There are only three things that will cause white indications, tungsten in the weld, contaminated flux or excessive filler material.

Subject: [MW:1813] RT of Duplex Stainless Steel
Dear All,
I am facing problem during NDT (RT) of Duplex St.Steel) . The RT film shows 4-5" long white indication in the weld area. We tried changing the screen but still the same things appear on the film.
The welds are welded with SAW process. Generally the porosities are expected if we use SAW welding for Duplex but this indications are strange for me. Does anybody have experienced the same ?
