ECT is a non-destructive testing method that uses electromagnetic induction to detect surface and near-surface flaws in conductive materials. It is commonly used in industries such as aerospace, automotive, and manufacturing to inspect metal components for cracks, corrosion, and other forms of damage.
ECT works by inducing an alternating current in a coil of wire, which creates a magnetic field around the coil. When the coil is brought near a conductive material, eddy currents are induced in the material. These eddy currents create their own magnetic field, which interacts with the coil’s magnetic field. This interaction produces a signal that is detected by the coil, providing information on the material’s conductivity, thickness, and any flaws or defects present.
One of the main advantages of ECT is its ability to detect surface and near-surface flaws without requiring physical contact with the material being tested. This makes it a non-invasive testing method that is ideal for inspecting delicate or hard-to-reach components.

2.4 MFL (magnetic floor leakage Test)
MFL is a non-destructive testing method that is commonly used to inspect pipelines and other structures for corrosion and other forms of damage.
MFL works by using a magnet to magnetize the steel or iron material being tested. A magnetic field is then induced into the material, causing the magnetic field lines to flow smoothly through the material. When the material is not uniform, such as when there is a defect or corrosion, the magnetic field lines will be disrupted and create a leakage field. A sensor is then used to detect these areas of leakage, which can indicate the location and extent of damage.
One of the main advantages of MFL is its ability to detect corrosion and other types of damage to the structure being tested, even when it is located beneath coatings and other materials. This makes it a valuable tool for inspecting pipelines and other structures that are difficult to access or inspect using other methods.
