About
Randika K.W. Vithanage is a leading researcher at the intersection of robotic automation, non-destructive evaluation (NDE), and advanced manufacturing. His work centers on developing sensor-enabled robotic systems for in-process inspection of critical industrial components, particularly in welding and additive manufacturing. Vithanage’s major contributions include the invention of a phased array ultrasound roller probe for automated, interpass inspection of multipass welds—a breakthrough that enables real-time defect detection during fabrication, reducing costly rework and production delays. His research on collaborative robotic systems for Wire + Arc Additive Manufacturing (WAAM) integrates ultrasonic NDE directly into the build process, a paradigm shift for quality assurance in metal 3D printing. With over 270 citations across his most-cited works, his impact is evident in fields ranging from railway maintenance to aerospace composites. Notably, his 2024 study applying machine learning to ultrasonic testing of carbon fiber reinforced plastics demonstrates his forward-looking approach to data-driven NDE. Vithanage’s work is foundational for the smart factories of Industry 4.0, where autonomous robots not only build but also inspect and certify components in real time.
