Shielded metal arc welding (SMAW), also known as stick welding, is a manual welding process that uses a consumable electrode covered with flux to lay the weld. Personal protective equipment used in welding includes welding jackets, auto-darkening helmets, gloves, and shoes to protect welders from heat, sparks, radiation, and falling objects, as well as aprons, leggings, and face masks to shield the body from molten metal and fumes. Safety measures are crucial in welding to prevent injury to welders.
