Consumable
From GAWDAwiki
(Redirected from Consumables)
The term consumable refers to any material consumed during the welding process or within the weld itself. Welding consumables include wire, rod, tungsten electrodes, and shielding gas.[1]
Different welding consumables are appropriate depending on the type of welding and the material being welded.[2]
In MIG welding, the term consumables can also refer to replaceable parts within a MIG gun, including the nozzle, contact tip, liner and retaining head (also called a diffuser). [3]
