Abstract
The invention relates to a method for producing cams ( 1 ) for a camshaft. The cams are produced by bending together the ends of long profile strips ( 4 ) or by bending and putting together several pieces of profile strips in a circumferential direction. Cams produced in such a way are preferably welded onto the shaft. The invention also relates to suitable welding methods such as resistance welding, laser-beam or electron-beam welding and corresponding devices.
