1. gulu
Malingana ndi kuchuluka kwa carbon, carbon steel ikhoza kugawidwa m'magulu atatu awa:
1) Chitsulo chochepa cha carbon C% ≤ 0.25
2) Sing'anga mpweya zitsulo 0.25
3) Mkulu wa carbon zitsulo C%> 0,6
Low Carton
Pakati pa Carbon
High-Carbon
2. weldability kusanthula
Kuchuluka kwa mpweya wa kaboni ndilofunika kwambiri pakupanga njira zowotcherera. Pamene mpweya wa carbon ukuwonjezeka, mphamvu ndi kuuma kumawonjezeka, pamene pulasitiki ndi kulimba kumachepa, pamene kupanikizika kumawonjezeka. Kunena zoona, kutsika kwa mpweya wa carbon, kumapangitsanso kuwotcherera kwabwino, kotero, zomwe zili mu kaboni ndizomwe zimayesa zovuta za kuwotcherera kwa carbon zitsulo, ndipo njira zosiyanasiyana zowotcherera ziyenera kutengedwa pazinthu zosiyanasiyana za carbon.
3. Njira yowotcherera
Kusankhidwa kwa zida zowotcherera zitsulo za kaboni kumatsatira mfundo ya "mphamvu yofanana"
1. Chitsulo chochepa cha carbon (chomwe chimatchedwa chitsulo chochepa)
Magiredi wamba achitsulo monga Q235 (omwe amadziwika kuti A3 zitsulo), Q255, ndi zina zotero, nthawi zambiri samatengera njira zapadera powotcherera, ngakhale kutentha kapena kutenthedwa.
2. Sing'anga mpweya zitsulo
Ambiri ntchito zitsulo monga 30 #, 45 #, etc., 45 # ndi zinthu zopangira macheka masamba ndi owona, ndi bwino ntchito otsika-hydrogen kuwotcherera zipangizo ndi kukana wabwino mng'alu, preheating 100-200 °C; Ngati sikoyenera kutenthetsa, Cr-Ni austenitic zitsulo zosapanga dzimbiri zitha kusankhidwa.
3. Zitsulo zapamwamba za carbon
Ambiri ntchito zitsulo sukulu monga 60Si2Mn, T8, T10 ndi zina zotero. 60Si2Mn ndi mmene kasupe zitsulo, ambiri sachita kuwotcherera mankhwala, makamaka ntchito ngati kachiwiri kuwotcherera, ayenera kukhala 250-350 °C preheating, kuwotcherera ayenera nyundo kuthetsa nkhawa, ndi 650 °C pambuyo kutentha mankhwala, angathenso. kusankha Cr-Ni austenitic zosapanga dzimbiri kuwotcherera zipangizo
Chachinayi, wofatsa zitsulo dzanja elekitirodi General kuwotcherera zofunika:
Electrode kuyanika kutentha
| Kanthu | Mtundu wa khungu | Zogulitsa | Kutentha | Nthawi |
| Chitsulo chochepa cha carbon ndi chitsulo champhamvu kwambiri | Mtundu wa haidrojeni wotsika | E7016, E7048, E7015, E7015-G | 300-350 ℃ | 60 min |
| E7015, E8015-G, E9016-G, E9015-D1, E10015-D2, E12015-G | 330-380 ℃ | |||
| High toughness ndi otsika mtundu wa haidrojeni | E7016-G, E7015-G, E8015-G, E9015-G, E10015-G | 350-380 ℃ | 60 min | |
| Iron ufa otsika mtundu wa haidrojeni | E7018, E7018-1 | 300-350 ℃ | 60 min | |
| E8018-G,E918-G,E9018-M,E10018-D2,E10018M,E11018-G,E11018M,E12018-G | 350-380 ℃ | 60 min |
2. Chinyezi, mafuta, dzimbiri, ndi zina zotero pamwamba pa zinthu zapansi ziyenera kuchotsedwa
3. Gwiritsani ntchito njira yobwerera m'mbuyo powotcherera popewa stomata poyambira
Short arc kuwotcherera ayenera kugwiritsidwa ntchito, monga oscillating n'kupanga, ndi oscillation matalikidwe sayenera upambana 3 kuwirikiza waya awiri.
