Qw-483 Procedure Qualification Record (PQR) : SECTION IX, ASME Boiler and Pressure Vessel Code

This document is a Procedure Qualification Record (PQR) that summarizes the welding procedure used to qualify a welding process. It includes: 1) Details of the base and filler metals, including specifications, grades, and thicknesses. 2) Welding parameters like position, preheat and post-weld heat treatment temperatures, filler metal classification and diameter, and gas composition. 3) Electrical characteristics of the welding process including current, voltage, travel speed. 4) Results of mechanical tests on the weld including tensile tests, bend tests, and impact tests to qualify the welding procedure according to ASME Section IX standards.
