Title: Robert B Herchenroeder: Innovator in Welding Technology
Introduction
Robert B Herchenroeder is a prolific inventor based in Kokomo, Indiana, with an impressive portfolio of 16 patents to his name. His innovations primarily focus on advancing welding technologies and materials, addressing critical challenges in the industry.
Latest Patents
Among his latest contributions is a patent for a shielding gas to reduce weld hot cracking. This invention utilizes an inert gas nitrogen mixture, which is effective in preventing weld hot cracking in superalloys that contain zirconium and/or boron. The gas mixture optimally comprises argon along with 2 to 8% by volume of nitrogen. Test data have shown excellent results when applying this shielding gas during gas tungsten arc welding of HAYNES 214 alloy, a material known for its composition of boron, zirconium, and minimal titanium.
Additionally, Herchenroeder designed a sacrificial insert for strand annealing furnace tubes. This innovative tube assembly shields the strand being annealed from the harsh conditions of the hot furnace atmosphere. The design incorporates a long, oxidation-resistant outer pipe and a shorter, easily removable inner insert, ensuring any residue from drawing lubricants collects within the insert, thus preventing blockage or corrosion of the pipe.
