    Abstract - (Show below) - (Hide below)

    Covers methods for the radiographic examination of fusion welded circumferential butt joints in steel pipes primarily with wall thicknesses in the range 2mm up to and including 50mm by examination using the film inside and source of radiation outside or using film outside and source of radiation inside or using film and source of radiation both outside, finally using film and source of radiation both outside. Includes marking, density, explanatory information on the techniques, guide to choice of technique, alternative procedure for placement of IQI, example of record form for radiographic examination and flaw sensitivity in radiography : principles and background.
