Safety welding goggles are protective eyewear designed to shield the eyes from the intense light and heat produced during welding and cutting processes. They are an essential piece of personal protective equipment (PPE) for welders and other workers who perform tasks involving welding, cutting, brazing, or soldering.Welding goggles are typically made of a durable, heat-resistant material such as polycarbonate or glass, with a darkened lens that filters out harmful ultraviolet (UV) and infrared (IR) radiation. Some goggles may also have a shade number, which indicates the level of darkness of the lens and the level of protection it provides.
