PQR/WPS Preparation

Procedure Qualification Record (PQR) and Welding Procedure Specification (WPS) preparation are critical steps in welding quality management. They ensure welding processes, materials, and techniques meet required standards.

PQR: A PQR documents the welding variables, materials, and testing results required to produce an acceptable weld according to code standards. It forms the basis for creating a WPS.

WPS: The Welding Procedure Specification is a formal document that describes how a weld is to be performed to meet project requirements. It provides instructions to the welder.

Preparation Process Includes:

  • Selecting base materials and filler metals
  • Determining joint design, positions, and preheat/interpass temperatures
  • Setting welding parameters like current, voltage, and travel speed
  • Performing test welds and documenting results
  • Conducting mechanical and non-destructive testing to validate the procedure
  • Finalizing the WPS for use in production welding

Our team ensures that all PQRs and WPSs comply with standards such as ASME Section IX, AWS D1.1/D1.5, and ISO 15614.
