbeaufschlagten Gegenrollen (7) wirken, über ein an die Vorschubeinrichtung (I) angeflanschtes Schweißschwert (II) geführt. Die Drahtelektroden (D) sind untereinander durch isolierte Führungsrohre (15) getrennt. Zur Sicherstellung der Schweißstromüber­tragung von der am Schweißschwertende angebrachten auswechselbaren Strombacke (12) zu den Drahtelektroden (D) werden diese mit einstellbaren druckbeaufschlagten Hebeln (18) an die Strombacke (12) gedrückt.

    摘要: A submerged arc welding gun includes a housing (14) having a bore (26) extending therethrough. The housing includes a welding nozzle (16) defining one end. Welding wire (20) is directed through the bore of the housing to said nozzle. A flux tube (22) is disposed in spaced relation to the welding wire for delivering flux from a source (12) thereof to the nozzle. The flux tube terminates substantially adjacent to the nozzle. The flux tube (22) is connected to a source of pressure for feeding the flux through the tube to the nozzle.

    摘要: An electric melting method for forming a cylinder of a pressure vessel of nuclear power station, in which an electric melting head and a base material are connected to the anode and cathode of a power supply respectively. During the forming of a metal component, the raw metal wire is sent to a surface of the base material by a feeder and the electric melting head to create the electric arc between the raw wire and the base material under the protection of the deposit of granular auxiliary material, wherein the electric arc melts certain of deposited auxiliary material and crates a molten slag pool; a current flows through the raw wire and the molten slag pool to create the resistance heat and the electroslag heat; the raw wire is molten under the high-energy heat resource composed of the electric arc heat, the resistance heat and the electroslag heat, and creates a molten pool on partial surface of the base material; the raw wire and the auxiliary material are continuously fed and a computer is used to control the relative movement between the electric melting head and the base material based on laminated slice data of the formed components, such that the molten pool is rapidly cooled, solidified and deposited on the base material and thus forms the cylinder of the pressure vessel of the nuclear power station. Such method is high efficiency and low cost, as well as excellent mechanical performance.
