The process of fusing one metal to another using combustible gas, covered electrode arcs, and gas-shielded arcs; welding exposes welders to gases, metal fumes, and toxins, and increases risk of lung cancer and mesothelioma


n a process used to join metals.
welding, arc and gas,
n See welding, fusion.
welding, cold,
n the property of welding at room temperature when clean surfaces are pressed into contact. This property is exhibited to the highest degree by gold in the form of foil or crystals.
welding, fusion,
n a process in which parts are melted and fused together. Also called
arc and gas welding.
welding, pressure,
n a welding process in which the parts are not melted, although heat is usually required. Recrystallization across the interface occurs. Gold foil is welded by pressure without temperature elevation. Also called
resistance welding and
spot welding.
welding property,
n the characteristic of certain materials, especially metals, to firmly unite together when subjected to heat or pressure in a suitable environment.
welding, resistance,
n See welding, pressure.
welding, spot,
n See welding, pressure.
