ABSTRACT:
A continuous process for coating a series of workpieces with a metal coating comprises the steps of cleaning the workpieces with a high-pressure water system which utilizes particulates; isolating the workpieces in a non-oxidizing chamber; spraying the workpieces with a wet flux; inductively preheating the workpieces with a preheat induction coil; spraying a coating metal onto the surface of the workpieces; inductively heating the workpieces with a main induction coil; and continuously conveying the workpieces through each of the above steps.
