Ultrasonic testing (UT) performed in immersion tanks or using squirters or bubblers is an established non-destructive testing technology for automated inspection of wide variety of steel, aluminum, and composite assets. Ultrasonic immersion testing lends itself to high volume and/or surface area inspection applications that required high degrees of location accuracy, precision and repeatability of ultrasonic testing results. Immersion testing using automation robotics may

Introduction to Phased Array Testing of Composites Phased array ultrasonic testing (PAUT) of aerospace composites during the fabrication stage is an important quality control step to assure that composite structures do not contain delaminations, fiber Phased Array Inspection of Aerospace Compositesdefects, interlayer bonding issues, voids and ply cracking. Phased array testing of composites is comparably more challenging that testing metals due to the material anisotropy, hig

Streetlights, traffic signal lighting, traffic signage, and support beams are often installed and secured using steel anchor bolts embedded in steel rebar reinforced concrete. Depending on the age of the system, the condition of construction grade bolts and the footer may affect the load bearing capacity of the system. In some cases, damage may be incurred, and a fitness-for-service assessment is required. In many instances the design and fabrication specifications are unavai
