Brazed achikuya musoro

Zvinoenderana nenzvimbo dzakasiyana dzekunyungudika dze solder, brazing inogona kukamurwa kuita yakapfava solder uye yakaoma solder.

Soldering

Soft soldering: nzvimbo yekunyunguduka ye solder ye soft soldering yakaderera pane 450 ° C, uye simba rekubatana rakaderera (pasi pe70 MPa).

Yakapfava solder inonyanya kushandiswa kukwenenzvera kwe conductive, airtight uye isina mvura michina mumaindasitiri emagetsi uye ezvekudya.Tin welding ine tin-lead alloy sesimbi yekuzadza ndiyo inonyanya kushandiswa.Soft solder kazhinji inoda kushandisa flux kubvisa oxide firimu uye kugadzirisa kunyorova kwesolder.Kune akawanda marudzi e soldering fluxes, uye rosin doro mhinduro inowanzo shandiswa kushambadzira muindasitiri yemagetsi.Iyo yakasara yeiyi flux mushure mekushongedza haina corrosive effect pane workpiece, iyo inonzi non-corrosive flux.Iyo inoyerera inoshandiswa pakushongedza mhangura, simbi uye zvimwe zvinhu inoumbwa ne zinc chloride, ammonium chloride uye vaseline.Kana welding aluminium, fluoride uye fluoroborate zvinoshandiswa sebrazing fluxes, uye hydrochloric acid uye zinc chloride zvinoshandiswawo sebrazing fluxes.Izvo zvakasara zveaya mafluxes mushure mewelding anoodza, anonzi corrosive fluxes, uye anofanirwa kucheneswa mushure mewelding.

Brazing

Brazing: nzvimbo yakanyunguduka yesimbi yekuzadza simbi yakakwira kupfuura 450 ° C, uye kusimba kwekubatana kwakakwira (kupfuura 200 MPa).

Brazed majoini ane simba rakawanda, uye mamwe anogona kushanda pakupisa kwakanyanya.Kune akawanda marudzi ebrazing filler simbi, uye aluminium, sirivheri, mhangura, manganese uye nickel-based brazing filler simbi ndiyo inonyanya kushandiswa.Aluminium base filler simbi inowanzo shandiswa kugadzira zvigadzirwa zvealuminium.Silver-based and copper-based solders anowanzo shandiswa kugadzira mhangura nesimbi zvikamu.Manganese-based uye nickel-based solders anonyanya kushandiswa kupinza simbi isina kupisa, simbi inodzivirira kupisa uye zvikamu zve superalloy zvinoshanda pakupisa kwakanyanya.Palladium-yakavakirwa, zirconium-yakavakirwa uye titanium-yakavakirwa masoja anowanzo shandiswa kushambadzira simbi dzinoramba dzakaita seberyllium, titanium, zirconium, graphite uye ceramics.Paunenge uchisarudza simbi yekuzadza, hunhu hwesimbi yepasi uye zvinodikanwa zvekushanda pamwe chete zvinofanirwa kutariswa.Brazing flux inowanzo umbwa nemakloridi uye fluorides yealkali simbi uye inorema simbi, kana borax, boric acid, fluoroborate, nezvimwewo, inogona kugadzirwa kuita hupfu, paste uye mvura.Lithium, boron uye phosphorus inowedzerwawo kune mamwe masoja kuwedzera kugona kwavo kubvisa oxide firimu uye kunyorova.Chenesa iyo yasara inoyerera mushure mekupisa nemvura inodziya, citric acid kana oxalic acid.

Ongorora: Iyo yekusangana pamusoro pesimbi yepasi inofanira kuve yakachena, saka iyo flux inofanirwa kushandiswa.Basa rebrazing flux nderokubvisa okisidhi uye kusvibiswa kwemafuta pamusoro pesimbi yepasi uye yekuzadza simbi, chengetedza nzvimbo yekubatana pakati pesimbi yekuzadza uye base simbi kubva kune oxidation, uye kuwedzera kunyorova uye capillary fluidity yesimbi yekuzadza.Iko kunyunguduka kwekuyerera kuchave kwakadzikira pane iyo solder, uye kukora kweiyo inoyerera yakasara panheyo simbi uye kubatana kuchave kushoma.Iyo inowanzoshandiswa flux yekunyorovesa solder is rosin kana zinc chloride solution, uye iyo inowanzo shandiswa flux yebrazing musanganiswa weborax, boric acid uye alkaline fluoride.

Kushandisa uye chimiro kugadzirisa uye kutepfenyura

Brazing haina kukodzera kusungirirwa kwezvimiro zvesimbi zvakajairwa uye zvikamu zvinorema uye zvine simba.Inonyanya kushandiswa pakugadzira zviridzwa zvakarurama, zvigadzirwa zvemagetsi, zvakasiyana-siyana zvesimbi zvikamu uye zvakaoma zvidhinha zvimedu zveplateti, zvakadai sezvikamu zvesangweji, zvivakwa zvehuchi, nezvimwewo. Inowanzoshandiswawo kugadzira tambo dzakasiyana-siyana dzakasiyana-siyana uye cemented carbide tools.Munguva yebrazing, mushure mekusangana kwechiso chebrazed workpiece yacheneswa, inounganidzwa muchimiro chekupindirana, uye simbi yekuzadza inoiswa padhuze negeji rekubatana kana zvakananga mugomba rekubatana.Kana iyo workpiece uye solder zvinopisa kune tembiricha yakakwira zvishoma pane kunyunguduka kweiyo solder, iyo solder inonyungudika uye inonyorovesa pamusoro peiyo weldment.Iyo yemvura inozadza simbi inoyerera uye ichipararira pamwe nemusono nerubatsiro rwe capillary chiito.Naizvozvo, iyo brazed simbi uye filler simbi inonyungudika uye inopinzwa mukati meumwe neumwe kuita alloy layer.Mushure mekunyunguduka, iyo brazed joint inoumbwa.

Brazing yakashandiswa zvakanyanya mumakanika, magetsi, zviridzwa, redhiyo uye mamwe madhipatimendi.Carbide zvishandiso, zvimedu zvekuchera, mafuremu emabhasikoro, zvinopisa kupisa, makonditi uye midziyo yakasiyana-siyana;Mukugadzira microwave waveguides, emagetsi machubhu uye emagetsi vacuum zvishandiso, brazing ndiyo chete nzira inogoneka yekubatanidza.

Zvinoumba brazing:

Brazed diamond inokuya vhiri

Brazed diamond inokuya vhiri

(1) Iyo yekudziya yekupisa tembiricha yakadzikira, iyo joint yacho yakatsetseka uye yakati sandara, shanduko ye microstructure uye michina zvimiro idiki, deformation idiki, uye saizi yebasa ndeyechokwadi.

(2) Inogona weld dissimilar simbi uye zvinhu pasina zvirambidzo zvakasimba pamusoro ukobvu musiyano weworkpiece.

(3) Dzimwe nzira dzekubhuroka dzinogona weld mawelds akawanda uye majoini panguva imwe chete, nekubudirira kwakanyanya.

(4) Brazing midziyo iri nyore uye kugadzirwa kwekudyara kwakaderera.

(5) Kusimba kwemajoini kwakadzikira, kusadzivirirwa nekupisa kwakashata, uye zvinodiwa pakuchenesa musati mavenda zvakasimba, uye mutengo wesolder unodhura.
