Quality Assurance
▪ Welding procedure Specification (WPS)
▪ Generated from the PQR and used as the guiding instructions for a
specific weld
▪ Provides tolerances (+/-) on essential variables
▪ Welder Qualification Record (WQR)
▪ Test to verify that welder/operator is competent and capable of
achieving the required results, consistently
▪ Assessed on a 6 monthly basis for continuity of skill
▪ PWPS, PQR, WPS & WQR form an important part of
a fabricators
quality management system and demonstrate commitment to
product quality and integrity
