Welding — NDT Budget
Inspection-hours budget from weld counts and per-weld NDT times.
UT on full-pen welds, MT on fatigue details, VT on everything — inspection hours scale with WELD COUNT, not tonnage. Designs that swap many small welds for fewer larger ones quietly cut this budget.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Welding — NDT Budget
Welding — NDT Budget computes the governing relationship hours = Σ(count×minutes)/60 live as you type. UT on full-pen welds, MT on fatigue details, VT on everything — inspection hours scale with WELD COUNT, not tonnage. Designs that swap many small welds for fewer larger ones quietly cut this budget. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Welding — NDT Budget
