Abstract:
A friction stir welding apparatus includes: a thermocouple and a temperature measurement device which are configured to detect a temperature of the temperature measurement point; a temperature monitor configured to calculate an estimated temperature of the welding tool from the detected temperature of the temperature measurement point, based on a predefined correlation between a temperature of the welding tool and a temperature of the backing member; and a controller configured to perform a predetermined procedure based on the estimated temperature of the welding tool so as to prevent overheating of the welding tool.
