Pardon if this is a stupid question but we have requirements for surface indentations derived from D17.2 and the builder has exceeded the required indentations in a few places on 2mm SST sheet steel.  D17.2 doesn't provide any instructions for repair of excessive indentations.  Where is this defined or what is acceptable field practice?

I would first thing go to the engineer and ask for an EVA.

Acquiring an engineering variance on a few deep indents may be a lot less effort and risk than a repair if the part can be judged fit for purpose.

Sometimes just because a thing is out of tolerance does not demand something really should be done.

You might be extra persuasive if you have a corrective action plan in your pocket to give the engineer confidence it won't happen again.

Just an idea.

Also  D17 is pretty strictly a welding specification, so other fabrication tasks like riveting, drilling, bends, etc., and the tolerances that go with them are likely to be found in the OEM standard practice manuals rather than a welding specification.
