Welds per week
Fail % and repair % per week
Welds per month
First-pass yield % per month
Welder performance
Composite score 0–100: 40% repair rate + 35% NDE fail
rate + 25% productivity (welds/day welded vs the best eligible peer).
Rates at 0% score 100, at 10%+ score 0. Welders under 10 welds or 10
inspections are listed unscored. Flags mark rates over the 5% industry
line. Definitions: references/metrics_spec.md.
Welders
NDE by type
Report-level: every NDE report counts once (a weld shot
three times contributes three reports). Reject rate = rejecting reports /
reports of the type.
