Abstract

The basic regularities and ways of optimizing the production of welded joints of Ti – TiB alloy plates and 12Х18Н10Т steel were studied. The ways to achieve the necessary mechanical characteristics of welded structures from elements with a thickness of 10 mm obtained by electron beam welding were found out. It was determined that electron beam welding of Ti – TiB alloy compounds with 12Х18Н10Т steel is effective when using a double strip of niobium and 10Г2 steel. It was found that in order to obtain welded joints of the Ti – TiB alloy with Nb electron beam welding, it is necessary to ensure the melting of the Ti – TiB alloy, conditions for wetting niobium with the obtained melt, and to prevent the formation of an intermetallic layer in the weld. It is shown that the welded joint Ті-TiB - Nb - 10Г2 - 12Х18Н10Т obtained by electron beam welding allows to achieve a strength level of at least σв = 260 MPa.
