Abstract
This paper made it clear that ultrasonic examination and the method of monitoring voltage and current can be applied to manage the tensile shear strength of welded joint,paying attention to the following items.<br>In case of ultrasonic examination by using the rubber sheet on spot weld surface in immersion technique,the porish treatment of indentation affects the measurement accuracy.<br>In using AC spot welding machine and applying the method of monitoring voltage and current, we must calculate the resistance which contribute heat generation from measured voltage and current by eliminating the influence of inductance.
