Abstract
The results of works on increase of life of fixture of forging-press equipment by application of electric arc surfacing using electrodes and flux-cored wires are given. It is preferably to create and apply the specialized flux-cored wires, providing high life of deposited metal by optimization of its alloying. It is shown that application of restoration surfacing considerably increases the cycle between the repairs during operation of press strikers and provides economic effect of equipment service. 8 Ref., 5 Figures.
Keywords: arc surfacing, parts of die equipment, restoration and strengthening, flux-cored wire, extension of life
