Titaniyamu aloyi ndi otsika kachulukidwe, mkulu mwachindunji mphamvu, zabwino dzimbiri kukana, otsika matenthedwe madutsidwe, sanali poizoni ndi sanali maginito, ndipo akhoza welded; amagwiritsidwa ntchito kwambiri mu ndege, zamlengalenga, mankhwala, mafuta, magetsi, zachipatala, zomangamanga, katundu wamasewera ndi zina.
Njira zowotcherera wa titaniyamu ndi titaniyamu aloyi ndi monga: kuwotcherera argon arc, kuwotcherera arc pansi pamadzi, vacuum electron mtengo kuwotcherera, etc.
Kukonzekera pamaso kuwotcherera
The pamwamba khalidwe la kuwotcherera ndi titaniyamu kuwotcherera waya ali ndi chikoka kwambiri pa makina zimatha welded olowa, choncho ayenera mosamalitsa kutsukidwa.
1) Kuyeretsa makina: Kwa ma welds omwe safuna kuwotcherera kwambiri kapena ovuta kunyamula, sandpaper yabwino kapena maburashi achitsulo osapanga dzimbiri angagwiritsidwe ntchito kuwapukuta, koma ndibwino kugwiritsa ntchito carbide yellow kukwapula mbale ya titaniyamu kuchotsa filimu ya oxide.
2) Kuyeretsa kwa Chemical: Musanayambe kuwotcherera, chidutswa choyesera ndi waya wowotcherera amatha kuzifutsa. Yankho la pickling likhoza kukhala HF (5%) + HNO3 (35%) yankho lamadzi. Muzimutsuka ndi madzi oyera pambuyo pickling, ndi kuwotcherera mwamsanga mutayanika. Kapena gwiritsani ntchito acetone, ethanol, carbon tetrachloride, methanol, ndi zina zotero kupukuta poyambira mbale ya titaniyamu ndi mbali zonse ziwiri (mkati mwa 50mm iliyonse), pamwamba pa waya wowotcherera, ndi mbali yomwe chipangizocho chimakhudza mbale ya titaniyamu.
3) Kusankhidwa kwa zida zowotcherera: Pamawotcherera a argon arc a titaniyamu ndi titaniyamu alloy tungsten mbale, gwero lamagetsi la DC argon arc lokhala ndi mawonekedwe akunja ndi kuyambitsa kwapamwamba kwa arc liyenera kusankhidwa, ndipo nthawi yochedwetsa gasi iyenera kukhala yosachepera. Masekondi 15 kuti mupewe makutidwe ndi okosijeni komanso kuipitsidwa kwa weldment.
4) Kusankhidwa kwa zida zowotcherera: Kuyera kwa gasi wa argon kuyenera kukhala kosachepera 99.99%, mame ayenera kukhala pansi -40 ℃, ndipo gawo lonse la zonyansa liyenera kukhala 0.001%. Kukakamiza kwa silinda ya argon kutsika mpaka 0.981MPa, iyenera kuyimitsidwa kuti isakhudze mtundu wa olowa.
Zida zowotcherera za Xinfa zili ndi mawonekedwe apamwamba komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:Opanga Kuwotcherera & Kudula - China Welding & Cutting Factory & Suppliers (xinfatools.com)
5) Chitetezo cha gasi ndi kutentha kwa kuwotcherera: Kulumikizana kwa chitoliro cha titaniyamu kumakhala kochepa panthawi yowotcherera. Pofuna kupewa kuwotcherera olowa kuti asaipitsidwe ndi mpweya woipa ndi zinthu pa kutentha kwambiri, malo kuwotcherera ndi kuwotcherera ayenera pansi pa kofunika kuwotcherera chitetezo ndi kulamulira kutentha, ndi kutentha ayenera kukhala pansi 250 ℃.
Malangizo Ogwiritsira Ntchito
1. Popanga kuwotcherera kwa argon arc pamanja, ngodya yocheperako (10 ~ 15 °) iyenera kusungidwa pakati pa waya wowotcherera ndi kuwotcherera. Waya wowotcherera uyenera kudyetsedwa mu dziwe losungunuka pang'onopang'ono komanso molingana kumapeto kwa dziwe losungunuka, ndipo mapeto a waya wowotcherera asamasunthidwe kunja kwa malo otetezedwa a argon.
2. Pamene kuwotcherera, mfuti yowotcherera kwenikweni simagwedezeka mopingasa. Ikafunika kugwedezeka, mafupipafupi ayenera kukhala otsika ndipo kugwedezeka kwa mafunde kuyenera kukhala kwakukulu kwambiri kuti asasokoneze chitetezo cha mpweya wa argon.
3. Mukathyola arc ndikumaliza kuwotcherera, pitirizani kudutsa chitetezo cha argon mpaka chowotcherera ndi chitsulo m'dera lomwe lakhudzidwa ndi kutentha kuzizire mpaka pansi pa 350 ℃ musanachotse mfuti yowotcherera.
Mtundu wapamwamba wa weld ndi zone yokhudzidwa ndi kutentha
1. Weld zone
Siliva yoyera, yopepuka yachikasu (yololedwa pawotchi yoyamba, yachiwiri ndi yachitatu); mdima wachikasu (wololedwa kwa welds wachiwiri ndi wachitatu); chibakuwa chagolide (chololedwa pamlingo wachitatu welds); buluu wakuda (wosaloledwa pawotchi woyamba, wachiwiri ndi wachitatu).
2. Malo okhudzidwa ndi kutentha
Siliva yoyera, yopepuka yachikasu (yololedwa pawotchi yoyamba, yachiwiri ndi yachitatu); mdima wachikasu, wofiirira wagolide (wololedwa kwa ma welds achiwiri ndi achitatu); buluu wakuda (wololedwa pamlingo wachitatu welds).
