Welding is the process of joining materials, usually metals, by applying heat and pressure.
Welding Helmet
A Welding Helmet is a protective safety equipment used by welders to protect the eyes, face, and neck from harmful radiation, sparks, and heat generated during welding operations. It is equipped with a darkened filter lens that shields the eyes from intense light and ultraviolet/infrared rays. Modern helmets may include auto-darkening features for better visibility and convenience.
