The Sunburn Risk in Arc Welding

When you’re standing in front of an arc welding operation, you’re not just dealing with intense heat and bright light; you’re also exposed to a significant amount of ultraviolet (UV) radiation.

This invisible but powerful form of radiation is produced as a natural byproduct of the welding process.

The intense electric arc generates temperatures that can reach several thousand degrees Fahrenheit, causing the metals to melt and emit UV rays as they vaporize.

UV radiation is classified into three types: UVA, UVB, and UVC. UVA and UVB radiation, which are particularly relevant in welding, can have harmful effects on the skin. While UVA rays penetrate the skin more deeply and can lead to premature aging, UVB rays primarily affect the skin’s surface, potentially causing sunburn.

Can Arc Welding Cause Sunburn?

In response to the central question, the answer is a straightforward “yes.”

Just as spending time under the scorching sun without protection can result in sunburn, the intense UV radiation produced during arc welding poses a similar risk to exposed skin.

The consequences of welding-induced sunburn can range from temporary discomfort to more severe skin damage, depending on various factors.

Factors that Increase Sunburn Risk

Several factors can increase the risk of sunburn while arc welding:

  1. Welding Intensity: The intensity of the welding arc, which can vary depending on factors like current settings and welding process, directly impacts the amount of UV radiation emitted. Higher-intensity welding generates more UV radiation, increasing the risk of sunburn.
  2. Exposure Time: The longer you spend welding without proper protection, the greater the risk of sunburn. Extended exposure to UV radiation compounds the damage to your skin.
  3. Skin Sensitivity: Individual skin types and sensitivities vary. Some people may be more prone to sunburn than others. People with fair skin are generally at a higher risk.
  4. Angle and Position: The angle at which you work and your proximity to the welding arc also play a role. Welding at certain angles or being too close to the arc can result in increased UV exposure to specific areas of your body.
