Abstract
Data on electron beam weldability of iron-nickel alloy 32NKA of the type of Invar are presented. Parameters for welding different types of the joints for the fabrication of thin-walled shell structures have been optimised. Chemical composition, mechanical properties, microstructure, density, hardness and chemical heterogeneity of welded joints have been investigated. X-ray diffraction analysis of the recrystallisation zone has been conducted. Recommendations on the use of electron beam welding for the commercial fabrication of welded structures are given.
Keywords: electron beam welding, weldability, electron beam, nickel alloy, mechanical properties, microstructure, thinsheet shell
