Abstract
A self-cleaning GMAW nozzle characterized by the inner surface thereof having a laminate group, preferably composed of sequentially alternating layers of metal and bonding material. Over a period of time of welding, welding spatter begins to accumulate upon an outermost metal layer of the laminate group. As the heat of welding proceeds over this same time, the adhesion of the adjoining bonding layer releases, whereby the outermost metal layer detaches, exposing a clean, new outermost metal layer. The process sequentially repeats until all metal layers have detached.
