Latest Patents
One of his latest patents is for elevated-temperature, plasma-transferred arc welding of nickel-base superalloys. This innovation allows for the repair of articles susceptible to strain-age cracking while minimizing welding heat input. The process involves heating the article to a temperature between about 1650°F and 2000°F in an inert atmosphere before using a plasma-transferred arc welder to vaporize a filler metal and deposit it onto the article, forming a weld overlay. Another notable patent is for a low electric D.C., low time rate polarity reversing arc welding method. This method enables direct electric current arc welding between an electrode and a workpiece surface at a current range of about 0.5-45 amps. The polarity is reversed at a low frequency, resulting in anodic cleaning of the workpiece surface.
