#$%^&*AU2014201160A120140327.pdf#####Abstract A welding accessory and a system for detecting thermal and/or UV radiation exposure during welding operations are disclosed. The welding accessory may have a surface exposed to thermal and/or UV radiation generated by electric arc welding, a first image visible without exposure to the thermal and/or UV radiation, and a second image formed from either a UV activated dye that is visible only after exposure to UV radiation generated by the electric welding arc or a thermochromic dye that is visible only after exposure to a predetermined level of thermal radiation generated by the welding arc. A system may include either a thermal or UV exposure indicator with a first state and at least a second state, and include either a thermochromic or UV activated dye adapted to provide a reversible or persistent visual indication upon exposure to radiation. The visual indication may include any combination of symbols, logos, images, text, or other decorative or informational designs as desired.12 22 12 28 u 22 24 -~E' I G. 4
