Latest Patents

Ohara holds a patent for a "Method for checking a spot welded portion and spot welding machine." This invention allows for the detection of a decrease in plate thickness at a spot weld during a predetermined time period after the power supply to the electrodes has been terminated. The decrease in thickness is correlated with the diameter of the nugget formed during the welding process. A larger nugget diameter indicates a stronger joint, enabling quality assessment based on the detected decrease in thickness. The invention includes a detector that measures the stroke position of a cylinder pressing the electrodes, allowing for indirect detection of plate thickness without compromising the efficiency of the welding operation.
