I'm reviewing historical records for our planned planning repeatable welding of bracket assemblies with Fairino FR5 and a gusseted steel support bracket weldment in a precision fabrication quality department.
The notes describe alignment under restraint but dimensions outside the drawing requirement after release.
I'd like to distinguish incoming fit-up, fixture location and final acceptance before carrying an unexplained correction routine into the new cell; no live welding adjustments are involved.
@SamBrooks0855 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.
Have quality and the drawing owner define the acceptance condition. Group the old results by known measurement state; that should make them comparable.
Grouping by restraint state won't fully establish comparability if reference supports, fixture revisions or process revisions differ or remain unknown within each group.
You're right; I overstated that. Grouping exposes one difference. Keep support conditions, fixture revision and process links visible too, including anything unknown.
@RaviAbbott0041 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.
Because the required inspection condition may be after release. Holding a shape under restraint doesn't establish the shape the assembly takes without that restraint.
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.
My review approach is settled: establish the acceptance condition and use measurements with identifiable conditions.
I can take that forward while leaving fixture and process changes dependent on specialist assessment.
