Zosefera zowotcherera zodzipangitsa mdima zimayimira kupambana kwakukulu pachitetezo cha mafakitale, kupita patsogolo kwakukulu komwe kumatsimikizira chitetezo chokwanira cha maso a ma welder. Pakuchulukirachulukira kwa njira zowotcherera moyenera m'mafakitale, kukulitsa zosefera zowotcherera kwakhala kofunikira. Nkhaniyi ikuwunikira mozama momwe zosefera zowotcherera zimagwirira ntchito, mbiri yake, ukadaulo wopezeka, komanso momwe mungasankhire fyuluta yodalirika yowotcherera.
1. Mfundo yogwiritsira ntchito fyuluta yowotcherera:
Zosefera zowotcherera, zomwe zimadziwikanso kuti zipewa zowotcherera, zimagwira ntchito potengera mfundo za kusefa ndi mthunzi. Zoseferazi zimakhala ndi magetsi komanso makina, zimateteza maso a owotcherera ku cheza choopsa cha ultraviolet (UV) ndi infrared (IR). Pogwiritsa ntchito ukadaulo wopangitsa mdima wodziwikiratu, fyuluta yowotcherera imatha kusinthasintha komanso kusintha mulingo wa shading molingana ndi njira yowotcherera kuti wowotchererayo azitha kuwona bwino.
Chigawo chachikulu chomwe chimayang'anira kusintha mawonekedwe ndi Liquid Crystal yomwe ili mkati mwa fyuluta. Izi madzi krustalo amatha kusintha mandala malinga ndi mphamvu ya kuwotcherera arc anatulutsa pa ndondomeko kuwotcherera. Masensa a Arc mosalekeza amayang'anira ntchito yowotcherera ndikutumiza chizindikiro mwachangu ku LC kuti asinthe mthunzi wakuda, kenako ndikuteteza kwambiri maso a wowotcherera.
2. Mbiri ya chitukuko cha kuwotcherera fyuluta:
Mbiri ya zosefera zowotcherera idayamba chakumayambiriro kwa zaka za m'ma 1940, pomwe kuwotcherera kwa arc kudayamba kugwiritsidwa ntchito kwambiri. Poyamba, masks owotchera anali ndi magalasi akuda osasunthika omwe amapereka chitetezo chochepa cha UV ndi IR. Ma lens akudawa sanapereke kusintha kolondola kwa mthunzi kapena chitetezo chosasinthika, zomwe zidapangitsa kuvulala kwamaso kangapo pakati pa owotcherera.
M'kupita kwa nthawi, kufunikira kwa miyezo yotetezedwa bwino kunapangitsa kupanga zosefera zowotcherera zosiyanasiyana. M'zaka za m'ma 1980, zosefera zamagetsi zowotcherera zidawonekera, kuphatikiza masensa arc ndi mapanelo a LCD. Kupita patsogolo kumeneku kwasintha ntchito yowotcherera chifukwa zoseferazi zimathandizira kusintha kwa mithunzi, kuwonetsetsa kuti chitetezo chowotcherera chichuluke komanso kuwoneka.
3. Ukadaulo womwe ulipo wa fyuluta yowotcherera:
1) Sefa Yoyimitsa Payokha (ADF):
Ukadaulo wodziwika kwambiri pazosefera zamakono zowotcherera ndi ADF, yomwe imagwiritsa ntchito masensa ophatikizika komanso kusintha kwa tint kuti ipereke chitetezo chamaso chosayerekezeka. Mothandizidwa ndi mabatire ndi mapanelo adzuwa, zoseferazi zimakhudzidwa kwambiri ndi arc yowotcherera ndipo zimatha kusintha mthunzi wakuda pasanathe sekondi imodzi.
2) Ma lens amtundu wosiyanasiyana:
Magalasi amithunzi osinthika, omwe amadziwikanso kuti ma lens osinthika, amalola ma welders kuti asinthe pamanja mdima malinga ndi zofunikira zowotcherera. Ma lens awa amapereka kusinthasintha kwa ma welder omwe amagwira ntchito zosiyanasiyana zowunikira komanso njira zowotcherera.
3) Mtundu Weniweni:
Ukadaulo wa True Colour umapangitsa kuwala kowoneka bwino kudzera pa fyuluta, nthawi yomweyo kutsekereza ma radiation oyipa a UV / IR, kupatsa welder mawonekedwe apamwamba.
4. Dziwani Zosefera Zodalirika:
1) Kutsata mfundo zachitetezo:
Posankha fyuluta yowotcherera, ndikofunikira kuwonetsetsa kuti ikugwirizana ndi mfundo zachitetezo zomwe zimakhazikitsidwa ndi mabungwe owongolera, monga CE, ANSI, CSA, AS/NZS...
2) Kuwonekera kwa kuwala ndi nthawi yosinthira:
Zosefera zowotcherera zapamwamba kwambiri zimapereka kuwala kwapadera, zomwe zimalola ma welder kuzindikira ntchito yawo molondola. Kuphatikiza apo, nthawi yosinthira mwachangu (nthawi zambiri yosakwana 1/20,000 ya sekondi) ndiyofunikira kuteteza maso a wowotcherera ku kuwala kwadzidzidzi.
3) Kuwongolera ndi magwiridwe antchito osavuta:
Zosefera zili ndi maulamuliro osavuta kugwiritsa ntchito, monga mabatani akulu kapena mawonekedwe okhudza kukhudza, kumathandizira kugwiritsa ntchito mosavuta ndikusintha pakawotcherera. Zina zowonjezera monga kuwongolera tcheru, njira zogayira ndi kuchedwetsa kumapangitsanso kuthekera kwa fyuluta yowotcherera.
Pomaliza
Mwa kuphatikiza ukadaulo wopangitsa mdima wokha, zoseferazi zimakulitsa chitetezo chokwanira komanso kuchita bwino, kukulitsa zokolola ndikuchepetsa kuvulala. Kuti mudziwe fyuluta yodalirika yowotcherera, kutsata miyezo yachitetezo, kumveka bwino kwa kuwala, nthawi yosinthira mwachangu, kulimba, komanso mawonekedwe osavuta kugwiritsa ntchito ndi zinthu zofunika kuziganizira. Ndi kupita patsogolo kosalekeza kwaukadaulo wazosefera zowotcherera, ma welder tsopano amatha kugwira ntchito pamalo otetezeka komanso omasuka, kuwonetsetsa kuti maso awo ali ndi thanzi komanso moyo wautali.
