Machining process of low-deformation aluminum alloy welding aviation part

Abstract

The invention provides a machining process of a low-deformation aluminum alloy welding aviation part, and belongs to the technical field of welding. The machining process of the low-deformation aluminum alloy welding aviation part comprises the following steps that S1, shape correction is carried out, specifically, burrs on the four sides of a cover and a box body are removed thoroughly through ascraper or a file, the four sides of the cover are knocked inwards through a small hammer to be slightly bent inwards to be in an arc shape, the four fillets of the cover and the four fillets of the box body are shaped to be consistent in transition, and the cover and the box body are matched free of dislocation; S2, cleaning is carried out, specifically, the portions, needing to be welded, of thecover and the box body are wiped clean with acetone; S3, clamping is carried out, specifically, the box body and the cover are placed into a tool, after the box body and the cover are placed in place, the box body is opened from inside to outside and in contact with the cover, and the welding edge of the box body is in close contact with the welding edge of the cover; S4, primary welding is carried out; S5, machine welding is carried out; S6, repair welding is carried out; and S7, part taking is carried out. The machining process has the advantages of being small in deformation during weldingand good in welding sealing performance.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to a processing technology for welding aviation components with low deformation aluminum alloy. Background technique [0002] Aviation parts are relatively precise and precise parts. During the processing process, there are strict size requirements, and the processing technology is different from the traditional processing method, and the requirements are even higher. [0003] The functions on the aircraft are becoming more and more diversified. Various boxes for accommodating objects need to be installed on the aircraft. The sealing and size of the boxes are also strictly regulated. Severe deformation of parts and insufficient sealing. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a low-deformation aluminum alloy welding aviation parts processing technology, which has the c...
