NDT Master: UT Calculator

AWS D-Rating, DAC/TCG curves, 3D beam simulation, OCR capture, and 9 UT calculators for field weld inspection. Offline, on-device.

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.

Offline and private

• Built for Real Field Work: Local data, no account, offline-first workflow
