Aiki na kariya gas a Laser waldi tsari
(1) Gas mai karewa na iya kare ruwan tabarau na Laser daga gurɓataccen tururi da zubar da ruwa.
(2) Turin ƙarfe yana ɗaukar katako na Laser kuma yana yin ionizes zuwa gajimare na plasma. Idan plasma ya yi yawa, ƙwayar Laser tana cinye ta plasma zuwa ɗan lokaci. Gas ɗin kariya na iya tarwatsa tururin ƙarfe na ƙarfe ko gizagizai na plasma, rage tasirin kariya na Laser, da haɓaka ƙimar amfani da Laser mai inganci.
(3) Gas mai karewa na iya kare narkakkar tafkin. Lokacin da aka haɗa wasu kayan, ana iya yin watsi da iskar shaka. Hakanan ana iya yin watsi da kariyar. Duk da haka, ga mafi yawan aikace-aikace, helium, argon, nitrogen da sauran iskar gas sau da yawa amfani da kariya, sabõda haka, workpiece iya zama Guji hadawan abu da iskar shaka a lokacin walda.
Commonly kariya gas ga Laser waldi
(1) Helium: high ionization makamashi, low ionization digiri a karkashin mataki na Laser, iya da sarrafa samuwar plasma girgije, kuma yana da low aiki, m ba chemically amsa da karfe, shi ne mai matukar manufa m gas. Koyaya, farashin helium ya yi yawa kuma galibi ana amfani dashi don binciken kimiyya.
(2) Argon gas: Ƙarfin ionization yana da ƙananan ƙananan, kuma digiri na ionization yana da girma a ƙarƙashin aikin laser, wanda ba shi da amfani don sarrafa samuwar girgije na plasma, kuma zai sami wani tasiri akan ingantaccen amfani da Laser; amma ayyukansa ba su da yawa, wanda ke da wuya a kwatanta shi da na kowa Ƙarfe yana jure wa sinadarai, kuma farashin ba shi da yawa, don haka ana iya amfani da shi azaman iskar kariya ta al'ada. .
(3) Nitrogen: matsakaicin ƙarfin ionization, sama da argon kuma ƙasa da helium. Nitrogen zai iya amsawa ta hanyar sinadarai tare da aluminum gami da carbon karfe a wani zafin jiki don samar da nitrides, wanda zai kara raguwa na walda, rage taurin, kuma zai yi mummunar tasiri a kan kayan aikin injiniya na haɗin gwiwa. Don haka, ba a ba da shawarar yin amfani da nitrogen ba. Aluminum gami da carbon karfe welds ana kiyaye su. Nitride da aka samar ta hanyar sinadarai tsakanin nitrogen da bakin karfe na iya ƙara ƙarfin haɗin gwiwar walda, wanda zai taimaka inganta kayan aikin walda. Don haka, ana iya amfani da nitrogen a matsayin iskar garkuwa lokacin walda bakin karfe.
Hanyar kariya ta iskar gas
A halin yanzu akwai manyan hanyoyi guda biyu don hura gas mai kariya:
(1) Ita ce kariya ta gefe-busa ta gefen gefen
(2) Kariyar coaxial ce, kamar yadda aka nuna a cikin hoton da ke ƙasa.
Gas ɗin kariya da aka hura ba kawai yana buƙatar kare tafkin walda a kan kari ba, har ma yana buƙatar kare daidaitaccen yanki mai ƙarfi wanda aka yi wa walda. Sabili da haka, ana amfani da kariya ta gefe-shaft na gefe gabaɗaya, saboda wannan hanyar kariyar tana da ɗanɗano Yanayin kariya na hanyar kariyar coaxial ya fi fadi, musamman ga yankin da walda ya daɗe.
Busa gefen gefen gefe Don aikace-aikacen injiniya, ba duk samfuran ba ne za a iya kiyaye su ta hanyar busa gefen shaft. Ga wasu takamaiman samfura, kawai kariya ta coaxial za a iya amfani da. Yana buƙatar a yi niyya daga tsarin samfurin da nau'in haɗin gwiwa. Zaɓin jima'i.
Domin siffar weld ɗin madaidaiciya, nau'in haɗin gwiwa na iya zama haɗin gwiwa na gindi, haɗin gwiwa na cinya, haɗin gwiwa na kusurwa ko haɗa haɗin haɗin gwiwa. Irin wannan samfurin yana ɗaukar hanyar kariya ta gefen-busa.
Don samfurori waɗanda siffar weld ɗin ke da madauwari ko polygonal, kuma nau'ikan haɗin gwiwa sune haɗin gwiwar gindi, haɗin gwiwar cinya, haɗin gwiwar walda, da sauransu, yana da kyau a yi amfani da kariyar coaxial don irin wannan samfurin.
Abin da ke sama shine aiki da hanyar karewa na iskar gas na walda laser. A cikin ainihin tsarin amfani, ya kamata a zaba bisa ga ainihin halin da ake ciki.
