WELDING ENGINEERING AND INSPECTION SERVICES
SERVICES
Welding Procedure Specification (WPS)
A Welding Procedure Specification (WPS) is a formal document that outlines the welding process, parameters, and techniques required to produce a sound weld. It includes details like materials, welding methods, joint design, preheat and post-weld treatments, and filler metals, ensuring consistency, quality, and compliance with industry codes and standards.
Procedure Qualification Record (PQR)
A Procedure Qualification Record (PQR) documents the results of welding tests used to verify a Welding Procedure Specification (WPS). It includes actual welding variables, test results, and inspection data. The PQR proves that the proposed welding procedure produces sound welds meeting required codes, ensuring safety, reliability, and structural integrity.
Welder Qualification Certificate (WQC)
A Welder Qualification Certificate (WQC) is an official document confirming a welder's ability to perform specific welding procedures to required standards. It verifies that the welder has passed practical tests under controlled conditions, ensuring competence, safety, and compliance with industry codes for producing high-quality, structurally sound welds in the field.
