This article studied the LEW (large edge width) embeddability of weighted grid graph G(a,b)(a≥2,b≥2) and the Mobius ladder graph Gn(n≥4) and showed that such two types of weighted graphs have no LEW-embeddings. Based on these two kinds of graphs weighted graphs were constructed which are strongly embedded in Sn and Nh and permit no LEW-embeddings in the same surface they embedded.
