Latest Patents

Fastritsky's latest patents include an innovative apparatus for non-destructive testing of spot welds. This invention utilizes high and low-frequency electromagnetic fields to induce eddy currents in the weld zone. The difference in phase values of the resultant electromagnetic field intensities serves as an indicator of weld quality. The apparatus comprises an eddy current transducer, high and low-frequency measuring channels, an indicator, and a controlled commutator for alternating connections. Additionally, a memory unit is included for storing output signals, while a comparator is used to analyze these signals for quality assessment.

Another significant patent involves a method for non-destructive quality testing of spot welds. This method generates a primary electromagnetic field that induces eddy currents in the weld nugget region. The primary electromagnetic field is then displaced parallel to the surface of the welded parts. The phase angle between the resultant and primary magnetic fields is measured, allowing for the evaluation of weld nugget thickness and diameter based on the intensity of the electromagnetic fields.
