Now, I have facing one of issue, At present  working with  Indian railway project, thirt party is also there from client side. They does't know what the wps & pqr becoz. Wps & PQR  is not mentioned in their spec./manual. But as per IS standard testing they have carried.
But 2nd authority is saying make wps & pqr.
Now question is...  whats the parameter to be set for rail section? Because all parameter are different from piping or structure. Whats format as per section IX or ...?

Requesting all of you, Please advice and send a sample wps & pqr  as per this mat. Spec.

Hello, you should review this standard D15.2/D15.2M:2013 RECOMMENDED PRACTICES FOR THE WELDING OF RAILS AND RELATED RAIL COMPONENTS FOR USE BY RAIL VEHICLES, it deals with thermit and flash welding processes.
