摘要： A method of efficiently manufacturing electric resistance welding pipes having excellent characterization of welded seams is provided, by which each lateral edge of a rounded strip immediately before electric resistance welding is securely shaped with desired tapering flexibly in response to change in strip thickness, so that welding quality may be kept to be excellent. A method of manufacturing electric resistance welding pipes, in which a strip 20 is subjected to forming, then edges thereof are confronted, and then the edges are subjected to electric resistance welding to form a pipe 30, includes a process that an edge and an edge opposed thereto at one of an upper-surface side and a lower-surface side of the strip are shaped with tapering before the forming by means of cutting or shaving 3, or finpass forming 4.

摘要： Side hole-bearing tubular bodies made of metal and having an inside diameter of up to 2mm are manufactured by a method which includes punching from a metal sheet (1) a sheet blank (2) in the developed shape of a tubular body and punching in the sheet blank (2) a hole (4) which corresponds to the side hole in the tubular body and/or notches (4a,4b) which form the side hole (4) when the sheet blank (2) is pressed into a tubular shape, in such a way that the metal sheet (1) and the sheet blank (2) remain partly joined; pressing the sheet blank (2) into a tubular shape; and cutting apart the metal sheet (1) and the sheet blank (2) where they remain joined. Metal tubular bodies manufactured in this way can have one or more side holes (4) of any shape, position or number thereon, and are highly suitable for use in medical devices such as syringe needles.

摘要： In order to form tailored tubular blanks (20), the girth weld seam (13) and the longitudinal weld seam (18) are positioned in such a way that the seams do not intersect one another, but merely form a junction point (14, 15). This enables the production of tailored tubular blanks which have improved ductility.

摘要： The invention relates to a method for producing welded Cu and Cu alloy pipes in a combined production line, comprising a casting installation for ingoing materials, a hot-rolling mill, a pipe forming and welding installation and a drawing device for the welded pipe. The inventive method is characterized by the following steps: a) a quasi continuous initial strip is cast, b) the cast initial strip is hot-rolled at a rolling speed = casting speed x extension to form an intermediate strip, c) the intermediate strip is cooled at
