Description
The present invention relates to welding technology field, specifically relate to a kind of rare-earth welding material for different metals and manufacture method thereof.
With metal solder not of the same race together, because the difference between the different metal on the performance is very big, so the welding dissimilar metal is usually than welding the many of metal difficulty of the same race, when two kinds of different metals are welded, can run into a lot of difficulties, when differing greatly such as fusion temperature, wherein a kind of metal has been in molten state, and another kind of metal also is in solid-state following; When the coefficient of expansion of two kinds of metals differs greatly, in welding process, can produce very big thermal stress, and this thermal stress can't be eliminated, when the heat conductivility of soldered metal and specific heat have nothing in common with each other, temperature field in the time of can changing welding distributes, thereby change the crystallization condition of weld seam, this is the condition of decision fusing point higher metal wellability feature.Dissimilar metal can obtain satisfied welding point, at first depend on by the physical-chemical performance of weldering metal and employing welding method and technology, during dissimilar metal melting welding, because weld metal and base metals are at chemical analysis, significant difference on tissue and the performance, can cause a series of when metal melting welding of the same race non-existent problem, this all needs to take in when selecting welding method and welding material and definite technological specification.The condition of opposite sex metal melting welding is that mother metal and welding material must all melt and form jointly weld metal, this weld metal is not a boundary line completely, exist the fusion area between them, the fusion area comprises unmixed zone in the weld seam and the incomplete fusion zone in the mother metal, its composition is all different with mother metal and weld seam, and often between both this, in fact form the chemical analysis transition zone, weld metal more is not easy fully to mix with base metals chemical analysis difference, then transition zone is more obvious, and transition zone can suitably be controlled by some technological measure.
Can see from above, welding between the different metal is the comparison difficulty, but the development of modern crafts is more and more many to the requirement that different metal is welded together, all kinds of special industries are all the more so, the requirement that simultaneously traditional steel or iron material can not satisfy modern industry, various metals, including non-ferrous metal and alloy obtains using more and more widely, particularly be the very extensive of aluminium and aluminium alloy application, but aluminium and aluminium alloy and other metal solder difficulty are very big, and aluminium can't weld at present with the metal that has at all.The density of aluminium and aluminium alloy is little, the intensity height, and have good electrical conductivity, thermal conductivity and corrosion resistance, combine the formation member with steel and be of practical significance very much, aluminium can form limit solid solution with the elements such as iron, manganese, chromium and nickel in the steel, also can form intermetallic compound, in different content situations, aluminium and iron can form multiple intermetallic compound respectively, as FeAl, and FeAl

5The most crisp, this intermetallic compound comprises that to the mechanical property of material microhardness all has tangible influence, and aluminium is mutually far short of what is expected with the physical property and the steel of other metal, and this can cause very big difficulty when welding.
Therefore between the weldering between the different metal, mostly be on welding method, to improve, as melting welding, pressure welding, spot welding, ultrasonic bonding, argon arc welding, laser weld etc., some equipment complexity in these welding methods, and some welding must be used welding fluid, this causes complex process, also must clean after the welding, and this also can cause the pollution of environment, welding material to different in nature metal also has some researchs at present, as day disclosure special permission communique, clear 61-154788, in addition as CN001039986 and CN001041556, the technology that these patent documentations provide, can weld some different metal, but welding performance still has many shortcomings.
Goal of the invention of the present invention provides a kind of rare-earth welding material for different metals that can carry out the different metal welding at low temperatures and reaches manufacture method altogether.
Realize that technical solution of the present invention is: the consisting of of rare-earth welding material for different metals: tin is 60-85%, zinc is 10-35%, neodymium is 1-2%, and cadmium is 1-2.5, and copper is 0.25-0.5%, magnesium is 0.05-0.3%, aluminium is 0.11-0.20%, and silver chlorate is 0-3%, and above parameter is a mass percent, the following stated parameter is mass percent, adds the rare metal alloy of 2.0-4.0% more in addition.
