Eddyfi Phased Array Ultrasonic Testing Device TOPAZ64

Pipelines are essential for the operation of various industries such as water, oil, gas, and power generation, and maintaining pipelines in proper condition is a top priority in these fields. Since they are typically made of iron or steel, corrosion poses a significant threat to safety. Therefore, non-destructive testing for pipeline corrosion is necessary, and ultrasonic testing has been widely accepted as an ideal technology for detecting corrosion in pipelines. Phased array ultrasonic testing allows for accurate wall thickness measurements and can determine the presence of this invisible damage; however, it has been pointed out that there are issues with inspecting pipes along bend sections.

Friction stir welding is a solid-state joining method widely used in the aerospace industry. In the friction stir welding process, manufacturing parameters such as rotation speed and travel speed can lead to discontinuities at the joint, necessitating the application of non-destructive testing to verify the integrity of the joint. High productivity, work efficiency, and inspection accuracy are central to the quality assurance of newly manufactured aircraft.

Recent advancements in ultrasonic hardware and software have equipped almost all of our phased array ultrasonic testing devices with real-time full matrix capture and total focusing method. These represent a new generation of inspection technologies already defined in ASME and ISO standards. Austenitic stainless steel materials and dissimilar metal welds possess anisotropic coarse grain structures, resulting in specific behaviors of ultrasonic beams as they propagate through the material. This means high attenuation, high particle noise, beam redirection, and distortion; all of these phenomena ultimately lead to very challenging flaw detection conditions for phased array ultrasonic testing (PAUT). With the next generation of flaw detection equipment and high-performance probes offered by Eddyfi Technologies, we overcome challenges associated with inspecting high-difficulty materials such as dissimilar metal welds, including high ultrasonic attenuation, reduced signal-to-noise ratios, and insufficient coverage.
