Qhov kev thov rau hlau hauv lub neej niaj hnub no tab tom nce ntxiv, thiab ntau yam khoom siv hlau siv hauv lub neej txhua hnub raug tsim tawm, uas yuav tsum tau vuam nrog cov tshuab vuam hluav taws xob. Ib qho tseem ceeb hauv cov txheej txheem no yog lub electrode lossis welding rod. Hauv cov txheej txheem arc welding, lub electrode ua hluav taws xob hauv qhov chaw kub siab, tom qab ntawd yaj, thiab thaum kawg muab tso rau hauv qhov sib koom ua ke ntawm cov khoom vuam. Xaiv cov welding rod raws li cov khoom siv ntawm cov khoom vuam. Lub electrode yog tsim los ntawm lub plawv hlau sab hauv thiab lub txheej sab nraud. Lub plawv vuam yog tsim los ntawm cov hlau hlau nrog lub cheeb thiab ntev teev tseg, uas yog cua sov thiab yaj los ntawm kev qhia txog hluav taws xob, thiab thaum kawg puv.
Qhov sib txawv ntawm cov khoom ua haujlwm los tsim ib qho kev sib txuas los txuas cov khoom ua haujlwm. Cov hlau carbon, cov hlau alloy thiab cov hlau tsis xeb yog cov khoom siv tseem ceeb rau kev vuam. Yuav kom ua tau raws li qhov yuav tsum tau ua vuam, muaj cov kev cai tshwj xeeb rau qhov zoo ntawm cov khoom siv ntawm lub hauv paus vuam thiab cov hom hlau, thiab kuj muaj cov cai nruj ntawm cov ntsiab lus ntawm qee cov hlau. Qhov no yog vim tias cov ntsiab lus ntawm cov hlau hauv lub hauv paus vuam yuav cuam tshuam rau qhov zoo ntawm qhov vuam.
Thaum ib tug neeg qhuas qhov ruaj khov ntawm lub choj hlau, qhov ntev ntawm lub qhov av, thiab qhov zoo nkauj ntawm lub nkoj loj hauv hiav txwv, nws yog ib qho tseem ceeb uas yuav tsum lees paub cov pas nrig me me uas pab txhawb rau lawv txoj kev tsim kho. Thaum lub pas nrig vuam raug qhib, nws muaj lub zog los coj ntau qhov chaw hlau ua ke los ua ib qho qauv sib koom ua ke. Lub pas nrig vuam sib koom ua ke ntau qhov kev faib tawm, sib sau ua ke cov khoom tawg, thiab ua kom cov ntu nyias nyias muaj zog. Nws yog qhov chaw ntawm lub zog tshiab, ci ntsa iab txhua qhov chaw nws hlawv.
