Abstract: A method for producing a wheel pan includes cold-rolling a rectangular metal strip of a given uniform thickness by conical rolls into a semicircular ring, such that the thickness reduction on the outer edge of the curved strip is at least 20%, and the circumference of the semicircular ring thus produced extends 130-310°, preferably 180°; bending the semicircular ring into a complete circle to produce a conical hoop, welding the ends together; and shaping the hoop to form the bottom of the pan.

Abstract: A welded vehicle wheel having a sectional rim which is connected to a nave or wheel disk in the area of the drop center by means of a weld seam, and which has standardized sections, in particular rim flange and bead seat area in terms of their axial and/or radial extent, transition radii and angles, and nonstandardized sections, in particular drop center area.

Abstract: The invention relates to a method for manufacturing components from critical cold forming of light metal strip, preferably naturally hard Al alloys of the AlMg or AlMg—Mn types, in which the desired component is manufactured from the strip by at least one cold forming step and the plasticity is improved before the cold forming by means of a soft annealing. According to the invention, it is proposed that the region of the longitudinal edges of the cold-slit strips is heated in a depth in the strip width of at least 1 mm to a maximum of 10 mm in such a way that a temperature of over 150° C. is reached over a time span of more than 0.1 seconds to a maximum of 10 seconds.
