Izihlungi zokushisela ezizenza kube mnyama zimele impumelelo ebalulekile ekuphepheni kwezimboni, intuthuko enkulu eqinisekisa ukuvikeleka okuphezulu kwamehlo abashiseli. Ngokukhula kwesidingo sezinqubo zokushisela ezisebenzayo kuzo zonke izimboni, ukuthuthukiswa kwezihlungi zokushisela sekubaluleke kakhulu. Lesi sihloko sinikeza ukubheka okujulile kokuthi izihlungi ze-weld zisebenza kanjani, umlando, ubuchwepheshe obutholakalayo, kanye nendlela yokukhetha isihlungi esithembekile sokushisela.
1. Umgomo wokusebenza wesihlungi sokushisela:
Izihlungi zokushisela, ezaziwa nangokuthi izigqoko zokushisela, zisebenza ngokususelwe kumgomo wokuhlunga optical kanye ne-shading. Njengoba zifakwe imisebenzi kagesi nemishini, lezi zihlungi zivikela amehlo abashiselayo emisebeni eyingozi ye-ultraviolet (UV) kanye ne-infrared (IR). Ngokwamukela ubuchwepheshe obuzenzakalelayo bobumnyama, isihlungi se-welding singakwazi ukushintsha ngokuguquguqukayo futhi ngokuzenzakalelayo izinga le-shading ngokuvumelana nenqubo yokushisela ukuze kuqinisekiswe ukuthi i-welder ingathola umbono ongcono kakhulu.
Ingxenye eyinhloko enesibopho sokulungisa ukubonakala i-Liquid Crystal engaphakathi kwesihlungi. Le crystal ewuketshezi iyakwazi ukushintsha ukubonakala kwayo ngokuya ngokuqina kwe-arc yokushisela ekhishwe ngesikhathi senqubo yokushisela. Izinzwa ze-Arc zihlale ziqapha ukusebenza kokushisela futhi zithumela isignali ngokushesha ku-LC ukuze ilungise umthunzi omnyama, bese ihlinzeka ngokuvikeleka okuphezulu kwamehlo omshiseli.
2. Umlando wokuthuthuka wesihlungi sokushisela:
Umlando wezihlungi zokushisela uhlehlela emuva ekuqaleni kwawo-1940, lapho ukushisela kwe-arc kusetshenziswa kabanzi. Ekuqaleni, imaski yokushisela yayihlanganisa amalensi amnyama angashintshi ayenikeza ukuvikelwa okulinganiselwe kwe-UV ne-IR. Lawa ma-lens aluhlaza awazange anikeze ukulungiswa komthunzi okunembile noma ukuvikeleka okungaguquki, okuholele ekulimaleni kwamehlo okuningi phakathi kwama-welders.
Ngokuhamba kwesikhathi, isidingo sezindinganiso zokuphepha ezithuthukisiwe sabangela ukuthuthukiswa kwezihlungi zokushisela eziguquguqukayo. Ngawo-1980, kwavela izihlungi zokushisela nge-elekthronikhi, ezihlanganisa izinzwa ze-arc namaphaneli e-LCD. Lezi ntuthuko ziye zashintsha imboni yokushisela njengoba lezi zihlungi zivumela ukulungiswa komthunzi okuzenzakalelayo, okuqinisekisa ukuphepha okukhulayo nokubonakala kokushisela.
3. Ubuchwepheshe obukhona besihlungi sokushisela:
1) Isihlungi Sokwenza Ubumnyama Ngokuzenzakalelayo (ADF):
Ubuchwepheshe obudume kakhulu ezihlungini zesimanje zokushisela i-ADF, esebenzisa inhlanganisela yezinzwa kanye nokulungiswa kwe-tint okuzenzakalelayo ukuze kunikeze ukuvikelwa kwamehlo okungenakuqhathaniswa. Inikwe amandla amabhethri namaphaneli elanga, lezi zihlungi zizwela kakhulu ku-arc yokushisela futhi zingalungisa umthunzi omnyama ngaphansi kwesekhondi.
2) Ilensi yomthunzi oguquguqukayo:
Amalensi omthunzi aguquguqukayo, aziwa nangokuthi amalensi omthunzi alungisekayo, avumela abashiseli ukuthi balungise ubumnyama mathupha ngokuya ngezidingo ezithile zokushisela. Lawa ma-lens ahlinzeka ngokuhlukahlukana kwabashiseli abenza imisebenzi yokukhanya okuhlukile kokushisela kanye nezindlela zokushisela.
3) Umbala Wangempela:
Ubuchwepheshe boMbala Weqiniso benza ukukhanya kubonakale kakhudlwana ngesihlungi, ngesikhathi esifanayo vimba imisebe eyingozi ye-UV/IR, bunikeze i-welder umbono wokucaca okuphezulu.
4. Thola Izihlungi Ezithembekile Zokushisela:
1) Ukuhambisana namazinga okuphepha:
Lapho ukhetha isihlungi sokushisela, kubalulekile ukuqinisekisa ukuthi sithobela izindinganiso zokuphepha ezibekwe yizindikimba ezifanele ezilawulayo, njenge-CE, ANSI, CSA, AS/NZS...
2) Ukucaca okubonakalayo kanye nesikhathi sokushintsha:
Izihlungi zokushisela zekhwalithi ephezulu zinikeza ukucaca okukhethekile okubonakalayo, okuvumela abashiseli ukuthi babone umsebenzi wabo ngokunemba. Ukwengeza, isikhathi sokushintsha ngokushesha (imvamisa esingaphansi kuka-1/20,000 wesekhondi) sibalulekile ukuze kuvikelwe amehlo omshiseli ekukhanyeni okungazelelwe.
3) Izilawuli ezinobungane zomsebenzisi nemisebenzi:
Izihlungi zifakwe izilawuli ezisebenziseka kalula, njengezinkinobho ezinkulu noma isixhumi esibonakalayo esizwela ukuthinta, okuthuthukisa ukusetshenziswa kalula kanye nokulungiswa ngesikhathi semisebenzi yokushisela. Izici ezengeziwe ezifana nokulawula ukuzwela, izindlela zokugaya nezilungiselelo zokulibaziseka zithuthukisa amakhono esihlungi sokushisela.
Ekuphetheni
Ngokuhlanganisa ubuchwepheshe bokwenza ubumnyama ngokuzenzakalela, lezi zihlungi zithuthukisa kakhulu ukuphepha nokusebenza kahle kwe-welding, ukwandisa ukukhiqiza nokunciphisa ukulimala. Ukuze unqume isihlungi esithembekile sokushisela, ukuthobela izindinganiso zokuphepha, ukucaca okuhle kakhulu kokubona, isikhathi sokushintsha ngokushesha, ukuqina, nezici ezisebenziseka kalula yizici ezibalulekile okufanele zicatshangelwe. Ngokuthuthuka okuqhubekayo kubuchwepheshe besihlungi sokushisela, abashiseli sebengakwazi ukusebenza endaweni ephephile nenethezeke kakhudlwana, beqinisekisa impilo yabo yesikhathi eside nenhlalakahle yamehlo.
