Abstract

PURPOSE: To make product quality uniform and increase production speed by continuously measuring the temperature of the butt part during welding and controlling the welding current in such a manner that the temperaure thereof maintains a fixed value.
CONSTITUTION: The temperature of the weld zone is measured with a radiation thermometer 1 by way of an optical fiber 30 in a metal plate 12 formed to a rounded pipe shape and is compared with the reference voltage S corresponding to a reference temperature. The deviation value thereof is led to a PID circuit 3 and the output current of a power source unit 9 is controlled by the output thereof, whereby the welding temperature is kept constant.
