Two bracket checks with no common part identifier

I'm preparing fixture information for a UR5e welding review. An old jig sheet records alignment under restraint, and a separate inspection sheet records an angle after correction. They share a batch number but no individual part identifiers. I cannot tell whether they describe the same bracket, despite being stapled together.

Leave them as separate evidence. Stapling is not traceability, and guessing a before-and-after pair could send the new fixture design in the wrong direction.

I've separated them in the summary. Both use bracket revision H, but the first sheet names fixture J2 and the inspection sheet gives no fixture. I have asked quality whether another record connects them.

Do they have an untouched released-part result anywhere? That would be more useful than trying to reverse-engineer what the correction achieved.

Who is supposed to explain the correction to the new operators?

Good question. A missing method can turn into someone informally showing each shift a different trick. Eric, is the correction actually included in the proposed training?

No. Training currently covers the robot sequence only. I've raised the missing process explanation with the welding lead. Quality has found another final report, but still no measurement from before correction, so that gap remains.
