NDT Wizard

NDT Wizard is the field reference every NDT inspector wishes they'd had on the tools.

The calculators you actually use, a guide to the weld acceptance standards, interpretation help and a UT simulator — all in one clean app that works with no signal, anywhere on site.

By technicians, for technicians.

⚙️ NDT CALCULATORS

Wavelength · near field · Snell's law & critical angles · beam spread · time of flight · dB/gain · skip & sound path · attenuation · PAUT aperture, focal laws & grating lobes · TOFD PCS, dead zones & depth · RT exposure, source decay, IQI & HVL · eddy-current skin depth · unit converter. Numbers you can trust — every formula checked.

🧰 AUT BAND RISER CONFIGURATOR

Set up CRC-type AUT scanner bands fast — work out the riser heights you need when the band size differs from the pipe OD, with suggested slot counts.

📋 WELD ACCEPTANCE — YOUR GUIDE TO 8 STANDARDS

Know which standard, clause and table applies, and how each one's acceptance works: ISO 5817 · ISO 10675 · ISO 11666 · ISO 10863 · DNV-ST-F101 (Appendix E AUT) · ASME B31.3 · ASME VIII · API 1104. Plus an indicative flaw checker. NDT Wizard points you to the criteria — always read the values from the standard itself.

🔬 UT SIMULATOR

A-scan echo prediction with a DGS-style amplitude model, beam-section view, near-zone shading and back-wall shadowing — see how a defect changes the trace.

🧭 INTERPRETATION GUIDES

AUT strip-chart reading · DNV-ST-F101 AUT methodology · AUT indications by through-wall location · PAUT flaw characterisation · TOFD · MPI · PT · RT · eddy current.

📚 REFERENCE LIBRARY

Defect library · weld prep & bevel geometry · material velocity tables · NDT glossary · covered standards — with fast search.

📷 YOUR OWN DEFECT IMAGES

Build your own reference — capture defect and scan images with the camera or add them from your photo library, kept alongside the built-in defect library for future recall. Images stay on your device.

🎓 CERTIFICATE & TICKET TRACKER

Log your NDT certifications and site tickets with their expiry dates and get reminders before they lapse (180 / 90 / 30 / 14 days before) — so an expired ticket never catches you out on site.

📡 WORKS OFFLINE

No signal offshore, in a tank, or down a trench? No problem. Everything runs on-device. Nothing to load, nothing to wait for.
