Welcome to [NDT Inspection Portal]’s magnetic flux leakage (MFL) group, a place for professionals to connect and discuss the latest techniques and technologies in magnetic flux leakage inspection.
The non-destructive testing technique known as magnetic flux leakage (MFL) is used for the inspection of storage tank floors (mild steel plate). … When there is a velocity difference between the plate and the excitation system, eddy currents are induced opposing the applied magnetic field distorting its profile.
At the same point where there is an indication I make scans in different directions and the loss percentage values change. Being that theoretically it should not have change since I am performing the scan in the same indication.
