Research on the Application of Marine Eddy Current Testing Technology in Non-destructive Inspection of Ship Structures
Non-destructive inspection is a necessary method to ensure the quality of hull structures and an important basis for verifying whether welding seams meet specifications.There are many types of non-destructive inspection techniques,each with its advantages and disadvantages.Eddy current detection technology is a non-destructive inspection method suitable for metal parts on structural surfaces or near-surface areas.The basic content of eddy current detection technology is based on the principle of electromagnetic induction,which detects and analyzes changes in the magnetic field and determines the shape and variation of eddy currents,thereby determining the type and characteristics of defects.This detection method can sensitively perceive the physical properties of ferromagnetic or non-ferromagnetic materials,and can also detect defects contained in the structure and scale,which has been used in non-destructive inspection of ship structures.
