Let G= (V, E) be a graph with p vertices and q edges. An injective function is an odd sum labelling if the induced edge labelling defined by for all uv in is a bijective function and . A graph which is odd sum labelling is called odd sum graph. We in this paper investigate on the graph for by joining with similar graph for and we call the graph to be a join of H graph. We prove that such a graph is odd sum labelling graph and also prove some properties connecting those graphs. We have also obtained the sum of the edges joining the graph
