Why should you remove metal items before welding?

• A. To prevent electrical shocks and burns
• B. To improve weld appearance
• C. To speed up the work
• D. To avoid leaving marks on clothing

Answer: (A)

Welding involves an electrical arc, so anything metal you’re carrying or wearing can conduct current from the circuit. If a ring, bracelet, watch, or metal fastener remains on you or in contact with the work, it can provide an unintended path for the current. That can lead to an electrical shock or a burn where the metal touches skin. Jewelry can heat up quickly in the arc and even fuse to the weld or surrounding metal, causing injury or contamination. By removing metal items, you eliminate the extra conductive paths and reduce the risk of shock, burns, or unwanted fusion to the work.
