Abstract
A kind of agitating friction method for welding, the narrower joint face of first connector is welded on the wider joint face of the second connector, the solder film of preset low melting point between the joint face of the first connector and the second connector, then the narrower joint face of the first connector is welded on the wider joint face of the second connector by agitating friction weldering.
Description
Technical field
The application is related to aircraft manufacturing technology, the more particularly to corrosion-resistant welding of airplane component, is specifically that a kind of stirring rubs
Wipe method for welding.
Background technology
In aircraft manufacturing field, in order to reduce the impost that connector is brought, while reach the mesh for reducing manufacturing cost
, advanced Aluminum Alloy Friction Stir Welding technology is widely used, to reduce or abandon traditional riveting and screw-jointing method.
Agitating friction weldering due in welding process material it is non-fusible, it is possible to achieve it is all kinds of of the same race or xenogenesis high-strength/tenacity aluminum alloy reliable
Connection, the entirety manufacture especially suitable for aircraft skin-stringer structure.A large amount of airplane components have selected high strength weldable aluminium to close
Gold, material thickness are concentrated mainly between 1.0~2.0mm, and joint form is L-type and T-shaped, using agitating friction weldering Welder
Skill.But agitating friction weldering has the defects of unconquerable, due to the peculiar structure of friction stir welding, shape between connector
Into gap be easily detained steam, cause serious corrosion, reduce Aircraft life, be not suitable for marine climate.For long-term place
Aircraft under Yu Haiyang environment, by the erosion especially severe of high temperature, high humidity and high salt, therefore it is required that in manufacturing process, connector
Weld seam possess extremely strong corrosion resistance characteristic, welding bead both sides must not be detained steam.
The content of the invention
It is an object of the invention to the perishable shortcoming that can not be overcome for agitating friction welding, a kind of agitating friction is proposed
Method for welding.
A kind of agitating friction method for welding, the narrower joint face of the first connector is welded to the wider company of the second connector
In junction, it is characterised in that the solder film of preset low melting point between the joint face of the first connector and the second connector, then lead to
Cross agitating friction weldering the narrower joint face of the first connector is welded on the wider joint face of the second connector.
The beneficial effect of the application is：1) solder film is put between connector, by agitating friction weldering, in forging force
Under heating synergy, solder film melts and solidified again, the gap being filled between connector, is formed, and blocks steam to enter
Enter brazed seam；2) present invention is simple and easy, can effectively improve the corrosion phenomenon of airplane parts.3) the application forms a kind of stirring and rubbed
Brazed assembly is wiped, the component can effectively prevent the corrosion of weld seam.
Accompanying drawing is described in further detail to the application with reference to embodiments：
Brief description of the drawings
Fig. 1 is the gap schematic diagram that agitating friction is welded in the formation of weld seam both sides.
Fig. 2 is the agitating friction method for welding schematic diagram of the application.
Fig. 3 is in the second connector preseting solder film schematic diagram.
Fig. 4 is welding front connector combination diagram.
Fig. 5 is the sealing fillet schematic diagram that the agitating friction soldering of the application is formed in weld seam both sides.
Explanation is numbered in figure：It is 1 first connector, 2 second connectors, 3 weld seams, 4 gaps, 5 solder films, 6 stirring-heads, 7 close
Seal brazed seam
Embodiment
Referring to accompanying drawing, the narrower joint face of the first connector 1 is welded to using traditional agitating friction welding technique
On the wider joint face of two connectors 2, two interspaces 4 are inherently left at the left and right sides of weld seam 3, gap size exists
0.2mm~0.6mm, and it is wedge shaped, and outer imperial palace is small.It is overall again in not specification state because gap is smaller, it is external to be easy to absorption
Material, and closed wherein, and be not easy to exclude.For example the covering of aircraft is connected with stringer using agitating friction weldering,
When being run under marine environment, wherein the gap of covering-stringer can absorb, be detained corrosive salt fog, steam or other materials,
And be not easy to exclude, meeting heavy corrosion component in the short time, cause aircraft deactivation or overhaul, or even change partial component.
The agitating friction method for welding and agitating friction brazed assembly that the application proposes, connect in the first connector 1 and second
The solder film 5 of preset low melting point between the joint face of fitting 2, then by the stirring-head 6 of agitating friction weldering by the first connector 1
Narrower joint face is welded on the wider joint face of the second connector 2.By agitating friction weldering, stirring-head 6 forging force and
Heat under synergy, solder film 5 melts and solidified again, the gap 4 being filled between connector, forms and blocks steam to enter
The sealing brazed seam 7 entered；
In implementation, described solder film is film-form tin-lead solder film.Mixed by H1SnPb39 or 90Sn-10Zn+ agent 402
Make.Described solder film 5 is placed on the region to be welded of the wider joint face of the second connector 2, the overall width of solder film 5 and
The narrower joint face width matching of a connection piece 1.
In order to avoid influence of the solder film to stir friction welding seam 3, in implementation, solder film 5 preferably avoids the position of weld seam 3
Put, that is, solder film 3 is made up of left and right two solder films, is staying for corresponding weld seam between left solder film and right solder film
White space, it is no solder film being left white space, the first connector 1 and the second connector 2 are left white space and are at this during welding
Directly contact.
