Partial UT-S scan
Partial UT-S scan
(OP)
I recently was asked to perform UT-S on a thick member prior to its completion to judge if the root pass is acceptable. Has anyone performed scans on a partially welded joint? can it be done effectively?





RE: Partial UT-S scan
Like all UT 'problem joints', PLOT IT OUT, preferrably at twice or even 5x actual scale. This will show you how much coverage you can get. And the plot will show where you will start getting anomolies due to the unwelded portion.
