ABSTRACT:
A mask is provided for shielding a radially extending edge of an impeller vane during a weld repair process, where the impeller vane extends radially and axially outwardly from a shaft. The mask comprises a hub and a flange. The hub has an outer surface and an opening extending therethrough, and the opening is configured to allow the shaft to extend at least partially therethrough. The flange extends radially outwardly from the hub outer surface and is configured to shroud substantially all of the impeller vane radially extending edge.
