Vuam electrodes yog hlau hlau nrog ci ntawm cov tshuaj coatings.Tus pas nrig yog siv los txhawb nqa qhov vuam arc thiab muab cov hlau muab tub lim xav tau rau kev sib koom ua ke.Cov txheej tiv thaiv cov hlau los ntawm kev puas tsuaj, stabilizes lub arc, thiab txhim kho qhov vuam.Txoj kab uas hla ntawm cov hlau, tsawg dua txheej txheej, txiav txim siab qhov loj ntawm lub vuam pas nrig.Qhov no yog qhia nyob rau hauv feem ntawm ib nti xws li 3/32 ", 1/8", los yog 5/32."Qhov me me ntawm txoj kab uas hla txhais tau tias nws yuav tsum tau tam sim no tsawg dua thiab nws tso ib qho me me ntawm cov hlau muab tub lim.
Hom ntawm lub hauv paus hlau yog welded, cov txheej txheem vuam thiab tshuab, thiab lwm yam kev mob txiav txim siab hom vuam electrode siv.Piv txwv li, cov pa roj carbon tsawg lossis "me me steel" yuav tsum tau siv cov hlau vuam me me.Vuam cam khwb cia hlau, txhuas los yog tooj dag yuav tsum tau sib txawv vuam rods thiab khoom siv.
Lub flux txheej ntawm cov electrodes txiav txim seb nws yuav ua li cas thaum lub sij hawm vuam txheej txheem.Qee cov txheej txheem kub hnyiab thiab cov hluav taws kub hnyiab ua rau cov pa taws thiab ua raws li daim ntaub thaiv nyob ib puag ncig lub vuam "pas dej", tiv thaiv nws los ntawm huab cua puag ncig nws.Ib feem ntawm cov flux melts thiab sib tov nrog cov hlau thiab ces ntab cov impurities rau saum npoo.Cov impurities no hu ua "slag."Lub weld tiav lawm yuav nkig thiab tsis muaj zog yog tias tsis yog rau qhov flux.Thaum lub welded sib koom yog txias, lub slag tuaj yeem raug tshem tawm.Ib tug chipping rauj thiab hlau txhuam yog siv los ntxuav thiab tshuaj xyuas qhov vuam.
Cov hlau-arc vuam electrodes tej zaum yuav muab ua pawg li liab qab electrodes, lub teeb coated electrodes, thiab shielded arc los yog hnyav coated electrodes.Hom siv nyob ntawm cov khoom tshwj xeeb uas yuav tsum tau muaj xws li: corrosion resistance, ductility, siab tensile zog, hom puag hlau yuav tsum welded;thiab txoj hauj lwm ntawm cov weld uas yog tiaj tus, kab rov tav, ntsug, lossis saum taub hau.
