| description | Eddy current testing based on the principles of electromagnetic induction. A
magnetic field is developed in and around the conductor when alternating current is
applied. Eddy current technique can be used on all materials which can conduct
electric to locate surface, subsurface cracks, measurements of the thickness on
metallic plates and also non-metallic coatings on test objects. The testing is done by
using weld probe on conductive material such as steel to detect any crack or defects
in the part of welded steel sample. From the testing, the position and width of the
crack can be identifying by analyse the peak of signal. The peak show that there is
contribution of small or large defect in the welded sample. Other than that, the value
of position and width will determine the place of the crack and how deep the crack
on the test object. Crack pattern is different due to the changing in frequency of
current running through the coil during the testing. When the frequency is increase,
the length of crack pattern will decrease. |
