Runoff tabs are used to produce which weld quality?

• A. A sound weld
• B. A faster weld
• C. A lighter weld
• D. A weaker weld

Answer: (A)

Runoff tabs are used to ensure a sound weld by giving the weld a controlled stopping point. The tab is welded to the joint as you progress, and you melt into the tab at the end, then stop. This prevents the end of the weld from forming a crater, which can crack or trap porosity and create weak fusion at the termination. By finishing into the runoff tab, you get a well- fused, defect-free end, and once the tab is removed, the actual weld remains solid and clean. So runoff tabs benefit the overall soundness of the weld, not its speed, weight, or inherent strength.
