Not wanting to debate FAA rules.. they are what they are. My post was that the FAA RECOMMENDED post TiG weld tempering.
AMT Handbook 2012:
"However, do not eliminate the postweld heat
treatment as doing so could severely limit the fatigue life of
the weldment due to the formed martensitic grain structure."
Even Gas welds are to be tempered:
"When the weld is complete and still in the red heat,
circle the outer envelope of the torch around the entire
weldment to bring it evenly to a dull red. Slowly back
the torch away from the weldment to ensure a slow
cooling rate."
If it ain't in the log book, it didn't happen.
