Technical field
The present invention relates to Welding Structure and the welding method thereof of a kind of Nitinol and different metal materials, especially Nitinol and stainless Welding Structure and welding method thereof.
Background technology
The surgical instruments of Head and neck tumour adopts stainless steel, cochrome, superelastic NiTi alloy or macromolecular material to make usually, wherein particularly niti-shaped memorial alloy is expensive for Nitinol, itself and stainless steel or other cheap materials are carried out welding and forms composite construction, then can reduce costs while utilizing the memory effect of niti-shaped memorial alloy, super-elasticity, corrosion resistance.And at present, conventional welding manner is for directly welding after Nitinol and stainless steel docking or overlap joint, frangible compounds in weld seam and welding point internal stress very easily cause weld seam to crack, and can cause weld failure, have impact on the service life of this composite construction.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide one and Nitinol can be made effectively to weld with different metal materials, ensure that the Nitinol in sandwich service life and the Welding Structure of different metal materials and welding method thereof.
The object of the present invention is achieved like this:
The Welding Structure of a kind of Nitinol and different metal materials, it comprises Nitinol part and metal parts, described Nitinol part and metal parts are strip, wherein metal parts and Nitinol part are inhomogeneous metal material, the front end of described Nitinol part offers at least two through holes, described through hole is stairstepping, the bottom bore of this stairstepping through hole is less than top bore, the end of described metal parts is provided with in the equal lug boss of number of openings, described lug boss upwards inserts from the bottom of stairstepping through hole, thus the front end of Nitinol part installs on the end of metal parts, metal ring is plugged with between the top of lug boss and stairstepping through hole, this metal ring is identical with the material of metal parts, the front end of described Nitinol part and the end laser weld of metal parts, and lug boss, metal ring and through hole also pass through laser weld, thus by Nitinol part and metal parts welded together.
Described metal parts is stainless steel parts, and metal ring is stainless steel annulus.
First on Nitinol part, process multiple stairstepping through hole, and on stainless steel parts, process multiple lug boss corresponding with stairstepping through hole, before welding, the front end of Nitinol part is installed on stainless steel parts end, lug boss upwards inserts from the bottom of stairstepping through hole, in stairstepping through hole, fill in stainless steel annulus subsequently entangle to the lug boss of stainless steel parts, then by the front end of Nitinol part and stainless steel parts end laser weld, lug boss simultaneously along stainless steel parts welds, the stainless steel metal solution melted in welding process is filled in the space between Nitinol and stainless steel, simultaneously by stainless steel annulus, lug boss and the Nitinol of stainless steel parts are welded together.
Welding Structure and the welding method thereof of Nitinol of the present invention and different metal materials have the following advantages:
The Welding Structure of a kind of Nitinol and different metal materials and welding method thereof, it passes through the front end of Nitinol part and stainless steel parts end laser weld, lug boss simultaneously along stainless steel parts welds, the stainless steel metal solution melted in welding process is filled in the space between Nitinol and stainless steel, simultaneously by stainless steel annulus, lug boss and the Nitinol of stainless steel parts are welded together, even if the weld failure like this between Nitinol and dissimilar metal, Nitinol part and metal parts also can firmly fix by the metal ring had more, thus Nitinol is effectively welded with different metal materials, ensure that sandwich service life.
