This book has been prepared to give inspecting engineers, welding engineers, designers, producers and purchasers of welded plant, an up-to-date under-standing of non-destructive testing (NDT) methods and their scope of application to welds and welded structures.

Non-destructive testing is a technology which is continually advancing and 

it is necessary, at intervals, to update any published information on the 

subject. Even the well established techniques such as magnetic crack detec-

tion or radiography show considerable advances when considered over, 

say, ten-year intervals, and in the same period completely new techniques 

can pass from the research laboratory phase into commercial industrial 

use.

Because fabrication techniques such as welding require considerable skill, it 

is inevitable that mistakes will occur, that flaws will be incorporated into the 

material, and that therefore some post-fabrication testing will be essential to 

discover any such serious flaws which may impair performance. Today, also, 

there is a new emphasis on in-service inspection of fabricated structures and 

on structure monitoring. Non-destructive testing is an inspection process 

which forms part of the whole quality assurance/quality control (QA/QC) 

scheme.
