Latest Patents

Wisler's latest patents include innovative solutions such as the "Surface Smoothed Tool Joint Hardfacing." This invention features a tool joint hardfacing that incorporates sintered tungsten carbide granules embedded in an alloy steel matrix. The design ensures that the surface is substantially free of protruding granules, which helps decrease casing wear during well drilling. The hardfacing is applied in a single application by rotating the drill pipe, creating an arc between a consumable steel wire and the pipe to form a weld puddle. The process involves reciprocating the wire parallel to the pipe axis to create a band, with the tungsten carbide granules being gravity fed directly into the arc to provide a smooth surface.

Another significant patent is the "Heat Treatment of Welds," which describes an apparatus for heat treating the weld and heat-affected zone between a steel pipe and a steel connector. This apparatus includes an induction coil that heats the weld and the surrounding area to a selected temperature. Additionally, a ring-shaped manifold directs gas flow against both the interior and exterior of the weld, enhancing the heat treatment process.
