In the B-pressure test, how are bends distributed?

• A. 4 root and 4 face
• B. 2 root and 6 face
• C. 6 root and 2 face
• D. 8 root

Answer: (A)

Bend testing evaluates how a weld behaves when forced to bend, checking both the root of the weld and the weld face for cracks or weaknesses that can appear under deformation. In the B-pressure test, the setup uses eight bend sections around the weld, with four bends testing the root side and four testing the face side. This equal distribution ensures the test assesses the weld’s integrity from both perspectives, catching defects that may show up only on one side. If bends were all on one side, you’d miss issues on the opposite side, and uneven counts wouldn’t meet the required coverage. So the test uses four root bends and four face bends.
