QA/QC & Production Calculators
Fast calculation tools for welding quality, NDT sampling, hydrotest planning, calibration dates, manpower productivity and fabrication output. Built for preliminary planning and reporting—not as a substitute for approved procedures or project specifications.
QA/QC calculations
NDT Sampling Quantity
Rounds upward to a whole joint. Apply the project specification for selection/distribution of joints and any additional examination rules.
Weld Repair / Rejection Rate
Use a consistent project definition when trending repair or rejection rates.
Hydrotest Reference Pressure
Do not assume 1.5 is correct for every system. Enter only the multiplier required by the applicable code/project test procedure and account for elevation, component ratings and temperature where required.
Calibration / Inspection Due Date
Actual calibration validity is governed by your QMS, manufacturer requirements and project/client rules.
Productivity & fabrication calculations
Man-Hours & Productivity
Welding Inch-Dia
Inch-dia is a production/estimating convention. Define the project measurement rule consistently, especially for branches, fittings and non-circumferential welds.
Fabrication Output vs Target
Resource Requirement
Use demonstrated site productivity where available; actual crew composition, access, permits, logistics and supervision can materially change output.
Use results with project controls
QA/QC and production numbers become more useful when they are trended: weld rejection rate by welder/process, planned versus actual output by period, man-hours per unit and remaining-resource forecasts. Consistent definitions matter more than a single isolated result.
