Abstract: A process for creating a support means for a component part of a usually complicated configuration that is to be reworked and/or repaired, by surrounding the surfaces of the component part that are to be supported by a meltable alloy which, in the cooled state, supports said component, and by removal of the meltable alloy after the treatment of the component part by heating is characterized in that, before the pouring, cooling pipes are placed in the support area to be cooled during the treatment of the component part, with said cooling pipes, during the pouring process, being embedded by said meltable alloy. Thus, a support means is created that can be produced in a simple and rapid manner, for a component part having a complicated support surface, which can also be well cooled. A support means of this type is especially suitable as a welding device for a component part to be repaired which is to be repaired, for example, by micro-plasma build-up welding.
