The spot welding process described in Chapter 11 is not suited to all welds, especially long-path joints needing a gas-tight seal between the two surfaces being joined. However an alternative electric welding technique exists for such situations in the form of electric arc welding. In this process the heat required to fuse the metal surfaces together is derived from an electric arc. This is no more than a sustained ‘spark’ or electrical discharge between two terminals, which in this case are the work and a metal welding electrode.
