Lub tshuab vuam yuav tsum tau muab tso rau hauv av kom zoo ua ntej siv kom ntseeg tau tias muaj kev nyab xeeb ntawm tus kheej. Ua ntej siv lub tshuab vuam, siv 500V megohmmeter los ntsuas cov rwb thaiv tsev ntawm qhov siab -voltage sab ntawm lub vuam tshuab thiab cov casing; nws yuav tsum tsis pub tsawg tshaj 2.5 megohms ua ntej lub hwj chim. Thaum lub sij hawm tu, lub hwj chim yuav tsum raug txiav ua ntej qhib lub pob rau kev tshuaj xyuas. Lub tshuab vuam yuav tsum tau muab dej ua ntej vuam; kev ua haujlwm yog nruj me ntsis txwv tsis pub dej. Cov dej txias yuav tsum yog cov dej ua haujlwm ntawm qhov siab ntawm 0.15-0.2MPa thiab qhov kub ntawm 5-30 degree. Tom qab vuam hauv lub caij ntuj no, siv cov cua compressed los tshuab tawm cov dej los ntawm cov kav dej kom tiv thaiv kom tsis txhob khov thiab tawg.
Lub tshuab welding yuav tsum tsis txhob nyias los yog ntev dhau. Qhov hluav taws xob poob thaum lub vuam yuav tsum tsis pub tshaj 5% ntawm qhov pib voltage, thiab qhov pib voltage yuav tsum tsis txhob deviate ntawm lub hwj chim mov voltage los ntawm ± 10%. Hnav hnab looj tes, daim npog ntsej muag, thiab tsom iav kev nyab xeeb thaum ua haujlwm ntawm lub tshuab vuam kom tsis txhob muaj hluav taws kub hnyiab. zawv zawg qhov chaw yuav tsum tau lubricated zoo, thiab hlau spatter yuav tsum tau muab tshem tawm tom qab siv. Tom qab siv lub tshuab vuam tshiab rau 24 teev, nruj tag nrho cov ntsia hlau ntawm tag nrho cov khoom, ua tib zoo saib xyuas cov ntsia hlau txuas cov tooj liab hloov pauv thiab cov electrodes. Tom qab siv, tsis tu ncua tshem tawm cov oxides los ntawm electrode pas nrig thiab electrode caj npab kom ntseeg tau tias kev sib cuag zoo.
Yog tias AC contactor tsis ua haujlwm zoo thaum lub sijhawm vuam, nws qhia tias qhov hluav taws xob qis qis. Tus neeg siv yuav tsum xub daws qhov teeb meem ntawm lub hwj chim; siv lub tshuab tsuas yog tom qab cov khoom siv hluav taws xob zoo li qub. Nws yuav tsum raug sau tseg tias yog tias lub tshuab vuam tshiab tau ntsib qhov teeb meem tseem ceeb ntawm cov khoom lag luam tsis pub dhau ob lub lis piam ntawm kev yuav khoom, lub tshuab vuam tshiab lossis cov khoom tseem ceeb hloov pauv tuaj yeem muab tau. Lub tshuab vuam tshuab tseem ceeb yog them los ntawm ib qho - xyoo warranty, nrog rau kev pab tu lub sij hawm ntev -. Feem ntau, tom qab tus neeg siv ceeb toom rau cov chaw tsim khoom, kev pabcuam yuav muab rau hauv peb mus rau xya hnub, nyob ntawm qhov kev ncua deb. Kev puas tsuaj tshwm sim los ntawm tus neeg siv yuav tsis them raws li warranty. Cov khoom siv tau zoo thiab cov khoom puas yooj yim tsis raug them raws li kev lees paub.
Txij li thaum lub electrode tiv tauj cheeb tsam txiav txim siab tam sim no ceev, thiab cov resistivity thiab thermal conductivity ntawm cov khoom siv electrode cuam tshuam rau thaum tshav kub kub tsim thiab dissipation, cov duab thiab cov khoom ntawm cov electrode ho cuam tshuam rau kev tsim ntawm weld nugget. Raws li lub taub hau electrode deforms thiab hnav, qhov chaw sib cuag tau nce, thiab lub zog vuam txo qis. Oxides, av, roj, thiab lwm yam impurities ntawm lub workpiece nto nce kev tiv thaiv. Ib txheej oxide tuab heev tuaj yeem tiv thaiv tam sim no los ntawm kev hla. Localized conduction, vim muaj qhov ceev tam sim no, tuaj yeem ua rau tawg thiab kub hnyiab tau -tawm. Lub xub ntiag ntawm oxide txheej kuj tuaj yeem cuam tshuam qhov tsis sib xws ntawm cov cua sov ntawm ntau cov ntsiab lus weld, ua rau muaj kev hloov pauv hauv cov khoom siv vuam zoo. Yog li ntawd, ua tib zoo tu lub workpiece nto yog ib qho tseem ceeb los xyuas kom meej lub siab - zoo sib koom ua ke.
