Latest Patents
One of his latest patents is for an "Induction heating pressure welding with rotary bus bar joint." This invention discloses a method and apparatus for induction heating weldable surfaces and moving the heated surfaces together with sufficient force to upset the surfaces while in a substantially inert atmosphere, thereby welding the surfaces together. The apparatus includes a rotary bus bar joint for moving the induction coil between the weldable surfaces and features a clamping mechanism for handling members with different sizes and shapes.
Another significant patent is the "Dual induction heating pressure welding apparatus having a control." This invention involves a welding control circuit for induction heating a pair of articles to a welding temperature and pressing the heated articles together. A pair of induction coils are positioned in a gap between the articles to be heated, and temperature sensors monitor the temperature of both articles, controlling heating rates to ensure they reach welding temperature simultaneously.
