1. Ntev ntawm arc
Qhov ntev ntawm arc muaj feem cuam tshuam rau txheej txheej txheej thiab txheej tuab ntawm Q355 Kwm Kev Tshawb Fawb Hlau lossis electrode. Txawm li cas los xij, ARC luv yuav tsum tau saws kom deb li deb tau, tshwj xeeb tshaj yog hydrogen q355 Weathering hlau daim ntawv hlau lossis electrode. Ib lub arc ntev yuav ua rau porosity. Lub ARC luv luv tuaj yeem zam cov pa roj teeb meem xws li O2 thiab N2 hauv cov cua los ntawm kev siv tshuaj o weld ua kom zoo nkauj, uas yuav cuam tshuam rau kev ua kom zoo ntawm Q355 Wilding Wild Steel Sheet.
2. Vuam Ceev
Qhov tsim nyog vuam ceev yog tias Q355 lub ntsej muag dav hlau hlau lossis hluav taws xob ntawm cov khoom uas muaj kev hloov pauv, yog li tsis muaj tus qauv tuaj yeem ua.
Q355Gnh Weathering steel daim ntawv tswj xyuas qhov tsim nyog vuam kom txaus, yog li txhua yam roj av tau npog qhov tsim ntawm sloag suav thiab porosity nyob rau hauv weld.
Thaum q355 sab nraud wild steel ntawv yog siv rau vuam, yog tias kev txav nrawm nrawm dua thaum lub vuam ib feem yog qhov txias, uas yuav ua rau tawg hauv Weld.
