Ultrasonic evaluation of the bonding characteristics in an infinitely chilled double poured rolls is carried out. During manufacturing process there are defects in the form of small holes or inclusions in these rolls. These defects act as points of stress in addition to the service stresses. By grinding, stress redistribution occurs. The shell–core interface is vulnerable to such stresses. Ultrasonic testing can be used to establish the critical points of these stress and hence predict their failure.
