About this app

Welcome to the Non-Destructive Testing (NDT) educational app, a structured learning companion and technical reference for material inspection, defect detection, quality control, and NDT engineering. It is designed for technicians, engineering students, inspectors, and professionals who want to understand testing methods, calculations, standards, and practical workflows without damaging materials.

📱 THREE-PART LEARNING STRUCTURE
1. LEARN TAB
Explore lessons covering NDT fundamentals, terminology, applications, safety, standards, and major inspection methods.

2. TOOLS TAB
Use calculators and references related to material properties, ultrasonic testing, radiographic testing, magnetic testing, penetrant testing, and electromagnetic inspection.

3. HOW-TO TAB
Follow step-by-step guides explaining method selection, material preparation, testing procedures, and NDT standards.

📚 NDT LEARNING TOPICS
• Fundamentals and Standards
Understand the purpose, benefits, terminology, history and applications of NDT, along with standards such as ASTM, ASME, ISO, ASNT, and EN.

• Visual Testing
Learn how direct inspection and optical aids help identify visible defects, corrosion, misalignment, and workmanship issues.

• Liquid Penetrant Testing
Study surface defect detection using penetrants, dwell time, developers, cleaners, emulsifiers, and inspection procedures.

• Magnetic Particle Testing
Understand how magnetic fields and particles locate surface and near-surface discontinuities in ferromagnetic materials.

• Ultrasonic Testing
Explore sound wave propagation, time-of-flight measurements, thickness evaluation, flaw detection, attenuation, beam paths, calibration, and automated inspection.

• Radiographic and Electromagnetic Methods
Study radiation inspection, image quality, geometric unsharpness, exposure, eddy current concepts, skin depth, coil behaviour, and frequency selection.

• Industrial Applications
Understand NDT applications in pipelines, pressure vessels, boilers, welds, oil and gas systems, manufacturing, aerospace, and maintenance.

• Advanced Technologies
Explore guided waves, ground-penetrating radar, robotics, laser inspection, microwave testing, and digital inspection methods.

🛠️ ENGINEERING CALCULATORS AND TOOLS
The Tools section includes material property references, hardness and unit conversions, penetrant dwell time, magnetizing current, flux density, ultrasonic velocity, thickness, attenuation, beam path, near-field length, dead-zone estimation, calibration blocks, radiation exposure, safety dose, half-value layer, source decay, geometric unsharpness, film density, eddy current skin depth, coil impedance, frequency, wave velocity, event rate, load, and source location calculations.

📖 PRACTICAL HOW-TO GUIDES
Learn how to understand NDT principles, classify inspection methods, choose a suitable technique, prepare surfaces and materials, review safety requirements, follow workflows, and interpret common codes and standards.

🎯 WHO CAN USE THIS APP?
The app is suitable for NDT trainees, technicians, inspectors, quality professionals, engineering students, welding learners, maintenance personnel, and people working with materials and industrial inspection.

💡 LEARNING BENEFITS
Structured chapters make it easier to study NDT topics, revise key principles, compare inspection methods, and understand how calculations support testing decisions. Built-in tools offer a convenient way to practise evaluations and review engineering relationships.

The app can support academic learning, interview preparation, certification study, workplace reference, and general knowledge development.

🔄 REGULAR EDUCATIONAL UPDATES
The app receives general updates related to NDT learning materials, calculator improvements, topic organization, usability, performance, bug fixes, and stability. Updates may also refine existing explanations and improve the learning experience.

Ratings and reviews

Keeps sending notifications even though they are switched off. PLEASE STOP!!!!!!!!!!!!!!!!

Good app but the tables and charts are not easily readable so,please try to solve that problem other than that it's knowledgable please keep going on..

Very useful information for someone wanting to have a great resource for learning about NDE methods at any time. Well done!
