E7018 electrode yog cov pa roj carbon zoo nrog cov hmoov hlau thiab cov hlau tsis muaj roj thiab cov pa roj carbon fiber ntau hom. Nws cov arc khov kho tau zoo, nws tsis yooj yim los tsim kev sib nqus, vuam vuam yog qhov zoo thiab zoo nkauj, tsis tshua muaj qhov yooj yim, yooj yim tshem tawm slag, thiab lub vuam vuam tau zoo dua kub tsis tshua muaj siab thiab tawg tsis kam, ob leeg AC thiab DC, tuaj yeem welded nyob rau hauv txhua txoj haujlwm.
Ib lub tshuab hluav taws xob nrog 5, 6 lossis 8 ntawm qhov kawg ntawm tus lej yog qhov muaj hluav taws xob tsawg-hydrogen. 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, los tiv thaiv hydrogen los ntawm kev tso rau hauv qhov 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. Thaum kis nrog cua rau txog 4 teev, qhov kev ua tau zoo ntawm txheej flux yuav kho. Yog tias qhov no tshwm sim, lub tshuab nqaj hlau yuav tsis ua nws txoj hauj lwm txuas ntxiv, tshwj xeeb tshaj yog thaum vuam high-lub zog thiab cov hlau qis me. Yog tias koj tab tom siv electrode nrog H4R cov ntawv tshiab, nws yuav ua rau muaj kev ua tau zoo hauv huab cua rau 9h hloov 4h.
Txij li E7018 vuam pas nrig yooj yim nqus dej noo, nws tau muab cia rau hauv txoj hlua hlau ua kom qhuav qhov cub. 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 tsawg kawg tuaj yeem txuas nrog lub E7018 electrode uas tsis tau ci, tab sis qhov kawg weld lub zog yuav tsis txaus.
