Lisefe tsa ho fifatsa li-welding li emela katleho e kholo polokehong ea indasteri, tsoelopele e kholo e netefatsang tšireletso e phahameng ea mahlo a batho ba chesellang. Ka tlhokahalo e ntseng e eketseha ea mekhoa e metle ea li-welding ho pholletsa le liindasteri, nts'etsopele ea li-filters tsa welding e fetohile ea bohlokoa. Sengoliloeng sena se fana ka pono e tebileng ea hore na li-filters tsa weld li sebetsa joang, nalane ea eona, theknoloji e fumanehang, le mokhoa oa ho khetha sefe e tšepahalang ea ho cheselletsa.
1. Molao-motheo oa ts'ebetso oa filthara ea welding:
Li-filters tsa welding, tse tsejoang hape e le lihelmete tsa welding, li sebetsa ho latela molao-motheo oa ho sefa optical le shading. Kaha li na le lisebelisoa tsa motlakase le tsa mochini, lihloela tsena li sireletsa mahlo a batho ba chesehelang mahlaseli a kotsi a ultraviolet (UV) le a infrared (IR). Ka ho sebelisa theknoloji ea ho fifala ka mokhoa o itekanetseng, mochini oa welding o khona ho fetola boemo ba shading ka mokhoa o feto-fetohang ho latela ts'ebetso ea welding ho netefatsa hore welder e ka fumana pono e ntle ka ho fetisisa.
Karolo e ka sehloohong e ikarabellang bakeng sa ho lokisa ponahalo ke Liquid Crystal e ka hare ho sefe. Kristale ena ea metsi e khona ho fetola ponahalo ea eona ho latela matla a arc ea welding e hlahisoang nakong ea ts'ebetso ea welding. Li-sensor tsa Arc li lula li lekola ts'ebetso ea welding 'me li romela lets'oao ho LC ho lokisa moriti o lefifi, ebe li fana ka tšireletso e phahameng bakeng sa mahlo a welder.
2. Nalane ea nts'etsopele ea filthara ea welding:
Nalane ea li-filters tsa welding e qalile mathoasong a lilemo tsa bo-1940, ha welding ea arc e qala ho sebelisoa haholo. Qalong, limaske tse cheselletsang li ne li e-na le lilense tse sa fetoheng tse neng li fana ka tšireletso e fokolang ea UV le IR. Lilense tsena tse tala ha lia ka tsa fana ka phetoho e nepahetseng ea moriti kapa tšireletso e tsitsitseng, e bakang likotsi tse ngata tsa mahlo har'a li-welders.
Ha nako e ntse e ea, tlhokahalo ea litekanyetso tse ntlafetseng tsa tšireletso e ile ea susumelletsa ho ntlafatsoa ha li-filters tse fapaneng tsa li-welding. Lilemong tsa bo-1980, ho ile ha hlaha li-filters tsa elektronike, tse kopanyang li-arc le liphanele tsa LCD. Lintlafatso tsena li fetotse indasteri ea li-welding kaha li-filters tsena li thusa ho ikamahanya le moriti o ikemetseng, ho netefatsa polokeho le ponahalo e eketsehileng.
3. Theknoloji e teng ea filthara ea welding:
1) Sefe ea ho fifala ka boits'oaro (ADF):
Theknoloji e tsebahalang ka ho fetesisa ea li-filters tsa sejoale-joale ke ADF, e sebelisang motsoako oa li-sensor le tokiso e ikemetseng ho fana ka tšireletso e ke keng ea lekanngoa ea mahlo. E tsamaisoa ke libeteri le liphanele tsa letsatsi, li-filters tsena li na le kutloelo-bohloko haholo ho arc ea welding 'me li ka fetola moriti o lefifi ka nako e ka tlase ho motsotsoana.
2) Lense ea moriti o feto-fetohang:
Lilense tse feto-fetohang tsa moriti, tse tsejoang hape e le lilense tse feto-fetohang tsa moriti, li lumella li-welders ho fetola lefifi ho latela litlhoko tse khethehileng tsa welding. Lilense tsena li fana ka maemo a fapaneng bakeng sa li-welders tse etsang mesebetsi ea mabone a fapaneng a matla le mekhoa ea ho cheselletsa.
3) Mmala oa 'Nete:
Theknoloji ea 'Mala oa' Nete e etsa hore khanya e bonahale haholoanyane ka sefe, ka nako e ts'oanang e thibela mahlaseli a kotsi a UV/IR, e fana ka pono e hlakileng ea welder.
4. Khetholla Lisefe tse Tšepahalang tsa Weld:
1) Ho lumellana le litekanyetso tsa polokeho:
Ha u khetha filthara ea li-welding, ho bohlokoa ho netefatsa hore e lumellana le litekanyetso tsa polokeho tse behiloeng ke mekhatlo e laolang e amehang, joalo ka CE, ANSI, CSA, AS/NZS...
2) Ho hlaka ha Optical le nako ea ho fetola:
Li-filters tsa boleng bo holimo li fana ka khanya e ikhethang ea optical, e lumellang li-welders ho bona mosebetsi oa tsona ka nepo. Ho feta moo, nako ea ho chencha ka potlako (hangata e ka tlase ho 1/20,000 ea motsotsoana) e bohlokoa ho sireletsa mahlo a motho ea chesehelang mahlaseling a tšohanyetso.
3) Litaolo le mesebetsi e bonolo ea basebelisi:
Li-filters li na le li-control tse bonolo tsa basebelisi, joalo ka likonopo tse kholo kapa sebopeho se sa utloeng letho, se ntlafatsang ts'ebeliso le tokiso nakong ea ts'ebetso ea welding. Likarolo tse ling tse joalo ka taolo ea kutlo, mekhoa ea ho sila le litlhophiso tsa ho lieha ho eketsa bokhoni ba sefahla sa welding.
Ha re phethela
Ka ho kenyelletsa theknoloji ea ho fifatsa ka boits'oaro, li-filters tsena li ntlafatsa haholo ts'ireletso le ts'ebetso ea welding, li eketsa tlhahiso le ho fokotsa likotsi. Ho tseba hore na filthara e ka tšeptjoang ea tjheseletsa, ho latela litekanyetso tsa polokeho, ho hlaka ho hoholo ha pono, nako ea ho fetoha ka potlako, ho tšoarella, le likarolo tse bonolo tsa basebelisi ke lintlha tsa bohlokoa tse lokelang ho nahanoa. Ka tsoelo-pele e tsoelang pele ea theknoloji ea li-welding filter, li-welders joale li ka sebetsa sebakeng se sireletsehileng le se phutholohileng haholoanyane, ho netefatsa bophelo ba bona ba nako e telele le bophelo bo botle.
