Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 The object of research - point connection obtained using pulsed laser technology, laser contouring and arc spot welding consumable electrode. Tsel work - comparison of the structure and properties of the weld point of high-alloy steels obtained using laser technology and arc spot welding consumable electrode. Metody research - analysis the scientific literature on these issues, the development of design documentation and making the necessary tooling, experimental studies point to obtain compounds of high-alloy steels with laser and arc spot welding consumable electrode, a comparative analysis of the structure and characteristics of the resulting weld, the analysis of the characteristic patterns of defects and development measures for their elimination. In the course of work found that the point of connection of steel ЭП679 ВД and 12X18H10T obtained using pulsed laser technology, laser contour arc and spot welding consumable electrode, are the equilibrium structure of the weld and heat affected zone with microhardness 2320. .. 2520 MPa at the level of the base metal. However, with all kinds of welding observed with microhardness at 1300 MPa and discharge up to 25 microns with a high content of alloying elements Mo (up to 31,45%), Ti (to 80.1%). Allocating a large percentage of the alloying elements are observed in laser welding process on a path that is associated with a highly concentrated making heating energy compared to arc welding and higher cooling rate of the weld metal. When comparing the mechanical properties revealed that the connection point obtained contour laser welding have the greatest resistance values of shear at 530-540 MPa and a form of execution is a promising point connections in the production of honeycomb sandwich structures. Projected assumptions about the development of the object of research - use the results to create on their basis of technology and automated systems for laser welding of large sandwich products from thin structural elements.thin-walled structural elements.
