Our weldment looks aligned until it comes out of the fixture

We're planning reviewing fixtures for welded mounting brackets with Universal Robots UR5e on a gusseted steel support bracket weldment in a precision fabrication quality department. 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.

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

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.

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

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.
