-In the article the experimental study of influences of laser beam profiling on the microstructure of the material obtained by selective laser melting is presented. Microstructure was researched by the example of single-track formation. For these needs the optical and video-monitoring stand was constructed. The defects of single-track formation were obtained by microscopy and video monitoring. The technological gaps for each laser beam profile give the possibility to use higher power for laser systems in the future with the purpose to improve productivity of SLM processing.

-The research of possibility for production of the thin-wall structure as separator for nuclear needs from electrolytic chrome by electrical discharge machining is shown in this article. The developed technology gives an opportunity to obtain a part with minimal allowance. The machined samples were researched for their defects and their surface depletion.
