I-Medium carbon steel ngokuvamile ibhekisela kokuqukethwe kwekhabhoni okungaba ngu-0.25 kuya ku-0.60% we-carbon steel.I-arc welding manual ye-carbon steel casting kanye ne-welding yezici eziyinhloko kanje:
(1) Isisekelo sensimbi eduze nendawo yokushisela ethambekele ekubeni nepulasitiki ephansi yezicubu eziqinile.Ukuphakama kokuqukethwe kwekhabhoni, ukushuba kwepuleti, kulapho ukuthambekela kuba lukhuni.I-Weldment stiffer, ukupholisa okusheshayo nokukhethwa kwezinduku akusona isikhathi, esijwayele ukuqhekeka okubandayo.
(2) Njengoba isisekelo sensimbi sancibilika saba ungqimba lokuqala lwe-weld metal isilinganiso esingaba ngu-30%, ngakho ukuphakama kwekhabhoni ye-weld, umphumela kuba lula ukushisela ukuqhekeka okushisayo kwensimbi nokuqhekeka okubandayo.
Izinyathelo ezithathwe ukushiselwa kwe-carbon steel
(1) Uma kungenzeka, khetha ama-electrode ayisisekelo ane-hydrogen.Ama-electrode anjalo nokumelana okuphezulu kokumelana nokuqhekeka okubandayo kumthamo wokuqhekeka oshisayo.Amacala ngamanye, ngokulawula ngokuqinile izinga lokushisa langaphambi kokushisa nokunciphisa ukuncishiswa kwesisekelo sensimbi ukungena kwe-weld okuqukethwe kwekhabhoni nezinye izinyathelo zenqubo, ukusetshenziswa kwe-electrode yohlobo lwe-calcium ilmenite kungase futhi kuthole imiphumela egculisayo.Lapho amandla ahlangene ashiselwe kanye nesisekelo sensimbi akudingi isikhathi esilinganayo kufanele kusetshenziswe ku-low-intensity eyisisekelo ephansi ye-hydrogen electrode.Ipulasitiki ye-Weld Weld enjalo, ikhiqiza ukuqhekeka okubandayo kanye nokuqhekeka okushisayo okuyingozi kakhulu.
(2) Shisisa izinyathelo zobuchwepheshe eziyinhloko zokushisela nokulungisa ukushisela kwe-carbon steel, ikakhulukazi ukushuba kwe-weldment, ukuqina kukhulu, ukufudumala ukuze kuncishiswe ubulukhuni obukhulu bendawo ethintekile ukushisa futhi kuvimbele ukuqhekeka okubandayo, futhi kungathuthuka. ipulasitiki ehlangene.Ukufudumala sekukonke kanye nokufudumala okufanele nakho kunciphisa ingcindezi yendawo ye-post weld residual.Okuqukethwe kwekhabhoni ye-welding ehlukene ye-carbon steel welding lokushisa lokushisa ngaphambi kokushisa futhi akukho mithetho efanayo.Lokhu akukona nje kuphela ngenxa yokuthi ukukhethwa kokushisa kwangaphambi kokushisa kunqunywa okuqukethwe kwekhabhoni ye-electrode, kodwa futhi kuthinteka ezinye izici, njengobukhulu nobukhulu be-weldment, uhlobo lwe-welding, imingcele yokushisela kanye nokuqina kwesakhiwo kanye njalonjalo.
