The inspection of heat exchanger tubes is a crucial step to ensure the safety of heat exchang-ers.However,current single inspection method can only detect specific defects,and fail to achieve compre-hensive detection of corrosion defects across the entire cross-section of heat exchange tubes.Traditional di-agnostic methods rely heavily on manual judgment and cannot fully analyze and diagnose the signals and in-formation.This paper proposes a LightGBM-LR diagnostic model by comprehensively utilizing the electro-magnetic acoustic,optical methods,and integrating all the data obtained from these methods.Experimental results show that the detection method can effectively identify defects such as through-holes and annular grooves in heat exchange tubes.
