SAMPLE FORM for WELDING PROCEDURE QUALIFICATION RECORD PQR

Understanding the welding procedure qualification record (PQR)

The welding procedure qualification record (PQR) is a crucial document that outlines the specific parameters and results of a welding procedure. It serves as a formal record that demonstrates the welder's ability to produce sound welds under defined conditions. The PQR includes essential information such as the materials used, the welding process, and the mechanical properties of the weld. This document is vital for ensuring compliance with industry standards and regulations, making it an indispensable part of the welding certification process.

Key elements of the welding procedure qualification record (PQR)

A well-structured PQR contains several key elements that provide comprehensive details about the welding process. These elements typically include:

• Base materials: The types and specifications of the materials being welded.
• Welding process: The specific welding method used, such as MIG, TIG, or stick welding.
• Welding parameters: Details such as amperage, voltage, travel speed, and heat input.
• Test results: Mechanical properties of the weld, including tensile strength, impact resistance, and hardness.
• Welder qualifications: Information about the welder's certification and experience.

Including these elements in the PQR ensures that it meets industry standards and can be used effectively for quality assurance and compliance purposes.

Steps to complete the welding procedure qualification record (PQR)

Completing a PQR involves several systematic steps to ensure accuracy and compliance. Here’s a general outline of the process:

1. Gather materials: Collect all necessary base materials and welding equipment.
2. Define welding parameters: Establish the welding parameters, including voltage, amperage, and travel speed.
3. Perform welding: Execute the welding process according to the defined parameters.
4. Conduct testing: Perform mechanical tests on the welded joints to assess their properties.
5. Document results: Record all findings, including test results and observations, in the PQR.

Following these steps helps ensure that the PQR is comprehensive and meets the necessary standards for welding qualifications.

Legal use of the welding procedure qualification record (PQR)

The PQR holds significant legal weight in the welding industry. It serves as evidence that a welding procedure has been tested and meets the required standards. In the event of a dispute or inspection, having a properly documented PQR can protect both the welder and the organization by demonstrating compliance with industry regulations. Additionally, it ensures that the welding practices adhere to safety and quality standards, which is essential for maintaining the integrity of welding projects.

How to use the welding procedure qualification record (PQR)

Using the PQR effectively involves understanding its role in the welding process. It should be referenced throughout the project to ensure that all welding activities align with the documented parameters. The PQR can be used for:

• Training: Educating new welders about the specific procedures and standards required.
• Quality control: Monitoring welding activities to ensure compliance with the documented procedures.
• Regulatory compliance: Providing necessary documentation during inspections or audits.

By utilizing the PQR in these ways, organizations can enhance their welding operations and maintain high standards of quality and safety.
