The invention relates to a method for producing an axle housing of a vehicle axle, by means of integrally connecting an axle tube () to an axle shaft () which is positioned on the longitudinal axis (L) of the axle tube, is equipped with bearing surfaces () for mounting a vehicle wheel, and has a tube cross-section facing said axle tube () which is substantially the same as the tube cross-section of the axle tube. In order to develop a welding method for the production of an axle housing that consists of an axle tube and an axle shaft secured thereto, which method is optimised in terms of the dynamic loads to which the axle housing is typically subjected in a driving operation, the method comprises the following steps: &#x2022;&#x2014;arranging the axle tube () and the axle shaft (), with the abutting surfaces of their tube cross-sections positioned coaxially to one another, in a workpiece receiving portion of a welding installation (), said welding installation additionally comprising an arc welding device () and a laser welding device () which is operated in parallel, &#x2022;&#x2014;continuously miming a weld seam () in the peripheral direction of the tube cross-sections, both welding devices () being directed, actively and from the outside, onto substantially the same peripheral section of the abutting surfaces, wherein the laser beam (S) meets the outside () of the tube at right angles, and intersects the longitudinal axis (L) of the axle tube (), and &#x2022;&#x2014;stopping running the weld seam () once this has passed over a peripheral angle of at least 360&#xb0;. A corresponding axle housing is also disclosed.

The invention relates to a chassis for a utility vehicle, having a firstchassis element extending transversely with respect to the vehicle longitudinal direction and a second chassis element () fixed to the outer side thereof, wherein the second chassis element () is supported against the outer side of the first chassis element via at least one roughened supporting area (). In order to avoid relative movements between the chassis elements connected by clamping forces in a utility vehicle chassis, the roughening comprises a surface structure produced by machining the supporting area () in a blasting process and preferably a laser beam process. The invention further relates to specific individual parts of such a chassis, specifically an axle shell, an axle guide (), and a brake carrier.
