    摘要： An operation management device performs an operation management for electric resistance welding in which a strip-shaped metal plate is formed to have a cylindrical shape in such a manner that both end portions of the metal plate gradually face each other while the metal plate is conveyed, and a Vee convergence section, which is a portion at which both of the end portions butt against each other while facing each other, is welded. Furthermore, the operation management device includes: a measuring unit that measures a distance L [mm] between a first Vee convergence point at which both of the end portions of the metal plate geometrically come into contact with each other and a second Vee convergence point that is a contact point of both of the end portions of the metal plate, and a Vee convergence angle θ[°] at the first Vee convergence point on the basis of an image of an area including the Vee convergence section; and a determining unit that determines whether or not the distance L [mm] and the Vee convergence angle θ[°] satisfy the following equation (1). Lmin(θ/θst)−0.15≦L≦35  (1)

    摘要： A method for interconnecting tubulars by forge welding involves arranging the tubular ends that are to be interconnected at a distance, up to a few millimeters from each other in a shield gas chamber, into which a reducing non-explosive flushing fluid mixture (e.g. N2+H2) is injected; heating each tubular end within the space by means of at least three electrodes that are pressed at circumferentially spaced intervals against the wall of each tubular, adjacent to the tubular end such that a high frequency electrical current is transmitted in a substantially circumferential direction through the tubular segments between the electrodes; and moving the thus uniformly heated tubular ends towards each other until a forge weld is formed between the heated tubular ends.

    摘要： A high-frequency electric resistance welding method combined with the irradiation of a laser beam in which a workpiece is continuously fed and opposed edges of the workpiece are formed into a wedge shape by causing them to converge as they are butted against each other, and the butted edges are melted by heating them with high-frequency resistance heating and a laser beam, to weld the butted edges. The laser beam is projected against the range of over 30% and below 80% of the thickness of the butted edges including the central portion of the thickness to melt the butted edges by the combined heating action of the laser beam and high-frequency current. The corners are heated and melted by means of high-frequency electric resistance heating, so that the butted edges of the workpiece can be melted uniformly through the entire range of thickness.

    摘要： Methods and apparatus for manufacturing welded metal tubes of finite length in which an almost complete, axially split tube is advanced into a welding head where one edge face at one side of the split is accurately positioned and clamped and then the other edge face at the opposite side of the split is pressed against the one edge face. The welding head comprises a retractable edge face guide for said one edge face, clamping devices for holding and applying pressure to the tube, a proximity conductor over and extending along the abutting edge faces and contacts engagable with the opposite ends of the tube adjacent the abutting edge faces and connected to a high frequency current source for electrically heating the metal adjacent the edge faces to forge welding temperature.
