ABSTRACT:
Workpieces which are formed by the build-up of weld metal are treated and cooled by directing a fluid such as water in a large stream so that rapid and intensive cooling of the surfaces of the workpiece is achieved by creating a laminar water flow. A water quantity is directed to reach the workpiece surface in a laminar flow and it is permitted to flow over the workpiece as the water is sucked off before it reaches its boiling point at the rate of flow to the workpiece and away from the workpiece being sufficient to prevent the formation of steam. The water which is employed is advantageously recooled to its initial temperature by the withdrawing effect created by an air fan.
