Abstract. Let graph G = (V,E) has V vertices and E edges. For every two different edges of graph G has total irregularity strength labelling ofG ifωt(e) ≠ ωt(f) where graph G = (V,E) has V vertices and E edges. The weight edge ofxy of a graph G is 𝜔(xy) =𝜆x) +𝜆xy) + 𝜆y) where 𝜆x) is the label vertex x and 𝜆y) is the label vertex y and 𝜆xy) is the label edge of the xy. The minimum value on the biggest labels make a graph G, has irregular labeling which is defined as total edge irregularity strength and denoted by tes(G). In this article, The total edge irregularity strength of diamond ladder graph and
the union of diamond ladder graphs (isomorphic) are determined. The diamond ladder graph, denoted by Dln, is a graph consisting ofn diamond (n ≥2) .

Key Words : Total edge irregularity strength, Diamond Ladder Graph (Dln)
