What should count as dimensional acceptance after welding?

We're planning planning repeatable welding of bracket assemblies with Fairino FR10 on a fabricated gusseted mounting bracket in a welded-bracket fabrication workshop. Our old inspection notes say it looks aligned while restrained, then falls outside the drawing requirement after release. I want to untangle fit-up, fixture location and final inspection before our new cell inherits an unexplained correction routine. This is a records review, not live welding adjustment.

@BrunoBell0626 Compare the specified inspection condition and reference supports with the historical sheets. Do individual measurements identify whether the assembly was restrained or released?

The sheets mix clamped checks and released measurements. Some don't say which. The drawing has the dimension, but our procedure leaves the support condition vague.

Have quality and the drawing owner define the acceptance condition. Group the old results by known measurement state; that should make them comparable.

@AnikaAllen0334 Same restraint label still doesn't mean comparable. Unknown supports and mixed fixture or process revisions could remain inside those groups.

@HazelAli0223 You're right; I overstated that. Grouping exposes one difference. Keep support conditions, fixture revision and process links visible too, including anything unknown.

@AnikaAllen0334 Would you leave an empty fixture-revision field, even if someone remembers which one was probably used? That's already becoming an argument here.

Mark it unknown. You can note the recollection separately as something to investigate, but don't turn a probable revision into a recorded fact.

I had a separate bracket job where inferred fixture revisions created an apparent trend. Once the original sheets established the revisions, the trend no longer held.
