Increase the thin-wall part combined-repair method of material reparation.
Background technology：
The working environment that the aviations large thin-wall parts such as engine crankcase, leaf dish are on active service is severe, and part is frayed, rushes
Hit, high-temperature fuel gas and the effects that cool-hot fatigue after be also easy to produce crackle, corrosion and abrasion equivalent damage.Due to production cost and period
It is required that there is an urgent need to realize the high-quality and high-efficiency reparation of damage parts using advanced recovery technique, extend its service life, reduces
More renew part, reduce great economic loss, shorten maintenance cycle, aviation large thin-wall parts recovery technique is increasingly subject to aviation
The attention of manufacturing enterprise and maintenance company.
For crackle, corrosion and abrasion equivalent damage, need to carry out polishing cleaning before reparation, such as by polishing crackle and surface
Oxide completely removes, and forms to be repaired area of the shape with respect to regularization, and clean up, and is repaired convenient for follow-up.It is clear through polishing
After washing processing, parts type of impairment can be divided into surface damage and penetrability damages two classes.
Since laser gain material reparation has heat input energy-controllable and flexibility manufacture characteristic, workpiece stress and change are repaired
Shape is small, is make it especially suitable for the three-dimensional of the precious metals material parts such as titanium alloy, high temperature alloy of large thin-wall structure
It repairs.But parts are damaged for penetrability, such as use laser gain material reparation, it need to be according to part and the design feature in area to be repaired
Adaptability manufacture dedicated substrate is used as the matrix for accepting laser molten pool, just can guarantee that reparation is smoothed out, increases reparation work
The complexity of skill increases non-cutting time and the cost of reparation, reduces remediation efficiency, limits laser gain material renovation technique
The scope of application.
Invention content：
The non-cutting time repaired and cost are reduced the object of the present invention is to provide a kind of, remediation efficiency is improved, first uses essence
Close pulse welding carries out lapping repair to penetrability injuring part, forms the matrix for accepting laser molten pool, then laser is used to increase
The thin-wall part based on pulse welding and laser gain material reparation that the three-dimensional reparation of damaged structure is completed in material reparation is compound
Restorative procedure.
The invention is realized in this way it is characterized in that：
(1) use dyeing inspection method to determine distribution and the trend of the damage of the penetrability such as crackle, and use profile minimum envelop method
Regularization polishing damage field；
(2) use carbide rotary tool to carry out grinding process, form through slot of the shape with respect to regularization；
(3) the optimization polishing of pulse welding groove optimizes polishing to through slot groove, and the angle of groove is controlled at 30 °
Between ~ 60；
(4) the cleaning of through slot and its groove；
(5) the pulse welding lapping repair of through slot；
(6) the polishing and cleaning of bridging REPAIR WELDING body；
(7) the laser gain material reparation of damaged structure：Perforation trench bottom has formed bridging REPAIR WELDING body, and complex structure to be repaired is
Blind slot shape completes the increasing material reparation of entire blind slot, realizes the forming reparation of damaged structure.
The present invention has the following advantages：（1）Pulse welding reparation bridging ability is strong, and substrate is manufactured without otherwise designed, can
Simplify the renovation technique process of penetrability injuring part, improves remediation efficiency；（2）Pulse welding repairs control system output data
Stablize the heat input that can accurately accurately control in repair process, can reduce and repair workpiece deflection, it is high to repair precision；（3）
Laser deposition reparation can realize the three-dimensional reparation of injuring part automatically, improve remediation efficiency and the stability of renovation technique and
Consistency is good；In addition heat input is controllable, and it is small to repair part deformation.
