Alternating Current Field Measurement (ACFM) stands as a revolutionary electromagnetic technique utilized by TechCorr for identifying and sizing surface-breaking cracks in welds and metallic components.

Unlike traditional methods, ACFM does not necessitate direct contact with the material's surface, offering unparalleled versatility and efficiency. By emitting an electric current into the component, the ACFM probe detects disturbances in the electromagnetic fields close to the surface, pinpointing defects with remarkable precision.

TechCorr's expertise extends to employing ACFM on a diverse range of surfaces, including those with strictly-adhered coatings and minor scaling and debris, eliminating the need for pre-cleaning. This technique allows for rapid inspection and accurate defect analysis, even at elevated temperatures up to 900°F. TechCorr's utilization of ACFM extends across various industries, from offshore platforms to oil and gas facilities, providing clients with unparalleled inspection capabilities and ensuring the integrity and reliability of critical infrastructure components.
