His innovative approaches have advanced the technology used in welding processes, showcasing his expertise and dedication to engineering.
Latest Patents
One of Tishura's latest patents is an "Electromagnetic Power Drive for a Friction Welding Machine." This invention features a magnetic core that is immovably installed and carries a power coil connected to a voltage regulator. The design includes at least one pickup coil that connects to an integrator, producing voltage proportional to the actual value of the magnetic flux during friction welding. This system is coupled with a comparison means that utilizes two comparators to ensure precise control during the welding process.
Another significant patent is the "Method of Friction Welding." This method involves jigging parts made of materials with inherent Young's moduli coaxially. The parts are set to rotate with respect to each other under axial pressure that varies with a frequency inversely proportional to the lower value of the Young's moduli and the diameter of the parts. This innovative approach allows for effective heating and upset-forging of the components being welded.
