About this publication

This standard provides a reference guide for the kinds of nondestructive examination methods that are used to verify that welds meet the requirements of a code or specification. The nondestructive examination methods described are: (1) Visual (VT) (2) Liquid Penetrant (PT) (3) Magnetic Particle (MT) (4) Radiographic (RT) (5) Ultrasonic (UT) (6) Electromagnetic (Eddy Current) (ET) (7) Leak (LT) The types of discontinuities detected with each method and their causes are discussed. Acceptance criteria are not addressed in this standard. Requirements for nondestructive examination and acceptance criteria should be specified in procurement documents prior to the award of contracts. Principal factors to consider when choosing an examination method are the advantages and limitations of the method, anticipated type and size of discontinuity, acceptance standards, and cost. Annex A is a guide to process selection.
