In a method for producing a spur-cut gear wheel, a plurality of individual components are provided with at least one hub, a disk wheel and a ring gear. The individual components are subjected to at least partial mechanical soft machining and joined by using a welding method. At least the ring gear is hardened and hard machined. Before carrying out a grinding burn test by using the nital etching process, gaps present on the rear side in the area of the welds produced during welding are sealed by using a sealing material that is resistant to nitric acid.
