Comparative analysis of performance characteristics of nozzle heads for powder transportation in a laser cladding and direct material deposition

Abstract

The analysis of the dynamics of gas-dispersed flows created by nozzle heads, which are used in the additive technology of direct laser deposition of material in the manufacture of metal products of complex geometry, is analyzed. The features of using nozzle systems for increasing the efficiency of powder transport in laser treatment are discussed. Typical gas-powder transport nozzles of well-known manufacturers Trumpf and Precitec are considered. The study is conducted to obtain additional information for a thorough understanding of the physical processes that take place and to increase the efficiency of the practical use of equipment.
