One single mis step in the traceability and it became oart of a racing car or an artificial limb

Entirely understandable, one single defect could shatter a tiny turbine blade and potentially wreck an engine and the plane it was attached to.

Came as a bit of a shock in the earliest days when ball point oens were banned on site and if you needed to drill concrete you were given free diamond drill bits. Tungston is not popular in those places.

Blue pens...ALWAYS ude a blue pen.

NEVER sign a document in black.

Tungsten was under the specialty metals dept.

It has a higher melting point iirc, and will always persist as a defect, however many times you reprocess the material?

I just did the control systems. You want X Torr of vaccum, fine. Then want an inert gas backfill, fine. Then you want me to melt a 3 tonne welding rod into a crucible using a 50 volt power supply with a 20,000 amp capacity? Also fine.

We used microscopes to detect imperfections and there were always problems. I also did the uniformity surveys of ovens which had to be within +/- 3° throughout furnace area you could fit a dump truck in.

My retention records both live and archived could fill a library.

Don't ever get a Boeing audit.

I feel for the Quality team thats reviewing the latest crashes.

You could fill a pool with their sweat.

Oh well, DOGE teenagers are now going to fix it all for us

Sure, I'm sure they have their auditing degree somewhere.

Maybe from Trump University

Indeed

Shorter list, Timet, Rolls Royce and BaE Systems

My takeaway from it was traceability. A 3 tonne billet of titanium, remelted several times to ensure consistency, forged, cut and sent to another plant where it was rolled into plates. Then sent to RR who machined several tiny turbine blades from it, sending back the shavings which were smelted ....
