Zotsatira Zabwino Za Mafuta Oyenera
Mu Laser Kuwiritsa, kusankha kwa mpweya woteteza kumatha kukhudza kwambiri mapangidwe, mawonekedwe, kuya, ndi kumaliridza a sewero. Munthawi zambiri, kuyambitsa mpweya wotchinjiriza kuli ndi zotsatira zabwino pa msoko. Komabe, imathanso kukhala ndi zovuta. Zotsatira Zabwino Zogwiritsa Ntchito Magesi Olondola Ndiwo:
1. Kutetezedwa koyenera kwa dziwe
Kukhazikitsidwa koyenera kwa mpweya woteteza kumatha kutchingira bwino dziwe la maxidation kapena ngakhale mpweya wabwino.
2. Kuchepetsa kwapakati
Kuyambitsa mpweya woteteza kumatha kuchepetsa kutupa nthawi yotentha.
3. Mapangidwe a yunifolomu ya sewero
Kukhazikitsidwa koyenera kwa gasi yoteteza kumalimbikitsa kufalikira kwa dziwe la weld polimbana, zomwe zimapangitsa yunifolomu komanso kusangalatsa kosangalatsa.
4. Kuchulukitsa kwa laser
Kuyambitsa Magesi oteteza kumatha kuchepetsa kutchinga kwa zitsulo zamiyala kapena plasma pamtambo, potero kuwonjezereka laser.
5. Kuchepetsa kwa mafuta
Kuyambitsa mpweya woteteza kumatha kuchepetsa mapangidwe a ma pores a mpira wa weld. Posankha mtundu woyenera wamafuta, kuchuluka kwa madzi, ndi njira zoyambira, zotsatira zabwino zitha kutheka.
Komabe,
Kugwiritsa ntchito mpweya molakwika kumatha kukhala ndi zotsatirapo zowononga. Zotsatira zoyipa zimaphatikizapo:
1. Kuwonongeka kwa msoko wa weld
Kukhazikitsidwa kosayenera kwa mpweya woteteza kumatha kubweretsa chisamaliro chosauka.
2. Kugwedeza ndikuchepetsa makina
Kusankha mtundu wolakwika wa gasi ungayambitse ku wed Strew Kusweka ndikuchepetsa magwiridwe antchito.
3. Kuchulukitsa kwa oxida kapena kusokoneza
Kusankha mpweya wolakwika, kaya kukwera kwambiri kapena kutsika kwambiri, kumatha kuyambitsa makutidwe ozizira a weld. Zimathanso kuyambitsa chisokonezo chachikulu kwa chitsulo chosungunuka, chifukwa cha kugwa kapena kukhazikitsidwa kosagwirizana ndi msoko wa weld.
4.. Chitetezo chokwanira kapena chosalimbikitsa
Kusankha njira yolakwika yamagesi yosiyidwa imatha kuteteza chitetezo chokwanira msoko wokazinga kapena ngakhale kuwononga mapangidwe a msoko wokaziyo.
5. Kukopa pa Kuzama kwa Welld
Kuyambitsidwa kwa mpweya wotchinga kumatha kukhudzanso kuyamwa kwa welld, makamaka mu kuwotcherera mbale woonda, pomwe umayamba kuchepetsa kuya kwa wed.

Mitundu ya mipweya yoteteza
Magesi oteteza omwe amagwiritsidwa ntchito mu laser amawuma ndi nayitrogeni (N2), Argon (AR), ndi Helium (). Magulu awa amakhala ndi zinthu zosiyana zakuthupi ndi mankhwala, zomwe zimapangitsa kuti pakhale zovuta zina.
1. Nayitrogeni (N2)
N2 ili ndi mphamvu zolimbitsa thupi zolimbitsa thupi, zapamwamba kuposa ARR ndi kutsika kuposa iye. Pansi pa laser, imakhala ndi digiri yochepetsetsa, moyenera kuchepetsa mapangidwe a plasma ndikuwonjezera kugwiritsa ntchito kwa laser. Komabe, nayirogeni amatha kuchita ndi ma aluminium olosi ndi chitsulo cha kaboni nthawi ina, ndikupanga nitrides. Izi zitha kuwonjezera kutsekemera ndikuchepetsa kulimba kwa msoko wowonda, kusokoneza mphamvu zake. Chifukwa chake, kugwiritsa ntchito nayitrogeni ngati mpweya woteteza kwa aluminiyamu overlos ndi minyewa yachisoni osavomerezeka. Kumbali ina, nayitrogeni angachite ndi chitsulo chosapanga dzimbiri, ndikupanga ma nitrodes omwe amathandizira kulimba kwa cholumikizira. Chifukwa chake, nayitrogeni amatha kugwiritsidwa ntchito ngati mpweya woteteza kuti uziwotcha chitsulo chosapanga dzimbiri.
2. Argon Gasi (AR)
Gasi wa Argon ali ndi mphamvu zochepa kwambiri, zomwe zimapangitsa kuti iyoniriza ikhale pansi pa laser. Izi ndizosavuta kuwongolera mapangidwe a mitambo ya plasma ndipo imatha kukhudzana ndi kugwiritsa ntchito kwa ma Lasers. Komabe, argon ali ndi chipongwe chotsika kwambiri ndipo sizikuwoneka kuti zikuchitika pamankhwala wamba. Kuphatikiza apo, Argon ndiokwera mtengo. Kuphatikiza apo, chifukwa cha kuchuluka kwake, Argon amatsikira pamwamba pa dziwe lowonera, ndikuteteza bwino dziwe. Chifukwa chake, itha kugwiritsidwa ntchito ngati mpweya wotchinga.
3. Gasi lamphamvu (iye)
Gayium Gasi ili ndi mphamvu zokulirapo, zomwe zimatsogolera ku Ionirization pansi pa laser. Zimalola kuwongolera bwino mapangidwe a plasma, ndipo ma lasers amatha kulumikizana bwino ndi zitsulo. Kuphatikiza apo, helium ali ndi nkhawa kwambiri ndipo samachita mosavuta pamankhwala okhala ndi zitsulo, ndikupangitsa kukhala gasi yabwino kwambiri kuti ilowerere. Komabe, mtengo wa helium ndi wokwera, kotero nthawi zambiri samagwiritsidwa ntchito popanga zinthu. Amakhala olemba ntchito pa kafukufuku wa sayansi kapena zinthu zowonjezera kwambiri.

Njira zodziwitsira mpweya wokhazikika
Pakadali pano pali njira ziwiri zodziwitsira mpweya wotchinga: mbali-bais mbali yophulika ndi mpweya wotchinga, monga tikuonera Chithunzi 1 ndi Chithunzi 2, motero 2, motero.
Chithunzi 1: Kumanzere-kumbuyo kwa mpweya wotchinga
Chithunzi 2: gasi yoteteza mafuta
Kusankha pakati pa njira ziwiri zowomba zimatengera malingaliro osiyanasiyana. Mwambiri, tikulimbikitsidwa kugwiritsa ntchito njira yowombera yamphesa ya mpweya woteteza mpweya wabwino.

Mfundo Zosankhira Njira Yodziwitsa Mpweya Wopanda Chitetezo
Choyamba, ndikofunikira kumveketsa kuti mawu oti "ma okosi" a weds ndi mawu a colloque. Chiphunzitsocho, chimanena za kuwonongeka kwa zinthu zambiri chifukwa cha zomwe zimachitika pakati pa zitsulo zazitsulo ndi zovulaza mlengalenga, nitrogen, ndi haitrogeni.
Kuletsa oxidation kumaphatikizapo kuchepetsa kapena kupewa kulumikizana pakati pa zinthu zoyipa izi ndi chitsulo chotentha kwambiri. Dziko lotentha kwambiri limaphatikizapo chitsulo cha dziwe lokhalo komanso nthawi yonseyo chitsulo chokazinga chikasungunuka mpaka dziwe linachepa pansi pakhomo.
Mwachitsanzo, kuwotcherera kwa Titanium matonthoza, pomwe matenthedwe ali pamwamba 300 ° C, kutengera mitundu yofulumira ya haidrogen imachitika; Pamwamba pa 450 ° C, zopondera zopondera mpweya wambiri, zimachitika; Ndipo kupitirira 600 ° C, mayamwidwe a nayitrogeni amatenga. Chifukwa chake, chitetezo chokwanira chimafunikira kuti titanium aloya omwe amaliwala nthawi yomwe imakhazikika ndipo kutentha kwake kumachepa pansi pa 300 ° C kuti mupewe makhiadation. Kutengera mafotokozedwe pamwambapa, zikuwonekeratu kuti kuwomba kwa mpweya wotchinga kumafunikira chitetezo osati kwa dziwe lotayirira lokha nthawi yoyenera komanso dera lokhazikika la weld. Chifukwa chake, njira yophulitsira pansi pa intaneti yomwe ili pachiwonetsero 1, makamaka dera lokhazikika la weld. Komabe, pazithunzi zina, kusankha kwa njirayi kumafunikira kupangidwa malinga ndi kapangidwe kazinthu komanso kusinthidwa kolumikizira.

Kusankha mwachindunji ndi njira yodziwitsira mpweya wotchinga
1. Mzere wowongoka
Ngati mawonekedwe azogulitsa ndiowongoka, monga momwe mawonekedwe 3, Chithunzi 1.
Chithunzi 3: Mzere wowongoka
2. Kenk adatseka geometry wed
Monga taonera Chithunzi 4, kuwombera mu mtundu uwu kwa mtundu wake umakhala ndi mawonekedwe otsekeka, monga mawonekedwe ozungulira, polybonal, kapena angapo. Kusintha kolumikizana kumatha kuphatikiza kulumikizana, kulumikizana kwa lap, kapena ma weds. Kwa mtundu uwu wa malonda, njira yomwe amakonda ndikugwiritsa ntchito gasi yotetezedwa yomwe ili patsamba 2.
Chithunzi 4: Kenkar adatseka geometry weld
Kusankhidwa kwa mpweya wotetezedwa kwa makonzedwe otsekeka otsekeka kumakhudza mwachindunji mtundu, ndikuwononga mphamvu. Komabe, chifukwa cha kusiyanasiyana kwa zinthu zoweta, kusankha kwa mafuta owuma ndi zovuta m'machitidwe owotchera. Pamafunika kuganizira kwambiri zinthu zoweta, kuwotcherera njira, kumatchera maulendo, ndi zotulukapo zoweta. Kusankhidwa kwa gasi yabwino kwambiri yotentha kumatha kutsimikiza mtima poyendetsa zotsatira zowoneka bwino.
