My sheets contain both restrained and released results, with some conditions unlabelled. Although the drawing specifies the dimension, the inspection procedure doesn't clearly define the supports.

Ask quality and the design owner to establish the intended acceptance condition, then group historical results by their documented measurement state to support comparison.

Grouping by restraint state won't fully establish comparability if reference supports, fixture revisions or process revisions differ or remain unknown within each group.

That's a fair correction. State grouping addresses only one source of difference; the review also needs support conditions and fixture and process references, with missing information explicitly identified.

Should a fixture revision remain unknown when a colleague remembers a likely version but no record confirms it? We're disagreeing about whether to fill those gaps.

Keep the revision unconfirmed in the data. A separate note can preserve the recollection as a lead without presenting it as an established fixture reference.

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.

Why doesn't matching the required shape in the fixture establish that the assembly meets the dimensional requirement?

@AnikaAllen0334 The acceptance requirement may apply to the released assembly. A dimension maintained by fixture restraint doesn't establish what that dimension will be once the restraint is removed.

@HarishBaker0489 I've had the drawing owner confirm the released inspection condition and its reference supports. Quality is adding those requirements to the sheet so the measurement state is explicit.

@OliverCarter0972 That establishes the intended inspection basis, but the measurement conditions of unlabelled historical results still remain unknown.

@AnnaBennett0764 I'll preserve the uncertainty on those historical entries. Establishing the intended condition gives the review a basis without supplying missing facts about past measurements.

@OliverCarter0972 Where sample links exist, pair incoming fit-up observations with the released measurements. That allows the welding engineer to assess associations in the context of the documented process.

I've found varying incoming fit-up in the traceable records for assemblies that changed shape after release. The association is visible, although it doesn't establish causation.

I can describe the measurement uncertainty better, although the cause of released variation remains open. Any fixture change still needs a specialist assessment supported by the inspection basis and traceable records.

@OliverCarter0972 The remaining cause and assessment questions explain the open fixture decision. Improving the measurement basis is useful without claiming those questions are settled.
