The device comprises a robot (20) with a jointed arm (21) mounting the electric welding device (14). Arranged within reach of the jointed arm (21) is an unbalance measuring station (1) for measuring the amount of unbalance of the rotor (2) with an electronic computer which computes a corrective weight (15) to be attached to the rotor (2) for unbalance correction and transmits control data to a control device (23) of the robot (20). Under robot control, the welding device (14) picks the computed corrective weight (15) from a magazine (27) arranged within reach of the jointed arm (21) and welds it to the rotor (2) in the unbalance measuring station (1). During the welding operation the rotor (2) takes support on a first supporting device (11) and the welding device (14) on a second supporting device (12).
