Plant managers rarely get budget for better inspection, they get budget for lower cost, and weld quality hides some of the biggest cost lines in the building. Rework loops, containment, warranty exposure and slow PPAP cycles each look like a separate problem, which is why no single line item seems large enough to justify new technology. Stacked together, though, they form a business case that finance can test with the plant's own numbers instead of vendor claims. To build that case with your own scrap, rework and approval data, work through the model line by line with an iFactory specialist.
Automotive Weld Quality ROI Model for Plant Managers
Stack avoided rework, lower warranty exposure and faster PPAP cycles into one defensible number your finance team can challenge and approve.
Three Value Streams That Build Into One Net Number
Each stream is modest alone, but together they climb past the program cost faster than most teams expect.
Bar heights are illustrative only, because every plant's figures differ.
Pricing the Welds You Fix Twice
Use your own repair-station counts for A and B, and keep C conservative until a shadow-mode trial shows the real number.

iFactory can pre-load your rework and scrap history so the first value estimate comes from your data, not an average.
Why a Weld Escape Gets More Expensive at Every Step
Warranty value is hard to promise and easy to overlook, so treat it as upside until your claims history supports a figure.

What Your Finance Team Will Ask You to Source
| Input | Where to Find It | Usual Owner | Confidence Needed |
|---|---|---|---|
| Rework volume | Repair station logs, MES defect codes | Quality lead | High |
| Cost per rework | Labor rates, consumables, line downtime | Plant finance | High |
| Escape history | Customer returns, containment records | Quality manager | Medium |
| PPAP effort | Past launch timelines and engineering hours | Launch manager | Medium |
| Program cost | Software, integration, training | Plant manager | High |
