Kuyamba:
Zida zowotcherera za titaniyamu, kuphatikiza mbale za titaniyamu, ndodo, ndi machubu, zimafunikira njira zapadera chifukwa cha mawonekedwe awo apadera akuthupi ndi mankhwala. Kuwotcherera kwa Titanium kumachitika pogwiritsa ntchito njira yowotcherera ya Gas Tungsten Arc Welding (GTAW), yomwe imadziwikanso kuti Tungsten Inert Gas (TIG), yotetezedwa bwino ndi mpweya wa inert argon. Musanagwiritse ntchito, kuyera kwa gasi wa argon kumatsimikiziridwa poyang'ana chiphaso cha wopanga pa silinda ya mpweya, ndikutsatiridwa ndi kuwunika kwa valavu ya silinda chifukwa cha kutayikira kapena kusagwira bwino ntchito.

Zofunikira pakuwotcherera Mbale za Titanium ndi Ndodo za Titanium:

Malo owotcherera amayenera kutetezedwa kuti asaipitsidwe ndi mpweya wokhazikika monga nayitrogeni (N), mpweya (O), haidrojeni (H), ndi zinthu zoyipa zonyansa monga kaboni (C), chitsulo (Fe), manganese (Mn), etc. , pa kutentha pamwamba pa 250 ° C.
Argon Gasi: Argon yoyera ya Industrial-grade yokhala ndi chiyero chosachepera 99.98% ndi chinyezi chochepera 50 mg / m3 chiyenera kugwiritsidwa ntchito.
Kupanga mbewu zomangika kuyenera kupewedwa.
Kuwotcherera kwambiri kupsinjika kotsalira ndi zopindika ziyenera kupewedwa.
Kuonetsetsa kuti kuwotcherera kwabwino, njira yowotcherera iyenera kutsata njira zomangira zomwe zidakonzedweratu komanso miyezo yokhazikika yoyendetsera bwino nthawi zonse. Izi zimaphatikizapo kuwongolera kwathunthu kwa ogwira ntchito, makina, zida, ndi njira zotsimikizira kuwotcherera kwa machubu a titaniyamu munthawi yoyenera.

Zida Zowotcherera ndi Zida za Titanium:

Makina Owotcherera: Gwiritsani ntchito makina owotcherera a TIG omwe ali ndi mawonekedwe abwino kwambiri ogwirira ntchito komanso osinthika, okhala ndi magwiridwe antchito apano ndi ma voliyumu.
Wowotcherera Torch: Gwiritsani ntchito nyali yowotcherera ya QS-75 °/500 yoziziritsidwa ndi madzi ya TIG yoyenera malo osiyanasiyana owotcherera, yokhala ndi mawonekedwe osavuta, opepuka, olimba, thupi lamfuti lolimba, kutchinjiriza kwabwino, kutuluka kwa gasi wokhazikika, chosungira chotetezedwa cha tungsten, komanso kusinthika kwamitundu yosiyanasiyana. kuwotcherera zochitika.
Argon Gas Delivery Tube: Gwiritsani ntchito machubu apulasitiki olimba pang'ono m'malo mwa mipope ya rabala kapena zinthu zina zotengera chinyezi. Machubu odzipatulira ayenera kugwiritsidwa ntchito, kupewa kusakanikirana ndi machubu omwe amagwiritsidwa ntchito pamipweya ina. Kutalika kwa chubu la gasi la argon sayenera kupitirira 30m kuti mukhalebe ndi mphamvu yokhazikika komanso kutuluka kwa mpweya.
Zokonzera Zowotcherera: Gwiritsani ntchito zitsulo zosapanga dzimbiri za austenitic kapena zomangira zamkuwa ndi ma bolts okhoma pama mbale ndi zida za titaniyamu. Onetsetsani mphamvu yokhotakhota yokwanira kuti mukhale ogwirizana komanso zilolezo zoyenera.
Zida Zothandizira ndi Zida: Phatikizani zotchingira zotchingira mpweya wa argon, makina opera, mafayilo apadera, maburashi achitsulo chosapanga dzimbiri, ndi zina zambiri.
Waya Wowotcherera wa Titanium: Sankhani waya wowotcherera wa ERTi-2 womwe umakwaniritsa izi:
Chemical zikuchokera ndi mawotchi katundu ofanana ndi zinthu m'munsi.
Pazinthu zomwe zimafuna ductility kwambiri, gwiritsani ntchito waya wowotcherera wokhala ndi chiyero chapamwamba kuposa zinthu zoyambira.
Musanagwiritse ntchito, tsimikizirani zinthuzo poyang'ana zinthu, kuyang'ana chiphaso cha wopanga ndi zolemba zabwino. Onetsetsani kuti pamwamba pa waya wowotcherera ndi waudongo, wopanda ma oxidation, ming'alu, kusenda, zipsera, kapena ma slag inclusions.
Kutsiliza:
Zida zowotcherera za titaniyamu zimafunikira chidwi kwambiri panjira zowotcherera, zida, ndi zida chifukwa cha mawonekedwe awo apadera. Kutsatira mfundo zowotcherera mwamphamvu ndikugwiritsa ntchito zida ndi zida zoyenera kumatsimikizira kukhulupirika ndi mtundu wa zida zowotcherera za titaniyamu, zomwe zimathandizira kudalirika ndi magwiridwe antchito a titaniyamu ndi zinthu zomwe zimapangidwa.
