Weld prep joint assembly with interference fit for electron beam or laser welding ; Method of welding such assembly

摘要

A weld prep joint (22) for welding a pair of axially aligned first and second machine rotor forgings (14,16) includes a first weld joint configuration in an end of the first rotor forging (14) including a first radial weld surface (26) and a first axial rabbet surface (28); a second weld joint configuration on an end of the second rotor forging (16) including a second radial weld surface (30) adapted to engage the first radial weld surface (26), a second axial rabbet surface (34) adapted to engage the first axial rabbet surface (28), and a third radial non-weld surface (33) extending radially inwardly of the second rabbet surface (34) and axially offset from the second radial weld surface (30). The present application further discloses a method of welding such pair of axially aligned first and second machine rotor forgings (14,16) through laser or electron beam.
