Other industry requirements are not nearly so restrictive.
There are other situations where gross oxidation from lack of purge would be quite evident on a radiograph. This is causing problems on a project.

Regards, By BryonLewis Date I thought it was a typo, undercut not being on the VT list. I think it is a good idea to write in the "comments" section of rt film interpretation RT report that undercut has been detected, but can't be evaluated.

I see it as a little bit problematic that the RT technician actually sign that a given weld is acceptable according to a certain standard, when he can't evaluate several kinds of defects. Course Description This course is designed to assure practitioners and their employers rt film interpretation the principles of radiographic rt film interpretation are reliably applied to the examination of welds.
Incomplete penetration IP or lack of penetration LOP occurs when the weld metal fails to penetrate the joint. It is one of the most objectionable weld discontinuities. Lack of penetration allows a natural stress rt film interpretation from which a crack may propagate.
The appearance on a radiograph is a dark area with well-defined, straight edges that follows the land or root face down the middle of the weldment.
Radiograpic Film Interpretation
Incomplete fusion is a condition where the weld filler metal does not properly fuse with the base rt film interpretation. Internal concavity or suck back: Internal concavity or suck back is a condition where the weld metal has contracted as it cools and has been drawn up into the root of the weld.
On a radiograph it looks similar to a lack of penetration but the line has irregular edges and it is often quite wide in the middle of the weld image.
Internal or Root Undercut: Internal or root undercut is an erosion of the base metal next to the root of the weld.
RT Film Interpretation
In the radiographic image it appears as a dark irregular line offset from the middleline of the weldment. Undercutting is not as straight edged as LOP because it does not follow a ground edge. External or crown undercut: External or crown undercut is an erosion of the base metal next to the crown of the weld.
In the radiograph, it appears rt film interpretation a dark irregular line along the outside edge of the weld area.
Offset or mismatch are terms associated with a condition where two pieces being rt film interpretation together are not properly aligned.
The radiographic image shows a noticeable difference in density between the two pieces. The difference in density is caused by the difference in material thickness.
The dark, straight line is caused by the failure of the weld metal to fuse with the land area.
