The invention discloses a kind of 6005A ultra-thin aluminum alloys plate friction stir welding method, by increasing stirring-head rotating speed, reduce stirring-head welding pressure, so as to solve the problems, such as the overlap joint of long weld seam ultra thin plate, not only make section bar lap weld specious, dimensional accuracy is high, section bar postwelding size and mechanical property is met technical requirements, welding efficiency is substantially increased, production cost is reduced.
Description
Technical field
The invention belongs to welding field, and in particular to a kind of 6005A ultra-thin aluminum alloys plate friction stir welding method.
Background technology
The material that bus bottom plate is used be 6005A aluminium alloys, its wall thickness 1.85mm, dimensional accuracy superelevation essence level, after
The requirement of phase processing characteristics exceedes Standard, and specific performance is：Rp0.2 (MPa) >=240, Rm (MPa) >=260, A (%) >=7,
And existing welding technique is difficult to meet ultra-thin board size and performance requirement.It is attached by agitating friction weldering, its weld seam power
Performance is learned up to the 95% of mother metal performance, but for aluminium alloy public transport vehicle body, is welded using Friction stir welding
Section bar wall thickness be all higher than 2mm, therefore, it is necessary to propose it is a kind of suitable for wall thickness below 2mm friction stir welding method,
To meet ultra-thin board size and performance requirement.
The content of the invention
In view of this, it is an object of the invention to provide a kind of 6005A ultra-thin aluminum alloys plate friction stir welding method, make
Section bar postwelding size and mechanical property meet technical requirements, and are obviously improved welding efficiency.
To reach above-mentioned purpose, the present invention provides following technical scheme：A kind of 6005A ultra-thin aluminum alloys plate agitating friction weldering
Method is connect, friction stir welding machine is selected, the technological parameter of agitating friction weldering is controlled；Wherein, stirring-head underthrust speed 12mm/min,
The control of stirring-head rotating speed is in 1000r/min in down process, and mixing needle underthrust depth 1.85mm, stirring-head welding pressure is set to
The control of stirring-head rotating speed is in 1400r/min in 4.7KN, welding process, and speed of welding is 1020mm/min.
Further, the friction stir welding machine uses the full-automatic friction stir welding machines of ESAB.
The beneficial effects of the present invention are：By improving and controlling the technological parameter of agitating friction weldering, increase stirring-head turns
Speed, reduces stirring-head welding pressure, so as to solve the problems, such as the overlap joint of long weld seam ultra thin plate, not only makes section bar lap weld appearance
Attractive in appearance, dimensional accuracy is high, section bar postwelding size and mechanical property is met technical requirements, substantially increases welding efficiency,
Reduce production cost.Experiment proves that, weld strength can reach the 95% of strength of parent, and weldment is just rolled over, reflexed is satisfied by state
Mark is required, and reflexed angle is bigger.
Embodiment
The preferred embodiments of the present invention will be described in detail below.
In the present embodiment, using the full-automatic friction stir welding machines of ESAB to 6005A ultra-thin aluminum alloy plate welds, welding process
The technological parameter of middle control agitating friction weldering；Wherein, stirring-head rotating speed control in stirring-head underthrust speed 12mm/min, down process
System is in 1000r/min, and mixing needle underthrust depth 1.85mm, stirring-head welding pressure is set to stirring-head in 4.7KN, welding process
Rotating speed is controlled in 1400r/min, and speed of welding is 1020mm/min.
For the long weld seam of thin plate, welding process is easily collapsed, weldering leakage, the low problem of Weld Performance, by existing
Friction stir welding is improved, and increases stirring-head speed, reduces stirring-head pressure, and the overlap joint for solving long weld seam ultra thin plate is asked
Topic, not only makes section bar lap weld specious, and dimensional accuracy is high, section bar postwelding size and mechanical property is met technology
It is required that, welding efficiency is substantially increased, production cost is reduced.Experiment proves that, weld strength can reach strength of parent
95%, weldment is just rolled over, reflexed is satisfied by Standard, and reflexed angle is bigger.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
