Abstract
The invention discloses a kind of bolt assembly laser welding processing methods; in this method bolt assembly by bolt and spring plate group at; bolt and spring sheet material are GH4169 high temperature alloy; spring leaf is assemblied in bolt head; at laser welding assembly connection; laser welding waveform is using double triangular waves; using inert gas shielding; vacuum drying is carried out to bolt assembly before laser welding; vacuum destressing is carried out to bolt assembly after laser welding, it is ensured that the defects of bolt assembly weld seam carries out X-ray examination flawless and bubble by HB/Z60.The method of the present invention successfully solves GH4169 bolt assembly, and using weld seam after conventional triangular laser waveform progress laser welding, by HB/Z60 progress X-ray examination, there are crackles, the processing technology bottleneck of bubble, can be applied on aviation bolt assembly laser welding manufacture field.
Description
Technical field
The present invention relates to a kind of bolt assembly laser welding processing methods, belong to high temperature alloy welding technology field.
Background technique
GH4169 bolt assembly is by bolt and spring plate group at bolt needs to add using laser welding after assembling with spring leaf
Work, last bolt assembly will be installed on engine high pressure rotor, bear certain torsion important part, the use to engine
Service life plays key effect.The weld seam of the bolt assembly by HB/Z60 carry out X-ray examination there are crackle or bubbles the problems such as, one
Directly fail effectively to be solved.
Summary of the invention
The purpose of the present invention is to provide a kind of bolt assembly laser welding processing method, this method, which can effectively solve the problem that, is adopted
There are crackle, bubbles etc. by HB/Z60 progress X-ray examination for weld seam after carrying out laser welding with conventional triangular laser waveform
Problem.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of bolt assembly laser welding processing
Method, the bolt assembly by bolt and spring plate group at, when bolt and spring leaf are welded together, first to bolt with
Spring leaf carries out drying and processing, then bolt and spring leaf is welded and fixed using laser welding mode, the waveform of laser welding
For double triangular waves, the power of double triangular waves, frequency, end decaying, speed of welding, tolerance, takes an interval, Beam rotation at the time
The parameters such as angle, defocusing can be reasonably selected according to the structure size of bolt and spring leaf；It is protected when welding using inert gas
Shield carries out destressing processing to bolt assembly after swashing laser welding.
In the above method, the bolt and spring sheet material are GH4169 high temperature alloy, and spring leaf is assemblied in bolt head
Portion.
In the above method, the inert gas use purity for 99.999% argon gas.
In the above method, vacuum drying is used before laser welding, drying temperature is no more than 400 DEG C；It is used after laser welding
Vacuum destressing, destressing temperature are no more than 600 DEG C.
Detailed description of the invention
Fig. 1 is the installation diagram of GH4169 bolt assembly；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the waveform diagram for double triangular waves that laser welding processing uses in the present invention.
Compared with prior art, the beneficial effects obtained by the present invention are as follows being: laser welding waveform of the invention is using double three
Angle wave uses vacuum drying before welding, and when welding uses inert gas shielding, to effectively solve to swash using conventional triangular wave
Waveform carry out laser welding after weld seam by HB/Z60 carry out X-ray examination there are crackles, bubble the problems such as.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and examples to this hair
It is bright to be described in further detail.
The embodiment of the present invention: being illustrated in the present embodiment using GH4169 bolt assembly, GH4169 bolt assembly
Structural schematic diagram it is as shown in Figures 1 and 2.A kind of bolt assembly laser welding processing method of the invention, bolt assembly is by spiral shell
Bolt 1 and spring leaf 2 form, and referring to Fig. 3, for laser welding waveform using double triangular waves, when welding uses inert gas shielding, bolt
1 and 3 material of spring leaf are GH4169 high temperature alloy, and spring leaf 2 is assemblied in the head of bolt 1, and the weld seam 3 of laser welding is filling
With junction.The power of double triangular waves of laser welding, the time, frequency, end decaying, speed of welding, tolerance, take an interval,
The parameters such as Beam rotation angle, defocusing such as table 1, inert gas use purity for 99.999% argon gas.Using true before laser welding
Sky drying, keeps the temperature 4h by 400 DEG C of drying temperature；Vacuum destressing is used after laser welding, 600 DEG C of destressing temperature, keeps the temperature 4h；
Vacuum degree control is in (2~8) × 104Pa.It can guarantee that bolt assembly weld seam carries out X-ray examination flawless and bubble by HB/Z60
The defects of.
