Ngenxa yokuqina okuphezulu nokuqina kwama-alloys aqinile, akulula ukushisela njengezinye izinto.I-Zhuzhou Chuangrui Cemented Carbide Co., Ltd. ikuhlelele izindlela zokushisela ze-carbide enosimende, ngethemba ukuthi ingakusiza.
Ngenxa yomehluko omkhulu emisebenzini engokwenyama phakathi kwe-tungsten carbide ne-carbon steel, i-brazing ne-disperse welding kuseyizindlela zokushisela ezinokwenzeka futhi eziwusizo.Ngaphezu kwalokho, ezinye izindlela zokushisela ezintsha ezifana ne-tungsten electrode inert gas maintenance arc welding (TIG), i-electron beam welding (EB-W), i-laser welding (LBW), njll. nazo ziyaxoxwa futhi zihlolwe ngenkuthalo, ezingasetshenziswa ukushisela carbide ngosimende esikhathini esizayo.
I-Brazing brazing iyindlela yendabuko futhi esetshenziswa kabanzi ye-carbide welding.Ezindleleni ze-brazing ze-carbide ene-cemented nensimbi, ngokusho kwendlela yokushisa, kukhona ukuvutha komlilo wegesi, ukushisa kwesithando somlilo, i-vacuum brazing, i-induction brazing, i-resistance brazing kanye namakhono e-laser brazing.Kungakhathaliseki ukuthi yikuphi, indawo yokuncibilika yensimbi yokubopha iphansi kunesisekelo sensimbi futhi isakazwa ngokuhlanganyela ngokukhanga kwe-capillary.Imikhiqizo exhunyiwe ihlanganisa izingcezu zokubhoboza imithombo kawoyela, izitembu ezishisayo nezibandayo, isikhunta se-powder metallurgy, amaroli, amathuluzi okusika namathuluzi okulinganisa, amathuluzi okumba amatshe, amathuluzi okusebenza ngokhuni, njll.
Insimbi ye-Brazing iyinto yokugcwalisa esetshenziselwa ukubhoboza, edlala indima ebalulekile emsebenzini wokuhlanganisa.Umsebenzi we-Solder ungenye yezinto ezibalulekile ezinquma ikhwalithi ye-brazing.
Imishini yokushisa ilangabi legesi ilula, ingashiswa futhi ishiselwe ngamalangabi amaningi ngokuya ngokuma kwendawo yokusebenza.Insimbi yokufaka insimbi ngokuvamile yenziwe nge-filamentous noma i-flake esekelwe ngethusi kanye ne-silver-based brazing filler metal, elungele ucezu olulodwa nokukhiqizwa kwe-batch encane, kodwa ukukhethwa kwethoshi lokushisela igesi nokwelashwa kokushisa ngemva kokubhula nezinye izinto ezingaqinisekile kungaphezulu. , futhi ikhwalithi nokuthembeka kwe-brazing kuncane.
Isivuno se-tungsten carbide cutters ye-induction brazing, ukumelana ne-brazing kanye ne-brazing esithandweni siphezulu, futhi ikhwalithi izinzile, kodwa imishini namakhono kungcolile kakhulu, isikali nokuma kwe-workpiece kuyadingeka ukuba kuphakame, futhi i-vacuum brazing ingafinyelela izinga eliphezulu lokubhula, kodwa okokusebenza kuyabiza futhi namakhono anzima
Njengohlobo olusha lomthombo wokushisa we-welding, i-laser inezici zesivinini sokushisa okusheshayo, indawo encane ethintekile ukushisa, ukuguqulwa kwe-post-welding kanye nokucindezeleka okuncane okusalayo, ikakhulukazi ekwenzeni buthaka ukuvuthwa kwendawo yokuhlanganisa ehlangene, enezinzuzo ezivamile, okwenza ibuye isetshenziswe ekushiseleni i-carbide enosimende.Ngakho-ke, lapho ukhetha indlela ye-welding, kufanele ifaneleke ngokuyinhloko, futhi ngokuvamile ukugqama esithandweni kunganelisa isicelo sokubhinca ithuluzi.
(1)Ukushisela okuhlakaziwe
I-vacuum dispersion welding kanye ne-HIP dispersion welding ingasetshenziswa ekushiseleni kwe-carbide enosimende.Ku-vacuum dispersion welding, kunezici eziningi ezithinta ikhwalithi yejoyinti, njengokwakheka kwento, ikhwalithi yendawo eshiselwe, idigri ye-vacuum, idatha yesemishi elimaphakathi, nezinga lokushisa nokupholisa, kodwa izici ezibaluleke kakhulu izinga lokushisa, ingcindezi kanye nesikhathi.Amandla we-shear we-weld ngokuvamile athuthuka ngokungezwa kwesikhathi sokushisela, ngoba ukwandiswa kwesikhathi sokushisela kungenza iningi lama-micro-bumps endaweni eshiselwe anyamalale, indawo yokuthinta ingeziwe ngokusobala, ukuhlakazeka kwama-athomu kungaphezulu. luningi, futhi izinga lokushisela lingathuthukiswa kakhulu
(2)I-tungsten inert ye-inert ye-arc welding yegesi
Ukushisela kwe-TIG, njengendlela entsha yokuhlanganisa i-carbide nensimbi, kusesikhathini sokuhlolwa.
(3)Ukushisela i-electron beam
I-Electron beam welding inezinzuzo zokuminyana kwamandla okushisa aphezulu, ukuwohloka okuncane ngemuva kokushisela, isilinganiso esikhulu sobubanzi bobubanzi be-weld, nokulungiswa okubanzi kwamapharamitha ajwayelekile, futhi ngenxa yokuthi inqubo yokushisa yokushisela imfushane kakhulu, ingase ibe indlela entsha yokushisela. i-carbide enosimende ngokulawula ukuhlakazwa kwezakhi ngokwezinga elithile.
