Latest Patents

Reinhard Opitz holds a patent for a "Process for welding cast iron." This patent describes an improved friction-welding process that effectively creates a joint between steel and nodular graphite-containing cast iron. The process utilizes a short friction-generating time to minimize the diffusion of carbon into steel, along with an elevated forging pressure to ensure the quantitative ejection of carburized melt while avoiding the formation of a weld laminate. The patent also details a nodular graphite-containing cast iron of grade 40.3 S, which is suitable for use in friction-welding and comprises approximately 280-320 graphite nodules per mm², 280-300 ferrite grains per mm², and a spherulite proportion of at least 95% by weight of the graphite precipitations.
