Special features of the physical–chemical processes of interaction of refractory metals in electron beam welding

Abstract

Refractory metals' interaction physical–chemical process features are investigated in electron-beam welding to obtain a qualitative weld in a wide range of welding conditions. Dependence of the welded strength on the presence and thickness of the intermetallide interlayer is established.
