Pearlite Banding Problem
Pearlite Banding Problem
(OP)
Hi All,
We have found pearlite banding layer running across the parent plate below the weld. These plates are being used to manufacture caisson shoes. We understand that if, Manganese is too much it can segregated to weld and cause brittleness.
Does anyone knows an inspection method which filter out abnormal amounts of pearlite banding or abnormal volumes of inclusions which can have effect on material integrity? UT does not distinguish between the two.
Thanks in advance

I don't think so. do you know any other inspection techniques?

However this pearlite banding thing occurs 0.5 - 0.75 in.below the surface of the base plate.
Thanks
