Description
Technical field
The present invention relates to composite metal plate preparation field, in particular it relates to a kind of copper-steel composite board composition surface defect area
Repair method.
Background technology
Composite metal plate is that two or more sheet metal is brought into close contact to the lamellar composite obtained together
Material.Composite metal plate can make full use of the Wuli-Shili-Renli system approach of composition sheet material each component, so as to improve composite plate entirety
Combination property, simultaneously for the costly metal such as titanium alloy, copper alloy, material is covered using common metal substrate collocation expensive metal
Composite plate structure can substantially reduce the usage amount of expensive metal, production cost be greatly reduced on the premise of performance is ensured.Just
For copper-steel clad metal sheet, due to having both the excellent properties of copper and steel, copper-steel composite plate can be used for manufacture heat exchanger, electricity
Plating electrode, reductor worm gear etc., in fields such as metallurgy, chemical industry, the energy about extensive use.
The preparation of composite plate is crucial, is by certain overlap joint joining technique, realizes being brought into close contact between plate and plate,
Solid and reliable metallurgical binding is produced at composition surface.At present mainly there is commonly used composite plate overlap joint joining technique in industrial production
Explosion composite technology and method hot rolling technology.Explosion composite technology utilizes impulsive force caused by explosive charge so that metallic plate it
Between occur at a high speed that mutually collision combines so as to be formed between firm plate in very short time.The principle of method hot rolling technology is then one
The powerful pressure effect of fixed temperature and milling train is lower to cause metallic plate that plastic deformation and flowing occurs, and promotes the material at composition surface
Diffusion, so as to realize the metallurgical binding of dissimilar metal sheet.Both composite plates overlap joint joining technique can be realized efficiently greatly
The preparation of area composite plate, has all been widely used in actual production.
Because the alloy species of copper alloy, steel are more, sheet material breadth, the configuration of thickness equidimension are various, sometimes composite plate
Lap joint process specification section is narrower and sensitive so that the more difficult control of bond quality of copper-steel composite board, prepares and completes in composite plate
And during heat treatment afterwards etc., often detect that composition surface such as is not bonded at the weld defect in the subregion of copper-steel composite board.
In this case, general the methods of using carbon arc air gouging, is purged to the upper strata metal material at composite plate defect area,
Welding Repair is carried out to defect area using the mode of arc surfacing (SMAW, argon tungsten-arc welding etc.) again.However, due to
There is larger physical property difference in copper, the repairing effect for obtaining fine quality is difficult to using the method for arc surfacing with steel；And
Using the method for arc surfacing, need first by the upper strata metal removal of defect area, then add with upper strata metal similar in wlding enter
Row Bead weld repair, process is more, less efficient, and cost is higher.
Thus, need badly a kind of combination to extensive copper-steel composite board be respectively provided with good overlap joint weldability it is efficient, low into
This repair method.201480043947.9 friction stir welding method, it is considered as difficult welding material when agitating friction welds
Material of the same race or not of the same race in the aluminium alloy casting of material, 2000 systems, 4000 systems, 5000 systems and 7000 line aluminium alloy materials
Two pieces material in can be advantageous to obtain with welding defect intact weld part welding product agitating friction weldering,
But it there are no the repair welding that friction stir welding method is used for copper-steel composite board composition surface defect area.
The content of the invention
It is an object of the invention to provide a kind of repair method of copper-steel composite board composition surface defect area, for extensive
The category combinations of copper-steel alloy, the high quality at the defect area of composition surface, Welding Repair efficiently, inexpensive can be achieved.
To achieve these goals, implementation method of the invention is：For overlapping engagement using certain composite metal plate
Copper-steel composite board that technology is prepared, the composition surface rejected region of copper-steel composite board is entered using stirring friction treatment method
Row repair welding.Copper-steel composite board is anchored on the workbench of friction stir welding machine, is moved to the stirring-head of friction stir welding machine
The top of copper-steel composite board composition surface defect area, stirring-head is set to rotate at a high speed, the mixing needle insertion defect area below stirring-head
The upper metal in domain and through composite plate joint interface, stirring-head then with given pace in defect area straight ahead.
Under the rotation of mixing needle high speed, the metal near copper-steel composite board joint interface is stirred and Plastic Flow occurs, on interface
The dissimilar metal of side and downside realizes mutually fusion through Plastic Flow, so that the defects of being originally present at composition surface (is not pasted
Conjunction, crackle etc.) disappear, form the metallurgical bonding interface of high quality.After the completion of one of stirring friction treatment, lifting stirring-head,
Stirring-head is translated in copper-steel composite board composition surface defect area, continues above-mentioned stirring friction treatment, it is final to cause own
Complete Welding Repair in region.Can subsequently the micro machining such as polish be carried out to composite surface, so that repair welding region surface is put down
It is whole bright and clean.
Alternatively, the overlap joint joining technique of the copper-steel composite board can be one of following approach：Explosion composite technology,
Method hot rolling technology, liquid-solid phase Rolling compund technology, Diffusion Welding technology.
Alternatively, the copper-steel composite board can be combined by two or more single-layer metal plates.
Alternatively, the copper-steel composite board, every layer of metallic plate can be copper coin or steel plate.Copper coin can be fine copper plate, copper
Kirsite plate, signal bronze plate, albronze plate, cupro silicon plate, corronil plate.Steel plate can be any phosphorus content quality
Percentage between 0.02% to 2.11%, iron-carbon alloy added with other elements.
Alternatively, the copper-steel composite board, between 0.1mm-500mm, area exists the thickness of its single-layer metal plate
Between 0.1mm2~20mm2.
Alternatively, the stirring friction treatment, for its mixing needle length between 0.1~200mm, mixing needle can be band spiral shell
The cylinder or cone of spin slot, the diameter of mixing needle bottom is in 0.01~2500mm2Between, stirring-head rotating speed 50~
Between 5000rpm, stirring-head penetrates the depth of copper-steel composite board between 0.1~200mm, push inclination angle 0 °~50 ° it
Between, the straight ahead speed of stirring-head is between 1-2000mm/min.
Alternatively, the stirring friction treatment, in the composition surface rejected region of copper-steel composite board can handle together,
Also multiple tracks processing can be carried out.
Beneficial effect：Compared to arc surfacing method, copper-steel composite board is engaged using above-mentioned stirring friction treatment method
Planar defect region carries out Welding Repair, during need not remove the clad materials of defective locations, need not also add welding material, drop
The low consumption of metal material, reduces production cost；Simultaneously because the reduction and agitating friction technology high mechanization of process
Feature so that production efficiency is higher；Because agitating friction technology is a kind of welding means of very excellent foreign material in itself,
The thus combination for extensive dissimilar metal plate, the Welding Repair of high quality can be all realized using this method.
