| description | The invention relates to an anti-deformation method for high-temperature brazing of a spray pipe, and belongs to the technical field of heat insulation of solid rocket engines. The method comprises the following steps: accurately measuring the outer molded surface of the inner wall and the inner molded surface of the outer wall of a part to obtain molded surface sizes; sleeving the inner wall on a tool mold, coating the outer surface of the inner wall with a red lead powder solution, then trying to assemble the outer wall, and confirming a non-fitting area of the inner wall and the outer wall; the outer wall is detached, and the outer wall is cut off in the non-attached area of the inner wall and the outer wall through an angle grinder in the generatrix direction; sleeving the cut outer wall on the inner wall, and removing redundant outer wall excess materials or newly added jointed boards; welding the cut part of the outer wall by using TIG welding or electron beams; disassembling the outer wall, and manuall |
