1. Izakhiwo ze-Metallic kanye nemingcele ye-welding ye-titanium
I-Titanium ine-gravity encane ethize (amandla adonsela phansi athize ngu-4.5), amandla aphezulu, ukumelana kahle namazinga okushisa aphezulu naphansi, kanye nokumelana nokuqhekeka okuhle kakhulu nokumelana nokugqwala ku-chlorine emanzi. Izakhiwo zemishini kanye nokushiselwa kwe-titanium kuhlobene nokuhlanzeka kwezinto ze-titanium. Ukuphakama kokuhlanzeka, kungcono ukusebenza kahle. Ukunciphisa ubumsulwa, ukwehla okubukhali kwepulasitiki nokuqina, futhi kubi kakhulu ukusebenza kokushisela. I-Titanium isebenza kakhulu ngaphezu kuka-300°C futhi imunca kalula ama-athomu e-hydrogen, umoya-mpilo kanye ne-nitrogen emazingeni okushisa aphezulu, okwenza izinto zibe brittle. I-Titanium iqala ukumunca i-hydrogen ezingeni lokushisa eliphezulu elingu-300°C, i-oxygen ku-600°C, ne-nitrogen ku-700°C.
Imishini yokushisela i-Argon arc kufanele ibe ne-high-frequency arc ignition, ukuncishiswa kwamanje, ukuvikela ukubambezeleka kwegesi, kanye nezintambo zokushisela idivayisi ye-pulse zidinga izakhiwo zemishini ezilingana nempahla yomzali.
Impahla yesembozo sokuzivikela kufanele ibe yinsimbi ensomi noma i-titanium, futhi umumo kufanele ulungele ukuvikela i-weld ukuvimbela i-weld ekushintsheni umbala. I-stainless steel wire mesh kufanele ifakwe ngaphakathi kwekhava yokuvikela ukuze idlale indima yokubhafa kwegesi.
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)
2. Ubuchwepheshe bokusebenza kwe-Titanium welding
Ukuhlanza ngaphambi kwe-welding:
Impahla igoqwe ngomshini we-engeli egoqayo, futhi isikali se-oxide, amafutha, ama-burrs, uthuli, njll. ngaphakathi kuka-25mm nhlangothi zombili zipholishwa ngebhulashi locingo, bese zesulwa nge-acetone noma i-ethanol.
Ukuvikelwa kokushisela:
Ngaphambi kokushisela, kufanele uqale ufunde ukuvikela i-argon. Lapho evikela, umuntu oyedwa ubamba isembozo sokuzivikela ukuze avikele uhlangothi olungaphezulu, kanti omunye ubamba isembozo sokuvikela ukuvikela uhlangothi olungezansi. Umvikeli kufanele abambisane kahle nomshiseli. Ngemuva kokushisela, isembozo sokuzivikela singakhululwa kuphela ngemuva kokuthi i-weld iphole. Ukuze uthole i-welding ehlangothini olulodwa kanye nokwakheka okuhlangene kabili, ukunakwa okukhethekile kufanele kukhokhwe ekuvikelweni kohlangothi olungemuva. Uma ingavikelwe kahle, i-welding liquid ayikwazi ukugeleza, futhi ngeke kube khona ukwakheka.
Lapho ushisela, i-weld kufanele ibe negebe elanele elingu-3-5mm ukuze kwakheke umgodi we-arc. Bamba isibhamu sokushisela esandleni sakho sokudla bese uzama ukwehlisa i-electrode ye-tungsten yesibhamu sokushisela. Bamba intambo yokushisela esandleni sakho kwesokunxele bese usebenzisa isithupha sakho nomunwe ophakathi nendawo ukuze ubambe intambo yokushisela bese uyithumela phambili. Uma uthumela ucingo lwe-welding, kufanele ugcine ukuqhubeka nokuzinza. Izandla zombili kufanele zibambisane kahle ukugcina i-weld flat. Amehlo kufanele ahlale ebuka ukujula kwechibi elincibilikisiwe kanye nokugeleza koketshezi olushiselayo. I-current kufanele ilungiswe ngokuvumelana nemithethonqubo futhi yamanje ngokweqile ayivunyelwe.
I-nozzle argon gas igcinwa ku-5ml, igesi evikelayo igcinwa ku-25ml, futhi ingemuva igcinwe ku-20ml ukuqinisekisa ukuthi i-weld ayishintshi umbala ngemva kwekhava yokuvikela. Lapho ushisela kabili, isikhathi esithile sokupholisa kufanele sishiywe ukuze kuncishiswe izinga lokushisa elingaphezulu libe ngaphansi kuka-200℃, ngaphandle kwalokho imifantu kanye nokushwabana kuzokwenzeka kalula. I-flat welding kanye ne-nozzle rotation welding kufanele isetshenziswe ngangokunokwenzeka.
Uma kushiselwa, igumbi kufanele lome futhi lingabi nothuli, isivinini somoya kufanele sibe ngaphansi kwamamitha angu-2 ngesekhondi, futhi imimoya enamandla ingabangela kalula ukungazinzi kwe-arc. Uma uhlanganisa i-welding, zama ukusebenzisa idivayisi ye-pulse ukwenza i-weld ibe yinhle.
3. Inqubo yokukhiqiza kanye nobuchwepheshe bokugcinwa kwemishini ye-titanium
Izinto ezisetshenziselwa ukucubungula amashubhu e-titanium, izindololwane ze-titanium, namathangi e-titanium kumele zihlangabezane nezidingo. Ukuqina kwabo, amandla, nokunwebeka kufanele kube nesitifiketi sepuleti. Ipuleti ngalinye le-titanium kufanele lilungiswe ngerula. Ubukhulu kufanele bubalwe lapho usikwa izinto zokuvimbela izinsalela eziningi. Imishini yokugunda kufanele isetshenziswe lapho kusikwa amapuleti, futhi ukusika igesi kufanele kugwenywe ngangokunokwenzeka. Imigqa kufanele imakwe ngokucacile nangokunembile uma usebenzisa amapayipi. Ukusetshenziswa okuphindaphindiwe kokusika igesi kunqatshelwe ngokuphelele. Ngemuva kokusika ipuleti, umshini wokuchama kufanele usetshenziselwe ukwenza umsele. Imifantu kufanele ifane. Ngemuva kokuthi ipuleti ligoqwe ngumshini wokugoqa ipuleti okokuqala, i-weld kufanele ibe yi-concave kancane ukuze kube lula ukubunjwa kwesibili ngemuva kokushisela. Ngenxa yokuthi intengo yezinto ze-titanium iphezulu (cishe amayuan angu-140/Kg wezinto ezingavuthiwe futhi cishe 400 yuan/Kg ngemva kokucubungula), imfucuza kufanele igwenywe.
Kunomehluko omkhulu phakathi kokugcinwa nokulungiswa kwamapuleti e-titanium. Izinto eziyinhloko zihlanganisa izici zemvelo, izinguquko ezibonakalayo, njll. I-weld kufanele ivikelwe uma ingavikelwa. Uma kungenakwenzeka ngempela ukuvikela izinhlangothi zombili, sebenzisa isivikelo esincane samanje sohlangothi olulodwa. Ngemuva kokuqhekeka kwe-weld, ungashiseli kwi-weld yasekuqaleni. Ukushisela kufanele kwenziwe ngokunamathisela ipuleti. Lapho indawo yokushisela inomoya, kufanele kube nendawo yokukhosela umoya, futhi iseyili noma ipuleti lensimbi kufanele isetshenziselwe ukuvikela. Lapho uthatha ipayipi, kufanele kube negebe noma ukushisela okumile ngoba ngaphakathi akukwazi ukuvikeleka. I-weld kufanele inwetshwe ngendlela efanele futhi ijiywe.
