Title: William J Arbegast: Innovator in Friction Stir Welding Technology
Introduction
William J Arbegast is a notable inventor based in Rapid City, SD (US), recognized for his contributions to the field of welding technology. He holds a total of seven patents, showcasing his innovative approach to engineering and materials science.
Latest Patents
One of his latest patents focuses on friction stir welding as a rivet replacement technology. This invention provides an improved method and apparatus for joining aluminum alloy panels, specifically the 2090-T83 aluminum lithium alloy. The method involves preliminarily positioning two panels and skin panels next to each other, allowing a stringer panel to overlap a skin panel. A friction stir weld pin tool penetrates through one panel and partially into another, where the surrounding material is frictionally heated, plasticized, and joined until the faying surface is substantially consumed. In another embodiment, a tee-shaped structure is formed using friction stir welding to join three panels together, creating a contoured corner panel from the material of one vertical panel.
