Ama-alloys e-Titanium ane-low density, amandla athile aphezulu, ukumelana nokugqwala okuhle, ukuguquguquka okuphansi kwe-thermal, okungewona ubuthi futhi okungezona uzibuthe, futhi kungenziwa ashiselwe; asetshenziswa kabanzi kwezokundiza, indiza, amakhemikhali, uphethiloli, ugesi, ezokwelapha, ezokwakha, ezemidlalo kanye neminye imikhakha.
Izindlela zokushisela ezijwayelekile ze-titanium ne-titanium alloys zifaka: i-argon arc welding, i-arc welding engaphansi, i-vacuum electron beam welding, njll.
Ukulungiselela ngaphambi kokushisela
Izinga eliphezulu le-weldment kanye ne-titanium welding wire linethonya elikhulu ezintweni zemishini yejoyinti elihlanganisiwe, ngakho-ke kufanele lihlanzwe ngokuqinile.
1) Ukuhlanzwa ngomshini: Kumashisela angadingi izinga eliphezulu lokushisela noma okunzima ukuwacolisa, i-sandpaper ecolekile noma amabhulashi ensimbi engagqwali angasetshenziswa ukuwasula, kodwa kungcono kakhulu ukusebenzisa i-carbide yellow ukuklwebha ipuleti le-titanium ukususa ifilimu ye-oxide.
2) Ukuhlanza amakhemikhali: Ngaphambi kokushisela, ucezu lokuhlola kanye nocingo lokushisela lungafakwa emanzini. Isixazululo se-pickling singaba i-HF (5%) + i-HNO3 (35%) isixazululo samanzi. Hlanza ngamanzi ahlanzekile ngemva kokukhetha, futhi weld ngokushesha ngemva kokumisa. Noma sebenzisa i-acetone, i-ethanol, i-carbon tetrachloride, i-methanol, njll. ukuze usule umsele we-titanium plate nezinhlangothi zombili (ngaphakathi kuka-50mm lilinye), ingaphezulu lentambo yokushisela, kanye nengxenye lapho isigxivizo sithintana nepuleti le-titanium.
3) Ukukhethwa kwemishini yokushisela: Ku-argon arc welding ye-titanium ne-titanium alloy tungsten amapuleti, umthombo wamandla wokushisela we-DC argon arc onezici zangaphandle kanye nokuqaliswa kwe-arc ye-high-frequency arc kufanele kukhethwe, futhi isikhathi esibambezelekile sokulethwa kwegesi akufanele sibe ngaphansi Imizuzwana engu-15 ukugwema i-oxidation kanye nokungcoliswa kwe-weldment.
4) Ukukhethwa kwezinto zokushisela: Ukuhlanzeka kwegesi ye-argon akufanele kube ngaphansi kuka-99.99%, indawo yamazolo kufanele ibe ngaphansi -40 ℃, futhi ingxenye enkulu yokungcola kufanele ibe ngu-0.001%. Lapho ukucindezela kusilinda se-argon kwehla ku-0.981MPa, kufanele kumiswe ukuze kuvinjelwe ukuphazamisa ikhwalithi yejoyinti elishiselwe.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)
5) Ukuvikelwa kwegesi kanye nezinga lokushisa lokushisela: Ipayipi le-titanium elihlangene liphansi ngesikhathi sokushisela. Ukuze kuvinjwe ijoyinti elishiselwe ukuthi lingangcoliswa amagesi ayingozi kanye nezakhi emazingeni okushisa aphezulu, indawo yokushisela kanye ne-weld kufanele ibhekane nokuvikelwa okudingekayo kokushisela nokulawulwa kwezinga lokushisa, futhi izinga lokushisa kufanele libe ngaphansi kuka-250℃.
Imiyalelo yokusebenza
1. Uma wenza i-argon arc welding manual, i-engeli encane (10~15 °) kufanele igcinwe phakathi kwentambo yokushisela kanye nokushisela. Intambo yokushisela kufanele ifakwe echibini elincibilikisiwe kancane kancane futhi ngokulinganayo ngasekugcineni okungaphambili kwechibi elincibilikisiwe, futhi isiphetho sentambo yokushisela akufanele isuswe endaweni yokuvikela i-argon.
2. Lapho sishisela, isibhamu esishiselayo asijiki sivundlile. Uma idinga ukushwiba, imvamisa kufanele ibe phansi futhi i-swing amplitude akufanele ibe nkulu kakhulu ukuvimbela ukuthinta ukuvikelwa kwegesi ye-argon.
3. Lapho uphula i-arc futhi uqeda ukushisela, qhubeka udlulisa ukuvikelwa kwe-argon kuze kube yilapho ukushisela nensimbi endaweni ethinteke ukushisa kuphole kuze kube ngaphansi kuka-350℃ ngaphambi kokukhipha isibhamu sokushisela.
Umbala ongaphezulu wendawo yokushisela nendawo ethinteke ukushisa
1. Indawo yokushisela
Isiliva elimhlophe, eliphuzi elikhanyayo (elivunyelwe ukushisela ezingeni lokuqala, lesibili nelesithathu); okuphuzi okumnyama (kuvunyelwe ukushisela ezingeni lesibili nelesithathu); onsomi begolide (okuvunyelwe ukushisela ezingeni lesithathu); okuluhlaza okwesibhakabhaka okumnyama (okungavunyelwe ezingeni lokuqala, lesibili nelesithathu).
2. Indawo ethinteke ukushisa
Isiliva elimhlophe, eliphuzi elikhanyayo (elivunyelwe ukushisela ezingeni lokuqala, lesibili nelesithathu); okuphuzi okumnyama, okunsomi kwegolide (kuvunyelwe ukushisela ezingeni lesibili nelesithathu); okuluhlaza okwesibhakabhaka okumnyama (okuvunyelwe ukushisela ezingeni lesithathu).
