Verfahren zur Erzielung einer dekorativen Außenfläche bei der Herstellung gerippeversteifter Blechbauteile, insbesondere bei der Seitenwandherstellung von Schienenfahrzeugen

摘要

A procedure for creating a decorative outside surface on stiffened plates, like the side panels of rail vehicles, has a framework made of Z- shaped or angle profile section, 1 to 3 mm thick, laid on plating of the same thickness and joined to it using a carbon dioxide laser and either lap- or parallel- welding. The profile section (3) and the plating are welded with an equal or much smaller binding zone width than the weld seam width of 0.6 to 1.2 mm and with almost parallel seam edges, where a total weld depth between 1.5 and 5 mm and a laser optic burning width between 80 and 300 mm is attained. The minimum welding speed is one metre per minute using 1 to 5 kW beam power.
