Ultrasonic testing of steel and aluminum U.S. DOT cylinders is required to recertify the cylinders every 5 or 10 years depending on the cylinder type. Ultrasonic testing of DOT cylinders is currently performed with automated ultrasonic testing systems that uses wheel probes, squirter systems, or water jet systems. The ultrasonic immersion systems are configured with two circumferential shear wave channel, two axial shear wave channels, and one longitudinal straight beam prob

Aluminum Sensitization and Non-destructive Testing Aluminum alloy ship hulls are utilized on many commercial and military ship platforms. Over their lifetime, they often require non-destructive and destructive testing. Among the common hulls that require such examination include CG 47 Class Cruisers, Littoral Combat Ships (LCS) – both Freedom and Independence variants – as well as Amphibious Assault Ships, Expeditionary Fast Transport, Landing Craft Air Cushions, Ship-to

Introduction Non-destructive testing (NDT) of welds with phased array ultrasonic testing (PAUT) and more recently the total focusing method / full matrix capture (TFM/FMC) are two excellent techniques to detect, locate and size weld defects. Compared to ultrasonic weld testing, PAUT provides more efficient volumetric testing, increases weld defect probability of detection (POD), and should improve flaw sizing given the same NDT inspector skill level. The Total Focusing Method

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
