... welded; weld quality in most metals is equal to or superior to that produced by gas tungsten arc welding (GTAW). Because the total kinetic energy of the electrons can be concentrated onto a small area on the workpiece, power densities as high as 10 8 W/cm 2 (10 7 W/in. 2 ) can be achieved. That is...

... induction furnaces. The arc furnace is the primary melting method and is used by over 80% of steel foundries ( Ref 1 ). However, arc furnaces are not good holders or efficient at superheating metal, so it is not uncommon to use induction furnaces to superheat steel after the arc melters. Induction furnaces...
