What is welding flash?

Welding flash refers specifically to burns caused by exposure to excessive ultraviolet (UV) or infrared (IR) rays generated during the welding process. When an individual is welding, the intense light produced can lead to injuries known as flash burns, which typically affect the eyes and skin. These burns can occur in unprotected areas, highlighting the importance of using proper protective gear, such as welding goggles and skin protection, when conducting welding activities.

The other choices do not accurately describe welding flash. A chemical reaction, a tool used for welding, or a type of metal alloy do not pertain to the concept of flash burns resulting from UV or IR exposure during welding operations. Understanding the nature of welding flash is crucial for safety in environments where welding takes place.
