Zusammenfassung:A contour cut door beam for automobiles, and apparatus and method of forming same. A steel tube is contour cut with a laser beam from a source offset from an operative axis coincident with the tube axis, using simultaneous rotational and linear advancement between the tube and cutting beam to form an arcuate outer end terminus on the tube in a plane transverse to the axis, an arcuate inner terminus on the opposite side of the tube in a second plane transverse to the axis, and a pair of mirror image contoured edges joining said termini, with all portions being on radii relative to said axis.
