Waste-to-Energy Equipment worked example
Weldment Cost at 99% first-pass acceptance: a worked example
This scenario runs the weldment cost calculation on the strong side: 99% first-pass acceptance, with every other input held at its documented default. Used by fabrication estimators to price welded boiler, duct, and pressure-part assemblies for a waste-to-energy build.
The inputs for this scenario
- Deposited Weld Length: 1,800 in (unchanged)
- Welding Cost per Inch: 22 $/in (unchanged)
- First-Pass Acceptance: 99 % (raised for this scenario; the documented default is 90)
- Fit-Up & NDE Setup: 3,800 $ (unchanged)
Working through the calculation
- Applying the documented formula (Cost = weld length x welding cost per inch x acceptance % + fit-up & NDE setup) to the inputs above produces each figure below.
- At this operating point the engine returns 43,004 $ for total weldment cost, the number this scenario is built around.
- At this operating point the engine returns 23.89 $ / piece for weldment cost per unit.
- At this operating point the engine returns 39,204 $ for variable weldment cost.
- At this operating point the engine returns 3,800 $ for fixed weldment cost adder.
How this compares with the baseline
- Against the tool's baseline example, where first-pass acceptance sits at 90% and the headline result is 39,440 $, this scenario comes in 9.04% above the baseline at 43,004 $.
- Use it when quoting welded WtE fabrication or when diagnosing why a weld-heavy assembly is over budget. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
