Weld Procedure Qualification Reports & Logs

Welding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test.

They can also provide the instructions for the welder to use in production in order to produce acceptable welds. Usually welding procedures are developed in accordance with a welding code or standard, and with few exceptions*, require that physical weld samples be produced, inspected, and tested to establish qualification. Welding procedures are usually divided into two categories, the Procedure Qualification Record (PQR) and the Welding Procedure Specification (WPS).

Reports on the procedures, welders, and materials are key to mitigating risks and helping to ensure repeatability in welded components and systems.

A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements.
