What should be done if a stud was removed due to tensile stresses?

• A. Replace the stud with a new one and re-torque.
• B. Area shall be ground smooth and flush. In areas where base metal has been removed, arc welding in accordance with the requirements of this standard shall be used.
• C. Apply a patch plate without welding.
• D. Leave as is.

Answer: (B)

When a stud carrying tensile loads has been removed, the repair must restore both the surface finish and the material around the fastening area so the joint can carry load without creating stress risers. Grinding the area smooth and flush eliminates sharp edges and abrupt transitions that can concentrate stress. If any base metal around the hole has been removed, arc welding in accordance with the standard is needed to restore the cross-section and reestablish the load path for the joint. This combination ensures the repaired connection has proper geometry, adequate strength, and compliance with the specified requirements.

Replacing the stud and re-torquing wouldn’t fix potential damage to the surrounding metal or restore the original load path. A patch plate without welding doesn’t recreate the necessary metal around the hole or the bonding of the joint. Leaving it as is would leave a weak, hazardous condition under tensile loading.
