About

Peng Junfei is a specialist in intelligent robotic welding systems, with a primary focus on seam tracking control for mobile welding robots. His research addresses critical challenges in automated welding for large-scale industrial applications, such as shipbuilding and spherical tank construction. Peng’s major contributions include the development of predictive fuzzy control algorithms to overcome the limitations of rotational arc sensors, which cannot detect upcoming seam positions in curved paths. His 2008 paper on this topic, with 10 citations, demonstrates a novel approach to improving weld quality and efficiency. Additionally, he proposed a coordinate control method for broken-line welding seams, employing a self-tuning fuzzy controller to synchronize cross-slider and wheel movements, achieving precise tracking. This work, cited 5 times, highlights his ability to integrate sensor feedback and adaptive control for complex geometries. Peng’s achievements lie in advancing the autonomy and accuracy of welding robots, reducing reliance on manual intervention. His research remains foundational for engineers developing intelligent manufacturing systems, particularly in heavy industries where weld integrity is paramount.
