Abstract
In a turbo engine's welded rotor includes a number of disks, the radially or quasi-radially extending welding seams are intermediately interrupted by annular cavities through which a cooling medium flows, and these cavities are surrounded by a circumferentially extending insert ring. This insures the flow of the cooling medium through the entire rotor without reducing the strength of the welding bond.
