Connect.The bonding joint mechanical strength obtained is the highest, can be used only in the occasion that some butt joint performance requirements are the highest；Though being mechanically connected
So it is still and realizes the important method that aluminium alloy is connected with steel, but, the component obtained by such mechanical connection means is airtight
Property poor, and joint is heavier, and shape is also restrained, has no idea to meet high-quality Al and aluminium alloy and steel is combined
Structural member demand in auto manufacturing, particularly higher to some surface requirements workpiece such as automobile panel, it is difficult to full
Foot requirement；Welding as method of attachment important in metal material, status and advantage in industry manufacture are that other connects
The method of connecing can not be substituted, and for automobile industry, and remaining on is the mode of a kind of economical rationality.
Dissimilar metal is because of the difference of character, and welding is relatively difficult.Particularly the welding between steel and aluminum, always is
A difficult problem for the research of welding field.Welding method almost relates to the various methods that welding field is conventional at present, such as agitating friction
Weldering, arc welding, Laser Welding, electric arc laserHybrid welding etc..Welding pretreatment technique includes sealing weld silk, fills out metal dust, interpolation
Pad is as barrier layer, plating Zn or Al as transition zone etc., and these pre-treating technologies are all to its property of welded joint
Improve, and intensity still cannot meet the demand of practical application in industry.Under this overall background of automotive light weight technology, high-strength steel, super
The application of the light metals such as high-strength steel and the high aluminium alloy of specific strength, magnesium alloy is more and more extensive, high strength steel and aluminium alloy it
Between weldability problems demand solve.
Summary of the invention
For solving the problem that existing prior art exists, the present invention provides the welding procedure of a kind of high-strength steel and aluminium alloy,

Degree is set as 725 DEG C, and the time of aluminising is 80～100 s；
(4) cool down, polish: the high-strength steel natural cooling after hot aluminizing, after cooling, use sand papering；
(5) welding: use alternating current TIG welding method to weld high-strength steel and aluminium alloy, uses the TIG weld ginseng optimized
Number: welding current 78 ~ 82 A, speed of welding 0.6 ~ 0.8 m/min.
Between described step (2) and (3), need high-strength steel is air-dried after step (2), and carry out step immediately
(3).
Aqueous solution type activator in described step (2) is by AlCl3And AlF3Composition, its proportioning is 1:1.
The constituent of the aluminising liquid in described step (3) includes aluminum 88.5%, copper 5%, nickel 3%, manganese 0.6%, alterant
2.15%, refining agent 0.75%.
Beneficial effects of the present invention:
In the present invention, the activation processing before hot aluminising can activate surface of steel plate, and forms layer protecting film at surface of steel plate, is oozing
Make aluminum liquid extend at steel surface during aluminum, make steel surface by the good moistening of liquid aluminium liquid, thus to promote to obtain high-quality
Alumetized steel, the microcosmic injustice activating surface of steel plate in addition can play certain " nail catcher " effect, promote between aluminized coating and matrix
Combination.
The present invention welds after high strength steel surface active hot-dip aluminizing again, is formed between leaching aluminium lamination and steel matrix
One layer of thin intermetallic compounds layer, it can play certain barrier action in welding process.Additionally, the leaching of high strength steel surface
Aluminum, it is also possible to avoid or reduce its oxidation in the course of processing, also can play a protective role during depositing.
Present invention optimizes the solder technology of high strength steel and aluminium alloy, the research for automotive light weight technology provides basis, for
The application on automobile of high strength steel and aluminium alloy integral structure provides bigger development space and breakthrough.
