Manual UT for the volumetric Inspection of cast, forged and welded materials. UT may be limited by component geometry (size, contour, surface roughness, complexity and discontinuity orientation) in addition internal structure characteristics grain size/orientation and acoustic impedance must be favourable.
The Ultrasonic test falls into the following categories
Internal Discontinuity detection
Cross section evaluation(thickness Testing)
Bond characterisation and corrosion mapping
UT can be used to verify compliance to the manufacturing standard or for inservice inspections
