Apart from radiograhpy ...how do we decide Ultrasonic test , Magnetic particle test, Dye pentrante tests or any other if applicable, for welds (Fillet or Grooved or both) in category D, Skirts, base rings, skirt to head, lifting lugs, saddles, etc
Is there any mandatory requirements in ASME to follow. if not what are the suggested practices...?
