KUJ YIAS NTAU RAU S355J0WP Weathering Hlau
Preheat & cuam tshuam qhov kub
Preheat rau100-150 degree(thickness-nyob nraum) txhawm rau tiv thaiv kom txhob muaj hydrogen-inducts tawg.
Tswj hwm tempsTsawg dua los yog sib npaug nrog 250 degreekom tsis txhob muaj kev muag zaub ntau dhau.
Muab Too Hlau Xaiv Kev Xaiv Hlau
Kev sivHuab Cua-Resistant Fillers(piv txwv li, aws E7018-W, ER70s-3 nrog CU / CR).
Zam kev tsis sib xws ua ke uas cov lus hais daws teeb meem.
Tsawg-hydrogen xyaum
Ci electrodes (350-400 DEGREE) kom tshem tawm cov dej noo.
Shield Welds los ntawm cov av noo (siv mig / gtaw nrog roj qhuav).
Thaum tshav kub kub tswj
Txwv rau0.5-2.0 KJ / hliTxhawm rau tiv thaiv kom tiv thaiv kab mob curegation thiab porosity.
Tsis txhob muaj lub sijhawm ntev Arc ntawm cov ntu nyias.
Post-Weld Saib Xyuas
Huv silag / puab tsaig kom ntseeg tau cov neeg patina tsim kom ntseeg tau.
Hla pwht tshwj tsis yog tias yuav tsum muaj kev ntxhov siab nyem (cov tshooj tuab).
Kev Tsim Qauv & Kev Xeem
Bevel tuab daim hlau (piv txwv li, 60℃v-groove) rau tag nrho nkag.
Txheeb xyuas Weld Rustity ntawmUt / ptthiab corrosion ntsuas.
