Titanium: titanium Welding (technology). Titanium Welding argon

Ngo zezindiza, shipbuilding, imishini, futhi kwamanye izimboni womshini ISIZINDA eziyinkimbinkimbi futhi kuyakhandla usebenzisa izinto ezibizayo ezifana titanium. Kuyinto enhle hhayi kuphela isisindo sayo ongaphakeme, kodwa futhi iqiniso lokuthi metal lungekho ukugqwala izinqubo. Ake sihlolisise lokho ngempela titanium. titanium Welding - sekuyinto i sihloko ezithakazelisayo ukukhuluma ngalokhu futhi kuzoxoxwa.

Nasi ulwazi olujwayelekile

Vele uthathe bese usebenzisa ucezu titanium etholwe ezingavamile. Ngokuvamile it is pretreated. Kuyaqondakala ukuthi ngokuvamile ibizwa ngaphansi Welding. Kodwa kusukela ngo-metal asebenzayo libhekisela Ezingalapheki, izazi bebhekene nenkinga nolokubhujiswa okokusebenza lokushisa 400 Celsius ngaphansi kwethonya amanzi umusi, umoya-mpilo, futhi i-nitrogen. Ngu uqobo, le nqubo ngempela eziyinkimbinkimbi, njengoba kubalulekile ukuba athobele inqwaba iziqondiso lobuchwepheshe, futhi yiluphi uhlobo zokushisela kufanelekile ngokucubungula metal. Kunoma ikuphi, namuhla wafunda ukucubungula titanium. titanium Welding Kwenziwa izindlela eziningana:

• electron ugongolo;
• arc ecucuza;
• argon.

Okwamanje adumile zonke izindlela, kodwa argon obanzi kunayo Welding ngenxa yezizathu eziningana, iphuzu esizoxoxa ngalo kamuva.

Titanium futhi Alloys yayo

metal Active kwasakazwa imvelo ngokwanele. Abaningi bathi akwanele, kodwa ngifuna ukuqhathanisa. Kunoma ikuphi, inani titanium e koqweqwe mkhulu kunezinhliziyo ithusi noma phambili. Lena metal okuhlala kakhulu. Ngesimo okumsulwa sifinyelela ngamandla 337 MPA, futhi ingxubevange oda 1 kuya 250 MPA. I ukuma titanium - 1668 degrees Celsius.

Emazingeni evamile, ukumelana ukugqwala futhi isebenza ezindaweni nobutha. Nokho, uma izinga lokushisa ifinyelela degrees 400 Celsius ukushayela izici ukwehla. It ihlangana ngamandla ne-nitrogen kuqala ukuba oxidized ngu-oksijini, umhwamuko, okuyinto kanzima kukhawula nobukhulu bayo. Kuyaphawuleka ukuthi ezibonakalayo abanakho ukuthambekela kwemifantu esishisayo ngesikhathi Welding, kodwa uhlamvu yayo iba ezinkudlwana, ezehlisa izici lobuchwepheshe insimbi izinga weld. Ngomqondo onabile, siyaqonda kancane okungukuthi titanium. titanium Welding - nakhu okunye ezithakazelisayo. Sazise futhi sizobe ukukhuluma.

izici kwezobuchwepheshe Welding

Ngaleso sikhathi samanje, hhayi singasho ukuthi titanium siyindlala lokhu noma ukuthi umkhiqizo. Kwasebenza naye eziningi abakhiqizi kusukela zimboni. Kodwa kumelwe siwaqonde ngokuthi titanium - esebenzayo chemical isici. Lokhu kusikisela ukuthi ukusetshenziswa Welding ezivamile kungamukeleki. Isizathu siwukuthi ngesikhathi sokuwa ukungcola ngesimo carbides futhi nitrides okuyinto ukunciphisa ukusebenza komsebenzi.

Ngakho-ke, isimo esiyisisekelo sokuba Welding - bahlukaniswe ngokuphelele kusukela ezungezile. Lawa:-mpilo, i-nitrogen, hydrogen nabanye. Ngaphezu kwalokho, umsebenzi Welding kumele kwenziwe ngesivinini kuqhathaniswa eliphezulu. Ukushisa isikhathi eside e eheleni crystal yandisa okusanhlamvu kuyo, kona kakhulu kwandisa brittleness. Kunoma ikuphi, Welding titanium, okuzoxoxwa kabanzi ngezansi ubuchwepheshe - inqubo eyinkimbinkimbi futhi eziyinselele. Futhi manje ake udlulela phambili.

Titanium Welding argon

Argon uhlobo Welding lokhu metal kuyinto ethandwa kakhulu phakathi ochwepheshe emhlabeni wonke. Lokhu kungenxa yokuthi alisetshenziswa khona fluxes kanye electrode Ngakho kwenziwa ezicashile nolunzima Welding imisebenzi. Ngaphezu kwalokho, indlela yokuthola argon welds iphathelene izinhlobo eliphezulu zokushisela. Nge ubuchwepheshe eliphezulu uphawu is eyatholakala.

Asinakusho mayelana jikelele koHlelo argon Welding. Ihlala eqinisweni lokuthi kukhona nekhono lokusingatha kokubili izakhiwo ezinkulu futhi izingxenye ezincane. Umphetho lokhu kwenza izinga elifanayo. Ngaphezu kwalokho, argon Welding titanium muhle iqiniso lokuthi kungenzeka ukusebenza ngesikhathi samanje encane, futhi ikuvumela ukushisela impahla kokuba ukushuba 0.5 mm. Argon Ungakwazi ukubuyisela imininingwane elahlekile ivolumu yabo yokuqala.

Welding titanium futhi Alloys yayo: Ubuchwepheshe

Umsebenzi kumele wenziwe uchwepheshe ofanelekayo nge imishini ezifanele. Ngaphezu kwalokho, le nqubo multi-step. Zonke izinyathelo okumelwe ziqhubeka sithuthukise esungulwe ukulandelana futhi wenziwa ngokuvumelana nezindinganiso.

Isigaba sokuqala - wokulungiselela. Kulesi sigaba kubalulekile ukuhlanza ebusweni metal. Kubaluleke kakhulu ukususa ifilimu oxide. Imiphetho ngokuvamile iphathwa oxyfuel indlela. Into noma workpiece licubunguliwe sasekhaya futhi acid (hydrochloric). Lokhu kufanele kugcinwe lokushisa njalo degrees 60 Celsius. Lapha kubalulekile ukuba ukuhlinzeka ngokuvikela metal iphathwa asabela kanjani umoya ozungeze umhlaba wethu kokubili ngaphandle kuthabathela ecaleni labaqaphi elingemuva. Kuze kube yimanje, ithusi noma steel pads efanelekayo ezidinga ukusetshenziswa umphetho. Ngaphezu pads avunyelwe ukusetshenziswa visors zokuzivikela kanye Imibhobho esemzimbeni ekhethekile.

Phakathi nenqubo Welding

Inqubo lwenzeka ngesikhathi samanje njalo. Sikaphalafini efakwe a tungsten electrode ekhethekile. Lapho metal iza ukuxhumana arc kagesi kwakhiwa pool weld. Izinga lokushisa ngokuvamile ifinyelela izinkulungwane 6 degrees Celsius.

Ngaphansi yokucindezela arc titanium oncibilikisiwe kancane kwaphoqa. It kuvela ukuthi sikaphalafini uzishisa ekhosombeni. Lokhu kungenziwa kubhekwe inzuzo njengoba ngcono kakhulu eyenza umuntu acabange eseZwini amandla. Ngaphezu kwalokho, njalo akhishwa argon, esinikela isivikelo ukuchayeka umoya-mpilo, i-nitrogen nezinye izinto.

Okuthile

Mayelana futhi ziphathwe titanium. Welding Cold kuhilela ukusetshenziswa yamathebhu wire kuphela uma ukushuba metal idlula 1.5 mm. Uma ukushuba kuyinto 10-15 mm, Welding wenziwa a kwamanzi arc ndima. Uma umsebenzi wenziwa ecabanga ngokugcinwa ubuchwepheshe, omhlophe webhola ayidingi ukucubungula kusukela slag. Kodwa kulabo abangakholwa kuyoba izinga bushelelezi futhi okusezingeni eliphezulu. compounds okunjalo zinezikhathi airtightness okusezingeni eliphezulu futhi ihlala isikhathi eside.

Arc Welding futhi electron ugongolo Welding

Zifakwa arc Welding kuyinto esanda kutholakala. Indlela isekelwe impahla ukwahlukanisa kusuka imvelo bangaphandle fluxes ekhethekile. Flux uhlobo unama. I esetshenziswa njalo kunazo ANT-A ezihlukahlukene zokulungisa. I engavamile indlela olugxile yokuthi kungenzeka ukuba sifinyelele crystal ngehele isakhiwo ungcono uma Welding ngaphansi kwesimo inert. Ngakho-ke, it is okungcono ngakho ziphathwe titanium. Welding titanium indlela esinjalo asisho ukuthi akudingeki zilulaza ukusebenza ingxenye.

Electron ugongolo Welding has nemiphumela ethile engathandeki eziningi. Kodwa kukhona inzuzo eyodwa ebalulekile, okuyinto ivikelwe ngokugcwele imvelo kwangaphandle metal. Lokhu kuvumela eliphezulu kakhulu izinga crystal ngehele. Uma le nqubo ithatha indawo ngesivinini, kunciphise amandla okuzamazama umsebenzi owawenziwa. Kukhona Welding electro-slag, okuyinto kuze kube manje akuzange wathola ukusatshalaliswa efanele. Sici Its liqukethe ukuthi electrode wasebenzisa ukwaziswa okufanayo njengoba ebusweni ashiselwe enqubeni.

isiphetho

Manje unalo ulwazi jikelele ukuthi Welding. Titanium inverter Welding okuyiwona sisetshenziswa kabanzi, has azifani. Yingakho-ke isetshenziswa lapho kungekho steel efanelekayo noma nezinye izinsimbi. Kodwa izindleko aphezulu imishini kwabashiselayo, umfutho wamandla yenqubo, kanye nezinye izinto eziningi ezimbi kukhona ungakuvumeli ukuba ukuthuthukiswa nokusetshenziswa kwale metal. Noma kunjalo, ezinye izinkampani njalo uzama ukwenza ngangokunokwenzeka ukuze wenze kube lula futhi kube lula ukuthola weld izinga. Ngokwesibonelo, umholi e yokuthengisa kwezithako kuyinto neliqinile 'Elf Villingen "-" Titan ". Welding Cold usebenzisa inkampani iba eziyinkimbinkimbi futhi isikhathi eside. Yiqiniso, i-Rookie namanje akakwazi ukubhekana msebenzi, kodwa kuchwepheshe kuyoba lula kakhulu ukuba yenze umsebenzi wayo. Ngokuyinhloko, lokhu kuyiso sonke isibopho kungaba kutjelwa Welding metal ezifana titanium.
