Alternating Current Field Measurement (ACFM)
ACFM stands for Alternating Current Field Measurement. It is a non-destructive testing (NDT) technique that is primarily used for the inspection of ferrous materials, such as steel, to detect and size surface-breaking cracks and other defects. key features and aspects of Alternating Current Field Measurement (ACFM)
Detection and Measurement
ACFM has several advantages, including the ability to inspect surfaces with coatings, the provision of quantitative data on defect size, and the capacity to detect defects in various orientations.
• Quantitative Analysis.
One of the advantages of ACFM is its ability to provide quantitative data about the size of surface cracks. This quantitative analysis makes it a valuable tool for assessing the severity of defects and determining whether they meet acceptable standards.
• Surface Inspection.
ACFM is particularly useful for inspecting surfaces that may be coated or covered with paint, rust, or other materials. It can effectively detect and size defects even when they are not visible to the naked eye.
