Method of resurfacing (hard-facing), by welding, the working surface of dies which are intended for the forging of shaped mouldings

摘要

For the development of a method for resurfacing the working surface of dies intended for the forging of shaped mouldings, which does not involve significant expense and, at the same time ensuring long service life times, enables the dies to be reused many times, the recommended solution includes the following operations: … …  - hollowing out the die over the entire working surface to a depth for which the supply of build-up (facing) metal up to the set-point level of the working surface can be carried out over a thickness such that the working surface is constituted by pure weld filler metal; …  - resurfacing of the die up to a little above the set-point level of the working surface; …  - machining the set-point contour of the working surface. … … IMAGE …
