Abstract
The direct metal lamination is one of the additive manufacturing processes using the arc welding technology; where the molten metal made by the arc discharge is accumulated successively in this process. In this study, two kinds of dissimilar metal fabrication were conducted. One combination is an aluminum alloy and a titanium alloy. Another is a stainless steel and a Ni based alloy. The boundaries of dissimilar metal structures were investigated. As a result, the potential of the fabrication with more than one kind of metallic material by direct metal lamination is shown.
