Along the two longitudinal edges of the band, the first metal is removed from the second metal in strips which run over the entire length of the band. The band is formed into the open-seam pipe with the first metal located on the outside, and the abutting edges of the layer of the second metal are welded to one another forming a pipe which is closed all the way round. In the region of the weld seam, a layer of the first metal is then deposited on the second metal to produce a pipe with a layer of the first metal which is closed all the way round.
