摘要
The invention relates to a method for producing gilled metal pipes. According to the method, at least one continuous, gill-forming strip is applied to a rotating pipe body at a tangent and unwound onto the pipe body in an approximately helical line. The side of the strip facing towards the pipe body is connected to the pipe surface by a welding device, using an additional material. The welding process is optimized and the finishing quality increased by molding a web that is bent at right angles to the strip that forms the gills before the strip is wound onto the pipe body. The strip is preferably bent into a U-shape and the web, which runs between the two limbs of the U-shape, is guided flatly onto the pipe body.
