1. Metallic katundu ndi kuwotcherera magawo titaniyamu
Titaniyamu ili ndi mphamvu yokoka yaying'ono (kukoka kwapadera ndi 4.5), mphamvu yayikulu, kukana bwino kuzizira kwambiri komanso kutsika, komanso kukana ming'alu komanso kukana dzimbiri mu chlorine yonyowa. The makina katundu ndi kuwotcherera titaniyamu zimagwirizana ndi chiyero zipangizo titaniyamu. Kukwera kwa chiyero, kumachita bwino. Kutsika kwa chiyero, kuchepa kwakukulu kwa pulasitiki ndi kulimba, komanso kuwonjezereka kwa kuwotcherera. Titaniyamu imagwira ntchito kwambiri kuposa 300 ° C ndipo imatenga mosavuta maatomu a haidrojeni, okosijeni ndi nayitrojeni pakatentha kwambiri, zomwe zimapangitsa kuti zinthuzo zisawonongeke. Titaniyamu imayamba kuyamwa haidrojeni pa kutentha kwambiri kwa 300°C, mpweya pa 600°C, ndi nayitrojeni pa 700°C.
Makina owotcherera a Argon arc ayenera kukhala ndi poyatsira ma arc okwera kwambiri, kutsika kwapano, kuteteza kuchedwa kwa gasi, ndi mawaya akuwotcherera a zida zimafunikira zida zamakina zofanana ndi zida za makolo.
Zinthu za chivundikiro chotetezera ziyenera kukhala chitsulo chofiirira kapena titaniyamu, ndipo mawonekedwewo ayenera kukhala abwino poteteza weld kuti asasinthe mtundu. Waya wachitsulo wosapanga dzimbiri uyenera kuyikidwa mkati mwa chivundikiro chotetezera kuti ugwire ntchito yotchinga mpweya.
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)
2. Titaniyamu kuwotcherera ntchito luso
Kuyeretsa musanawotchere:
Zinthuzo zimakutidwa ndi makina opukutira, ndipo sikelo ya oxide, mafuta, burrs, fumbi, ndi zina zambiri mkati mwa 25mm mbali zonse zimapukutidwa ndi burashi yawaya, kenako ndikupukuta ndi acetone kapena ethanol.
Chitetezo cha Welding:
Musanayambe kuwotcherera, muyenera kuphunzira kaye chitetezo cha argon. Poteteza, munthu mmodzi amakhala ndi chivundikiro chotetezera kuti ateteze kumtunda, ndipo winayo akugwira chivundikiro chotetezera kuti ateteze mbali yapansi. Woteteza ayenera kugwirizana bwino ndi wowotchera. Pambuyo kuwotcherera, chivundikiro chotetezera chimatha kumasulidwa kokha pambuyo pozizira. Kwa kuwotcherera mbali imodzi ndi kupanga mbali ziwiri, chidwi chapadera chiyenera kuperekedwa ku chitetezo cha mbali yakumbuyo. Ngati sichitetezedwa bwino, madzi otsekemera sangathe kuyenda, ndipo sipadzakhalanso kupanga.
Powotcherera, chowotchereracho chiyenera kukhala ndi kusiyana kokwanira 3-5mm kuti apange dzenje la arc. Gwirani mfuti yowotcherera m'dzanja lanu lamanja ndikuyesa kutsitsa ma elekitirodi a tungsten amfuti yowotcherera. Gwirani waya wowotchera m'dzanja lanu lamanzere ndipo gwiritsani ntchito chala chanu chachikulu ndi chala chapakati kuti mutseke waya wowotcherera ndikutumiza patsogolo. Potumiza waya wowotcherera, muyenera kukhalabe kupitiriza komanso kukhazikika. Manja awiriwa agwirizane bwino kuti weld ikhale yosalala. Nthawi zonse maso ayenera kuyang'ana kuya kwa dziwe losungunuka ndi kutuluka kwa madzi otsekemera. Zamakono ziyenera kusinthidwa molingana ndi malamulo ndipo zowonjezereka ndizoletsedwa.
Mpweya wa argon wa nozzle umasungidwa pa 5ml, mpweya wotetezera umasungidwa pa 25ml, ndipo kumbuyo kumasungidwa pa 20ml kuonetsetsa kuti weld sasintha mtundu pambuyo pa chivundikiro chotetezera. Mukawotchera kawiri, nthawi ina yozizirira iyenera kusiyidwa kuti kutentha kwapansi kukhale pansi pa 200 ℃, apo ayi ming'alu ndi brittleness zitha kuchitika. Kuwotcherera kwa lathyathyathya ndi kuwotcherera kwa nozzle kuyenera kugwiritsidwa ntchito momwe mungathere.
Powotcherera, chipindacho chiyenera kukhala chouma komanso chopanda fumbi, liwiro la mphepo liyenera kukhala lochepera 2 metres / sekondi, ndipo mphepo yamkuntho imatha kuyambitsa kusakhazikika kwa arc. Mukamawotchera, yesetsani kugwiritsa ntchito chipangizo cha pulse kuti chowotchereracho chikhale chokongola.
3. Njira yopangira ndi kukonza ukadaulo wa zida za titaniyamu
Zida zomwe zimagwiritsidwa ntchito pokonza machubu a titaniyamu, ma elbows a titaniyamu, ndi akasinja a titaniyamu ziyenera kukwaniritsa zofunikira. Kulimba kwawo, mphamvu, ndi kukhazikika kwawo ziyenera kukhala ndi satifiketi ya mbale. Mbale iliyonse ya titaniyamu iyenera kusinthidwa ndi wolamulira. Kukula kuyenera kuwerengedwa podula zida kuti mupewe zinyalala zochulukirapo. Makina ometa ayenera kugwiritsidwa ntchito podula mbale, ndipo kudula gasi kuyenera kupewedwa momwe mungathere. Mizere iyenera kukhala yodziwika bwino komanso yolondola mukamagwiritsa ntchito mapaipi. Kugwiritsa ntchito mobwerezabwereza kudula gasi ndikoletsedwa. Mukadula mbaleyo, makina osokera amayenera kugwiritsidwa ntchito popanga poyambira. Mikwingwirima iyenera kukhala yofanana. Pambuyo mbale ndi adagulung'undisa ndi mbale anagubuduza makina kwa nthawi yoyamba, weld ayenera pang'ono concave kuti atsogolere wachiwiri kuwumba pambuyo kuwotcherera. Chifukwa mtengo wa titaniyamu ndi wokwera (pafupifupi 140 yuan/Kg kwa zopangira ndi pafupifupi 400 yuan/Kg pambuyo pokonza), zinyalala ziyenera kupewedwa.
Pali kusiyana kwakukulu pakati pa kukonza ndi kukonza mbale za titaniyamu. Zinthu zazikuluzikulu zimaphatikizapo zinthu zachilengedwe, kusintha kwa zinthu, etc. Weld iyenera kutetezedwa ngati ingatetezedwe. Ngati ndizosatheka kuteteza mbali zonse ziwiri, gwiritsani ntchito chitetezo chaching'ono chambali imodzi. Pambuyo powotcherera ming'alu, musawotchere pa weld woyambirira. Kuwotcherera kuyenera kuchitidwa ndi chigamba mbale. Malo owotchererapo pakakhala mphepo, payenera kukhala pobisalira mphepo, ndipo nsalu kapena mbale yachitsulo iyenera kugwiritsidwa ntchito poteteza. Mukatenga chitoliro, payenera kukhala mpata kapena kuwotcherera mozama chifukwa mkati mwake sungatetezedwe. Chowotchereracho chiyenera kukulitsidwa moyenera ndi kukhuthala.
