Abstract

Electromagnetic acoustic testing (EMAT) and pulsed eddy current testing (PECT) are two representative electromagnetic nondestructive testing techniques that exhibit significant complementarity in defect sensitivity depth, detection mechanisms, and engineering adaptability. In recent years, driven by the increasing safety assessment requirements of pressure pipelines and pressure vessels, EMAT-PECT hybrid nondestructive testing has attracted growing research attention. This paper presents a systematic review of recent advances in EMAT-PECT hybrid nondestructive testing technology. Emphasis is placed on the composite detection mechanism, evolution of technical approaches, system integration strategies, data fusion methodologies, and current engineering applications. Future research directions are also discussed. This paper can provide a reference for research and engineering implementation of nondestructive testing technologies for complex structures such as pressure pipelines and pressure vessels.
