Eddy current testing is used to detect surface and near-surface flaws in conductive materials.
This non-destructive testing technique is non-hazardous and commonly used in industries such as aerospace, rail, automotive, marine and manufacturing. One of the major advantages of eddy current testing is that inspection requires minimum preparation as there is no need to remove surface paint or coating. This makes it suitable for inspecting painted structures, parts and components.
Eddy current testing equipment is highly portable, reliable and can detect very small cracks. Results are instant, ideal for on-site testing on-site and plant inspections. Flaws can be reported immediately to site and operation managers, allowing for quicker decision making. In addition, the portability of equipment means that we can inspect equipment or assets that are difficult to access, and test complex shapes and sizes.
Eddy current testing uses electromagnetic induction to detect defects in both ferrous and non-ferrous materials by inducing an eddy current field in the specimen under test. A variety of inspections can be performed with eddy current testing and it is typically used for surface and near-surface flaw detection, metal and coating thickness measurement, and metal sorting by grade and hardness.
Our inspectors are highly experienced in performing this non-destructive technique and are PCN or ASNT Levels 2 and 3 or NAS410/EN479 Levels 2 and 3 qualified in eddy current testing.
Intertek is committed to offering Total Quality Assurance and ensuring plant inspections meet deadlines and are carried out safely and efficiently. Maintenance schedules are co-ordinated to ensure minimum disruption to your business activities and planned with an optimum level of NDT personnel to achieve the requisite inspection within the shortest possible time.
Eddy current testing on tubes
Eddy current testing on tubes in heat exchangers, condensers, air conditioning and air coolers, requires specialist equipment and technical expertise. Intertek’s NDT inspectors can perform this specialist advanced method.
