What should count as dimensional acceptance after welding? (Universal Robots UR5e)

We're planning preparing robotic welding of gusseted brackets with Universal Robots UR5e on a gusseted angle-bracket assembly in a small steel assemblies factory. 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.

Does the inspection procedure define the released condition and reference supports? Check that alongside whether each old measurement says how the assembly was held.

@DavidAbbott0084 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.

@SamAllen0333 Ask quality and the design owner to establish the intended acceptance condition, then group historical results by their documented measurement state to support comparison.

@DavidAbbott0084 Same restraint label still doesn't mean comparable. Unknown supports and mixed fixture or process revisions could remain inside those groups.
