Comparison of WPS and Pqr for Pressure Vessel Welding

The need of the any fabrication industry is to evaluate the standard procedures of welding at the production flow and they want to check whether the processes are according to WPS (Welding Procedure Specification) or not.The book is about PQR (Procedure Qualification Record) according to ASME Sec. IX code.Readings of actual joints for different type of reactors (AE-Open type, CE-Closed type) with same joint and different size (i.e. 6300 Lit., 4000 Lit....) are taken. The record shows actual variable of processes.
