Embodiment Construction

[0024] In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.

[0025] A thin-walled casing process window welding process, comprising the following steps:

[0026] step one, as Figure 1-2 As shown, determine the welding workpiece of the process window, including the casing 1 with the process window 2, the patch block 3, the anti-deformation tooling 4 and the assembly tooling 5;

[0027] Step 2, determine the welding groove of the process window 2, the groove angle of the process window 2 is 45-55°, the groove angle of the patch block 3 is 30-40°, the groove of the process window 2 and the groove of the patch block 3 are clamped. The angle is 80-90°;

[0028] Step 3, insert the anti-deformation tooling 4 between the outer ring and the inner ring of the casing 1, the surface of the anti-deforma...

Abstract

The invention discloses a thin-wall casing process window welding process which comprises the steps that an anti-deformation tool is inserted between an outer ring and an inner ring of a casing, the surface of the anti-deformation tool is attached to the inner wall of the outer ring, the anti-deformation tool and a process window are correspondingly arranged, and an assembly tool fixes a patch block and places the patch block into the process window. The patch block and the process window are fixed in a spot welding mode, the assembly tool is dismantled, the patch block and the inner wall of the process window are welded in a single-pass welding mode, argon is introduced into the back face of the process window during welding, and the anti-deformation tool is taken down after the position to be welded is cooled to the room temperature; the inner wall of the outer ring of the cartridge receiver is supported through the anti-deformation tool to prevent deformation, the patch block is clamped and fixed by clamping the patch block through the assembly tool, the patch block is welded and fixed to the outer ring of the cartridge receiver in a spot welding and single-pass welding mode, deformation caused by welding stress is effectively controlled, the quality of an outer pipe on the welded surface is improved, and the service life of the outer pipe is prolonged. The production operation is convenient, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of casing welding repair, in particular to a thin-wall casing process window welding process. Background technique [0002] In the field of aero-engines, engine casing castings are often complex in structure, irregular in shape, require high dimensional accuracy, and are extremely difficult to cast. like figure 2 As shown, the receiver will leave a process window on the outer ring according to the needs during production, and the process window needs to be sealed and welded in the later stage of the production of the receiver. The existing thin-wall casing process window requires two people to cooperate in the operation, the size of the welding seam is greatly deformed, the size of the wrong side is difficult to control, the appearance quality of the welding seam is poor, and the welding efficiency is low. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a thin-wa...
