The Welder Performance Qualification Record (WPQR) form serves to document a welder's qualifications. It verifies that the welder has passed specific tests according to industry standards. This record is essential for ensuring that welders are skilled and capable of performing their tasks safely and effectively.
The WPQR form requires several key pieces of information, including:
-
Welder’s name and identification numbers
-
Test number and date
-
Welding Procedure Specification (WPS) reference number
-
Details about the welding process, including type and position
-
Mechanical test results and non-destructive examination results
-
Signatures from qualified personnel
This information helps verify the welder's capabilities and compliance with relevant standards.
The performance qualification is tested through practical welding tests that assess the welder's skills. These tests can include various welding processes, positions, and materials. The results are then documented on the WPQR form. Depending on the requirements, tests may also involve mechanical testing and non-destructive examination to ensure the quality of the welds.
What does "qualified position" mean?
The term "qualified position" refers to the specific welding positions in which a welder is certified to work. Positions are categorized by numbers and letters, such as 1G, 2G, F, H, V, and O. A welder must demonstrate proficiency in these positions during testing to be qualified for that specific type of work.
What happens if a welder fails the qualification test?
If a welder fails the qualification test, they cannot use the WPQR to certify their skills. The welder may need to undergo additional training or practice before retaking the test. It is important for welders to achieve a passing grade to ensure they meet industry standards and maintain safety in their work.
How long is the qualification valid?
The validity of the qualification can vary based on the specific standards and regulations in place. Generally, a performance qualification remains valid as long as the welder continues to perform welding tasks regularly. However, if a welder has not welded for an extended period, they may be required to retake the qualification test to ensure their skills are up to date.
