Title: Innovations by Robert C Hardt in Welding Technology
Introduction
Robert C Hardt is an accomplished inventor based in Country Club Hills, IL (US). He has made significant contributions to the field of welding technology, holding two patents that showcase his innovative approaches to welding processes.
Latest Patents
One of Hardt's latest patents is a welding process that utilizes upright noncoaxial orbital transverse motion. This improved welding technique involves two metallic pieces composed of weld-compatible parent metal. The process includes applying a force along the longitudinal axis of the metallic pieces to position prominences for abutment. Additionally, a force is applied transverse to the longitudinal axis of one metallic piece, allowing for relative movement and displacement of the cross sections. This method also incorporates electrical current to elevate temperatures through electric resistance heating for thermal-fusion welding.
Another notable patent involves a welding process with parent metals that are incompatible during heating. This process includes aligning surfaces to overlie one another and positioning a gap between them, filled with a surrogate electrically conductive piece. The method applies force along the longitudinal axis of each metallic piece and through the surrogate, providing electrical resistance heating. After ceasing the force on the surrogate piece, the surfaces are encapsulated with an inert gas, followed by the removal of the surrogate piece and thermal-fusion force welding of the two metallic pieces.
