If flash is not seen on the full periphery of the stud, what action must be taken?

• A. Replaced or repaired by adding minimum fillet weld while still adhering to the code and extending 10mm (3/8") beyond each side of the discontinuity
• B. Ignore the issue
• C. Replace the stud entirely
• D. Weld a patch elsewhere

Answer: (A)

When a stud weld doesn’t show flash all the way around the full circumference, there’s a lack of complete fusion at the periphery. That kind of discontinuity can weaken the joint, so the repair must restore full circumferential weld coverage. The required approach is to add a minimum fillet weld around the stud, ensuring the weld extends 10 mm (3/8 inch) beyond each side of the discontinuity. This method reestablishes a continuous weld face and adequate throat while keeping the stud in place and complying with the code. Ignoring the issue would leave a defect, and replacing the stud or simply patching elsewhere would not reliably address the incomplete periphery or maintain the intended load path.
