Title: Arthur M. Filippi and the Seal-Welded Cast Iron Nuclear Waste Container.

Introduction

Arthur M. Filippi is an inventor associated with Pittsburgh, Pennsylvania. His work includes a patent for a nuclear waste container designed to address the challenges of welding cast iron.

Latest Patents

Filippi is credited with 1 patent, titled “Seal Welded Cast Iron Nuclear Waste Container.” The invention describes a method for hermetically closing an all-cast-iron nuclear waste package while limiting the metallurgical problems caused by welding.

The design uses nickel-carbon alloy inserts bonded to the package’s plug and main body. These inserts may be incorporated during casting. During closure welding, they confine the most severe thermal effects to material better able to withstand them than cast iron, potentially avoiding the need for difficult pre-weld and post-weld heat treatments. The patent also explains that the materials’ relative surface areas, electrochemical relationship, and shared graphite content are intended to help prevent galvanic corrosion.
