What test is performed on studs that have been repaired?

• A. They are ultrasonically tested
• B. They are bent at an angle of 15 deg
• C. They are visually inspected
• D. They are hammered to check for defects

Answer: (B)

After a stud repair, a bend test to a small angle is used to check the weld’s integrity. Bending the repaired area introduces tensile and shear stresses that reveal cracks, incomplete fusion, or other defects that might not be visible on the surface. A 15-degree bend is a practical, targeted test that can show whether the repair can withstand service-like bending without breaking. Visual inspection alone may miss subsurface flaws, and ultrasonic testing or hammer testing aren’t as routinely applied for this specific check; they’re either more involved or less reliable for catching common repair defects.
