Classification and Technical and Economic Parameters of Welding Deposition Processes

Abstract

The paper presents the classification and technical and economic parameters of the welding methods grouped according to the physical principle of the applied heat source used to heating and melting the weld metal, which makes it possible to analyze and select the most rational process that meets the technological and economic requirements of modern production. The main indicator of the processes used for wear-resistant surfacing is the fraction of the participation of the base metal in the deposited layer. Technological methods for reducing the content of the base metal in the welded layer under single-layer cladding, including the use of controlled droplet transfer processes, and the possibility of alloying the weld metal by using powder materials such as wires and tapes are considered. The application of surfacing processes for repair and manufacturing industries is shown. The systematization allows to create a database for the automated method of designing technological processes for repair and wear-resistant surfacing of surfaces of various parts.
