my point is in new TTS qualification, do we need to consider final expansion after welding or just do the welding and proceed for destructive analysis. ASME IX is not specific about this point, however, it added expansion as essential variable in case it is required prior to welding.

i have seen many manufacturers just doing the welding and proceed for destructive analysis, however, i would like to check the best practices and recommend approach.

i believe doing the expansion after welding prior to sectioning the mockup would be better in terms of simulating the production process.

any idea?

thanks
 
ASME IX is clear
The test is performed with expansion and weld completed.
