Introduction

Ryan Matthew Cullan is an inventor associated with Tewksbury, Massachusetts. His patent work addresses friction stir welding, a process for joining metallic plates and producing large components.

Latest Patents

Cullan is associated with 1 patent, titled “Friction Stir Welding Process for Large Metallic Components.” The invention describes positioning two metallic plates so their faying surfaces meet, then attaching a backing plate across the joint. Friction stir welding joins the plates, with the backing plate receiving the end of the welding tool. After welding, the backing plate is removed, and the resulting blank is formed into a component and heat treated and aged. The process is designed to maintain a stable weld microstructure with little or no abnormal grain growth during elevated-temperature forming, heat treatment, and aging.
