Abstract

PURPOSE: To achieve the rationalization of internal circumferential surface welding of pipes by letting the carriage for internal circumferential surface welding of pipes having the welding device which is movable overhead and downward or up and down travel over the entire circumferential surface.
CONSTITUTION: The support devices 8 of the travelling carriage which welds the butted inside circumferential surfaces of pipes are constituted by twin-legged poles 5, 5, freely revolving shaft 6, arm rod 7, and pressing device 9 and are supported by these. A welding carriage 4 is mounted to end of the arm rod 7 and may be run along the inside circumferential surface of the pipes by positive drive wheels along the circumference. Because of this, if the welding torch of the welding truck 4 is aligned to the groove line 2, the correct welding along the inside surface groove 2 is continued. At the time of making combined use of various welding methods, multiple kinds of welding heads are provided to the carriage 4 and are used alternately. If the welding of inside surface groove of one place is completed, the pressing device 9 of the stand is opened and the carriage moves as transfer carriage to the next welding position.
