A333-6 steel yeeb nkab yog cov hlau tsis tshua muaj kub.Qhov tsawg kawg nkaus kub ntawm 70 ° C. Feem ntau normalized los yog normalized thiab tempered lub xeev tsum.
A333-6 steel carbon cov ntsiab lus qis dua, yog li hardened qhov nyiam thiab txias cracking nyiam yog me me.Cov ntaub ntawv toughness thiab ductility yog zoo dua, feem ntau nyuaj los tsim hardening thiab tawg, weldability zoo, xaiv W707Ni electrode nrog El cov imports ntawm hlau TGS 1N, siv argon ITU vuam.Los xyuas kom zoo toughness ntawm welded pob qij txha.
Preheat
Thaum lub ambient kub qis dua 5 ° C yuav tsum tau weldment preheating.Preheat qhov kub ntawm 100-150 oC: Preheat qhov ntsuas ntawm welds ntawm txhua sab ntawm 100 hli;cua sov oxyacetylene nplaim (neutral nplaim) ntsuas kub ntsuas ntsuas ntsuas kub ntawm 50 ~ 100 hli los ntawm qhov nruab nrab ntawm qhov vuam.Cov ntsiab lus ntsuas sib npaug sib npaug, txhawm rau tswj qhov kub kom zoo dua.
