Vuamelectrode muaj ob feem, cov tub ntxhais thiab txheej.Cov tub ntxhais hlau vuam electrodes yog sab nraum cov xim (txheej) cov txheej txheem siab siv los ua tib zoo solder core.Ntau hom vuam, vuam core yog txawv.Vuam electrode core hlau tub ntxhais, txhawm rau kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm vuam, pob tw cov ntsiab lus tseem ceeb ntawm cov khoom hlau muaj cov cai nruj, tshwj xeeb tshaj yog rau cov ntsiab lus tsis zoo (xws li sulfur, phosphorus, thiab lwm yam), yuav tsum muaj. yuav tsum nruj txwv tsis pub tshaj cov khoom siv hauv paus.Electrode tshuaj hnab hu ua weld hlau core coated core.Vuam tub ntxhais hlau feem ntau muaj qee qhov ntev thiab txoj kab uas hla.Thaum soldering, vuam core muaj ob qhov teebmeem: Ua ntej, ua qhov vuam tam sim no, lub zog arc hloov mus rau hauv tshav kub, qhov thib ob core hlau nws tus kheej yog siv los ua cov hlau muab tub lim nrog cov kua molten niam txiv hlau fusion weld yog tsim.

Siab siv rau saum npoo ntawm txheej hu ua core solder txheej.Electrode txheej plays lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam.Kev siv cov tshuaj tsis muaj tshuaj tiv thaiv lub teeb ntawm daim tawv nqaij electrode vuam, cov txheej txheem vuam, cov pa oxygen thiab nitrogen hauv huab cua yuav ua rau muaj kev cuam tshuam loj heev ntawm cov hlau molten, cov hlau hlau thiab cov khoom muaj txiaj ntsig carbon, silicon, manganese oxide thiab nitride tsim ntawm ntau yam oxides thiab nitrides, thiab tseem nyob rau hauv weld, weld slag, los yog ua rau tawg.Cov yaj mus rau hauv cov pa roj yuav ua rau muaj qhov loj ntawm cov khoom siv vuam porosity, cov yam ntxwv no tuaj yeem ua rau cov khoom siv ntawm cov khoom siv vuam (lub zog, qhov cuam tshuam tus nqi, thiab lwm yam) txo qis, thaum lub vuam nkig.

SMAW vuam electrodes siv los ntawm txheej thiab vuam core muaj li ntawm ob qhov chaw.Thaum vuam, vuam electrode raws li ib sab tes, thiab los ntawm tus tsav arc tam sim no conduction nyhuv, thiaj li hais tias ntawm lub electrodes thiab lub hauv paus hlau nyob rau hauv ib tug nruam, ruaj arc, muab cua sov tsim nyog los yaj lub solder.Ntawm qhov tod tes, thiab raws li lub vuam muab tub lim hlau ntxiv rau qhov vuam los ua ib qho tseem ceeb ntawm cov hlau vuam.Raws li, qhov muaj pes tsawg leeg ntawm vuam zoo thiab vuam, cov tshuaj muaj pes tsawg leeg ntawm cov hlau vuam ncaj qha cuam tshuam rau cov khoom siv thiab lub cev.Tsis tas li ntawd, cov electrode kuj muaj kev cuam tshuam zoo rau kev ruaj ntseg ntawm cov tsos zoo ntawm cov vuam, cov txheej txheem vuam xws li vuam tsim tau.
