Latest Patents

Ewasyshyn's latest patents include innovative methods and apparatuses for ultrasonic in-process monitoring and feedback of resistance spot weld quality. One of his patents describes a method that utilizes at least one transducer located in the electrode assembly, which transmits through a weld tip into an ongoing weld. This method analyzes the spectrum of ultrasonic waves to provide operators with critical information regarding the size, thickness, location, dynamics of formation, and overall quality of the spot weld. This approach represents a fundamentally new physical method for characterizing spot weld quality.

Another significant patent focuses on a method and apparatus for assessing the quality of spot welds. This invention features a two-dimensional array of ultrasonic transducers arranged with a delay line positioned adjacent to the weld surface. A layer of gel is placed between the delay line and the weld surface to enhance the quality of the ultrasonic waves emitted. The reflected waves are analyzed by a central processing unit, which calculates various factors contributing to weld quality, including the border of the weld nugget and the thickness of the welded material.
