Re: [MW:11653] How can identify rolling direction in plate?

Hi limesh,
 
Take a sample from one edge of the plate & send it for testing for the direction of grain elongation. Generally the elongation is lesser towards the rolling end.
 
ARAMCO Spec's for HIC testing calls for samples to be taken from the end of the plate where the rolling ends. We generally send the samples to laboratory for the evaluation of the rolling direction.

Dear All,

For preparing test pieces for PQR, the following item to be fulfilled as per a document.

"For butt weld test assemblies Identification of the rolling direction of the used plates shall be provided."

My query is that,is it possible to identify the rolling direction by naked eye?If possible what is the trick behind it?



Regards,

Limesh
