ABSTRACT:
The ultrasonic weld inspection method comprises transmitting an ultrasonic wave through the molten metal portion of the weld while the weld is being formed and determining if a weld defect is present in the molten metal. If no defect is detected in the molten metal, the welding process continues. However, if a defect is detected in the molten metal, the welding electrodes remain at that position until the defect has dissipated. In this manner, defects are removed from the weld before the weld metal solidifies.
