GSE Weldment Scrap Cost at 47% scrap exposure share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop scrap exposure share to 47%, then walk the calculation through step by step. Estimate scrap cost for GSE frames, tow bars, lift structures, and stands from scrapped weldments, cost per weldment, scrap exposure share, and fixed rework cost.

The inputs for this scenario

  • Scrapped GSE weldments: 28 weldments (held at the documented default)
  • Cost per GSE weldment: 1,850 $ / weldment (held at the documented default)
  • Scrap exposure share: 47 % (the input this scenario stresses; the baseline uses 65)
  • Fixed inspection or disposal cost: 9,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable weldment scrap cost = scrapped GSE weldments × cost per weldment × scrap exposure share.
  • Total GSE weldment scrap cost works out to 33,346 $ scrap cost at these inputs, and this is the headline figure for the scenario.
  • Cost per GSE weldment works out to 1,191 $ / piece at these inputs.
  • Variable weldment scrap cost works out to 24,346 $ at these inputs.
  • Fixed inspection or disposal cost works out to 9,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where scrap exposure share sits at 65% and the headline result is 42,670 $ scrap cost, this scenario comes in 21.85% below the baseline at 33,346 $ scrap cost.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to scrap exposure share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The exposure share is a single blended factor, so it will not separate scrap caused by material defects from scrap caused by welder or fixturing error.

Results at a glance

  • Total GSE weldment scrap cost: 33,346 $ scrap cost (headline result)
