Which code do bend test requirements for weld procedures come from?

• A. ASME Section IX
• B. AWS D1.1
• C. ASTM A370
• D. API RP 2X

Answer: (A)

Bend testing is used to check that a welding procedure can produce a ductile, crack-free weld when the joint is bent, simulating service stresses. ASME Section IX is the code that specifies how to qualify a welding procedure, including the bend test and the acceptance criteria for the test results. When you qualify a WPS, you weld a coupon with the procedure, bend it to the required angle, and inspect for cracks or defects in the weld metal and heat-affected zone; passing confirms the procedure is qualified for that service. Other codes you might encounter address different scopes or applications, but the formal bend test requirements for welding procedure qualification come from ASME Section IX.
