Alternate Current Field Measurement (ACFM)

ACFM Is In Use Worldwide In Almost Every Industrial Sector. It Is Particularly Well Used For In-Service Inspection As An Alternative To MT / PT. ACFM Is Ideal For Crack Detection At Welds, Through Coatings And Has The Added Advantage Of Producing Crack Depth Information. Therefore, ACFM Can Provide Cost Benefits Over Conventional Surface Testing Methods Such As MT/PT Where The Removal Of Coatings And Re-Application Is Costly. Typical Structures That Are Inspected With ACFM Include Cranes, Bridges, Theme Park Rides And Lamp-Posts. Ships Offer Many Opportunities For ACFM Inspection. The Ability Of ACFM To Inspect Through Paint And Even Underwater Enables Ship Hulls To Be Inspected Without Having To Enter Dry-Dock.
