                       WELD IMPERFECTIONS AND CODES IN RADIOGRAPHY

    Weld Discontinuities are designated by standard abbreviations.In radiography the weld imperfection either surface or internal type, 

A)     Surface Imperfections

B)     Internal Imperfections.

Standard abbreviations for weld discontinuities as listed below,
