Re: [MW:17933] Linear indications on H beam

 Dear all,
Do one sample for mechanical and chemical test. if it is meeting the requirement of material standard ,then you can use it.
check one sample after blasting the line mark is visible or not.

Hi,

We did UT and there is no lamination defect. the indication can be found only on the surface of the H Beam and is about 2mm deep on the whole surface.

Dear Joe, 
           In my suggestion, 1st u will do UT in that specify area, whether if it is a lamination found is rejected , due to some material problem will come sometimes. (or) the lamination is not found means it is easily repairable.....

Thanks..
