Ngenxa ye-insimbi ephansi ye-carboninokuqukethwe kwekhabhoni ephansi, i-manganese, okuqukethwe kwe-silicon nakho kuncane, ngakho-ke, ngaphansi kwezimo ezijwayelekile ngeke kufakwe i-welded ukukhiqiza izicubu ezinzima eziqinile noma isakhiwo esicishiwe.Low carbon steel welding joints plasticity kanye nomthelela ukuqina okuhle, welding, futhi ngokuvamile akudingi preheating control ungqimba lokushisa futhi ngemva kushisa, abanayo post-weld ukwelashwa ukushisa ukuthuthukisa inhlangano futhi yonke inqubo Welding akudingeki ukuthatha ekhethekile. izinyathelo kule nqubo, weldability omuhle kakhulu.

Kodwa-ke, ezimweni ezimbalwa, ukushisela kubuye kube nobunzima:
(1) Ukukhiqizwa kwensimbi yokuguqula indlela endala yokuncibilikisa enokuqukethwe okuphezulu kwe-nitrogen, okuqukethwe okungcolile, ukuqina okubandayo, ukuzwela okukhulayo ekugugeni, kunciphisa ikhwalithi yamalunga ashiselwe, ukushisela ukuwohloka.
(2) i-deoxidation yensimbi ebilayo ayiphelele okuqukethwe komoyampilo okuphezulu, ukungcola kwe-P okufana nokusatshalaliswa okungalingani kokuqukethwe kwendawo kuzokweqiwa, ukuzwela ukuguga kanye nokuzwela okubanda okubanda kokuthambekela kokuqhekeka okushisayo kuyanda.
(3) Ikhwalithi ayihlangabezani nezidingo zama-electrode, ukuze i-carbon ensimbi ye-weld, okuqukethwe kwesibabule kuphezulu kakhulu, kungabangela ukuqhekeka.I-Q235-Insimbi ene-asidi yensimbi yokushisela i-electrode, njengemboni, ngenxa ye-electrode emboza okuqukethwe kwekhabhoni ephezulu ye-ferromanganese, izodala ukuqhekeka okushisayo kwe-weld.
(4) Enye indlela yokushisela izonciphisa ikhwalithi yamalunga ashiselwe ensimbi enekhabhoni ephansi.Okufana ne-electroslag welding line energy, yenza isifunda esimahhadlavuza sendawo ethintekile okusanhlamvu sibukeke siyinkulu kakhulu kubangele ukwehla okukhulu kokuqina komthelela ngemva kokushisela kufanele kwenziwe ukucolisiswa okusanhlamvu okujwayelekile ukuze kuthuthukiswe ukuqina komthelela.

Ngamafuphi, insimbi enekhabhoni ephansi inokushisela okungcono kakhulu futhi ishiselwe kalula, zonke izindlela zokushisela zisetshenziswa ekushiseleleni insimbi enekhabhoni ephansi.
