Study of the solid state joining of additive manufactured components

Abstract

The additive manufacturing technologies are finding an increasing use due to their peculiarities. A limit that still hampers their massive application is the maximum dimension of the components than can be produced. This paper deals with the study of the joining process of additive manufactured parts. In particular, two different cases have been studied: i) Ti6Al4V parts made through electron beam melting joined through linear friction welding; ii) AlSi10Mg parts made through direct metal laser sintering joined through friction stir welding. The results obtained showed the feasibility of both the processes.
