WebArc welding – also called stick welding – uses a different process. The welding rod is composed of two substances, a filler metal that melts into the weld and forms the bead, and a flux. The flux reacts to the heat to produce shield gas and slag. The gas and the slag left on the weld bead both protect the weld from oxidation until it can cool. WebOf the two basic FCAW processes, one is self-shielding and the other one uses __________ shielding gas. shielding gas. In GMAW, the arc is stabilized and the molten filler and …
