Electron beam welding (EBW) is a high- power- density beam welding method generally recongnized as a useful production joining process. Recently, on the viewpoint of weight reduction of a vacuum chamber, stainless steels have been being takentheir places by thick aluminum alloys. EBW are used to assemble it. This report summarizes the principle of EBW and current researches for weldability and structural and mechanical properties of welded thick aluminum alloy joints. Moreover, some examplesof EB welded aluminum component are introduced as the industrial application.
