A.19.CN:8.1 - Industrial line — Weld‑quality CN‑frame (AssemblyLine_2026)

  • cs_basis: BeadWidth[mm] (target 6.0±0.2), Porosity[ppm] (↓), SeamRate[1/min] (↑ until limit)
  • chart: reference jig, fixture ID, torch type; MethodDescription#Weld_MIG_v3
  • normalization: affine rescale on gray‑level calibration → invariant = physical porosity
  • comparability: normalization‑based (UNM) (calibration tables applied)
  • aggregation: a minimum bound only for a declared bottleneck quality model; commutative count addition only for disjoint contributions; time = per-shift histograms
  • RSG hook: WelderRole.Ready requires Porosity ≤ 500 ppm & BeadWidth within ±0.2 mm admitted by this CN‑frame.
