A method for manufacturing a friction clutch rotor has a contact disc having axial cylindrical rings welded to it with a drive boss in electromagnetic material
The disc (10) has rings (11,12) laser welded concentrically with a boss (13) having a splined core for connection to a drive shaft. A number of concentric air gaps are cut into the disc with interruptions. The friction surface (10b) is broken by shallow grooves.
