After welding and post weld heat treating a test plate at 1150 deg F the mechanical tests were performed. It it necessary to perform additional testing to cover subsequent solution anneal and hardening performed at various temperatures depending on the use?
Depends on a number of factors; are you trying to qualify to ASME IX? Are there constructing codes or specifications involved? Your question is good, but we need a bit more information to give a good answer.
