In this article we prove that for a large class of 2-dimensional minimalcones (including almost all 2-dimensional minimal cones that we know), thealmost orthogonal union of any two of them is still a minimal cone. Comparingto existing results for minimality of almost orthogonal union of planes\cite{2p,2ptopo}, here we are dealing with unions of cones with non isolatedsingularities, which results in a series of essential difficulties, and newideas are required. The proof in this article can be generalized to other typesof minimalities, e.g. topological minimality, Reifenberg minimality, etc..
