A sheet metal welding process is described in which limited zones of contact of metal sheets (A, B) are heated locally by a power laser so as to cause fusion in the manner of spot or seam welds (P, C). Such spot or seam welds are achieved by deep penetration welding of juxtaposed metal sheets joined by a plurality of welding spots or seams, these may be spaced apart such that the sheet metal portions between the spots or seams can deform in an elastic-plastic manner under stress. |
