Mechanism of formation of the welded joint in electron beam welding of refractory metals

Abstract

Seam formation mechanism at electron-beam welding is studied to obtain serviceable and reliable welded joints of refractory metals and constructional alloys on the base of iron and nickel. An interaction process control possibility between refractory metal and steel by technical and power-producing parameters control is established.
