extensive testing by such manufacturers as Brown-Boveri. If a partic-
ular operating condition exceeds the limits for a solid rotor, then
welded rotors are employed (see Sec. 5.3). Figure 5.5 depicts an approx-
imation of stresses set up in the rotor as a function of diameter and
start-up procedure.
