(1) Compression txuas. Compression kev twb kev txuas, tseem hu ua crimping, yog ib tug tsis yog - tshem tawm kev twb kev txuas txoj kev. Nws yog cov txheej txheem uas siv cov cuab yeej tshwj xeeb los siv lub siab rau cov khoom siv sib txuas thiab cov khoom siv hluav taws xob, thiab cov yas deformation yog tsim los ntawm kev ntxhov siab, thiaj li txuas cov conductors thiab cov khoom sib txuas.
(2) Mechanical kev twb kev txuas. Cov txheej txheem ntawm kev sib txuas ntawm tus neeg xyuas pib thiab cov khoom siv sib txuas los ntawm lub siab tsim los ntawm cov ntsia hlau nruj, lub caij nplooj ntoos hlav torsion los yog lub npoo - zoo li tus qauv ntawm cov khoom siv nws tus kheej yog hu ua kev sib txuas tshuab. Txoj kev sib txuas no yog tshem tau. Qhov zoo ntawm kev sib txuas ntawm cov neeg kho tshuab yog cov txheej txheem yog qhov yooj yim thiab tuaj yeem siv rau kev ua haujlwm nyob. Cov hlau siv rau kev sib txuas tshuab qee zaum muaj cov qauv xov, uas tuaj yeem" tom" qhov saum npoo ntawm tus neeg xyuas pib nruj nruj thaum lub bolts yog nruj, thiaj li kom tau txais cov khoom zoo thiab cov khoom siv hluav taws xob.
(3) Solder kev twb kev txuas. Soldering kev sib txuas yog cov txheej txheem qub ntawm kev sib txuas conductors. Siv cov tin - plated txuas cov kav dej thiab qhov hluav taws xob stalks nrog cov qhov qhib lossis lub qhov dej, thiab sau cov molten solder (50% txhuas thiab tin) ntawm cov conductors, stubs lossis qhov hluav taws xob stalks kom tiav cov neeg xyuas pib sib txuas. Kev sib txuas ntawm solder tsuas yog tsim rau kev sib txuas ntawm tooj liab.
Qhov tsis zoo ntawm kev sib txuas yog tias thaum lub sijhawm luv luv - Circuit Court txhaum tshwm sim, qhov ntsuas kub tsuas yog 160 degree. Yog tias qhov kub thiab txias heev, lub solder yuav yaj thiab poob, thiab txawm tias qhov sib koom ua ke yuav raug desoldered.
(4) Fusion vuam txuas. Fusion welding yog ib txoj hauv kev siv cov khoom siv vuam los ua kom muaj qhov kub thiab txias kom yaj cov conductors kom ua tiav kev sib txuas. Qhov kom zoo dua ntawm fusion vuam yog tias nws tsis nce txoj kab uas hla ntawm tus neeg xyuas pib ntawm kev sib txuas, uas yog tshwj xeeb tshaj yog tsim rau kev ua kom yooj yim cable txuas. Lub argon arc vuam kev twb kev txuas tshuab siv rau kev sib txuas ntawm loj - seem aluminium core cable conductors yog fusion vuam kev twb kev txuas. Vim tias argon arc vuam txheej txheem kev sib txuas yog qhov nyuaj, cov khoom siv vuam tshwj xeeb yuav tsum tau ua, thiab cov kws tshaj lij yuav tsum tau kawm tshwj xeeb, cov txheej txheem no tsis tshua siv.
Ib qho yooj yim fusion vuam kev sib txuas tshuab yog hu ua thermite fusion vuam, los yog" flux - coated vuam". Txoj kev fusion welding no tsis xav tau cov khoom siv vuam, tab sis siv granular tooj liab oxide thiab txhuas tso rau hauv pwm tshwj xeeb. Tom qab hluav taws kub hnyiab, cov tshuaj tiv thaiv hnyav tshwm sim, ua rau tooj liab thiab txhuas oxide, thiab tib lub sijhawm tso tawm cua sov ntau.
Nws cov tshuaj tiv thaiv formula yog:
Cov tshuaj tiv thaiv no tuaj yeem nce qhov kub ntawm cov pwm tshwj xeeb mus rau ib puag ncig 2500 degree, yog li ua kua tooj liab, vuam cov cable conductors, thiab alumina slag ntab saum npoo. Thaum ua haujlwm, cov txheej txheem fusion welding no ua rau cov pa choking uas yuav tsum tau dissipated los ntawm kev yuam kom tso pa tawm.
