Abstract
The electric arc surfacing of wear-resistant layers on sheet structures of less than 4 mm thickness is connected with a risk of occurrence of burn-outs and excessive deformation of sheets due to their high penetration. One of the possible ways to decrease penetration is the selection of an optimum method of surfacing and development of appropriate technologies and surfacing materials. It was experimentally found, that to provide a minimum penetration with account for a quality formation of deposited metal is possible by using the open-arc surfacing with a flux-cored wire of less than 1.6 mm diameter. The application of the developed technology and technique of surfacing using an improved self-shielding flux-cored wire PP-AN198 provided a quality formation of the deposited metal, absence of burn-outs, pores and other defects, as well as reduced the residual deformations in surfacing of sheets of 3 mm thick steel St3 to minimum. The obtained results can be used in selection of surfacing materials and technologies for surfacing the wear-resistant layers on thin-sheet structures, which are operating in mining and metallurgical industries under the conditions of different types of abrasive wear. 8 Ref., 1 Table, 3 Figures.
