Inhibit the Porosity with Electron Beam Scanning Method in Welding LD10 Aluminium Alloy

摘要：

LD10 Aluminium alloy is becoming widely used in aeronautics and astronautics industries for the advantages of high specific strength and good mechanical property. Aluminium alloy is an active metal with low melting point and boiling point. The porosity is apt to occur in the processing of electron beam welding. In this article, the author investigated the influence of electron beam scanning welding parameters (scanning figure, scanning frequency, focus, and welding speed) on porosity. 10 mm thick LD10 Aluminium alloy were welded and then tested by X-ray inspection. The experiment results indicated that rational parameters would reduce the occurrence opportunity of porosity. Using the parameters of circle scanning, high scanning frequency, focus-out, and smaller welding speed, the porosity can be significantly reduced.
