Hi all,
First post in a very long time on a new account - lost my old login.
AMS-A-22771 calls out "4.4.5 Prior to penetrant inspection, each forging shall be etched (See 4.4.4), dried (See 4.4.4), and penetrant inspected (See 4.3.2.1.2) in accordance with ASTM E 1417". ASTM E 1417 indicates that "3.8 Examination Sequence - Final penetrant examination shall be performed after the completion of all operations that could cause surface-connected discontinuities or operations that could expose discontinuities not previously open to the surface. Such operations include, but are not limited to, grinding, welding, straightening, machining, and heat treating."
Ultimately, one division of my company makes the forging and another machines the forging to shape. Whose responsibility is the penetrant inspection? There's a bit of an internal debate over if AMS-A-22771 intends the forging to be penetrant inspected, or if the final machined part should be, and I'm looking for insight.
Thanks!
