Weld Scrap Cost with weldments scrapped of 10 parts: a worked example

This scenario runs the weld scrap cost calculation on the strong side: weldments scrapped of 10 parts, with every other input held at its documented default. Use it to put a dollar value on weldments that cannot be reworked and have to be cut up or sent to scrap.

The inputs for this scenario

  • Weldments scrapped: 10 parts (raised for this scenario; the documented default is 4)
  • Per-part sunk cost at scrap: 320 $ / part (unchanged)
  • Cutting and scrap disposal cost: 180 $ (unchanged)
  • Burden absorbed by scrapped lot: 240 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total weld scrap cost = weldments scrapped × per-part sunk cost at scrap + cutting and scrap disposal cost + burden absorbed by scrapped lot) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,620 $ for total weld scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 362 $ / piece for weld scrap cost per weldment.
  • At this operating point the engine returns 3,200 $ for per-part sunk cost at scrap.
  • At this operating point the engine returns 420 $ for disposal and absorbed burden.

How this compares with the baseline

  • Against the tool's baseline example, where weldments scrapped sits at 4 parts and the headline result is 1,700 $, this scenario comes in 113% above the baseline at 3,620 $.
  • Use it when a weldment fails inspection and cannot be reworked, or when weld distortion or burn-through renders a part unusable. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total weld scrap cost: 3,620 $ (headline result)
  • Weld scrap cost per weldment: 362 $ / piece
  • Per-part sunk cost at scrap: 3,200 $
  • Disposal and absorbed burden: 420 $
