Vim li cas brazing cov txheej txheem nyiam rau kev ua cov khoom sib cuag nyiaj?

Txhawm rau kom nkag siab brazing, nws yog ib qho tseem ceeb ua ntej kom meej nws cov ntsiab lus. Hauv kev tsim thiab ua tiav ntawm Welded Ag Contact Assemblies, brazing yog ib qho ntawm cov txheej txheem kev sib txuas tseem ceeb. Brazing yog siv cov hlau muab tub lim (splatter hlau) nrog lub melting point qis dua lub hauv paus hlau. Cov hlau muab tub lim yog rhuab kom yaj, thiab cov kua muab tub lim hlau ntub cov hlau hauv paus, ua rau qhov sib koom ua ke, thiab diffuses nrog lub hauv paus hlau kom tiav qhov kev sib txuas. Tsis zoo li fusion vuam, lub hauv paus hlau tseem muaj zog thoob plaws hauv cov txheej txheem brazing. Piv nrog rau lub siab vuam, brazing tsis tas yuav tsum tau siv lwm lub zog rau lub workpiece, ua rau nws cov txheej txheem cov yam ntxwv txawv heev. Qhov kev sib txuas uas tshwm sim yog hu ua brazed seam.

Cov txheej txheem brazing tiav muaj cov txheej txheem kev khiav hauj lwm, uas yog ib qho tseem ceeb ua ntej kom ntseeg tau qhov kev sib txuas zoo ntawm Precision Vuam rau Copper Parts. Cov workpieces uas tau dhau los ua qhov chaw tu yog feem ntau sib sau ua ke siv txoj kev sib tshooj, nrog rau cov hlau muab tso rau ib ncig ntawm kev sib koom tes lossis hauv qhov sib txawv. Tom qab tag nrho cov sib dhos yog rhuab mus rau me ntsis saum toj no lub melting point ntawm brazing muab tub lim, cov muab tub lim hlau pib yaj thaum lub hauv paus hlau tseem unmelted. Cov kua ua kua hlau ua rau lub qhov khoob ntawm lub workpieces nyob rau hauv capillary nkaus. Tom qab ntawd, cov kua muab tub lim hlau thiab lub hauv paus hlau yaj thiab diffuse nrog ib leeg. Thaum lub sib dhos txias thiab solidifies, ib tug ruaj khov brazed sib koom ua ke yog tsim.

Cov hlau muab tub lim yog ib qho tseem ceeb muab tub lim hlau hauv cov txheej txheem brazing thiab cov khoom tseem ceeb cuam tshuam rau kev ua haujlwm ntawm Welded Silver Contact Machined Assembly. Kev lag luam tau tsim kom muaj kev sib koom ua ke thiab nruj heev rau cov khoom siv brazing. Ua ntej, lub melting point ntawm cov muab tub lim hlau yuav tsum qis dua lub melting point ntawm lub hauv paus hlau ntawm lub workpiece; qhov no yog lub hauv paus rau kev vam meej brazing. Thib ob, cov hlau muab tub lim yuav tsum muaj qhov ntub dej zoo kom ntseeg tau tias ntws mus rau hauv qhov sib koom ua ke. Nyob rau tib lub sijhawm, cov hlau muab tub lim yuav tsum muaj peev xwm tsim kom muaj kev sib cais thiab diffusion nrog lub hauv paus hlau, thiab kev sib koom ua ke zaum kawg yuav tsum ua kom tau raws li cov qauv kev siv tshuab, lub cev, thiab tshuaj lom neeg.

Raws li cov ntsiab lus melting ntau, cov hlau muab tub lim tuaj yeem muab faib ua ob pawg tseem ceeb: cov khoom siv tawv tawv thiab cov khoom muag muag. Hard muab tub lim hlau yog hom siv ntau tshaj plaws hauv kev tsim Machined Part Silver Contact Brazed Assembly. Brazing muab tub lim hlau xa mus rau cov hlau muab tub lim nrog lub melting point tshaj 450 degree. Cov hom muaj xws li txhuas-raws li, tooj liab-raws li, nyiaj-raws li, thiab npib tsib xee-raws li alloys. Brazing tiav siv brazing muab tub lim hlau yog hu ua nyuaj brazing. Lub zog sib koom ua ke tuaj yeem ncav cuag ntau dua 200 MPa, nthuav tawm cov khoom zoo heev -cov kabmob muaj peev xwm thiab tsim nyog rau ntau yam nyuaj thiab siab -kev ntxhov siab ntawm kev lag luam tivthaiv kev ua haujlwm scenarios.

Sib txawv brazing muab tub lim hlau muaj cov khoom sib txawv thiab kev siv; Kev xaiv kom raug yog qhov tseem ceeb rau kev txhim kho tag nrho qhov zoo ntawm Brazed Silver Contact Assembly. Copper-raws li cov hlau muab tub lim muab cov nqi zoo tag nrho- ua tau zoo thiab tsim nyog rau kev sib tsoo ntau yam khoom siv hlau. Silver-raws li cov khoom siv hlau muaj ntau yam kev siv, nthuav tawm cov khoom zoo heev, hluav taws xob thiab thermal conductivity, thiab corrosion kuj, thiab tuaj yeem braze qis- carbon steel, stainless hlau, tooj liab, thiab tooj liab alloys. Aluminium-raws li cov hlau yog siv tshwj xeeb rau kev koom nrog txhuas thiab aluminium alloy workpieces, thaum npib tsib xee-raws li cov hlau feem ntau yog siv nyob rau hauv siab - kub thiab corrosive tshwj xeeb ua haujlwm ib puag ncig.

Brazing, nrog nws qhov zoo ntawm kev sib koom ua ke muaj zog thiab ruaj khov, yog siv dav hauv kev ua haujlwm ntawm ntau yam khoom siv thiab txhawb nqa kev lag luam loj ntawm Electric Welded Silver Contact Assembly. Dhau li ntawm cov khoom siv nyiaj sib cuag, cov khoom ua haujlwm raug kev ntxhov siab thiab kev ua haujlwm ntawm qhov kub thiab txias, xws li cov tsheb kauj vab, cov cuab yeej carbide, thiab cov khoom siv tho, feem ntau ua tiav siv brazing. Siv cov khoom zoo heev ntawm ntau yam hlau brazing muab tub lim, cov pob qij txha brazed tuaj yeem tiv taus ntev - lub sijhawm thauj khoom, qhov kub thiab txias hloov pauv, thiab kev tshaj tawm corrosion, ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom lag luam.

Kev sib txuas cov cuab yeej zoo thiab cov yam ntxwv ua haujlwm ntawm ntau yam brazing muab tub lim hlau,Welded Ag Contact Assembliesyog tsim los siv mature brazing thev naus laus zis, ua rau cov pob qij txha muaj zog, zoo heev hluav taws xob thiab thermal conductivity, thiab superior corrosion kuj thiab stability. Lawv haum rau ntau yam kub thiab tsis kub thiab hnyav - lub luag haujlwm ua haujlwm, ua rau lawv siab - cov khoom zoo rau kev tswj hluav taws xob. Peb zoo siab tos txais cov neeg siv khoom los nug thiab sib tham txog kev cai- cov khoom tsim.
