What is a Welder Performance Qualification (WPQ)?

• A. A test demonstrating that a welder can produce welds meeting specified acceptance criteria
• B. A test that checks knowledge of welding theory
• C. A test of material hardness
• D. A test that measures the speed of welding

Answer: (A)

A Welder Performance Qualification shows that a welder can consistently produce welds that meet the required acceptance criteria for a given welding process, material, joint type, thickness, and position. It involves the welder creating test welds, which are then inspected and tested (such as visual checks and specified nondestructive or mechanical tests) to verify they pass the stated criteria. This is about actual welding performance under defined conditions, not about knowledge of welding theory, measuring material hardness, or testing welding speed. The qualification proves the welder’s ability to perform welds that meet the project or code requirements in production.
