Ultrasonic & Phased Array Ultrasonic Inspection Services (UT & PAUT)
Advanced Non-Destructive Testing for Corrosion, Welds & Wall Thickness Measurement
Comprehensive Ultrasonic Testing (UT) Solutions Across Industries
Ultrasonic testing (UT) is a highly accurate non-destructive testing (NDT) method that uses high-frequency sound waves to detect internal flaws, measure wall thickness, and verify weld integrity. By transmitting ultrasonic waves into a test material, any reflected signals—called echoes—reveal discontinuities, defects, or corrosion below the surface.
At Advanced Turbine Support, our ultrasonic inspection services are trusted across industries including aerospace, energy, and manufacturing to ensure reliability, safety, and precision in every component we inspect.
Phased Array Ultrasonic Testing for Complex Geometries
Phased array ultrasonic testing (PAUT) provides a more advanced level of flaw detection and thickness measurement than conventional UT. By electronically steering multiple probes and transducers, our technicians can inspect complex geometries, welds, and pipes with unmatched accuracy.
Phased array UT inspection services deliver:
- High-resolution imaging and advanced flaw detection
- Full thickness measurement for erosion and corrosion mapping
- Rapid coverage of large components with precise size and location data
- Accurate defect detection without disassembly
This ultrasonic testing method provides immediate data visualization for reliable inspection and maintenance decisions.
How Ultrasonic Testing Works
During ultrasonic inspection, a transducer sends ultrasonic waves or sound waves into the test object. When these waves encounter a discontinuity, part of the wave energy reflects back to the transducer, while the rest continues through the material. The reflected signal’s amplitude and time delay reveal the size and location of the flaw or defect.
UT inspection is versatile—it can detect internal flaws, measure thickness, and assess weld quality without damaging the test material.
Pulse-Echo and Immersion Testing Techniques
Our team performs pulse-echo and immersion testing methods depending on the application.
- Pulse-Echo UT – Measures wall thickness and identifies internal defects by capturing echoes reflected from inside surfaces.
- Immersion Ultrasonic Testing – The test object is submerged in a liquid medium for consistent ultrasound coupling and improved signal clarity, ideal for composite and aerospace components.
These ultrasonic testing techniques provide precise detection of discontinuities, inclusions, and flaws across a wide range of materials and component types.
Weld Inspection and Thickness Measurement
UT weld inspection is an essential part of ensuring the structural integrity of joints, pipes, and assemblies. Using ultrasonic thickness measurement, our technicians can assess welds for flaws, lack of fusion, or porosity—without cutting, grinding, or removing the weld.
We also provide automated UT for repeatable, high-speed thickness scanning of turbine and piping systems. This nondestructive testing method allows for accurate corrosion detection and wall thickness profiling to extend component life.
