Program Overview

ACFM is an electromagnetic nondestructive testing technique that provides one pass inspection and capable of detecting and sizing surface or near surface breaking cracks in metals. The technique is suited for inspecting painted welded structures without removing the paint.

A modern ACFM inspection system comprises a field inducing probe with state of art low noise analogue electronics coupled with a built-in control system and easy to use Microsoft Windows based analysis software. The use of mathematical models to predict crack size. The models predict how electromagnetic fields are affected by the presence of breaking fatigue crack.

Advantage of ACFM technique in comparing to Magnetic Particle and Eddy Current NDT inspection techniques.

  • The ability to detect defects through 2.5-5mm (0.1”-0.2”) thick or more of non-conductive coating.
  • The ability to obtain depth information on cracks up to 1 inch (25mm) deep.
  • Easy testing at material boundary
  • No requirement for onsite calibration.
  • Detection and sizing in one instrument

Sadek’s accomplishments include receiving the ASNT Fellow Award in 1991, the Philip Johnson Honorary Member Award in 2009, the Robert D. MacMaster Gold Medal Award in 2013, the George Pherigo Tutorial Citation Award in 2016, Charles Sherlock Meritorious Service Award in 2020, and last Mentoring Award in 2024. He is currently the chair of the ASNT Awards and Honors Council and has served on the ASNT Business and Finance Committee from 2009 to 2024. Sadek has also held the position of chair of the CMC Electromagnetics Committee and was the Regional Director for Region 5.

Mr. Sadek is a pioneer and subject matter expert in the Electromagnetic ACFM Technique, with more than 15 years of experience in providing ACFM inspection and training. He has authored for ASNT books in this technology and other electromagnetic techniques such as Eddy Current and Remote field testing.
