Abstract
A method for manufacturing a welded rotor of a fluid-flow machine are described, through which rotor a coiling medium flows through inflow and outflow passages inside the rotor and which is composed of a plurality of rotor disks, which are connected to one another by welds running radially or largely radially relative to the rotor axis and in each case enclose with one another a hollow passage, which runs around the rotor axis and interrupts the welds in such a way that a weld facing the rotor is directly adjacent to the hollow passage.
