Which weld configurations are commonly used to qualify welding procedures under CSA W47.1?

• A. Groove welds and fillet welds
• B. Only butt welds
• C. Only fillet welds
• D. Only square groove welds

Answer: (A)

The test for qualifying welding procedures under CSA W47.1 is meant to prove that the welding procedure can produce acceptable welds in the kinds of joints you’ll actually encounter in practice. The most representative and widely used configurations are groove welds on butt joints and fillet welds. Using both types in qualification coupons shows the procedure can handle different joint geometries, deposition patterns, and heat-affected zones, which is essential for confidence in real-world welding.

Testing only one type—whether butt joints, fillet joints, or a single square groove variant—would not fully prove the procedure’s versatility across common applications. That’s why groove welds and fillet welds are the standard combination for procedure qualification.
