Abstract

PURPOSE: To permit high quality welding by controlling the position of molten pool by measurng the temperature near molten pool of the right left walls by means of a temperature sensor and by moving the welding torch and the measuring instrument according to the measured temperature difference.
CONSTITUTION: During welding, the temperature near the molten pool of the right and left walls of the bevelings 1 and 1' is measured by using the temperature sensors 4 and 5. If the welding torch, or molten pool, is deviated rightward from the center of the bevelings 1 and 1', the measured value by the right sensor 5 become higher than that by the left sensor 4. The both measured values are put in the differential amplifier 6, and the output therefrom is then put in the motor driving signal generator 7. The output of the generator 7 is amplified by the amplifier 8 and then applied to the driving device, or motor 9. Thus, the motor moves the welding torch to the direction in which the measured values of temperature on the both wall sides of the beveling become equal. With this profile control, high quality welding can be secured.
