About

Weican Guo is a pioneering researcher in the field of robotic non-destructive testing (NDT) and maintenance for industrial pressure infrastructure. His work centers on developing specialized robotic systems for the in-pipe inspection, repair, and maintenance of pressure pipelines and spherical tanks—critical assets in the oil, gas, and petrochemical industries. Guo’s major contributions include the design and implementation of a novel robot-based system for ultrasonic inspection of pressure pipelines, addressing the challenge of inspecting pipelines that are often overhead or buried. His research on ultrasonic inspection techniques for pipe elbows, which are prone to severe corrosion, has advanced the use of traditional and phased array ultrasound for inline inspection. More recently, Guo has developed a wall-climbing robot for Time-of-Flight Diffraction (TOFD) inspection of welding seams in spherical tanks, a critical safety application. He has also created a robotic system for inner wall derusting and grinding, solving a long-standing industrial bottleneck. With over 24 citations across his most-cited works, Guo’s research is directly impacting the safety and longevity of critical energy infrastructure.
