Latest Patents

Renfu Li's latest patents include "Methods and systems for detecting defects in welded structures utilizing pattern matching." This method processes ultrasonic response signals collected from various measurement locations along a weld to determine the presence of defects. The process involves filtering ultrasonic response signals to produce filtered response signals, calculating ultrasonic energy for each measurement location, and comparing these energies to identify potential defect locations. If the ultrasonic energy at a measurement location is less than that of adjacent locations, it indicates a potential defect. The presence of a defect is confirmed by analyzing fluctuations in ultrasonic energy at neighboring locations.

Another notable patent is "Methods and systems for classifying the type and severity of defects in welds." This method determines the type of defect by analyzing ultrasonic response signals from measurement locations along the weld. A trained artificial neural network processes the defect signal and proximity signals to identify the defect type and classify its severity. This innovative approach enhances the reliability of weld inspections.
