<P>PROBLEM TO BE SOLVED: To provide an angle adjusting device which does not require any high welding skill, when welding an end of a pipe to the side part of another pipe. <P>SOLUTION: The angle adjusting device 10 includes: a pipe holding part 20 holding a welded object 50; a first adjustment mechanism 30 rotating the pipe holding part 20 around an rotation axis A1 to gradually change a direction of a first pipe 51; and a second adjustment mechanism 40 rotating the pipe holding part 20 around a center line A2 of the first pipe 51 to change a direction of a second pipe 52. As the direction of the first pipe 51 gradually changes from one arrangement of a lengthwise direction arrangement and a crosswise direction arrangement to the other arrangement, the second adjustment mechanism 40 adjusts such that the direction of the second pipe 52 becomes near a horizontal direction H in the crosswise direction arrangement as compared with in the lengthwise direction arrangement, and gradually changes the direction of the second pipe 52 to one direction during change from the one arrangement up to the other arrangement. <P>COPYRIGHT: (C)2013,JPO&INPIT |
