N'chifukwa chiyani zitsulo za carbon dioxide zimakhala zovuta kuwotcherera?

Chitsulo cha Carbon Chokwera sichimawotcherera bwino chifukwa chokhala ndi mpweya wambiri.The kuwotcherera mbali ndi motere:
(1) kusayenda bwino kwa matenthedwe, kusiyana kwakukulu kwa kutentha pakati pa chigawo cha weld ndi gawo losatenthedwa.Dziwe losungunuka likazizira kwambiri, kupsinjika kwamkati mu weld kumatha kupanga ming'alu mosavuta.
(2) imakhala yovuta kwambiri kuzimitsa ndipo martensite imapangidwa mosavuta pafupi ndi msoko.Chifukwa cha kupsinjika kwa kapangidwe kake, malo oyandikira msoko amatulutsa mng'alu wozizira.
(3) chifukwa cha kutentha kwakukulu, njere zimakula mofulumira, carbide ndi yosavuta kudziunjikira ndikukula pa malire a tirigu, zomwe zimapangitsa weld kukhala wofooka ndipo mphamvu ya kuwotcherera imachepa.
(4) mkulu mpweya zitsulo ndi zambiri kutulutsa ming'alu otentha kuposa sing'anga mpweya zitsulo
Mkulu wa carbon zitsulo ndi mtundu wa carbon zitsulo ndi w (c)> 0,6%.Amakhala ndi chizoloŵezi choumitsa ndi kupanga carbon martensite yapamwamba kuposa zitsulo zamkati za carbon, ndipo zimakhala zovuta kwambiri pakupanga ming'alu yozizira.

Panthawi imodzimodziyo, mapangidwe a martensite omwe amapangidwa mu HAZ ali ndi zinthu zolimba komanso zowonongeka, zomwe zimabweretsa kuchepa kwa pulasitiki ndi kulimba kwa mgwirizano.Choncho, weldability wa mkulu mpweya zitsulo m'malo osauka, ndi ndondomeko kuwotcherera wapadera ayenera anatengera, kuonetsetsa ntchito cholumikizira.
Choncho, mu kuwotcherera dongosolo, kawirikawiri ntchito.Chitsulo chachikulu cha kaboni chimagwiritsidwa ntchito makamaka pamakina omwe amafunikira kulimba kwambiri komanso kukana kuvala, monga ma rotary shafts, magiya akulu ndi ma couplings.
Pofuna kupulumutsa zitsulo ndi kuphweka ukadaulo wokonza, magawo amakinawa nthawi zambiri amapangidwa ndi ma welded.Popanga makina olemera, mbali zambiri zazitsulo za carbon zidzakumananso ndi zovuta zowotcherera.
Pamene kupanga kuwotcherera mbali mkulu mpweya zitsulo, m`pofunika kusanthula mitundu yonse ya zofooka zotheka kuwotcherera ndi kutenga lolingana kuwotcherera ndondomeko miyeso.
