Abstract

PURPOSE: To let the captioned welding be effectively performed by increasing or decreasing the travelling speed of a track by signal of the inclination degree detecting device provided to the welding device which self travels along the inside circumferential surface of a cylindrical body and includes the truck.
CONSTITUTION: A controller 17 receives the signal from a rotary generator 16 and the signal from a comparator 18 and controls and drives the drive motor 15 of a truck 9. An inclination degree detector 21 detects the angles of inclination of torches 12, 12' in their welding advancing direction and the signals thereof are amplified in an amplifier 19 and are charged to the comparator 18. The comprarator 18 compares the signals of the detector 21 and inclination angle setter 20 and gives a command to the controller 17 of the truck drive motor 15. The truck 9 is then started together with a turning roller device 6 and is driven while maintaining the preset degree of inclination to ground. Hence the welding speed is readily determined and accurately maintained by independently setting the number of revolutions of the turning roller. The torches 12, 12' perform fillet welding by sandwiching the ring body 2.
