Abstract

Abstract:
Aluminum’s unique properties, e.g. light weight, high strength, and resistance to corrosion, make it an ideal material for use in conventional and novel applications. Aluminum has become increasingly used in the production of aerospace equipment, automobiles and trucks, packaging of food and beverages. However it suffers from poor joint strength when welded by conventional fusion welding. In this investigation an attempt has been made to improve the welded joint strength through using of electron beam welding (EBW). Due to special features of EBW, e.g. high energy density and accurately controllable beam size and location, in many cases it has proven to be an efficient method for joining difficult to weld materials. In this paper, the effects of EBW parameters on the ultimate tensile strength (UTS) has been investigated, The experiments were based on one-variable-at-a-time (OVAT) method,
