- Match probe frequency/angle to the weld geometry
- Use fresh couplant and reapply often on hot or rough surfaces
- Scan in multiple directions to rule out geometry echoes
- If signal is unstable, re-check wedge wear and cable connections
- Always compare suspect signals to calibration block responses
