    摘要： A continuous manufacturing method for a metal welded tube and a manufacturing apparatus therefor, which obtains a tubular member by continuously passing a metal band coil through molding rollers, guides the tubular member to abutting rollers to bring the edges thereof in slight contact with each other so as to form a V-throat having the vertex of an edge contact portion at the upstream side of the abutting rollers, disposes an inductor of a high frequency preheating unit aiming at edge preheating at the outer periphery in front of the abutting point of the V-throat and at need disposes an impeder also at the inner surface of the V-throat, and further disposes welding torches in a single or double rows of a welding unit for melting and welding the tubular member by welding high density energy at the upstream side of the abutting rollers including the line connecting the centers thereof.

    摘要： An apparatus for guiding can bodies in a laser welding machine is described. The apparatus comprises a water-cooled holding-down shoe (22) with an integrated holding-down roller (24), gas supply (64) and suction extraction (68), the holding-down roller (24) being disposed in front of the theoretical point of intersection of the two edges of the body to be butt-welded and being adjustable in height, with the holding-down shoe (22), to the thickness of the sheet metal. Adjacent to the holding-down shoe (22) is a holding-up shoe (26) and adjacent to the holding-down roller (24) is a holding-up roller (28). Provided below the holding-up shoe (26) is a horizontally and vertically adjustable supporting roller (30) which supports the can bodies at their underside during the welding operation and during passage through the welding plane (10). The bringing together of the edges of the bodies to be butt-welded, which emerge from the Z-rail, is effected by means of this apparatus without much friction and wear, the welding position is protected and any smoke formed during the welding is drawn off. As a result of the supporting roller, too close an adjustment of the conveying means is avoided, through which increased power requirements and wear in the guide range of the Z-rail would be caused.

    摘要： Method and apparatus for laser-beam welding of longitudinal seams in container bodies feature overlapping longitudinal ends of a metal sheet, the length of the transverse ends of which exceeds a predetermiined circumferential dimension for the container body, into such a position relative to one another that they form an acute angle and define an angular opening, and the edge of one longitudinal end is oriented toward the inner face of the other longitudinal end. At least one focused laser beam, which is capable of relative movement with respect to this angular opening and parallel to the longitudinal ends, is aimed into the angular opening and locally melts portions of the longitudinal ends. The locally-molten longitudinal end portions are pressed against one another before they drop below the welding temperature to form a welded longitudinal seam.

    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： A method of forming a continuous laser butt weld between two members is disclosed. The method comprises providing two members to be butt welded, positioning respective edges of the members in abutting contact with the two members being canted slightly with respect to one another so that the butt joint formed by the edges is open toward a first side of the member, with the edges contacting one another toward a second side of the members opposite the first side, and directing a high energy density laser beam at the butt joint from the first side of the members so that at least a portion of the laser beam extends into the open side of the butt joint to the edges, while urging the edges of the two members in the direction of the butt joint for butt welding the members.
