[0002] The flame tube is an important component in the combustion chamber part of an aero-engine, and is connected by welding in a ring-shaped structure formed by multiple thin plate high-temperature materials. Finally, it is connected with a machined part at the end, and a joint flame pipe is welded near the end of the main body. The angular position of the joint flame pipe and the dimensional accuracy of the end face to the center of the flame tube have a direct impact on the assembly of the flame tube. Therefore, how to control and ensure the size requirement is particularly important.

[0003] The angular position can be controlled by the corresponding welding special tool during welding, but the size of the end face of the joint flame pipe to the center of the flame tube can only be processed after leaving a margin on a single piece.
