How do you calculate GSE weldment scrap cost?

Multiply scrapped weldments by cost per weldment by the scrap exposure share for the variable loss, then add fixed inspection or disposal cost. Here 28 weldments at $1,850 with a 65% exposure share give $33,670 variable, plus $9,000 fixed, for $42,670 total.

What does the scrap exposure share represent?

It is the fraction of full weldment value actually lost. Salvaged material, partial rework credit or reusable fittings mean you rarely lose 100%; the 65% share here reflects that some value is recovered from each scrapped unit.

Why include a fixed cost separately?

Costs like NDT re-inspection sweeps, hazardous disposal fees or fixed lab charges do not scale with the number of scrapped weldments, so they are added as a flat amount. In the example they contribute $9,000 of the $42,670 total.

What is a good weldment scrap level for GSE fabrication?

There is no universal target, but weld scrap eroding tens of thousands of dollars a period, like the $42,670 here, usually justifies a root-cause project on fixturing, fit-up or welder qualification.

How do I bring weldment scrap cost down?

Attack the biggest lever: reduce the number scrapped through better fit-up and weld procedure control, or lower exposure share by recovering more material from rejected units. Fixed inspection or disposal cost falls only by changing the process that triggers it.

Variable vs total scrap cost, which should I report?

Report total for budgeting and the business case, since it includes the $9,000 fixed overhead, but track variable cost ($33,670 here) when measuring the impact of weld-quality improvements that act on the per-unit loss.

Airport Ground Support Equipment calculator

GSE Weldment Scrap Cost Calculator

GSE Weldment Scrap Cost puts a dollar figure on the fabricated structures, tow bar frames, dolly chassis, GPU enclosures and tug subframes, that fail weld inspection or get rejected and have to be written off. Ground support equipment is weld-heavy and safety-relevant, so a cracked or porous weldment is not reworkable scrap you can shrug off; it carries material, labor and often fixed inspection or disposal overhead. Fabrication managers and quality engineers use this calculator to quantify what weld scrap actually costs per period, separating the variable per-unit loss from fixed costs like NDT re-inspection or hazardous disposal. The number is what turns a vague weld-quality complaint into a funded improvement project.

What this calculator does

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.
a fabrication manager needs to estimate weldment scrap exposure for airport GSE structures
It computes total weldment scrap cost by combining variable per-weldment loss, scaled by an exposure share, with a fixed inspection or disposal cost.

Formula used

Variable weldment scrap cost = scrapped GSE weldments × cost per weldment × scrap exposure share
Total weldment scrap cost = variable scrap cost + fixed inspection or disposal cost

Inputs explained

Scrapped GSE weldments:
Cost per GSE weldment:
Scrap exposure share:
Fixed inspection or disposal cost:

How to use the result

Use it when costing weld scrap for a period, building a business case for a fabrication quality improvement, or comparing scrap across weld cells.
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.

Current U.S. benchmarks

Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
