Procedure Making & Interpretation of Data as per Procedure or Clients requirements.
PROCEDURE NEED FOR PAUT as below: (for perticular job requirements)
1.0 SCOPE
1.1 This procedure describes the method and techniques to carry out Phased Array Ultrasonic Testing (PAUT) on
fusion welded joints in metallic materials equal to and greater than 10mm thick which exhibit low ultrasonic
attenuation (especially that due to scatter).
1,.2 Either manual operation or encoded semi-automated scanning will be used.
1.3 Semi-automated scanning will require a holding fixture equipped. With a position encoder and provision to
hold the probe(s) in a fixed orientation to the weld. Probe motion for semi-automated scanning shall
incorporate a guide-bar to provide a fixed standoff.
1.4 This procedure shall be used with inspection techniques applicable to the specific geometries for wall
thickness, weld preparation and weld process. These are attached as Appendices of this Procedure.
1.5 This procedure describes Magic NDT's standard practices for carrying out PAUT. Unless other contractual
details are issued, this document shall take precedence.
