Abstract (en)
[origin: EP1895094A1] The turbo machine has a rotor rotatably supported within a housing, where the rotor is formed of two partial rotors that are welded with one another to form a welding area. A cover strap (6) and spin bores (12) are provided for cooling the welding area, and a guide vane row with guide vanes (7) formed with the cover straps. The cover strap is designed with the spin bores for guiding flowing medium, which flows through the turbo machine during operation on the welding area. One of the partial rotor is formed from a chrome material.
