High Carbon Steel muaj qhov tsis zoo weldability vim nws cov ntsiab lus carbon siab.Cov yam ntxwv ntawm welding yog raws li nram no:
(1) thermal conductivity tsis zoo, qhov kub thiab txias sib txawv ntawm thaj chaw weld thiab qhov tsis muaj cua sov.Thaum lub pas dej molten txias txias, qhov kev ntxhov siab sab hauv hauv qhov vuam tuaj yeem yooj yim tsim cov kab nrib pleb.
(2) nws yog rhiab heev rau quenching thiab martensite yog yooj yim tsim nyob rau hauv ze-seam cheeb tsam.Vim yog qhov kev txiav txim ntawm cov qauv kev ntxhov siab, thaj tsam ze-seam ua rau qhov txias tawg.
(3) vim yog qhov kub thiab txias, cov nplej loj hlob sai, cov carbide yog ib qho yooj yim mus sau thiab loj hlob ntawm cov qoob loo ciam teb, uas ua rau cov weld tsis muaj zog thiab lub zog ntawm vuam sib koom ua ke txo.
(4) cov pa roj carbon ntau yuav ua rau kub tawg dua li cov pa roj carbon nruab nrab
High carbon steel yog ib hom carbon steel nrog w (c) > 0.6%.Nws muaj lub siab xav ua kom tawv thiab tsim cov pa roj carbon martensite siab dua li cov pa roj carbon nruab nrab, thiab muaj kev nkag siab ntau dua rau kev tsim cov kab mob khaub thuas.
Nyob rau tib lub sijhawm, cov qauv martensite tsim nyob rau hauv HAZ muaj zog thiab nkig zog, uas ua rau txo qis ntawm plasticity thiab toughness ntawm qhov sib koom ua ke.Yog li ntawd, lub weldability ntawm high carbon steel yog tsis zoo, thiab tshwj xeeb vuam txheej txheem yuav tsum tau saws, los xyuas kom meej qhov kev ua tau zoo ntawm lub connector.
Yog li ntawd, nyob rau hauv lub vuam qauv, feem ntau tsis tshua siv.Cov pa roj carbon ntau yog siv rau cov khoom siv tshuab uas xav tau kev ua haujlwm siab thiab hnav tsis kam, xws li cov rotary shafts, lub zog loj thiab cov couplings.
Yuav kom txuag tau cov hlau thiab ua kom yooj yim rau kev siv tshuab, cov tshuab no feem ntau yog ua los ntawm cov qauv welded.Hauv kev tsim cov tshuab hnyav, cov pa roj carbon steel siab kuj yuav ntsib teeb meem vuam.
Thaum ua cov txheej txheem welding ntawm siab carbon steel qhov chaw, nws yog ib qho tsim nyog los tshuaj xyuas txhua yam ntawm qhov ua tau vuam tsis xws luag thiab coj cov txheej txheem vuam sib txuas.
