Latest Patents

Malcolm D Hannah holds 1 patent for his invention titled "Resistance welding." This method involves controlling the duration of a resistance weld by feeding a preprogrammed AC current to welding electrodes. The program includes an abrupt increase in welding current after a predetermined number of cycles. This allows the weld duration to extend into the high amplitude portion if the heat input has been insufficient. The voltage across the welding electrodes is monitored, and the peak voltage is detected. A reference voltage is derived by dropping the peak voltage by 2 - 20%, and the weld is terminated when the subsequent peaks fall to the reference voltage.
