ELECTRON BEAM WELDING OF THICK-WALL SHELLS OF ALUMINIUM AMg6 AND M40 ALLOYS

E.G. TERNOVOJ and A.A. BONDAREV

E.O. Paton Electric Welding Institute, NASU, Kiev, Ukraine
 
 
Abstract
Results of investigations on EBW of 40-90 mm thick semi-finished products of aluminium alloys AMg6 and M40 are given. Optimal welding parameters were selected. Properties, microstructural peculiarities and hardness of the resulting joints were studied for horizontal and vertical welds. The EBW technology in fabrication of large-size thick-walled shells of aluminium alloys was developed and passed the industrial testing.
 
 
Keywords: electron beam welding, aluminium alloys, shells, longitudinal and circumferential joints, welding conditions, joint properties, hardness, microstructure, industrial testing
