Kuwiritsa kwa laser kumawoneka makamaka kosintha bwino kwa bwino komanso kuchuluka kwa zida zowonda ndi magawo. Lero sitilankhula za zabwino za laser yotchedwa laseling koma yang'anani momwe mungagwiritsire ntchito mpweya wotchinga wa laser moyenera.
Chifukwa chiyani amagwiritsa ntchito mafuta ogulitsira kwa laser?
Mu laser yowuzidwa, mafuta otchingira adzakhudza momwe mawolodwe amapangidwira, otayika, owala, ndi mliriwu ukulu. Nthawi zambiri, kuwomba mpweya wothandizidwayo kudzathandiza kwambiri weld, koma kungabweretsenso zovuta.
Mukaliza mpweya wopukutira bwino, zikuthandizani:
✦Tetezani dziwe lowonera kuti muchepetse kapena pewani maxidation
✦Kuchepetsa bwino splash zopangidwa munjira yotentha
✦Kuchepetsa bwino ma pores
✦Kuthandiza dziwe lowola limafalikira mogwirizana mukakhazikika, kotero kuti msoko wa weld umabwera ndi chodetsa
✦Zotsatira zoyipa za zitsulo za zitsulo kapena mtambo wa plasma pa laser zikuchepetsedwa, ndipo kuchuluka kwa laser kumachulukitsidwa.
Malingana ngatiMtundu wamafuta wamagesi, mpweya wowonda, ndi kuwomba mafomundi zolondola, mutha kupeza zotsatira zabwino zowotcherera. Komabe, kugwiritsa ntchito molakwika mpweya woteteza kumathanso kusokoneza kuwotcherera. Kugwiritsa ntchito mtundu wolakwika wamafuta amatha kubweretsa zotupa mu zokongoletsera kapena kuchepetsa mphamvu zamatsenga. Zokwera kwambiri kapena zotsika kwambiri zoyenda mpweya zimatha kuyambitsa makuti oxidation ochulukirapo komanso kulowerera kwakukulu kwa zitsulo mkati mwa dziwe lazitsulo, zomwe zimapangitsa kugwa kapena mawonekedwe osagwirizana.
Mitundu ya Shield mpweya
The mankhwala oteteza a laser otchedwa n2, ar, ndi iye. Mphamvu zawo zakuthupi ndi mankhwala ndizosiyana, motero zotsatira zake zomwe zimachitika pamadzimawo ndizosiyananso.
Nitrogen (n2)
Mphamvu yamagetsi ya N2 imakhala yopamwamba kwambiri kuposa iri, komanso yotsika kuposa iyo. Pansi pa radiation ya laser, digiri ya N2 imakhala pa kil, yomwe imatha kuchepetsa mapangidwe a cusma ndikuwonjezera kugwiritsidwa ntchito kothandiza kwa laser. Nitrogen amatha kuchita ndi aluminiyamu sloy ndi chitsulo cha kaboni pamtunda wina kuti apange nitrides, chomwe chingapangitse kulimbitsa thupi ndikuchepetsa mphamvu yayikulu pamakina ogwirira ntchito. Chifukwa chake, posalimbikitsidwa kugwiritsa ntchito nayitrogeni mukamacheza aluminiyamu chiloya ndi chitsulo cha kaboni.
Komabe, mankhwala pakati pa nayitrogeni ndi chitsulo chosapanga dzimbiri chopangidwa ndi nayitrogeni amatha kusintha mphamvu ya zolumikizana zolumikizana, zomwe zingathandize kukonza makina a udzu, kotero kuwotcha chitsulo chosapanga dzimbiri kumatha kugwiritsa ntchito nayitrogeni ngati mpweya wotchinga.
Argon (AR)
Mphamvu ya mankhwala a Argon ndi yotsika kwambiri, ndipo kuchuluka kwake kwa ionization kumakula pansi pa laser. Kenako, argon, monga mpweya wotchinga, sangathe kuwongolera bwino ma plasma, omwe angachepetse kugwiritsidwa ntchito koyenera kwa laser. Funso likubwera: Kodi Argon munthu wolakwitsa kugwiritsidwa ntchito ngati mpweya wotchinga? Yankho lake silikukhala gart, Argon ndizovuta kuchita ndi zitsulo zambiri, ndi zotsika mtengo kuzigwiritsa ntchito. Kuphatikiza apo, kachulutso wa AR ndikulira, kudzakhala koyenera kumira pansi pa dziwe lotseguka ndipo kumatha kuteteza dziwe la ma weln, kotero Argon angagwiritsidwe ntchito ngati mpweya woteteza.
Afilium (iye)
Mosiyana ndi Argon, helium ali ndi mphamvu zokwanira kununkhira zomwe zimatha kuwongolera mapangidwe a plasma mosavuta. Nthawi yomweyo, helium sachita ndi zitsulo zilizonse. Ndisankho labwino kwambiri kwa woloza laser. Vuto lokhalo ndilo helium ndiyabwino kwambiri. Kwa anzeru omwe amapereka zinthu zachitsulo zopangidwa ndi zitsulo, Helimo akuwonjezera kuchuluka kwakukulu kwa mtengo wopangidwa. Chifukwa chake helium imagwiritsidwa ntchito mu kafukufuku kapena zinthu zomwe zili ndi mtengo wowonjezereka kwambiri.
Kodi Kuwombera Mafuta Otetezedwa?
Choyamba, ziyenera kuwonekeratu kuti otchedwa "oyimbidwa" wa weld ndi dzina lofala lokha, lomwe limangokhala ndi dzina lazomwe zimapangidwa ndi zovulaza, zomwe zimayambitsa kuwonongeka kwa weld . Nthawi zambiri, chitsulo cha weld zitsulo chimagwira mpweya, nayitrogeni, ndi haidrogeni mlengalenga pa kutentha kwina.
Pofuna kupewa kuloza "maxidized" amafunika kuchepetsa kapena kupewa kulumikizana ndi zitsulo zovulaza, zomwe siziri mu chitsulo chokhazikika koma nthawi yayitali zitsulo zosungunuka mpaka Chitsulo chosungunuka dziwe limakhazikika ndipo kutentha kwake kumakhala kozizira mpaka kutentha kwina.
Njira ziwiri zazikulu zowombera mpweya wopumira
▶Wina akuwombera mpweya wa shield kumbali, monga tikuonera Chithunzi 1.
▶Wina ndi njira yowutsa yophukira ya coaxial, monga tikuonera Chithunzi 2.
Chithunzi 1.
Chithunzi 2.
Kusankha mwachindunji kwa njira ziwiri zowomba ndi kuganizila bwino mbali zambiri. Mwambiri, tikulimbikitsidwa kutengera njira yowombera.
Zitsanzo zina za laser
1.
Monga taonera Chithunzi 3, mawonekedwe a malonda a chinthucho ndi ofanana, ndipo mawonekedwe olumikizirana amatha kukhala olumikizana, cholumikizira cholumikizira, kapena cholumikizira cholowera. Kwa mtundu uwu wa malonda, ndibwino kutengera mbali-axis ikuwombera mpweya woteteza monga momwe chithunzi 1.
2. Chithunzi chapafupi kapena malo owala
Monga taonera Chithunzi 4, kuwongoleredwa kwazinthuzo ndi mawonekedwe otsekedwa monga kuzungulira ndege, mawonekedwe a ndege Ndikwabwino kutengera njira yotetezera ya coaxial yoteteza monga momwe chithunzi 2 cha mtundu uwu.
Kusankhidwa kwa mpweya woteteza mwachindunji kumakhudzanso kufalitsa kwabwino, Kuchita bwino, komanso chifukwa cha kusiyanasiyana kwa zinthu zomwe zikuwoneka bwino, kusinthidwa kwa mafuta owumako ndi kovuta kwambiri ndikulowerera. Njira, kuwotcherera malo, komanso zofunikira zam'madzizi. Kudzera mayeso owonera, mutha kusankha mpweya wabwino kwambiri kuti ukwaniritse zotsatira zabwino.
Chidwi ndi laser yowuzidwa komanso yofunitsitsa kuphunzira kusankha mafuta
