Hauv kev lag luam vuam, cov kws ua haujlwm feem ntau ntsib teeb meem xws li kev sib koom ua ke tsis txaus lossis corrosion- cuam tshuam tsis ua haujlwm. Piv txwv li, thaum welding tooj liab alloys los yog stainless hlau, ib qho kev xaiv tsis tsim nyog ntawm muab tub lim hlau tuaj yeem ua rau kev sib koom ua ke lossis txo cov hluav taws xob conductivity, yog li cuam tshuam cov cuab yeej siv tau ntev. Cov teeb meem no feem ntau tshwm sim los ntawm kev nkag siab yuam kev ntawm cov hauv paus ntsiab lus ntawm cov txheej txheem thiab tsis muaj kev ua kom zoo rau kev xaiv. Tsab ntawv xov xwm no tshawb txog cov ntsiab lus tseem ceeb ntawm Weldable Silver Contacts thiab muab cov lus qhia xaiv cov tswv yim los pab cov neeg nyeem txhim kho lawv cov kev txawj ntse thiab ua kom muaj siab -welds zoo.
Core Technical Principles of Silver Contact Tips
Silver Contact Buttons yog ib hom brazing muab tub lim hlau-cov khoom siv hlau siv los koom nrog cov ntaub ntawv hauv paus (xws li tooj liab, hlau, lossis stainless hlau) yam tsis tau yaj cov ntaub ntawv hauv paus lawv tus kheej. Lawv txoj haujlwm yog nyob ntawm kev sib txuas ntawm metallurgical: thaum cua sov, cov hlau muab tub lim melts thiab ntub rau saum npoo ntawm cov khoom siv hauv paus, sau cov kev sib koom ua ke ntawm kev ua haujlwm capillary los tsim ib daim ntawv cog lus ruaj khov thaum txias. Thaum cov nyiaj (Ag) ua lub luag haujlwm tseem ceeb - muab cov hluav taws xob siab thiab thermal conductivity - nws cov ntsiab lus melting ntshiab yog siab dhau (kwv yees li 960℃). Yog li ntawd, cov ntsiab lus xws li tooj liab (Cu), zinc (Zn), thiab tin (Sn) raug ntxiv los tsim cov hlau uas txo qis qhov melting point thiab optimizes kev ua tau zoo. Piv txwv li, Ag30CuZnSn shim muaj 30% nyiaj nrog cov seem uas muaj tooj liab, zinc, thiab tin, uas ua rau muaj qhov sib txawv ntawm 665-755 degree. Qhov kev tsim qauv tsim tau zoo ua tau raws li cov kev xav tau ntawm kev sib txuas rau tooj liab, hlau, thiab stainless hlau vim:
Silver cov ntsiab lus cuam tshuam kev ua haujlwm:Ib feem ntawm cov nyiaj ntawm 30% -45% (piv txwv li, Ag30CuZnSn lossis Ag45CuZnSn) sib npaug tus nqi nrog cov khoom siv hluav taws xob, ua rau nws tsim nyog rau cov ntawv thov kev lag luam.
Alloying ntsiab ua lub luag haujlwm tshwj xeeb:Copper txhim khu lub zog, zinc txo qhov melting point, thiab tin txhim kho wettability; ua ke, lawv xyuas kom muaj kev ruaj ntseg ntawm cov welded sib koom ntawm qhov kub thiab txias. Qhov tseem ceeb ntawm cov ntsiab lus melting yog nyob rau hauv qhov yuav tsum tau rau cov solder kom yaj hauv qab cov khoom siv melting point (xws li, tooj liab melts ntawm 1083 degree); qhov 665-755℃ntau ntawm Ag30CuZnSn tso cai rau kev tswj xyuas thiab txo qis deformation hauv tshav kub- thaj tsam cuam tshuam.
Hauv kev siv cov tswv yim, Cov Lus Qhia Hluav Taws Xob Hluav Taws Xob tsim cov pob qij txha los ntawm cov txheej txheem brazing (xws li nplaim taws lossis induction cua sov), ua tiav kev sib koom ua ke ntawm 200-300 MPa thiab superior corrosion kuj piv rau cov qauv solders. Qhov kev ua tau zoo no tshwm sim los ntawm cov nyiaj tsis zoo thiab cov hlau tsis sib xws, txawm hais tias qhov tshwm sim tiag tiag yog nyob ntawm kev tswj hwm kev sib xyaw.
Tswv yim rau xaiv Silver Contact Discs
Kev Xaiv Cov Khaub Ncaws Hluav Taws Xob yuav tsum muaj kev ntsuam xyuas zoo ntawm cov vuam xav tau kom tsis txhob muaj kev ua tsis tiav los ntawm kev xaiv tsis raug. Cov kauj ruam tseem ceeb suav nrog:
Matching welding cov ntaub ntawv:Ua ntej xaiv raws li cov khoom siv hauv paus. Piv txwv li, Round Silver Contacts yog tsim rau tooj liab thiab tooj liab alloys, steel, thiab stainless hlau vim lawv zoo wettability, whereas txhuas yuav tsum tau tshwj xeeb solder. Nrog rau cov khoom specifications kom paub meej tias compatibility (xws li, Ag30CuZnSn yog haum rau tooj liab alloys thiab hlau).
Analyzing lub melting point range:Cov txheej txheem vuam kub yuav tsum nyob hauv qab ntawm cov khoom siv lub hauv paus melting point. Thaum xaiv ib qho ntxig, sib piv nws cov ntsiab lus melting nominal (xws li, 665-755 degree) nrog cov cuab yeej cua sov. Cov ntsiab lus siab melting ntau dhau ua rau muaj zog siv zog, thaum cov khoom qis heev tuaj yeem ua rau ntxov melting ntxov.
Kev ntsuas qhov sib xyaw ua ke:Cov ntsiab lus Silver cuam tshuam rau tus nqi thiab kev ua haujlwm. Ntxig nrog 30–40% nyiaj (piv txwv li, Ag30CuZnSn) yog tus nqi- siv tau thiab tsim nyog rau kev siv dav dav; siab- qib nyiaj (piv txwv li, Ag45) muaj cov khoom siv hluav taws xob zoo dua tab sis tuaj ntawm tus nqi siab dua. Tshawb xyuas cov khoom tshwj xeeb thiab tus lej qauv kom paub meej cov ntsiab lus muaj pob tshab.
Xav txog cov duab thiab txheej txheem:Cov duab ntawm qhov ntxig (xws li, daim ntawv, sawb, lossis xaim) cuam tshuam rau kev siv yooj yim. Daim ntawv cov ntaub ntawv yog qhov zoo tagnrho rau kev siv lub tshuab vuam, thaum lub strips haum rau kev tuav haujlwm. Tsis tas li ntawd, ua kom muaj kev ntseeg siab ua ntej los ntawm kev xaiv cov khoom lag luam nrog cov ntsiab lus meej meej thiab cov ntaub ntawv soj ntsuam zoo los txo cov kev pheej hmoo ntawm cov khoom lag luam. Txheeb xyuas cov khoom ua raws: Ua ntej ntsuas kev ntsuas cov khoom tsim tawm hauv tsev kom txo cov nqi kev yuav khoom thiab xyuas kom ua raws li cov qauv tsim khoom (xws li ISO certification). Tsis txhob yuav cov khoom lag luam uas tsis muaj tus lej qauv lossis tsis muaj cov khoom sib xyaw.
Thaum lub sij hawm kev sim, solder wettability thiab lub zog sib koom ua ke tuaj yeem txheeb xyuas los ntawm cov qauv vuam kom ua raws li cov qauv kev lag luam (xws li AWS specifications).
Kev siv piv txwv ntawm Cov Ntawv Nyiaj Zoo Tshaj Plaws
Ag30CuZnSn Nyiaj Sib cuag Cov Lus Qhia ua qhov siv tau zoo rau kev xaiv khoom. Lawv cov muaj pes tsawg leeg-featuring 30% nyiaj thiab tooj liab-zinc-tin alloy- muab qhov sib txawv ntawm 665-755 degree, ua rau lawv haum rau vuam tooj liab alloys, hlau, thiab stainless hlau (xws li, rau cov khoom lag luam xws li bandsaw hniav). Raws li nyiaj-raws li alloy shims, lawv tau tsim los rau kev siv yooj yim hauv kev siv cov khoom siv. Cov shims no muaj kev ua haujlwm ruaj khov hauv kev ua haujlwm vuam txheej txheem, thiab kev sib koom ua ke lub zog ua tau raws li qhov nruab nrab ntawm kev lag luam, ua rau lawv muaj kev xaiv zoo rau cov engineers. Txawm li cas los xij, cov kev cai tshwj xeeb yuav tsum tau txiav txim siab thaum xaiv es tsis yog tso siab rau cov kev qhia dav dav.
