What is the purpose of welding procedure qualification tests?

The purpose of welding procedure qualification tests is primarily to verify the correctness of welding methods. These tests are designed to confirm that the welding procedures being used produce welds that meet specified standards for quality, strength, and performance. This ensures that the methods employed are suitable for the materials and conditions involved in the welding process.

During these qualification tests, various parameters such as welding technique, filler material, and heat input are assessed to ensure they align with industry standards. The results help guarantee that welds will perform reliably under specified service conditions, which is critical for the safety and integrity of welded structures.

While evaluating the durability of welding materials and certifying welders may be important aspects in the welding industry, the primary focus of welding procedure qualification tests is to establish that the methods used to create the welds are appropriate and effective for achieving the desired outcomes in terms of quality and safety.
