For welding, filters are required to protect the eyes and face from harmful ultraviolet (UV) and infrared (IR) radiation, as well as intense visible light. Welding helmets or goggles with appropriate shade numbers, usually ranging from shade 9 to 13 depending on the welding process and amperage, are used. These filters help prevent eye injuries such as arc eye and ensure safe welding practices.
