Cov Qws Welding yog ib qho cuab yeej tseem ceeb hauv kev vuam hlau arc, nrog rau AWS E7018 kev faib tawm sawv cev rau ib qho ntawm cov hom siv tau ntau yam thiab siv dav tshaj plaws. Lub electrode tshwj xeeb no, tseem hu ua J506Fe hauv cov qauv hauv tebchaws, yog hom hmoov hlau potassium hydrogen qis. Nws cov qauv yog tsim los tsim cov vuam zoo, muaj zog nrog qhov tsis zoo tsawg kawg nkaus, ua rau nws yog qhov kev xaiv zoo rau ntau yam kev tsim khoom dav dav thiab kev kho, los ntawm kev ua haujlwm hlau mus rau kev saib xyuas tshuab hnyav.
Lub ntsiab feature ntawm cov noCov Qws Vuamyog lawv cov hmoov hlau uas muaj hydrogen tsawg. Cov khoom sib xyaw no yog qhov tseem ceeb rau kev txo cov dej noo uas tuaj yeem ua rau hydrogen ua rau tawg hauv cov hlau vuam, tshwj xeeb tshaj yog rau cov hlau muaj zog lossis cov seem tuab. Kev suav nrog cov hmoov hlau ua rau muaj kev ua haujlwm zoo dua, ua rau muaj ntau cov hlau vuam los ntawm ib tus pas piv rau cov hom hmoov tsis yog hlau. Qhov no ua rau muaj kev tsim khoom ntau dua thaum tswj kev sib txuas zoo heev.
Ib qho txiaj ntsig zoo ntawm kev ua haujlwm ntawm E7018Cov Qws Vuamyog lawv qhov kev ua tau zoo tshaj plaws hauv kev vuam txoj haujlwm. Lawv tau tsim los siv rau txhua qhov chaw tiaj tus, kab rov tav, ntsug, thiab saum taub hau.,muab kev ywj pheej rau cov neeg vuam kom daws tau cov haujlwm nyuaj yam tsis tas hloov cov khoom siv. Lawv ua haujlwm tau zoo ntawm ob qho tib si Alternating Current (AC) thiab Direct Current (DC) fais fab. Qhov kev sib raug zoo ob qho no ua kom lawv siv tau nrog yuav luag txhua lub tshuab vuam, los ntawm cov khoom siv hauv kev lag luam mus rau cov tshuab hluav taws xob portable.
Cov khoom siv vuam uas tau los ntawm cov electrodes no paub txog lawv cov khoom siv kho tshuab zoo tshaj plaws thiab pom kev zoo nkauj. Lub hlaws vuam feem ntau yog du, nrog rau cov ripple zoo thiab yooj yim-rau-tshem tawm slag. Qhov tseem ceeb tshaj, cov hlau vuam ua rau muaj kev cuam tshuam siab, txawm tias nyob rau hauv qhov kub qis dua, thiab muab lub zog tensile zoo. Qhov kev sib xyaw ua ke ntawm qhov zoo nkauj thiab kev ntseeg tau ntawm cov khoom siv ua rau cov pas nrig no haum rau cov ntawv thov tseem ceeb uas qhov kev ua haujlwm vuam tsis tuaj yeem sib tham.
AWS E7018 (J506Fe) kev faib tawm sawv cev rau ib pawg ntawmCov Qws Vuamuas sib npaug ntawm kev ywj pheej ua haujlwm nrog cov txiaj ntsig zoo. Lawv lub peev xwm ua tau txhua qhov chaw, sib xws nrog ob qho tib si AC thiab DC, thiab cov yam ntxwv qis-hydrogen, siab deposition ua rau lawv yog qhov tseem ceeb siv tau hauv ntau lub chaw ua haujlwm thiab cov chaw tsim kho. Rau cov neeg vuam uas tab tom nrhiav lub electrode txhim khu kev qha, lub hom phiaj dav dav rau cov ntawv thov nyuaj, hom stick welding rod no tseem yog qhov kev xaiv txhim khu kev qha tas li.
