Master UT Training Anytime: Introducing the Free Ultrasonic Testing Simulator

At Ironhand Welding, we know how important it is for welders, inspectors, and students to get hands-on practice with ultrasonic testing (UT). Real equipment and training pieces can be costly, and it’s not always easy to access them when you need to study. That’s why we built the Ultrasonic Testing Simulator—a free, browser-based training tool now available right here on ironhandwelding.org.

Why This Simulator Matters

Ultrasonic testing is one of the most powerful methods for detecting weld defects, but it’s also one of the most challenging to master. Trainees often struggle with:

• Understanding beam behavior inside metal parts

• Learning how machine settings like gain, range, delay, and angle affect the A-scan display

• Recognizing real-world defect echoes and distinguishing them from backwall reflections

Our simulator provides a safe, cost-free way to explore these concepts interactively—perfect for students preparing for certification, instructors supplementing classroom teaching, or professionals refreshing their knowledge.

Key Features

• 🎛️ Adjustable UT machine settings – Practice with gain, range, delay, velocity, and angle.

• 📡 Probe control – Move and flip the probe, watch beams bounce, and visualize how angles change the signal.

• 🧱 Multiple test parts – Switch between different weld joints and plate setups to see how defects behave.

• 🔦 Defect visibility toggle – Hide or show defect positions to test yourself.

• 📈 Realistic A-scan display – View backwall echoes, defect signals, and gate triggers just like on real equipment.

• 📉 DAC curve & gate overlays – Learn how reference levels and gates affect signal interpretation.

• 💻 Web-based & free – No software to install; runs directly in your browser.

Benefits for Learners and Instructors

• Accessible – Train anywhere with only a computer and internet connection.

• Cost-effective – No need for expensive UT machines or calibration blocks.

• Self-paced – Explore settings and part geometries at your own speed.

• Instructional support – Teachers can use it to demonstrate beam paths and echoes live in class.
