Ah32 / Ah36 Shipbuilding Material Marine Steel Phaj

Toughness thiab Plasticity ntawm tshav kub - cuam tshuam Zone (HAZ)
Thaum qhov kev faib ua feem ntawm ferrite nyob rau hauv kub - dov steel daim hlau yog siab, lub toughness thiab plasticity ntawm tshav kub - cuam tshuam cheeb tsam (HAZ) thaum lub sij hawm vuam txheej txheem yog zoo dua. Qhov no yog vim ferrite nws tus kheej muaj zoo toughness thiab plasticity. Thaum lub sij hawm welding thermal voj voog, ferrite nyob rau hauv tshav kub - cuam tshuam cheeb tsam tuaj yeem tiv taus cov thermal stress generated los ntawm vuam thiab tsis tshua muaj kev tawg.
Piv txwv li, thaum arc vuam siv los welding kub - dov steel daim hlau nrog cov feem ntau ntawm ferrite, thaum lub sij hawm txias txheej txheem ntawm tshav kub - cuam tshuam cheeb tsam, ferrite theem yuav txo tau lub thermal stress los ntawm nws tus kheej yas deformation, txo qhov tshwm sim. ntawm kub - tawg tsim. Ntxiv mus, vim lub toughness ntawm ferrite, txawm yog hais tias tus qauv ntawm lub tshav kub - cuam tshuam cheeb tsam hloov mus rau ib tug tej yam, cov khoom tseem muaj peev xwm tuav tau zoo puas.

Lub zog sib tw ntawm Welded Joint
Tom qab welding, lub zog sib piv ntawm cov welded sib koom ua ke ntawm kub - dov steel phaj nrog ib tug siab feem ntawm ferrite yog zoo tagnrho. Vim tias lub zog ntawm ferrite yog qhov ruaj khov, tom qab vuam, lub zog ntawm kev sib koom ua ke tuaj yeem phim cov khoom siv hauv paus zoo. Qhov no yog vim hais tias nyob rau hauv lub vuam txheej txheem ntawm steel daim hlau mas tsim los ntawm ferrite, lub zog tsis hloov heev vim theem transformation thiab lwm yam.
Piv txwv li, nyob rau hauv qee qhov kev siv vuam cov qauv, xws li kev tsim cov qauv hlau, thaum kub dov steel phaj nrog cov feem ntau ntawm ferrite yog siv rau vuam, lub zog ntawm cov welded sib koom ua tau raws li cov qauv tsim, thiab lub sij hawm ntev. kev thauj khoom, qhov txo qis hauv lub zog ntawm kev sib koom ua ke yog me me, ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm cov qauv.

Adaptability rau vuam txheej txheem
Kub - dov steel daim hlau nrog cov feem ntau ntawm ferrite muaj zog adaptability rau vuam txheej txheem. Lawv tuaj yeem hloov mus rau ntau txoj kev vuam, xws li phau ntawv arc vuam thiab roj-shielded vuam. Qhov no yog vim lub cev thiab tshuaj lom neeg cov khoom ntawm ferrite yog qhov ruaj khov, thiab nws qhov kev ua haujlwm vuam tsis hloov pauv ntau nyob rau hauv qhov sib txawv vuam kub - cov khoom siv nkag.
Piv txwv li, thaum cov roj-shielded welding yog siv los welding kub - dov steel daim hlau nrog ib tug loj feem ntawm ferrite, los ntawm tsim nyog kho welding tsis (xws li welding tam sim no, voltage, vuam ceev, thiab lwm yam), nws yog ib qho yooj yim mus nrhiav tau. high-zoo welded sib koom ua ke. Ntxiv mus, thaum lub sij hawm vuam txheej txheem, vim qhov ruaj khov ntawm ferrite, vuam tsis xws li porosity thiab slag inclusions tshwm sim tsawg zaus.

 

 

 

Susceptibility rau Hydrogen - Induced Cracking
Kub - dov steel daim hlau nrog cov feem ntau ntawm ferrite muaj ib tug kuj tsis tshua muaj susceptibility rau hydrogen - induced cracking. Thaum lub sij hawm vuam txheej txheem, hydrogen atoms yooj yim yaj nyob rau hauv cov hlau lattice. Thaum cov weld txias, hydrogen atoms sib sau ua ke ntawm cov lattice defects los tsim hydrogen gas, ua rau tawg tsim. Txawm li cas los xij, nyob rau hauv cov hlau daim hlau uas muaj feem ntau ntawm ferrite, vim yog cov qauv siv lead ua yooj yim ntawm ferrite, qhov diffusion tus nqi ntawm hydrogen atoms nyob rau hauv nws yog ceev ceev, thiab nws tsis yooj yim rau lawv kom sib sau ua ib tug siab concentration ntawm hydrogen, yog li txo qhov susceptibility rau hydrogen - induced cracking.
