Weld Inspection Cost with weldments inspected of 250 parts: a worked example

Push weldments inspected up to 250 parts and the picture changes. This example computes every intermediate figure at that operating point. Use it when quoting NDT, visual, or CWI inspection on a weld run and you need to load the cost of inspection into the per-part price.

The inputs for this scenario

  • Weldments inspected: 250 parts (raised for this scenario; the documented default is 100)
  • Per-part inspection cost: 15 $ / part (unchanged)
  • NDT or CWI setup cost: 275 $ (unchanged)
  • Inspection reporting and burden: 180 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total weld inspection cost = weldments inspected × per-part inspection cost + NDT or CWI setup cost + inspection reporting and burden) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,205 $ for total weld inspection cost, the number this scenario is built around.
  • At this operating point the engine returns 16.82 $ / piece for weld inspection cost per part.
  • At this operating point the engine returns 3,750 $ for per-part inspection cost.
  • At this operating point the engine returns 455 $ for ndt setup and reporting.

How this compares with the baseline

  • Against the tool's baseline example, where weldments inspected sits at 100 parts and the headline result is 1,955 $, this scenario comes in 115% above the baseline at 4,205 $.
  • It sums per-part inspection cost, NDT or CWI setup, and reporting/burden into a total, then divides by weldments inspected for a per-part cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total weld inspection cost: 4,205 $ (headline result)
  • Weld inspection cost per part: 16.82 $ / piece
  • Per-part inspection cost: 3,750 $
  • NDT setup and reporting: 455 $
