A welding process utilizing the concentrated heat of an electric arc to join metal by the fusion of the parent metal and any filler metal added to the joint, usually in the form of a consumable electrode or, for nonconsumable electrode processes, as an auxiliary wire. This discussion of the arc-welding process is divided into five general subjects: kinds of welding current, methods of welding, arc-welding processes, types of arc welders, and classification of electrodes. Figure 1 presents a fundamental arc-welding circuit, and Fig. 2 shows the elements of the weld at the arc from a covered metal electrode. For the metallurgical aspects of welding See also: Welding and cutting of materials
