Eddy current is an electromagnetic technique, it’s completely non-destructive. It works on the principles of Electro Magnetic induction. There is no dangerous or hazardous chemicals involved with this technique.
AIRIS testing methods for ferrous and nonferrous materials including Pipes & plates for structural integrity & heat exchangers for commercial air conditioners. Our specialties are varied from construction to Industry.
Our specially trained technicians insert an inspection probe down the full length of each tube being inspected and observing the eddy current response on the test instrument screen. Coils located in the inspection probe produce an electromagnetic field which are effected by changes in the tube wall such as wall loss and pitting.
Eddy Current is limited to testing metallic materials and works best on non-magnetic alloys. It can be applied to magnetic materials, such as Monel, Nickel, Fermium or other Ferritic Stainless steels using magnetic saturation techniques.
