Abstract

PURPOSE: To surely measure the temperature between pass and preheating temperature by remote operation, by watching with television camera wether the temperature sensor is touched with measuring part or not and controlling contact process temperature sensor seeing the picture area.
CONSTITUTION: The guide ring 9 is provided on the piping 8 and the travelling truck 10 loaded the welding torch 2, the wire guide 11, the temperature sensor 6 and the television camera 7, is placed on the ring 9 at the time of welding the joint of piping. The sensor 6 is dropped down until contacting with weld zone before welding is started. Temperature is measured judging proper contact by the picture area of the camera 7 and then, temperature is measured drawing the sensor 6 apart from the piping 8 to a fixed position by th driving apparatus 3, watching the picture area of the camera 7 when the temperature is reached suitable welding temperature of the next pass. By the above controlling method for temperature measurement, temperature of weld zone is able to accurately measure from remote place at the piping welding of neuclear reactor etc.
