摘要： PROBLEM TO BE SOLVED: To provide a method for continuously manufacturing a copper pipe having a thin wall thickness and a very long length welded with a laser beam. SOLUTION: The method for manufacturing the metallic pipe is that a strip 1 of copper or a copper alloy is continuously drawn out of a feeding part of the strip and is formed into a slit pipe which has butted strip ends, and the strip ends are welded with a laser beam 9. At least the strip ends are mechanically roughened to a surface roughness Ra=12.5 μm or greater before welded and made wet with a liquid hydrogen oxide before welded.

摘要： PROBLEM TO BE SOLVED: To provide a metal tube manufacturing method and an apparatus therefor capable of preventing a tool from cold sticking. SOLUTION: A thin metal strip 1 liable to cold stick is gradually formed to a tube with a slit, its seams butted/in tight contact on each other are welded to each other, the welded tube is reduced in diameter. A tube with a slit of the metal strip is formed by metal forming rolls or metal forming drums 4a, 4b, 5a, 5b, 6a, 6b acting in pairs while rotating in the direction opposite to each other. These forming rolls or forming drums guide hem parts of the metal strip to be deformed. In this case, the metal strip are formed and guided by the forming rolls, the forming drums or its both, and reduced by rolls 11, a surface hardness of these rolls and drum is >=100 GPa.

摘要： PROBLEM TO BE SOLVED: To provide a method by which a tube having a deeper waveform or a smaller pitch is manufactured and the waveform is a uniform shape viewed from the length direction of the tube at this time. SOLUTION: A metallic strip is formed into the longitudinal slit tube and, the longitudinal slit is welded and preferably the waveform is formed with a corrugating tool. The corrugating tool is eccentrically supported and inclined to the axis of the tube and attached to a corrugating head which is rotationally driven in the freely rotatable state and hobbing is performed on the surface of the tube. The metallic strip and the metallic tube which is not yet corrugated is moved toward the front with an drawing apparatus. A 2nd drawing apparatus 8 is engaged with the corrugated tube 7 just behind a corrugating device 6 and the drawing speed of a 2nd drawing apparatus is lower than the advancing speed of the corrugated tube 7 which is produced from the inclination of a corrugating ring and the rotational speed of the corrugating head.

摘要： PROBLEM TO BE SOLVED: To provide a horizontal seam welding method which solves a problem that a combustion hole can be generated in a strip edge at a leading part and a terminating end of a weld joint when performing the horizontal seam welding with an arc welding torch. SOLUTION: In a method for performing the welding between the ends of two metal strips, and butted ends are joined with each other with a TIG torch horizontally movable in the longitudinal direction of the metal strips. Thin pieces 9 and 10 are abutted on the long edges of the metal strips 1 and 1a in a butted area, the thin pieces 9 and 10 are connected to the edges in the longitudinal direction of the metal strips by means of a spot weld of the TIG torch in the butted area, and the strip end parts are welded to each other by moving the welding torch along the butted edges. The welding torch is ignited on one of the thin pieces, and moved up to the thin metal plates 9 and 10 facing each other, and the thin metal plates 9 and 10 are removed from the long edges.
