Features of chromium filler melting depending on laser radiation puls shape in welding and surfacing processes

Abstract

Laser technologies are becoming ever wider applied in modern industry in welding and surfacing of metals. Here control of filler material heating and melting, its transfer and formation on the item is important. Laser radiation shapes for filler material melting and transfer with its minimum evaporation have been established with application of mathematical modeling of thermal processes. Pulse front parameters are determined, which ensure minimum energy consumption for heating and melting of chromium filler. Obtained results can be used in development of procedures of pulsed laser welding and surfacing of metals and alloys. 8 Ref., 1 Table, 9 Figures.
