A method of producing a welding seam with a single laser pulse, the laser pulse and the work piece being moved relative to each other at a high velocity. This results in the length of the welding seam formed being primarily the product of pulse duration of the laser pulse and the relative velocity of work piece and laser pulse. The invention also relates to a method in which the work piece moved at high velocity relative to the laser beam is subjected along the welding seam to be formed to repeated applications of a single laser pulse. In that case the length of the welding seam is defined principally of the product of pulse duration of the laser pulse and the relative velocity of the work piece and laser pulse divided by the number of applications.
