Destructive testing, nick breaks.
Destructive testing, nick breaks.
(OP)
When examining nick breaks after the specimen is broken, I have encountered shiney spots in the weld metal. It isn't slag, non fusion, porosity, or fish eyes. I've been told by a welding engeneer that it was brittle fracture but would like other opinions. Several welding inspectors I have worked around will fail the weld test for these shiney spots. Someone please advise as to exactly what these shiney spots are, and should the weld test be disqualified? Olefazz

This is not a desireable condition, but I would not reject a nick break for this alone, but insure that the welder is following the WPS for production welding.
