For 7020 aluminium alloy extrusions, compare the performance ginseng that aluminum profile joinery and its construction is connected chemically and commonly welds
Number, as shown in table 1, the performance parameter of 7020 aluminium alloy base materials and welding point material estimate contrast table.
The performance parameter of 1 7020 aluminium alloy base material of table and welding point material estimates contrast table
| Parameter | Aluminium alloy | Welded joints in aluminium alloy | Welding reduces ratio |
| Tensile strength | 393 | 268 | 31.8% |
| Elongation | 16.6 | 4.5 | 72.9% |
Test example 1
Apply bending, twisting conditions respectively to embodiment 1 and apply Subjected To Combined Axial Loading And Bending operating condition and crankling vibration operating condition, will weld
Connector is applied to butt welding example and compares correlation performance parameters, comparing result data are it is found that after aluminum alloy piping welding as shown in table 2
The performance of its structure will be greatly reduced.
2 7020 aluminium alloy extrusions of table, which is connected chemically, estimates contrast table with the performance parameter of butt welding welding
| Parameter | Joinery and its construction is connected chemically | Ordinary construction welding |
| Bending stiffness (N/mm) | 777.7 | 748.35 |

Test example 2
Subjected To Combined Axial Loading And Bending operating condition and crankling vibration operating condition, as shown in table 3, comparison combination operating condition are applied respectively to implementation column 2
Deform index.By date comprision, welding point is applied to L-type weld example, its structure after aluminum alloy piping welding
Performance has obvious reduction.
3 7020 aluminium alloy extrusions of table, which is connected chemically, estimates contrast table with the performance parameter of L-type welding
| Parameter | Joinery and its construction is connected chemically | Ordinary construction welding |
| Subjected To Combined Axial Loading And Bending operating condition maximum displacement (mm) | 1.293 | 1.637 |
| Crankling vibration operating condition maximum displacement (mm) | 0.014 | 0.018 |
Under loading, the displacement that composite condition is deformed is bigger, then rigidity is smaller, respectively from Subjected To Combined Axial Loading And Bending operating condition and
Crankling vibration operating condition considers that the deformation displacement of ordinary couplings is bigger than the connector displacement of chemical bonds, therefore reduced performance after welding.
In conclusion welding point can reduce the deformation rigidity of profile entirety, it is unfavorable for the bearing capacity of body frame.Aluminium
Alloy thermal conductivity is higher, and linear expansion coefficient is big, easily there is the defects of deformation, crackle, stomata in the welding process；Due to connecing
Head performance decline is larger, is easily broken tough, corrosion and fatigue in commissure in practical applications and destroys.It is common to weld under limiting condition
Connector is easier to fail.
Single connector has obvious reduction to the performance of structure, it is contemplated that car body of aluminum alloy skeleton has more weldering
Connector, the up to several hundred place's interactions in welding position, the influence to vehicle performance are bigger.
Aluminium alloy extrusions joinery and its construction has used for reference the connection of ancient times solid wood, and aluminium alloy extrusions joinery and its construction compares conventional aluminium
Alloy connection receiving load is stronger, is formed by frame structure allows certain deformation, and energy-absorbing effect is good；In order to improve tenon
The validity of fourth of the twelve Earthly Branches connection, uses joinery and its construction and is connected chemically, this, which is connected chemically to be analogous to, is integrally machined molding, solderless
Connector is not in the damage of welding point position.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
