The Application of Dual-frequency Eddy Current Testing Technology in the Production of Zirconium Tube

Through theoretical analysis in combination with the practical situation of the production, testing parameters for the dual-frequency eddy current test were determined. This paper introduces the dual-frequency eddy current testing technology applied in the production of zirconium alloy tube for nuclear application, and further verifies the practicability and importance of quality inspection by dual-frequency eddy current testing technology in zirconium alloy tubes for nuclear application.
