About
Anthony Gachagan is a leading researcher in non-destructive evaluation (NDE) and ultrasonic testing, with particular expertise in automated inspection systems, phased array ultrasonics, and their integration with advanced manufacturing processes. His work sits at the intersection of Industry 4.0 technologies and quality assurance, focusing on enabling real-time, in-process defect detection in complex manufacturing environments such as multi-pass welding and Wire + Arc Additive Manufacturing (WAAM). Gachagan's most influential contributions include developing ultrasonic phased array inspection methodologies for WAAM components with embedded defects (78 citations), and pioneering roller probe systems and robotic platforms capable of performing NDE during — rather than after — the welding process. This in-process approach addresses critical industrial challenges including costly rework, reduced throughput, and delayed defect discovery. His sensor-enabled multi-robot inspection framework (46 citations) exemplifies his drive to merge intelligent robotics with rigorous NDE capability. Beyond ultrasonics, his research extends to eddy current array inspection for nuclear assets and novel applications of guided waves in robotic mapping. With over 380 cumulative citations across his top works, Gachagan's research is shaping the future of smart manufacturing quality control, making automated, reliable, and timely structural integrity assessment increasingly achievable across high-stakes industries.
