Abstract
The paper presents the results of studying mechanical properties of joints of 1460 alloy and joints of 1460 + 1201 dissimilar alloys, produced by EBW at room and cryogenic temperatures. It is shown that the strength of joints of 1460 alloy, welded using filler material from 1201 alloy at a temperature of 77 K rises by 10 %, and at a temperature of 20 K — by 20 % as compared to the joints welded without using filler material. Mechanical properties of welded joints of 1460 + 1201 dissimilar alloys at the test temperatures of 20, 77 and 293 K are on the level not lower than those of the joints of 1460 alloy, welded with the application of 1201 filler material. Welding technology is described and chemical composition of weld metal is given. 12 Ref., 3 Tables, 9 Figures.
Keywords: electron beam welding, aluminium-lithium alloys, filler material, mechanical properties, welded joints, cryogenic temperatures
