ABSTRACT:
To make a container with a butt welded longitudinal seam, the side edges of a preformed blank are guided by straight grooves so that the side edges converge at an acute angle. At the point of convergence the side edges are heated to at least to the forging temperature, preferably by a focused laser beam. The side edges are then tangentially compressed before they cool.
