## Description

ASNT/ASME-ready UT calculations with real-time 3D beam simulation, OCR value capture, and full offline workflow. All data stays on-device, no account required.

NDT Master is built for field ultrasonic testing workflows. It brings AWS D-Rating, DAC/TCG curve building, 3D beam simulation, OCR parameter capture, and practical UT calculators into one offline-first app.

Core field workflows
- AWS D-Rating in 5 Seconds: Fast weld indication workflow for field UT
- Build DAC/TCG Curves Fast: Plot reference echoes and gain table instantly
- Scan Readings. Auto-Fill Parameters.: OCR maps velocity, MHz and dB in seconds
- Locate Flaws Faster: Instant depth and projection outputs
- Critical Angles at a Glance: Snell + beam spread for setup confidence
- Beam Spread You Can Trust: Visualize setup impact before inspection starts

Tools included
- 9 UT calculators: Wavelength, Near Field, Beam Spread, Flaw Location, Snell's Law, ToFD PCS, dB Calc, Acoustic Impedance, Resonance.
- Material presets for steel, aluminum, stainless steel, and common inspection setup.
- Code-aware workflows for weld inspection decisions, with AWS and ASME terminology kept visible.
