METHOD FOR WELDING METALLIC BLADES

摘要

Rotating device comprising a blade (2) welded to a shroud (3), wherein : - said blade is provided with a profiled contact extremity (1), resulting in a reduced contact zone (6) able to contact the shroud; - said shroud is provided with a recess (4), the recess comprising a recess contact zone (5) surrounded by a lateral access zone (7), the area of the recess contact zone (5) of the shroud being adapted to the reduced contact zone (6) of the blade, the blade reduced contact zone contacting the shroud recess contact zone along a resulting contact zone (8); - filler metal is present along at least part of the resulting contact zone (8) and the blade is welded to the shroud along at least 10 % of the resulting contact zone.
