ACFM

Eddyfi® TSC Amigo2 and PACE Units

Alternating current field measurement (ACFM) is an electromagnetic technique used for the detection and sizing of surface breaking cracks in metallic components and welds. It combines the advantages of the alternating current potential drop (ACPD) technique and Eddy Current Testing (ECT) in terms of defect sizing without calibration and ability to work without electrical contact respectively.

Benefits

  • Applicable for base material or welds, ferritic or non-ferritic conductive metals
  • Can be used on hot surfaces, underwater, or in irradiated environments
  • Provides both depth and length information
  • Accurate sizing of defects up to 25mm in depth
  • Requires minimal surface preparation and can be applied over paint and other coatings
  • Applicable for under water inspection as well as normal inspection
  • Inspection data can be stored and analysed offline
  • Inspection can be encoded
  • Provides a permanent record of indications
  • Ongoing monitoring capability
  • High temperature capability
