WE are welding 36" X70 material .875 wall. We are quenching it directly
after welding, so we can have it cooled down for Automated Ultrasonic
testing. The only problem we are having is that when we do this, it
sometimes leaves some sort of heat marks on the cap that criss-crosses
diagnially across the weld. These marks will not hold dye when we PT
them, and we can take a wire wheel and they buff right off. My question
is, is this detremental to the weld and what would you technically call
this type of thing.
Thanks,
