Resistance welding yog ib qho kev txhim khu kev qha, tsis tshua muaj nqi, thiab siv tau zoo ntawm kev sib koom ua ke ob lossis ntau daim hlau ua ke.Txawm hais tias tsis kam vuam yog cov txheej txheem vuam tiag tiag, tsis muaj cov hlau muab tub lim, tsis muaj roj vuam.Tsis muaj cov hlau ntau dhau los tshem tawm tom qab vuam.Txoj kev no yog tsim rau kev tsim khoom loj.Cov welds yog ruaj thiab NW nyuam qhuav pom.
Keeb kwm, kev siv vuam vuam tau siv tau zoo los koom nrog cov hlau tsis muaj zog xws li hlau thiab npib tsib xee alloys.Cov hluav taws xob ntau dua thiab thermal conductivity ntawm tooj liab alloys ua rau cov vuam ntau nyuaj, tab sis cov khoom siv vuam siv feem ntau muaj cov hlau nplaum zoo zoo tag nrho.Nrog rau cov txheej txheem vuam zoo, beryllium tooj liab tuaj yeem welded rau nws tus kheej, mus rau lwm yam tooj liab alloys, thiab rau hlau.Copper alloys tsawg dua 1.00mm tuab yog feem ntau yooj yim rau solder.
Resistance vuam txheej txheem feem ntau siv rau vuam beryllium tooj liab Cheebtsam, chaw vuam thiab projection welding.Lub thickness ntawm lub workpiece, cov khoom siv alloy, cov cuab yeej siv thiab cov txheej txheem saum npoo yuav tsum txiav txim siab qhov tsim nyog rau cov txheej txheem.Lwm cov txheej txheem kev siv vuam vuam siv feem ntau, xws li nplaim vuam, taub qab vuam, vuam vuam, thiab lwm yam, tsis yog siv rau tooj liab alloys thiab yuav tsis tham txog.
Copper alloys yooj yim rau braze.
Cov yuam sij hauv kev ua haujlwm vuam yog tam sim no, siab thiab lub sijhawm.Kev tsim cov khoom siv hluav taws xob thiab kev xaiv cov khoom siv electrode tseem ceeb heev kom ntseeg tau tias qhov vuam zoo.Txij li thaum muaj ntau cov ntaub ntawv ntawm kev tiv thaiv vuam ntawm cov hlau, ntau qhov yuav tsum tau ua rau vuam beryllium tooj liab qhia ntawm no xa mus rau tib lub thickness.Kev tiv thaiv vuam tsis yog ib qho kev tshawb fawb tseeb, thiab cov khoom siv vuam thiab cov txheej txheem muaj kev cuam tshuam zoo rau kev vuam zoo.Yog li ntawd, nthuav tawm ntawm no raws li ib qho kev qhia nkaus xwb, ib qho kev ntsuam xyuas vuam siv tau los txiav txim siab qhov zoo tshaj plaws vuam kev mob rau txhua daim ntawv thov.
Vim tias feem ntau ntawm cov khoom ua haujlwm saum npoo av muaj cov hluav taws xob tsis zoo, qhov chaw yuav tsum tau ntxuav txhua hnub.
Qhov saum npoo yuav ua rau kom qhov kub thiab txias ntawm cov electrode, txo lub neej ntawm lub taub hau electrode, ua rau qhov chaw siv tsis tau, thiab ua rau cov hlau.
Deviating los ntawm qhov chaw vuam, ua rau cov welds cuav lossis cov seem ntawm cov pob qij txha welded.Ib cov roj nyias nyias los yog cov tshuaj tiv thaiv corrosion yog txuas rau saum npoo, thiab feem ntau tsis muaj teeb meem nrog kev ua haujlwm vuam.Lub beryllium tooj liab electroplated rau ntawm qhov chaw muaj teeb meem feem ntau hauv vuam.
ob peb.
Beryllium tooj liab nrog ntau tshaj uas tsis yog-greasy los yog flushing los yog stamping lubricants yuav hnyav ntxuav.Yog hais tias qhov saum npoo yog xeb
Hnyav corroded los yog maj mam kho qhov chaw oxidizes, thiab yuav tsum tau ntxuav kom tshem tawm cov oxide.Tsis zoo li cov pom liab-xim av tooj liab oxide heev
Nyob rau tib lub sijhawm, pob tshab beryllium oxide ntawm lub strip deg (tsim los ntawm kev kho cua sov hauv ib qho inert lossis txo cov roj) yog qhov nyuaj rau kev kuaj xyuas, tab sis nws yuav tsum tau muab tshem tawm ua ntej vuam.
