The need for pretested welding procedures that are supported by adequate testdata and that satisfy the technical requirements for the commonly used construction codes and specifications has beenexpressed by many individuals and organizations. The purpose of a welding procedure qualificat
33、ion is to provide test datafor assessing the properties of a weld joint.This Welding Procedure Specification is an outgrowth of the coordinated work of the Welding Procedures Committee ofthe Welding Research Council and the AWS B2 Committee on Welding Procedure and Performance Qualification. TheWeld
