In industries where welding is a core part of the fabrication process—such as oil & gas, shipbuilding, construction, power, and heavy engineering—adherence to welding standards is not optional; it’s essential. The foundation of any high-quality, code-compliant welding operation lies in a well-documented Welding Procedure Specification (WPS) and a validated Procedure Qualification Record (PQR). Across India, Apeiwtes AWS Technology Center has emerged as a trusted partner in delivering expert WPS and PQR services that meet both national and international codes.
What Are WPS and PQR?
Welding Procedure Specification (WPS) is a formal written document that outlines the welding process to be followed for a specific job. It includes parameters like:
- Welding process (GTAW, SMAW, FCAW, etc.)
- Base metal and filler metal specifications
- Preheat and post-weld heat treatment
- Joint design and position
- Electrical characteristics (voltage, amperage, travel speed)
