Table 4 lists the various weld joint types and common NDE methods available<br />
to inspect their configuration. Table 5 further lists the detection capabilities of<br />
the most common NDE methods. Additional methods, like alternating current<br />
field measurement (ACFM), have applications in weld inspection and are<br />
described in this section but are less commonly used. The inspector should<br />
be aware of discontinuities common to specific base metals and weld<br />
processes to assure these discontinuities are detectable. Table 6 is a<br />
summary of these discontinuities, potential NDE methods and possible<br />
solutions to the weld process.
