A ROLLING DEVICE FOR UNRESTRICTED WELDING OF STATOR FRAMES BY CONVERTING THE WELDING FROM 5G POSITION TO 1G POSITION

摘要

The invention relates to a rolling device for unrestricted welding of stator frames by converting the welding from 5G, 4G, 3G position to 1G position, comprising at least a pair of metal rings (2), each ring (2) disposed at proximal and distal end of a stator frame (3) of a turbogenerator; at least two pairs of pipe members (1), each pair (1) is weldably joining the ring to the stator frame (3); a pair of roller (4), each controllably rotatable by an electrical motor, each roller (4) being attachable to the subassembly of the ring and pipe member (1,2) such that the entire assembly of the stator frame (3), ring (2), and the pipe (1) can be rotated based on simultaneous measurement of the centre line of the stator frame (3).
