Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV

First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on {\pi}+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.Comment: 29 pages, 20 figure

Investigation of the effect of waterjet cleaning on the quality of welding

On the example of welding 3SP steel, the features of the hydroabrasive (EPS) cleaning are shown. The formation of the weld, its structure and properties, the formation of macro- and microgeometry of the heat-affected zone are described. The influence of welding parameters on ensuring the necessary quality and properties of steel is considered

Research of a laser welding of thin-shit construction steels by continuous laser radiation

© 2019 IOP Publishing Ltd. All rights reserved. The results of the laser welding by continuous radiation of thin-sheet low-carbon steels on the example of steel 08U presented in this paper. Metallographic studies of the laser weld were conducted. Tensile tests were carried out as a result of which it was determined that the nature of the fracture is adhesive, and after cohesive failure of the specimens, it is show the high quality of the welded joints at the beginning of the weld
