Inspection, Ultrasonic, Wrought Metals, Process for
|Publication Date:||1 April 2020|
The purpose of this standard is to provide uniform methods for the ultrasonic inspection of wrought metals and wrought metal products.
The methods for ultrasonic inspection in this standard are applicable in the detection of flaws in wrought metals and wrought metal products having a cross section thickness equal to 0.250 inch or greater. Round bar and billet may use AMS2628 techniques and equipment for billet over 4.5 inches using the acceptance criteria of Table 6 of AMS-STD-2154. Wrought metals include forging stock, forgings, rolled billet or plate, extruded or rolled bars, extruded or rolled shapes, and parts made from them. Application of the methods in this standard is not intended for non-metals, welds, castings, or sandwich structures.
