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 vuam ntau dua, tab sis cov khoom siv vuam siv feem ntau muaj cov alloy muaj qhov zoo zoo tag nrho.Beryllium tooj liab tuaj yeem welded rau nws tus kheej, 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.
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, cov ntaub ntawv nthuav tawm no tsuas yog qhia tau
Sab qab teb, ib qho kev ntsuam xyuas vuam tuaj yeem 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 ua haujlwm siab, qhov saum npoo yuav tsum tau ntxuav tas li.Cov kab mob kis tau tuaj yeem ua rau qhov kub thiab txias ntawm cov electrode, txo lub neej ntawm cov hlau electrode, ua rau cov khoom siv tsis zoo, thiab ua rau cov hlau sib txawv ntawm qhov chaw vuam.ua rau soldering los yog slag.Ib cov roj nyias nyias los yog cov khoom khaws cia yog txuas rau saum npoo, uas feem ntau tsis muaj teeb meem nrog kev ua haujlwm vuam, thiab beryllium tooj liab electroplated rau ntawm qhov chaw muaj teeb meem tsawg tshaj plaws hauv vuam.Beryllium tooj liab nrog ntau degreased los yog flushing los yog stamping lubricants tuaj yeem ntxuav tau hnyav.Yog hais tias qhov saum npoo yog xeb heev los yog qhov saum npoo yog oxidized los ntawm kev kho cua sov, nws 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.
