Chifukwa chachitsulo chochepa cha carbonali ndi otsika mpweya okhutira, manganese, pakachitsulo zilinso yaing'ono, choncho, muzochitika bwinobwino sadzakhala welded kupanga kwambiri kuumitsa minofu kapena kuzimitsidwa dongosolo.Low mpweya zitsulo kuwotcherera mfundo plasticity ndi zotsatira zabwino toughness, kuwotcherera, ndipo sikutanthauza preheating ulamuliro wosanjikiza kutentha ndi pambuyo otentha, alibe pambuyo kuwotcherera kutentha mankhwala kusintha gulu ndi ndondomeko kuwotcherera alibe kutenga wapadera. miyeso mu ndondomeko, weldability kwambiri.

Komabe, nthawi zina kuwotcherera kumakhalanso kovuta:
(1) Kupanga chitsulo chosinthira njira yakale yosungunula yokhala ndi nayitrogeni wambiri, zonyansa, kuzizira kozizira, kukhudzika kwa ukalamba, kuchepetsa kulumikizana kwa welded, kuwotcherera kumawonongeka.
(2) chitsulo chowotcha chitsulo deoxidation chosakwanira kukwanira kwa okosijeni, zonyansa za P monga kugawa kosagwirizana kwa zomwe zili mdera lanu zidzapitilira, kukhudzika kwa ukalamba ndi kuzizira kwamphamvu kwa kutentha kwamphamvu kumawonjezeka.
(3) Khalidwe silimakwaniritsa zofunikira za ma electrode, kotero kuti mpweya muzitsulo zowotcherera, sulfure ndi yochuluka kwambiri, ingayambitse ming'alu.Q235-Chitsulo chachitsulo chowotcherera ma elekitirodi, monga fakitale, chifukwa cha ma elekitirodi omwe amaphimba mpweya wambiri wa ferromanganese, amachititsa kuti weld awonongeke.
(4) Njira ina yowotcherera imachepetsa ubwino wazitsulo zowotcherera zachitsulo chochepa cha carbon.Monga electroslag kuwotcherera mzere mphamvu, kupanga coarse grained dera lakhudzidwa ndi kutentha njere kuwoneka wochulukirachulukira anachititsa kutsika kwambiri kulimba amakhudzidwa pambuyo kuwotcherera ayenera wachibadwa kuyenga tirigu kuti kulimbitsa mphamvu.

Mwachidule, chitsulo chochepa cha carbon ndi chowotcherera bwino kwambiri komanso chosavuta kwambiri, njira zonse zowotcherera zimagwiritsidwa ntchito pazitsulo zotsika kwambiri za carbon.
