Abstract
We propose a configuration of D-branes welded by analogous orbifold operation to be responsible for the enhancement of gauge symmetry in type II string compactified on the -type singular limit of K3. Evidences are discussed from the -type ALE and D-manifold point of view. A subtlety regarding the ability of seeing the enhanced gauge symmetry perturbatively is briefly addressed.
