Emikhiqizweni ehlanganisiwe ye-carbide enosimende, ukushisela kuyindlela yokucubungula evame ukusetshenziswa, kodwa ngokuvamile ukunganaki okuncane, kulula ukukhiqiza imifantu yokushisela, okubangela ukuthi umkhiqizo ulahlwe, futhi konke ukucubungula kwangaphambili kuzokwehla.Ngakho-ke, kubaluleke kakhulu ukuqonda izimbangela zokuqhekeka kwe-cemented carbide welding nokugwema imifantu yokushisela.Namuhla, umhleli weChuangrui Technology uzokhuluma nawe ngezizathu zokuqhekeka kwe-carbide welding, futhi akunikeze ireferensi.
Ku-welding, izinto ezihlukene zizoba nezici ezihlukene ze-welding.Ngokwazi kuphela uhlobo lwezinto ezizofakwa ezishiselwe lapho singakwazi ukwenza kahle uhlelo lokwakha i-welding, ukuze sikhethe indinganiso yenqubo efanele yokuqinisekisa ikhwalithi yokushisela.Izizathu zokuqhekeka kwe-cemented carbide welding zihlaziywa ikakhulukazi kusuka kulezi zici ezilandelayo.
Okokuqala, kunqunywa izici ze-carbide esimende i-Cai Laoda.Njengoba sonke sazi, ubulukhuni bensimbi yesisekelo sokushisela buncike ku-carbon element entweni.Ngokukhula kokuqukethwe kwekhabhoni, ubulukhuni buzokhula ngokufanele, futhi vele ukuthambekela kokuqhekeka okukhiqizwa ngesikhathi sokushisela nakho kuzokwanda.Ngakho-ke, ukushisela i-carbide enosimende kujwayele ukuqhekeka.
Okwesibili, lapho i-carbide enosimende ishiselwe, uma iqhathaniswa nensimbi ephansi ye-carbon, indawo yayo ethintekayo ekushiseleni ukushisa ijwayele ukwakheka okuqinile, okuzwela kakhulu ku-hydrogen element ekushiseleni, futhi ijoyinti elihlanganisiwe le-carbide enosimende lingamelana nokukhulu Ngaphansi kokucindezeleka, okuhlukahlukene. imifantu ijwayele ukwenzeka.Ngaphansi komjikelezo wokushisa we-welding, i-microstructure kanye nezakhiwo zokushisa ezithintekile zone ushintsho lwe-weld, ngaleyo ndlela kukhulisa ukuthambekela kokukhiqizwa kwe-crack.
Okwesithathu, i-embrittlement yesakhiwo esishiswe ngokweqile endaweni ethintekile yokushisa ye-welded joint kuholela ekuveleni kwemifantu ye-welding.Lokhu ikakhulukazi kuncike ekubunjweni kwezinkuni ze-carbide ezinosimende kanye nomjikelezo wokushisa we-welding, okuzothinteka isikhathi sokuhlala sokushisa okuphezulu kanye nezinga lokupholisa lechibi elincibilikisiwe ngesikhathi sokushisela.
Lokhu okungenhla yizizathu ezimbalwa zokuthi kungani ukushisela kwe-carbide okusikiwe kuzodala imifantu.Ngokufakwa kwe-welding yezinto ezinjalo, kuyadingeka ukuhlanganisa izici ze-welding zezinto zokwakha ukuze ukhethe kahle izinto zokushisela, wenze amalungiselelo ngaphambi nangemva kwe-welding, uhambisane ngokuqinile nezindinganiso zenqubo, futhi uqinise inqubo yokushisela.Ukushisa, ukugcinwa kokushisa kwe-post-weld kanye nokwelashwa kokushisa kuyadingeka ukuze kuvinjelwe ukuvela kwemifantu yokushisela i-carbide ene-cemented.
I-carbide enosimende inzima kakhulu futhi i-brittle.Ukunganaki okuncane ohlelweni lokushisela kuzoholela ekukhishweni ngenxa yokuqhekeka.Ngakho-ke, kufanele senze amalungiselelo aphelele lapho sishisela i-carbide enosimende.Amazinga okucubungula ukugwema imifantu yokushisela.
