An arc from an electrical discharge is used at least to heat a metal workpiece. Most of the patents in this collection are directed to metal fusion welding wherein the heat of the electrical arc discharge is used to melt metal, producing the weld between metal workpieces. Others discuss cutting a metal workpiece using the heat from an arc discharge. Others deal with effecting a metalurgical treatment using an arc.
