Latest Patents

Among his latest patents is a friction stir welding tool and welding method. This friction stir welding (FSW) tool includes a pin, a housing, and a shoulder. The pin is designed to extend through a joint line between the edges of two workpieces. It rotates to perform a FSW process that effectively welds the two workpieces together at the joint line. The housing is coupled to the distal end of the pin, allowing for rotation relative to the housing. The pin extends through a support surface of the housing, which contacts the inner surfaces of the workpieces during the FSW process. The shoulder surrounds the pin and is configured to rotate during the FSW process, ensuring that the workpieces are sandwiched between the shoulder and the support surface of the housing.

Another significant patent is a method of welding a workpiece assembly. This method involves positioning a flange adjacent to a web to create a workpiece assembly with an interface between a flange edge surface and a web side surface. The method includes constraining the flange and the web against movement while moving a plasma arc welding (PAW) torch along the interface. This process generates molten material that joins the flange to the web, showcasing Shemkunas's innovative techniques in welding.
