Managing Welded Joint Formation at Electron-Beam Welding of Aluminum Alloys of Increased Thicknesses

Аннотация

Abstract—The technology of electron beam welding of homogeneous and dissimilar welds of aluminum alloys 1561, 1560М, and 1980T1 has been developed. Beam scanning along the semielliptical trajectory has secured the quality of the welded parts with fine mechanical properties. The welding scheme and optimal modes have been determined. The results of mechanical and corrosion tests, as well as the results of the delayed failure tests, are presented. The technology is implemented for hydrofoil devices and for the manufacture of shipbuilding machinery components.
