Description
Technical field
The present invention relates to the method for welding between a kind of metal material, especially a kind of method for welding that welds between different metal materials such as copper or copper alloy and aluminum or aluminum alloy, stainless steel and aluminum or aluminum alloy, stainless steel and the magnesium alloy that is applicable to.
Background technology
In recent years, the copper valency is constantly soaring both at home and abroad, and this has brought very big cost pressure for manufacturings such as refrigeration, electronics, automobile.The main using value of copper is that this material has good conduction, thermal conductivity.Because copper storage capacity in the earth's crust is less, the continuous rise of copper valency is not ccontaining doubtful, therefore seek a kind of performance and copper material near and the relatively low material of price substitute the common starting point that copper material becomes enterprise's saving cost.The conduction and the heat conductivility of aluminum metal are only second to copper, replace the serviceability that copper material can't be crossed the earth effect product in a lot of occasions with aluminium.With regard to production cost, the market price of aluminium is about the l/3 of copper, and the density of aluminium also has only the l/3 of copper, and the aluminum member material cost is 1/9 of an identical copper member.Therefore, people adopt the technology of " with aluminium for copper " to reduce production costs in a lot of industries.
Yet, the use of copper material is still irreplaceable in some members, as the device for drying and filtering in the refrigeration member, capillary, compressor three pipes etc., still will adopt copper pipe to make, in refrigeration pipe, not only aluminum pipe is arranged but also copper pipe is arranged like this, must bring copper aluminum pipe connectivity problem.In addition, because there is the thicker oxide-film of one deck on the aluminium surface, so in some aluminum electronic devices, occur contact heating that causes greatly because of device contacts resistance and the creep failure that causes material easily; Especially also can make the aluminum contact produce discharge spark under the high voltage situation and cause the accident, therefore common way all is at the aluminium material surface soldering copper, reduces contact resistance.
Copper aluminium dissimilar materials interconnection technique there has been more research both at home and abroad, but never very big breakthrough on albronze bonding strength and reduction link cost.The difficult point that copper aluminium dissimilar materials connects is: the fusing point of copper and aluminium differs the thermal conductivity of big (near 400 ℃), copper and is about 3 times of aluminium, their linear expansion coefficient and melting heat very big-difference is also arranged, and direct connection will produce very big welding stress; In addition, more main is that when copper aluminium dissimilar materials connected, the mutual diffusion of atom caused CuAl easily between heterogeneous mother metal
2The formation of compound between the stratiform brittle metal, the thickness of this brittle compound layer will greatly influence the mechanical property of joint when surpassing certain value (10um).Therefore, alleviate the difference of physical property between heterogeneous mother metal as far as possible, and the formation of compound between less stratiform brittle metal, be the key that obtains high-quality copper and aluminium welding joint.
Use more copper aluminium dissimilar materials method of attachment at present and mainly contain friction butt welding, friction stir welding and soldering.The butt welding that wherein rubs is mainly used in the butt joint of pipe or club-shaped material, and friction stir welding is mainly used in the connection of board-like material, these two kinds of methods all belong to the category of Solid-State Welding, equipment is had relatively high expectations, technological parameter is strict, and the production that is not suitable for particular surroundings or complicated joint also is not suitable for the welding of slim member.In addition, Solid-State Welding plumb joint intensity is subjected to CuAl easily
2The thickness of compound layer and hardness influence between brittle metal, joint fatigue durability and air-tightness are relatively poor.
Soldering is used comparatively general in the connection of dissimilar materials, and for example copper aluminium soldering is compared with Solid-State Welding, and the difference of physical property between heterogeneous mother metal has been alleviated in the use of solder in the soldering, and the endurance load-carrying ability of joint is stronger; In addition, it is low that soldering also has a production cost, strong to the adaptability of complex part, strength of joint and air-tightness height, and numerous advantages such as the online production ability is strong, thereby be a kind of very promising copper aluminium interconnection technique.Common method for welding mainly contains vacuum brazing, gas brazing and induction brazing etc.Wherein vacuum brazing is generally carried out under high vacuum environment, and this method has higher requirements to the cleanliness factor of mother metal linkage interface, is not suitable for complicated joint welding and production in enormous quantities.In addition, the vacuum brazing temperature retention time is longer, forms thicker CuAl easily at the copper material interface
2Layer, thus worsened joint performance.Gas brazing and induction brazing all are the modes that adopts local heat, and the heat affected area is little, and weld interval is short, uses comparatively general.Yet these two kinds of method for welding need cooperate brazing flux to use, and to remove the oxide-film of mother metal epidermis, promote the wetting expansion of solder on the mother metal surface.The use of brazing flux has increased the cost of welding on the one hand; In joint, produce pore on the other hand easily; And the brazing flux residue in the postwelding weld seam reduces Joint Reliability if clean out the electrochemical corrosion that also causes joint easily.In addition, gas brazing and induction brazing can not be avoided stratiform CuAl fully
2Generation, have only strict control firing rate and welding temperature could reduce CuAl as far as possible
2The thickness of layer.Same for the soldering between stainless steel and aluminum or aluminum alloy, stainless steel and the magnesium alloy, owing to form compounds affect welding quality between the stratiform brittle metal easily, existing method for welding difficulty has realized the welding of high-efficiency high-quality.
