Ultrasonic Testing (UT) or Flaw Detection is a highly effective NDT method designed primarily for detecting internal flaws within materials. While it can identify both surface and subsurface flaws using angle beam probes, it excels at uncovering hidden internal defects like cracks, shrinkage, blow holes, lack of fusion, and slag inclusions.
 

This method finds its applications in testing various materials, including castings, forgings, plates, and welds. It is versatile enough to be applied to a wide range of materials, encompassing both metals and nonmetals such as ceramics, plastics, and composites. Essentially, any material capable of conducting ultrasonic sound can be subjected to UT testing, making it an incredibly versatile tool with minimal material limitations.

Ultrasonic testing has evolved significantly, moving beyond basic techniques involving single or T-R probes. Advanced methods like Phase Array and TOFD, which employ multiple crystals, have extended its utility, particularly in weld inspections where they offer broader applications.

In terms of safety and cost-effectiveness, UT testing is gradually supplanting Radiography or X-ray for weld inspections, providing a more efficient and reliable alternative.

It’s important to note that while humans can hear sounds in the range of 20Hz to 20KHz, UT testing employs high-frequency sound waves exceeding 20,000 Hz. Mechanical applications typically operate within the frequency range of 0.5MHz to 10MHz, while aerospace and other critical applications may require frequencies ranging from 10MHz to 25MHz. The choice of frequency depends on the desired sensitivity and the need to detect smaller flaws, with higher frequencies enabling finer flaw detection.

Ultrasonic inspection is a powerful technique for detecting internal volumetric flaws. Applied to wide range of materials, including ingots, castings, forgings, rolled plates, and welds. This method proves effective for testing raw materials, monitoring in-process components, and inspecting finished materials. UT can be employed for in-service inspections, allowing the detection of fatigue cracks, measurement of wall thickness, and estimation of corrosion damages.

When it comes to measuring wall thickness, Digital Ultrasonic Thickness Gauging (UTG) offers exceptional precision for chimneys, boiler pipes, tubes, tanks, and pressure vessels. Over the last two decades, UTG has become the preferred method, replacing traditional thickness gauging techniques for chimneys and boiler pipes. Its accuracy is unrivaled, with the ability to achieve measurements as precise as 0.001mm.

It’s important to note that the ultrasonic method may not detect cracks and flaws that run parallel to the beam, particularly those originating from the surface. For such surface-related cracks, alternative methods like Dye Penetrant Testing(PT)Magnetic Particle Testing(MT), or Eddy Current Testing(ET) are recommended.

Best practice often involves the use of both surface and internal NDT methods. Combining techniques like PT, MT, or ET for surface inspection with UT or RT for internal inspections enhances the overall detectability of flaws. This comprehensive approach ensures a higher level of quality control.

Experienced Inspectors for Weld Ultrasonic Inspection

Welding is a process of joining metals permanently using heat and/or pressure. As per AWS, there are 5 types of weld joints. Butt, fillet, lap, corner and edge joints. Of these, butt weld joints are suitable for Ultrasonic testing.Whereas others are less effective to perform the testing.

Shear wave, angle beam ultrasonic scanning can detect lack of fusion, lack of penetration, slag and deep lying flaws. All welds and surfaces up to probe travel distance (called skip distance)are cleaned. This enables the probe to travel on the base metal surface smoothly. UT Inspectors will calculate skip distance and beam path distance using  UT formulae. He/she will perform, record, interpret and evaluate the welds for acceptance.

A team of NDT Level 2 technicians have all the skills needed for weld inspections. Experience in performing test under third party inspection. An NDT Level 3 from ASNT, for approving the results. Therefore, customers and third party agencies prefer us for our expertise in Weld Ultrasonic inspection as per ASME, AWS, EN and ISO codes and standards. Check the UT procedure and free download.

Ultrasonic thickness testing stands out as a highly effective NDT method for precisely measuring the wall thickness of various components, including pipes, tubes, boiler components, and chimneys. UT machines excel at providing accurate measurements, with digital thickness gauging machines capable of achieving accuracy levels as fine as 0.1mm or even less. Probes designed for highly absorptive materials utilize lower frequencies and larger diameters to ensure optimal performance.

Notably, UT probes are not limited to room temperature applications; specialized probes are available for high-temperature scenarios, such as boiler and heat exchanger tube inspections during in-service maintenance. These probes are complemented by special high-temperature couplants, such as Silicone grease, which are suitable for elevated temperature environments.
