# LMD Quality Evidence Ladder

Subtitle: What monitoring can show, and what inspection must prove.

The LMD Quality Evidence Ladder is a working framework for separating process observation, AI anomaly detection, inspection evidence, and final quality proof in Laser Metal Deposition.

## Important Messages

- Melt-pool monitoring is a process signal, not a certificate.
- AI anomaly detection is a risk indicator, not final proof.
- Inspection evidence must match the part risk and service conditions.
- AI is strongest when connected to physical validation.

## Levels

1. Visual process observation
2. Machine log and parameter record
3. Melt-pool image or process video
4. AI anomaly detection
5. Dimensional inspection
6. NDT: CT, UT, PT, MT
7. Metallography and hardness testing
8. Mechanical or functional testing
9. Field performance

## Use

Use this ladder when designing LMD monitoring workflows or RFQ evidence requirements.

## Disclaimer

Preliminary decision-support only. Final feasibility depends on base material, geometry, service conditions, inspection requirements, and expert review.
