Which shade number appears in more than one welding category?

• A. 10
• B. 11
• C. 12
• D. 14

Answer: (C)

Eye protection in welding relies on shade numbers that filter the bright arc radiation. Different welding processes produce different levels of brightness, but some shade numbers cover the typical brightness seen in more than one process. Shade 12 sits in that overlap range, making it commonly recommended for several welding methods, such as both shielded metal arc welding and gas metal arc welding, and sometimes used for TIG as well. That overlap is why this shade appears in more than one category, so it’s the best choice for the question. Always verify the exact shade needed for your specific process, current, and material per the safety standard or job procedures.
