What is a potential hazard associated with submerged arc welding?

Submerged arc welding (SAW) is characterized by its unique process in which an electric arc forms beneath a blanket of granular flux, shielding the molten weld pool from contamination. One of the potential hazards specifically associated with this method is the exposure to ultraviolet (UV) radiation. Although the process generates some metal fumes, it's generally considered that the generation of fumes is not as high as in other welding methods.

The shielding effect of the flux minimizes the amount of fume released during the welding, leading to relatively low concentrations of metal fumes compared to processes that are more open. However, the UV radiation generated by the arc can lead to skin burns or eye injuries if proper protective equipment is not worn. This makes awareness of potential UV exposure crucial for welders, as it can occur even in the presence of shielding.

The other options highlight different hazards that, while relevant in welding contexts, do not accurately capture the primary risks of submerged arc welding. For instance, high levels of carbon monoxide are not typically associated with this welding technique, as most of the gases generated during the process differ from those in methods that involve a more open flame or arc. Additionally, excessive heat and steam, while present in any welding process, are not specifically highlighted as significant hazards in
