Abstract
The cams (2) of the inventive camshaft, which is configured from an assembly of individual parts, are provided with foot strips (2.2, 2.3) that border the shaft (1). Said cams are welded to the shaft along and through these foot strips. This produces a weld joint (3.1) with a virtually optimal weld cross-section (3.1), whose width corresponds approximately to the width of the foot strips and thus produces an extremely good joint overall which is strong and permanent. As the shaft and the cams are put under only minimal strain by the welding process, they can be machined almost to their final dimensions before being assembled. The cams can be welded efficiently to the shaft in one single time-saving work operation.
