Abstract
An apparatus and process are provided for scan induction heating of a workpiece. The workpiece is moved through an inductor to inductively heat treat features of the workpiece with electric power of varying frequency and duty cycle to control the magnitude of electric power as the frequency changes. Alternatively the inductor is moved along the workpiece to inductively heat treat features of the workpiece with electric power of varying frequency and duty cycle to control the magnitude of electric power as the frequency changes, or a combination of simultaneous inductor and workpiece movement may be used.
