Arc Welding: Heat is generated by an electric arc that raises to the
proper temperature the parts to be joined.
In some case no filler material is used; the parts are simply fused
together and become one.

Arc welding can be used successfully on what would otherwise be
difficult material to join, such as stainless steels and nonferrous metals.
