Abstract
Comparative estimation of methods of manufacture of light stiffened panels of aluminium alloys is shown. Advantages of the electron beam welding process for manufacture of thin-walled panels from high-strength heat-hardened aluminium alloys are given. Technology of a single-sided welding of stiffeners of thin sheets and plates at ratio of thicknesses from 1:1 to 1:15 and higher is developed. It was established that the programmed heat input within the circuit of the electron beam scanning during welding is the most effective means of control of weakening and shape of penetration zone of T-joints.
Keywords: electron beam welding, scanning with a beam, aluminium alloys, stringer panels, stiffeners, weakening zone, T-joint, programming of heat input
