Atomic hydrogen welding is what shade?

• A. 8-12
• B. 10-14
• C. 12-16
• D. 14-18

Answer: (B)

Eye protection for welding is all about choosing a filter shade that matches the brightness of the arc. Atomic hydrogen welding produces a very bright arc with strong UV and infrared radiation, so a darker filter is needed to protect the eyes while still letting you see the weld pool well enough to work safely. The standard recommendation for this process is a shade range of about 10 to 14. Shades lighter than this, like 8 to 12, wouldn’t provide enough protection from the intense arc light. Shades darker than this, such as 12 to 16 or 14 to 18, would make it harder to see the weld clearly and could slow you down or hinder inspection, even though they offer more glare protection. So the 10 to 14 shade is the appropriate balance for atomic hydrogen welding.
