Vuam yog txheej txheem uas siv cov cua sov thiab melted muab tub lim (solder) los koom ua ob lossis ntau qhov haujlwm ua ke. Hauv kev lag luam hluav taws xob thiab hluav taws xob, vuam yog tsuas yog siv los ua kom muaj kev sib txuas hluav taws xob ruaj khov thiab kho tshuab. Nws cov khoom siv tseem ceeb suav nrog cov hlau nplaum, qhov chaw nres tsheb, cov xaim hlau, cov dej ntws, thiab cov cuab yeej tu. Lub soldering hlau hloov cov cua sov mus rau lub solder sib koom los ntawm nws cov rhuab hlau taub hau, melting lub solder thiab wetting qhov chaw tau koom. Tom qab txias, ib qho kev sib koom ua ke muaj zog yog tsim.
Rau cov khoom siv hluav taws xob xws li siab -voltage switches thiab relays, "Brazing Silver to Copper" yog ib qho tseem ceeb ntawm kev xav tau. Silver muaj cov khoom siv hluav taws xob zoo heev, thaum tooj liab muaj hluav taws xob thiab thermal conductivity. Kev sib koom ua ke ntawm ob los ntawm kev sib txuas los yog kev siv vuam tuaj yeem tsim tau siab -cov khoom siv hluav taws xob tiv tauj. Kev xaiv cov khoom siv vuam yog nyob ntawm qhov loj me, batch loj, thiab cov kev xav tau zoo: phau ntawv soldering irons yog tsim rau me me -batch kho, thaum precision kuj welding los yog induction brazing khoom siv rau loj - teev automated ntau lawm.
Kev nyab xeeb yog qhov tseem ceeb hauv kev ua haujlwm soldering. Cov lus qhia hlau soldering feem ntau ua haujlwm ntawm qhov kub siab txog 400 degrees Celsius, thiab kev tuav tsis raug tuaj yeem ua rau kub hnyiab tau yooj yim. Tsis tas li ntawd, txhuas, rosin, thiab flux nyob rau hauv lub solder yuav tso tawm cov pa phem thaum kub kub. Yog li ntawd, cov kev npaj hauv qab no yuav tsum tau ua kom tiav ua ntej pib ua haujlwm soldering:
Ua ntej, xyuas kom thaj chaw ua haujlwm huv si, ruaj khov, tsis muaj cov khoom siv hluav taws xob, thiab muaj qhov cua zoo lossis cov khoom siv fume extraction. Thib ob, hnav cov looj tsom iav tiv thaiv thiab cua sov-cov hnab looj tes tiv thaiv kom tsis txhob muaj qhov sib tsoo los yog kub hnyiab los ntawm qhov kub thiab txias. Thib peb, ua tib zoo nyeem cov khoom siv phau ntawv thiab cov npe ntawm cov khoom siv sib xyaw kom paub meej tias lawv tsis muaj cov tshuaj txwv tsis pub. Plaub, xyuas cov hlau soldering, cables, thiab plugs rau kev puas tsuaj thiab muab cov hlau soldering ruaj ntseg rau ntawm ib qho chaw muag khoom. Hauv cov xwm txheej tsim khoom uas suav nrog Brazing Silver Hluav Taws Xob Cov Hluav Taws Xob, ntxiv siab -purity silver solder, flux, thiab argon gas tiv thaiv cov cuab yeej yuav tsum tau tiv thaiv cov nyiaj saum npoo oxidation los ntawm kev cuam tshuam cov khoom zoo.
Hauv kev ua haujlwm tiag tiag, lub hauv paus ntsiab lus ntawm "ua kom huv si ua ntej, tom qab ntawd cua sov, tom qab ntawd pub, thiab txias sai sai" yuav tsum ua raws. Ua ntej, siv dej cawv los yog ib lub tshuab ntxuav tshwj xeeb kom tshem tawm cov roj thiab oxide txheej los ntawm qhov chaw ntawm cov tooj liab thiab cov nyiaj sib cuag. Tom qab ntawd, preheat cov hlau soldering rau qhov kub thiab txias (feem ntau yog 300-380 degree), thiab ib txhij hu rau lub workpiece thiab solder nrog lub taub hau. Tshem tawm lub tshav kub tom qab lub solder tau tag nrho ntws. Rau cov ntoo khaub lig loj dua - ntu kev sib txuas xws li Copper Bar Silver Contact Attachments, vim yog cov cua kub ceev thiab tawg ntawm cov tooj liab, cov pa roj carbon monoxide yuav tsis muaj cua sov txaus. Nyob rau hauv cov ntaub ntawv no, ib tug high-power soldering chaw nres tsheb los yog nplaim brazing yuav tsum tau siv.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias koj yuav tsum tsis txhob sim ua haujlwm ntawm cov khoom siv hluav taws xob thaum lub sij hawm soldering los tiv thaiv kev luv luv los yog hluav taws xob shocks. Lub taub hau yuav tsum tau so tsis tu ncua nrog daim txhuam cev ntub dej los yog ntxuav cov ntaub kom tshem tawm cov oxides thiab carbides seem. Siv tweezers los yog clamps los tuav lub workpiece nyob rau hauv qhov chaw kom tsis txhob hlawv koj cov ntiv tes. Yog hais tias cov pob qij txha zoo li npub, kheej kheej, los yog taw tes, nws feem ntau qhia tias qhov kub thiab txias tsis txaus los yog tsis txaus preheating ntawm workpiece nto, yuav tsum tau resoldering.
Nyob rau hauv cov khoom siv hluav taws xob xws li cov keyboards, relays, thiab contactors, precision welding rau tooj liab qhov chaw yog cov txheej txheem tseem ceeb rau kev ua tiav kev ntseeg siab ntawm cov nyiaj sib cuag thiab tooj liab conductive qhov chaw. Cov txheej txheem feem ntau muaj xws li qhov chaw vuam, nyiaj brazing, thiab laser vuam. Resistance chaw vuam siv lub siab tam sim no los ua kom muaj Joule tshav kub ntawm qhov kev sib cuag, ua rau lub zos melting ntawm cov khoom los ua ib tug weld nugget, haum rau ceev sib dhos ntawm me me - cheeb tsam hu. Silver brazing siv cov nyiaj siv nyiaj-raws li cov khoom siv hlau nrog cov ntsiab lus melting qis dua cov hlau hauv paus, sau qhov sib koom ua ke los ntawm kev ua haujlwm capillary, muab cov txiaj ntsig zoo xws li kev sib txuas siab zog thiab kev ua haujlwm hluav taws xob ruaj khov.
Hauv kev tsim khoom loj, welded alumina tiv tauj cov rooj sib tham feem ntau ua tiav siv cov tshuab vuam tshuab. Cov cuab yeej muaj peev xwm tswj tau qhov vuam siab, tam sim no, thiab lub sijhawm kom ntseeg tau tias qhov sib sib zog nqus qhov tob thiab daim ntawv cog lus muaj zog rau txhua qhov sib cuag. Rau qhov tsis xwm yeem zoo li tus lossis loj workpieces, nyiaj sib cuag rau machined qhov vuam yuav tsum tau tsim tshwj xeeb electrodes thiab cov cuab yeej fixtures. Piv txwv li, thaum soldering nyiaj tiv tauj rau lub tshuab tooj liab ntsia hlau, nws yog ib qho tseem ceeb kom paub meej qhov kev sib raug zoo thiab lub siab sib xws; txwv tsis pub, misalignment lossis tsis tiav soldering yuav tshwm sim.
Tom qab vuam, lub welded silver contact machined los ua ke yuav tsum tsim nyog tom qab- ua thiab tshuaj xyuas. Ua ntej, cov dej seem seem raug ntxuav nrog cawv los tiv thaiv ntev - lub sij hawm corrosion. Qhov thib ob, kev soj ntsuam pom tau ua tiav: cov pob qij txha uas tsim nyog yuav tsum muaj qhov ci ntsa iab, tag nrho contour, thiab tsis muaj porosity lossis tawg. Rau machined ib feem silver contact brazed assemblies, thawb- rub quab yuam kev xeem los yog kev sib cuag tiv thaiv kev ntsuam xyuas kuj yuav tsum tau los xyuas kom meej lawv mechanical zog thiab conductivity. Nyob rau hauv siab -voltage hloov daim ntawv thov, tus nqi brazing ntawm hluav taws xob nyiaj brazing hu rau kev sib txuas yuav tsum tsis pub tsawg tshaj 85%, txwv tsis pub muaj overheating hauv zos yuav tshwm sim thaum siv.
Tsuas yog brazed silver contact assemblies uas tau dhau los ua pov thawj zoo tuaj yeem mus rau theem tom ntej los ua ke. Nws yog ib qho tseem ceeb kom paub meej tias cov khoom siv hluav taws xob sib txawv muaj qhov sib txawv ntawm cov txheej txheem vuam. Piv txwv li, automotive relays muaj cov kev xav tau kev vibration siab thiab yog qhov zoo tshaj plaws rau kev ua haujlwm vuam; thaum siab -voltage disconnecting keyboards vam khom ntau dua ntawm cov fusion txuas ntxiv ntawm cov nyiaj brazing. Yog li ntawd, cov txheej txheem engineers yuav tsum tsim cov ncauj lus kom ntxaws welding specifications raws li kev ua haujlwm tshwj xeeb.
