WebUltrasonic testing (UT) comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material. These high frequency sound waves are transmitted into materials to characterise the material or for flaw detecting. Most UT inspection applications use short pulse waves with frequencies ranging from 0. ... WebTypical discontinuities found in the ingot are inclusions, blow holes, pipe and segregations. Nonmetallic inclusions such as Slag, Oxides and. Sulphides are present in the original ingot. Blow holes & Porosity are formed by gas which. is insoluble in the molten metal and is trapped. when the metal solidifies.
