E7018 electrodeyog cov pa roj carbon zoo nrog roj carbon electrode nrog hlau hmoov thiab tsawg-hydrogen potassium hom txheej txheej. Nws cov arc khov kho yog qhov zoo, thiab nws tsis yooj yim los tsim cov khoom siv hlau nplaum. Lub weld yog qhov zoo thiab zoo nkauj, tsis sib kis me me, yooj yim tshem tawm slag, thiab lub weld tau zoo dua Qes-kub ua kom nruj thiab tawg tsis kam, ob leeg AC thiab DC, tuaj yeem txuas rau hauv txhua txoj haujlwm.
Ib lub tshuab hluav taws xob nrog 5, 6 lossis 8 ntawm qhov kawg ntawm txoj cai yog hom-tsawg-hydrogen hom electrode. Cov hluav taws xob no tshwj xeeb ua rau muaj cov ntsiab lus hydrogen hauv weld qhov kawg. Kev ntsuas kom txo tau cov ntsiab lus hydrogen yuav tsum tau them sai sai los ntawm kev ntxuav qhov chaw sib koom tes, kev sib koom tes tsim, thiab cov hlau txuas tsis txuas ntxiv. Thaum siv E7018 electrode rau vuam, txhawm rau tiv thaiv hydrogen los ntawm kev tso rau hauv lub weld, qhov ntxeev ntawm ntawm qhov electrode yuav tsum khaws kom qhuav. Thaum lub thawv ntim ntawm lub vuam pas nrig tau qhib, nws cov flux yuav pib nqus noo noo hauv huab cua. Tom qab kwv yees li 4 teev ntawm kev cuam tshuam ntawm huab cua, qhov kev ua tau zoo ntawm txheej flux yuav kho tau. Yog tias qhov no tshwm sim, cov electrode yuav tsis ua nws txoj haujlwm ua haujlwm kom tau zoo, tshwj xeeb tshaj yog thaum vuam high-lub zog thiab cov tub ntxhais siab tsawg. Yog tias koj siv hluav taws xob nrog qhov ua kom H4R tshiab, nws yuav ua rau muaj kev ua tau zoo hauv huab cua li 9 teev hloov ntawm 4 teev.
Txij li E7018 electrode yooj yim nqus cov dej noo, nws muaj nyob rau hauv qhov cub hluav taws xob kom qhuav. Cov nqaj hlau txuas nyob rau hauv cov huab cua tuaj yeem rov ua dua ntawm 350 ～ 400 ℃ rau 1h ～ 2h. Txhawm rau kom rov qab tsim cov khoom ntawm nws cov tawv nqaij kho mob. Cov pa roj carbon qes qis tuaj yeem siv tau nrog welded E7018 electrode, tab sis qhov kawg weld lub zog yuav tsis muaj qhov siab txaus.
