ABSTRACT:
The apparatus of the invention employs a gas torch which has the feature of selective addition of metal powder to the gas flow. In use, the torch is caused to make a continuous succession of traverses of a workpiece region for preheating purposes and then, without interrupting the continuous operation of either the torch or the traversing cycles, a controlled flow of metal powder is caused to enter the torch flow, enabling the bonding and progressive building of a metal coat to desired thickness. In the embodiments described, first and second different metal powders are thus successively coated to the substrate without interrupting the continuous operation. Different embodiments are described in the particular context of applying uniform circumferential coatings to a cylindrical workpiece such as a shaft.
