Abstract
A method for the manufacture of welded tubes is provided. The tube bodies are produced in a press or rounding apparatus and are fed to a welding machine, such as a laser or electron beam type welding machine. The tube is formed when the edges of the tube bodies are welded together. The method includes the transfer of the tube bodies from the press or rounding apparatus to the draw-in of the welding machine. One or more transfers modules, each having a separate drive, are used to convey the tube bodies. The one or more transfer modules, which are operated by a common control arrangement, are controlled so that the intermittently formed tube bodies are presented at the draw-in to the welding machine in as nearly continuous a sequence as possible.
