: Photograph shows shielded metal arc welding, informally known as stick welding, which uses an electric current to form an electric arc between the electrode and the metals to be joined. The welder is wearing standard personal protective equipment including heavy leather gloves, a long sleeve jacket, and a welding helmet.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld.
