Abstract (en)
[origin: EP1997569A1] The method involves bringing a three-dimensional contour of ends (7) of a longitudinal seam welded tube (20) with a measurement into an uncoiled blank section (6). The three-dimensional contour of the ends is brought with a measurement by a mechanical trimming tool into the longitudinal seam welded tube. The ends of the tube are inductively heated, and are accurately compressed by a form mandrel to the dimension of a length and contour.
