Nws pib-dub vuam cov ntxaij lim dej sawv cev rau qhov tseem ceeb ntawm kev lag luam kev nyab xeeb, kev nce qib loj uas ua kom muaj kev tiv thaiv siab tshaj plaws rau cov vuam qhov muag. Nrog rau qhov xav tau ntau ntxiv rau kev siv vuam zoo thoob plaws hauv kev lag luam, kev tsim cov vuam lim tau dhau los ua qhov tseem ceeb. Cov kab lus no muab kev saib tob tob txog yuav ua li cas weld filters ua haujlwm, nws yog keeb kwm, muaj cov cuab yeej siv, thiab yuav ua li cas xaiv cov lim vuam txhim khu kev qha.
1. Txoj hauv kev ua haujlwm ntawm vuam lim:
Vuam cov ntxaij lim dej, tseem hu ua welding kaus mom hlau, muaj nuj nqi raws li lub hauv paus ntsiab lus ntawm optical filtering thiab shading. Nruab nrog hluav taws xob thiab tshuab ua haujlwm, cov ntxaij lim dej no tiv thaiv cov vuam qhov muag los ntawm teeb meem ultraviolet (UV) thiab infrared (IR) hluav taws xob. Los ntawm kev siv tshuab tsis siv neeg tsaus nti, lub vuam lim tuaj yeem hloov kho tau yooj yim thiab tuaj yeem kho cov shading qib raws li cov txheej txheem vuam kom ntseeg tau tias cov vuam tuaj yeem tau txais qhov pom zoo tshaj plaws.
Lub luag haujlwm tseem ceeb ntawm kev kho qhov pom kev yog Liquid Crystal uas nyob rau hauv lub lim. Cov kua siv lead ua kua no muaj peev xwm hloov tau nws cov pob tshab raws li qhov siv ntawm cov vuam arc tawm thaum lub sij hawm vuam txheej txheem. Arc sensors tsis tu ncua saib xyuas kev ua haujlwm vuam thiab xa cov teeb liab tam sim rau LC los kho qhov ntxoov ntxoo tsaus, tom qab ntawd muab kev tiv thaiv siab tshaj plaws rau cov vuam qhov muag.
2. Kev txhim kho keeb kwm ntawm vuam lim:
Keeb kwm ntawm vuam lim hnub rov qab mus rau thaum ntxov 1940s, thaum arc vuam siv dav siv. Thaum xub thawj, vuam qhov ncauj qhov ntswg muaj cov tsom iav dub ruaj khov uas muab kev tiv thaiv UV thiab IR txwv. Cov lo ntsiab muag crude no tsis tau muab qhov ntxoov ntxoo meej los yog kev tiv thaiv zoo ib yam, ua rau ntau qhov muag raug mob ntawm cov welders.
Sij hawm dhau mus, qhov xav tau kev txhim kho cov qauv kev nyab xeeb tau ua rau muaj kev txhim kho ntawm cov ntxaij lim dej sib txawv. Hauv xyoo 1980s, cov ntxaij lim dej siv hluav taws xob tau tshwm sim, sib koom ua ke arc sensors thiab LCD panels. Cov kev nce qib no tau hloov pauv kev lag luam vuam vim cov ntxaij lim dej no tuaj yeem hloov kho qhov ntxoov ntxoo tsis siv neeg, ua kom muaj kev nyab xeeb thiab pom kev zoo dua.
3. Kev siv thev naus laus zis ntawm vuam lim:
1) Nws pib tsaus nti lim (ADF):
Cov cuab yeej nrov tshaj plaws hauv cov ntxaij lim dej niaj hnub no yog ADF, uas siv kev sib xyaw ntawm cov sensors thiab tsis siv neeg tint hloov los muab kev tiv thaiv qhov muag tsis sib xws. Tsim los ntawm cov roj teeb thiab cov hnub ci vaj huam sib luag, cov ntxaij lim dej no muaj kev nkag siab zoo rau cov vuam arc thiab tuaj yeem kho qhov ntxoov ntxoo tsaus nti hauv tsawg dua ib pliag.
2) Variable ntxoov ntxoo lens:
Qhov sib txawv ntxoov ntxoo lo ntsiab muag, tseem hu ua adjustable ntxoov ntxoo lo ntsiab muag, tso cai rau welders manually kho qhov tsaus ntuj raws li cov kev cai vuam tshwj xeeb. Cov lo ntsiab muag no muab ntau yam rau cov welders ua cov haujlwm ntawm kev sib txawv ntawm vuam lub teeb thiab cov txheej txheem vuam.
3) Xim Xim:
Muaj tseeb xim tshuab ua kom pom lub teeb pom kev zoo dua los ntawm cov lim dej, tib lub sijhawm thaiv qhov teeb meem UV / IR hluav taws xob, muab welder pom qhov siab.
4. Txheeb xyuas qhov ruaj khov Weld lim:
1) Ua raws li cov qauv kev nyab xeeb:
Thaum xaiv lub vuam lim, nws yog ib qho tseem ceeb kom ntseeg tau tias nws ua raws li cov qauv kev nyab xeeb uas tau teev tseg los ntawm cov koom haum tswj hwm, xws li CE, ANSI, CSA, AS / NZS ...
2) Optical clarity thiab hloov sijhawm:
High-zoo welding lim muab tshwj xeeb kho qhov muag pom tseeb, tso cai rau welders pom lawv cov hauj lwm nrog precision. Tsis tas li ntawd, lub sijhawm hloov pauv ceev (feem ntau tsawg dua 1/20,000 ntawm ib thib ob) yog qhov tseem ceeb los tiv thaiv tus welder lub qhov muag ntawm lub teeb tam sim ntawd.
3) Kev tswj hwm tus phooj ywg thiab kev ua haujlwm:
Cov ntxaij lim dej tau nruab nrog cov neeg siv kev tswj hwm, xws li cov nyees khawm loj lossis kov-sensitive interface, txhim kho kev yooj yim ntawm kev siv thiab kev hloov kho thaum lub sij hawm vuam ua haujlwm. Ntxiv nta xws li kev tswj rhiab heev, kev sib tsoo hom thiab ncua kev teeb tsa ntxiv txhim khu lub peev xwm ntawm lub vuam lim.
Hauv kev xaus
Los ntawm kev sib koom ua ke ntawm kev siv tshuab ua kom tsaus ntuj, cov ntxaij lim dej no txhim kho kev nyab xeeb thiab kev ua haujlwm zoo, ua kom cov khoom tsim tau thiab txo cov kev raug mob. Txhawm rau txiav txim siab lub vuam lim dej txhim khu kev qha, ua raws li cov qauv kev nyab xeeb, pom kev pom tseeb zoo, lub sijhawm hloov pauv ceev, ua haujlwm ntev, thiab cov neeg siv khoom zoo yog qhov tseem ceeb rau kev txiav txim siab. Nrog kev nce qib txuas ntxiv hauv vuam lim tshuab, welders tam sim no tuaj yeem ua haujlwm hauv qhov chaw nyab xeeb thiab zoo dua, ua kom lawv lub qhov muag mus ntev thiab kev noj qab haus huv.
