<p>A method for inspecting a weld (25) joining a first rotor disk (10) made of nickel alloy and having an inner surface (12) and an outer surface (11) concentric with the rotor's longitudinal axis (LA) to a second rotor disk (15) comprising an inner surface (17) and an outer surface (16) concentric with the rotor's longitudinal axis (LA). The weld (25) made of nickel alloy fills a radial gap between the rotor disks (10,15), and has a dissimilar microstructure to either of the rotor disks (10,15), the method including the steps of; forming at least one slot (20) in the first rotor disk (10) extending through either the inner surface (12) or the outer surface (11) of the first rotor disk (10) terminating in the first rotor disk; and passing an inspection signal from the first slot (20), to the weld (25) so as to inspect the weld (25) for defects (27).</p> |
