Ultrasonic Inspection of a 1.7 m (68 in.) Diam 8822 Steel Billet and the Ring Into Which It Was Rolled
The large steel ring produced for a nuclear application from a billet of 8822 steel was inspected. The large billet was first forged into a doughnut preform in a large press, and then formed into the ring by ring rolling. A straight-beam ultrasonic inspection was instituted and calibrated using the back-surface-reflection method to determine whether adequate ultrasonic penetration was available. Areas of indications were noted at approximately midheight and adjacent to the bore area. An axial angle-beam inspection from the outside was performed, mainly in the area of indications to reveal detectable indications. The indications were not considered serious...
