ABSTRACT:
A method for axially aligning adjacent opposing faces of a first and second shaft segment having a respective joint face, of a steam turbine rotor to be welded together includes mating the joint faces of each shaft segment, placing a crushable lip, which axially extends from one of the joint faces, under an axially compressive force, and supporting the joined shaft segments at their axially outboard ends. An apparatus for axially aligning opposing end faces of a first and second shaft segment to be welded together, the first and second shaft segments including a respective joint face. An adjustable support for raising and lowering the joined shaft segments thereby changing the axial distance across the annular groove defined by adjacent opposing end faces to be welded. Means for measuring the force at the adjustable support, provides an indication of the weight counteracted by the support when optimum axial alignment of the shaft segments is achieved. Heating regions proximate adjacent opposing end faces and welding adjacent end faces together are accomplished while maintaining optimum axial alignment of the shaft segments.
