Patents by Inventor Nathan Messerich

Nathan Messerich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240055707
    Abstract: A method of forming a brazed joint is described. The method includes pressing a non-molybdenum component, such as a cross pin of a battery case assembly, against a molybdenum component, such as a terminal pin of the battery case assembly, and applying one or more electrical pulses to form an interface liquid layer between the components that cools to form the brazed joint. At least one of the electrical pulses has a constant voltage over a pulse time. A contact resistance between the components can decrease during the pulse time, and thus, the constant voltage can cause an uncontrolled electrical current of the electrical pulse to increase. The increasing electrical current heats the components sufficiently to form the interface liquid layer having a predetermined thickness that provides a required bend strength. Removal of surface oxides provide consistent mechanical strength for this joint. Other embodiments are also described and claimed.
