Eddy current testing (ECT) is a method for the inspection of metallic parts. The probe, excited with an alternating current, induces an eddy current in the part being inspected. Any discontinuities or material property variations that change the eddy current flow in the part are detected by the probe as a potential defect.

The eddy current technique is now recognized to be fast, simple, and accurate. The technique is widely used in the aerospace, automotive, petrochemical, and power generation industries in the detection of surface or near surface defects in materials such as aluminum, stainless steel, copper, titanium, brass, In-conel, and even carbon steel (surface defect only). Very sensitive to cracks.



Applications’ of ECT

  • Detection of cracks in SS vessels and tanks
  • Detection of cracks in turbine blades
  • Inspection of aerospace structures
  • Detection of cracks in bolt holes
  • No consumables used – e.g. Ink & contrast paint.
  • Ability to test areas with poor access.
  • No surface preparation required – e.g. Paint doesn’t need to be re- 
moved, saving time in preparation for the inspection and in any re-coating of surfaces.
  • Improved sensitivity-ability to detect smaller defects using specially developed Weld Probes.

Advanced Inspection & Testing Company Limited (AIT) specializes in performing inspections of welds and forgings using automated / Semi-automated ultrasonic phased array method.

The Major use of Phased Array Ultrasonic Testing or PAUT Inspection is to evaluate the entire volume of a weld for the detection of potentially detrimental discontinuities in a weld in accordance with written procedures, guidelines, standards and codes. It covers the materials and components, design, fabrication, assembly, erection, examination, inspection and testing of piping.


Automated / Semi automated Ultrasonic inspection offers many benefits to our client base and is utilized on capital projects, maintenance inspection, turnaround scheduling/planning and shutdown/turnaround/ outage situations. From high speed erosion/corrosion scanning systems using computer controlled ultrasonic scanners and software, highly sensitive P-Scan systems for accurate identification, location and sizing of defects in weld material and “on-line” inspection of various assets for prioritization in turnaround schedules, phased array ultrasonic inspection is used for weld inspection in lieu of radiography and a variety of other applications, to high speed Time of flight Diffraction, AiT provides the appropriate Inspection solution to your site.

Some of the factors that we consider when recommending the appropriate Inspection technology are: the anticipated damage mechanism, operating condition of the asset, ability to access the area in question and the proximity of trade involvement to the inspection area.



either enhance existing ultrasonic capability, or as a complete replacement for radiography. Advanced Phased Array Ultrasonic inspection offers many benefits to our client base and is utilized on capital projects, maintenance inspection, turnaround scheduling/planning and shutdown/turnaround/ outage situations. From high speed erosion/corrosion scanning systems using computer controlled ultrasonic.



Benefits of AUT/SAUT PHASED ARRAY

  • PAUT Inspection gives more information about a defect’s characteristics
  • Phased Array Ultrasonic Testing is Ease of set-up
  • It is easy to interpret
  • Compatible software that can export measurements into spread sheets.
  • Rapid inspections with digital recording of data
  • Digitally-encoded scanning for accurate sizing
  • High probability of detection (POD) especially for cracks and lack of fusion.
  • Phased Array allows defect height measurement allowing volumetric consideration of flaw severity versus just type and length, leading to accurate sizing of defects height and less rejects/repairs using Engineers Critical Assessment.
  • No radiation, hazard, or additional licensing or personnel.
  • No screened off areas, work can go while conducting Phased Array Inspection.
