S355555555555555555555555555555555555555555555555555555555555555555555555555 oot cov tooj liab, npib tsib xee thiab lwm yam nyob rau hauv lub vuam oxidation, yog li tiv thaiv cov oxidation oxidation thiab matrix. Thaum cov pa roj carbon ntawm s35555j2wp huab cua kub steel phaj yog qhov siab dua, lub zog txias ntawm cov cua sov muaj ntau dua, thiab cov hluav taws xob ua kom zoo nkauj ntawm S355Sj2WP WorirD Steel Phaj yog hla.
Yog li yuav ua cas los tsim welded welded welded s355j2Wp Weather Hlau Hlau? Peb tuaj yeem ua cov ntsuas hauv qab no:
1. Xaiv cov theem pib qis hydrogen ntau hom electrode thiab flux. Qhov yooj yim tsawg hydrogen electrode thiab flux vuam sib koom ua ke muaj cov ntsiab lus hydrogen, zoo desulfurization thiab phosphorus thaj chaw thiab kev cuam tshuam zoo heev.
2. Npaj ntsug vuam ua ntu zus. Lub hauv paus ntsiab lus yog tias feem ntau cuab tam tau welds tuaj yeem welded nyob rau hauv cov xwm txheej ntawm tsawg stiffness mus ntxiv txo cov huab cua kub vuam kev ntxhov siab.
3. Preheating ua ntej vuam, qeeb cua txias lossis kev kho cua sov tom qab vuam. Preheating ua ntej vuam yog ib qho kev ntsuas tseem ceeb los tiv thaiv kev ua kom muaj qhov txias txias ntawm lub zog loj. Kev kho kom sov los yog kev kho kom sov tom qab vuam kiv yuav ua rau lub micrustrusing tag nrho, txhim kho micriviture kev ntxhov siab, txo cov kev ua kom sov, yog li txo lub vuam txias cracking li.
