Welding Corten Steel: Kev taw qhia txog kev siv thiab ua
Vuam Corten steel xav tau qee qhov kev txiav txim siab vim nws qhov tshwj xeeb alloy muaj pes tsawg leeg thiab qhov tseem ceeb ntawm kev tswj hwm nws cov corrosion- tiv taus cov khoom. Thaum Corten steel tuaj yeem welded siv cov txheej txheem txheej txheem, nws yog ib qho tseem ceeb los xaiv cov ntaub ntawv muab tub lim thiab ua raws li cov txheej txheem vuam kom raug.
Vuam txheej txheem
Corten steel tuaj yeem welded siv cov qauv zoo li Shielded Hlau Arc Vuam (SMAW), Gas Metal Arc Vuam (GMAW), thiab Flux-Cored Arc Vuam (FCAW). Qhov kev txhawj xeeb tseem ceeb thaum lub sij hawm vuam yog kom tsis txhob qhia qhov tsis xws luag hauv corrosion- txheej tiv thaiv thiab xyuas kom meej tias cov cheeb tsam welded muaj cov corrosion kuj zoo ib yam li lub hauv paus hlau.
Filler Materials
Kev siv cov khoom muab tub lim zoo yog qhov tseem ceeb thaum vuam Corten steel. Rau ntau daim ntawv thov, cov hlau muab tub lim yuav tsum yog qib huab cua zoo sib xws, feem ntau sib piv cov tshuaj muaj pes tsawg leeg ntawm Corten steel. Qhov no yuav pab xyuas kom meej tias cov hlau weld muaj qhov zoo sib xws rau cov khoom siv hauv paus. Qee zaum, huab cua tshwj xeeb-qib vuam pas nrig lossis cov xov hlau raug pom zoo.
Preheating thiab Post-Kev txiav txim siab Weld
Preheating feem ntau tsis tsim nyog rau Corten steel tshwj tsis yog nws tau siv rau hauv cov ntu tuab lossis hauv qhov txias txias. Txawm li cas los xij, kev tswj xyuas cov cua sov kom zoo yog qhov tseem ceeb kom tsis txhob tawg lossis lwm yam tsis xws luag. Post-weld heat treatment (PWHT) feem ntau tsis tas yuav tsum tau tshwj tsis yog tias tau teev los ntawm cov qauv tsim, tab sis yuav tsum tau saib xyuas kom tso cai rau cov welds txias kom txias kom tsis txhob muaj kev ntxhov siab.
