Soldering yog txheej txheem soldering uas heats li thiab melts tin solder, uas feem ntau ua hauj lwm raws li ib tug nto kev twb kev txuas ntawm qhov chaw uas soldered. Nws melting point yog 232 degree. Stainless hlau, ntawm qhov tod tes, muaj qhov melting point ntau dua, feem ntau siab dua 1400 degree. Qhov no txhais tau hais tias thaum kub siab, yuav muaj qhov sib txawv ntawm qhov kub thiab txias ntawm tin thiab stainless hlau. Qhov no yog vim li cas feem ntau hom stainless hlau nyob rau hauv kev ua lag luam tsis tuaj yeem soldered, laser soldering tsis tuaj yeem welded. Qhov no yog vim muaj qhov sib txawv loj ntawm cov khoom, kev txwv melting thiab lub zog ntawm cov khoom siv hauv paus thiab cov khoom siv solder.
Stainless hlau yog cov hlau uas nws cov khoom tseem ceeb suav nrog hlau, chromium, npib tsib xee thiab manganese. Nyob rau saum npoo ntawm stainless hlau, feem ntau yog nyias txheej ntawm chromium oxide, uas tsuas yog ob peb nanometers tuab. Cov txheej txheem oxide no yog txheej tiv thaiv tseem ceeb ntawm cov hlau tsis muaj steel, uas tuaj yeem tiv thaiv qhov chaw ntawm stainless hlau los ntawm oxidative corrosion. Nyob rau tib lub sijhawm, chromium oxide txheej yog qhov nyuaj heev thiab tiv thaiv cov khoom siv sab nraud los ntawm kev ua tshuaj lom neeg nrog cov hlau tsis huv. Tsis tas li ntawd, muaj qhov sib txawv ntawm cov khoom siv tshuaj lom neeg ntawm tin thiab stainless hlau. Tin yog ib qho acidic tshuaj, nyob rau hauv kev sib cuag nrog acid, acidic tshuaj yuav tsim ib tug tshuaj tiv thaiv. Stainless hlau, ntawm qhov tod tes, muaj cov kua qaub zoo dua, thiab txawm tias nws los rau hauv kev sib cuag nrog cov kua qaub, tsis muaj tshuaj tiv thaiv tseem ceeb yuav tshwm sim.
Yog li ntawd, lub hauv paus ntsiab lus ntawm stainless hlau tsis stain lub tin lies nyob rau hauv lub stainless hlau nto ntawm txheej tiv thaiv tau zoo tiv thaiv lub nto ntawm stainless hlau tsis oxidized corrosion thiab tiv thaiv lwm yam tshuaj thiab stainless hlau tshuaj tiv thaiv, thiab tin thiab stainless hlau lub cev. thiab cov khoom siv tshuaj lom neeg ntawm qhov sib txawv ntawm ob yuav ua rau muaj kev adhesion ntau dua ntawm ob qhov tsis txaus ua rau tsis yog-stick, thiab cov no kuj yog qhov tseeb feem ntau ntawm cov hlau tsis muaj steel tsis tuaj yeem tin soldering ntawm lub ntsiab yog vim li cas.
Yuav ua li cas stainless hlau yuav soldered?
1, tin soldering tuaj yeem welded ntau yam, tsuas yog ib feem ntawm cov hlau muaj qhov zoo solderability, tuaj yeem txuas nrog tin soldering. General tooj liab thiab nws cov alloys, kub, nyiaj, zinc, npib tsib xee, thiab lwm yam nrog zoo weldability, thiab txhuas, stainless hlau, cam khwb cia hlau, thiab lwm yam Weldability yog heev tsis zoo, feem ntau yuav tsum tau siv tshwj xeeb fluxes thiab txoj kev rau solder.
2, welding stainless hlau, tin solder yuav tsum tau nruj dua. Tin solder muaj pes tsawg leeg los yog impurities tshaj tus qauv yuav cuam tshuam qhov zoo ntawm solder, tshwj xeeb tshaj yog ib co ntawm impurity cov ntsiab lus, xws li zinc, txhuas, cadmium, thiab lwm yam, txawm tias nws yog 0.001% ntawm cov ntsiab lus yuav ho cuam tshuam cov wettability thiab fluidity, txo qhov zoo ntawm vuam.
3, rau stainless hlau vuam feem ntau yuav tsum tau siv tshwj xeeb flux thiab txoj kev rau solder.
Stainless hlau soldering tsuas tuaj yeem ua si qee qhov kev sib khi thiab lwm yam kev tiv thaiv, thiab tsis tuaj yeem ua tiav cov khoom siv vuam, stainless hlau vuam lossis yuav tsum siv laser vuam, thiab laser soldering txawv, stainless hlau laser vuam yog siv cov kab teeb ci laser ntawm lub tshuab. workpiece rau cov cua sov hauv zos mus rau qhov kub thiab txias, kom cov hlau nto vaporization thiab evaporation ntawm kev tsim ntawm metallurgical bonding txheej ntawm ib txoj kev sib txuas, qhov kub tuaj yeem ncav cuag ntau tshaj 1400 degree. Nws yog tus cwj pwm los ntawm: tsis sib cuag cua sov, tsis muaj thermal deformation; tswj kub thiab sijhawm, txhim kho cov khoom zoo; txo cov nqi tsim khoom; muaj feem xyuam rau cov khoom sib txawv (xws li carbon steel, alloy steel, thiab lwm yam) ntawm qhov chaw ntawm kev sib txuas lossis kho thiab lwm yam. Zichen stainless hlau laser vuam tshuab yog dav siv nyob rau hauv kev lag luam automotive, aerospace teb thiab txhua yam khoom kho thiab lwm yam teb.
1, vim yog cov yam ntxwv ntawm cov hlau tsis muaj hlau yog thermal conductivity, thermal fusion, coefficient ntawm linear expansion yog loj heev, yog li cov vuam muaj teeb meem ntau dua, koj yuav tsum siv cov txheej txheem vuam tsim nyog los xyuas kom zoo.
2, kev tsim kho vuam yuav tshwm sim thaum cov seem seem tawg, yog li peb yuav tsum ua txoj haujlwm zoo ntawm kev tiv thaiv kev tiv thaiv, xws li hnav lub qhov muag tiv thaiv thiab kaus mom hlau, uas tuaj yeem ua kom peb tus kheej muaj kev nyab xeeb.
3, vuam lub sij hawm rau spatter rau nrog, cov khoom no yog heev yooj yim mus ua raws li cov txheej txheem ntawm stainless hlau, uas yuav ua rau siv lub sij hawm ntawm stainless hlau hloov, luv welding ua ntej yuav tsum tau mus thov anti-spatter tus neeg saib xyuas ntawm lub vuam chaw nres nkoj.
4, vuam, yog tias qhov kev ua haujlwm tsis tsim nyog yog qhov yooj yim heev kom tshem tawm qhov tsis xws luag hauv txheej txheej, xws li kev puas tsuaj rau cov yeeb yaj kiab tiv thaiv, yog li vuam yuav tsum nyob rau hauv qhov vuam channel arc, cov kab hauv qhov sib txawv.
Saum toj no yog qee cov ntaub ntawv hais txog stainless hlau welding, los ntawm cov saum toj no peb tuaj yeem pom tias laser tin vuam tsis tuaj yeem vuam stainless hlau, txawm hais tias qee cov qauv tshwj xeeb ntawm cov ntawv stainless hlau tuaj yeem ua tau, tab sis tsuas yog nyob rau hauv stainless hlau sealing tiv thaiv. Yuav tsum xaiv lub tshuab vuam tuaj yeem ua tiav kom yaj cov hlau qhov chaw, xaiv stainless hlau tsis siv neeg laser vuam tshuab, koj tuaj yeem txo qhov kev ua haujlwm tsis zoo ntawm kev ua haujlwm los ntawm kev poob, kom tsis txhob muaj teeb meem ntawm kev nrhiav neeg ua haujlwm nyuaj.
