Litaba - Litšebeliso tse ka sehloohong tsa lasers indastering

Ho tloha ha e qala ka bo-1960, theknoloji ea laser e ntlafetse ka potlako ho ba sesebelisoa sa bohlokoa lefapheng la tlhahiso ea indasteri ka lebaka la matla a eona a mangata, tataiso e ntle le taolo. Ha e bapisoa le mekhoa ea setso ea ts'ebetso ea mechini, ts'ebetso ea laser e na le melemo e meholo joalo ka ho se kopane, ho nepahala ho hoholo le boemo bo phahameng ba boiketsetso, 'me e sebelisoa haholo tlhahisong ea indasteri joalo ka ho seha thepa, ho tjheseletsa, ho tšoaea, ho cheka le tlhahiso ea litlatsetso. Ho ea ka mofuta oa laser le litšobotsi tsa eona tsa ts'ebetso, ts'ebetso ea laser ea indasteri e arotsoe haholo ka mekhahlelo e meraro: ho seha laser, ho tjheseletsa laser le tlhahiso ea litlatsetso ea laser. Mokhoa o mong le o mong oa ts'ebetso o na le mokhoa oa oona o ikhethang oa ts'ebetso le boholo ba ts'ebeliso.

Ho itšeha ka laser

Ho seha ka laser ke e 'ngoe ea lits'ebetso tsa laser ea indasteri tse hōlileng ka ho fetisisa. E sebelisa lebone la laser le matla a maholo ho qhibilihisa le ho etsa hore thepa e be mouoane, 'me e kopantsoe le khase e thusang ho foka slag, ho fihlela ho seha ho sebetsang hantle le ho nepahetseng. Li-laser tsa CO₂ le li-laser tsa fiber hajoale ke lisebelisoa tse ka sehloohong, tse loketseng ho seha lipoleiti tse mahareng le tse tšesaane tsa thepa e kang tšepe ea carbon, tšepe e sa hloekang le motsoako oa aluminium. Melemo ea theknoloji ena e lutse lekhalong la eona le lesesaane, sebaka se senyenyane se amehileng ke mocheso, ha ho hlokahale hlobo le bokhoni ba ho fetola litsela tsa ts'ebetso kapele. E loketse haholo liindasteri tse batloang haholo joalo ka tlhahiso ea likoloi, ts'ebetso ea tšepe ea lakane le sefofane.

Tlhahisong ea likoloi, ho seha ka laser ho sebelisoa ho hlahisa likarolo tse fapaneng ho tloha ho liphanele tsa 'mele ho ea ho lienjine. Mohlala, li-laser tsa fiber li sebelisoa bakeng sa ho seha likarolo tsa tšepe tse matla haholo ka nepo, ka hona ho finyella ho bobebe ha likoloi.

(2) Indasteri ea lifofane e boetse e rua molemo theknolojing ea ho seha ka laser, haholo-holo tlhahisong ea likarolo tse rarahaneng tse entsoeng ka thepa e tsoetseng pele joalo ka titanium le thepa e kopaneng. Mohlala, li-laser tse potlakileng haholo li ka sebelisoa ho seha likarolo tsa motsoako oa titanium tse nang le libopeho tse rarahaneng, ha ka nako e ts'oanang li fokotsa tšenyo ea mocheso le ho netefatsa botšepehi ba sebopeho sa likarolo, e leng se ntlafatsang haholo ts'ebetso le polokeho ea likarolo tsa lifofane.

Ho tjheseletsa ka laser

Ho tjheseletsa ka laser ho fihlella kgokelo ka ho qhibilihisa thepa ya tshepe ka potlako ka lehlasedi la laser, le nang le ho kenella ho tebileng, lebelo le phahameng, le ho kenya mocheso o tlase. Mekhoa e tlwaelehileng ya ho tjheseletsa e kenyelletsa ho tjheseletsa ka laser e tswelang pele le ho tjheseletsa ka laser e pulsed, e loketseng ho tjheseletsa ka nepo ya poleiti e tshesane le maemo a ho tjheseletsa ka botebo. Ha ho bapiswa le ho tjheseletsa ka arc, di-seam tsa ho tjheseletsa ka laser di na le matla a hodimo le ho fetoha ho fokolang, mme di sebetsa masimong a kang ho paka betri, ho tjheseletsa dikarolo tsa tshepe e sa ruseng, le tlhahiso ya dikarolo tsa meaho ya matla a nyutlelie. Haholo-holo tlhahisong ya betri, ho tjheseletsa ka laser e se e le mokgwa o ka sehloohong wa kgokelo.

(1) Indastering ea likoloi, ho tjheseletsa ka laser ho sebelisoa ho hokahanya liphanele tsa 'mele, likarolo tsa enjene le likarolo tse ling tsa bohlokoa. Mohlala, li-laser tsa fiber li sebelisoa bakeng sa ho tjheseletsa ka nepo likarolo tsa tšepe tse matla ho theha manonyeletso a matla le a tšoarellang.

(2) Indastering ea lisebelisoa tsa elektroniki, ho tjheseletsa ka laser ho sebelisoa bakeng sa khokahano e nepahetseng haholo ea likarolo tse nyane le tse nepahetseng. Mohlala, li-laser tsa diode li sebelisoa ho tjheseletsa lisele tsa betri libetering tsa lithium-ion ho netefatsa botšepehi ba likhokahano tsa motlakase.

(3) Indastering ea lifofane, Boeing 787 Dreamliner e sebelisa theknoloji ea ho tjheseletsa ka laser ho hokahanya li-alloy tsa titanium le thepa e kopaneng, e fokotsa palo ea li-rivets haholo, e theola boima ba fuselage, le ho ntlafatsa ts'ebeliso e ntle ea mafura.

Theknoloji ea laser, e le tšiea ea bohlokoa ea tlhahiso e tsoetseng pele, e ntse e atolosa meeli ea eona ea ts'ebeliso ea indasteri khafetsa. Hona joale, ts'ebetso ea laser e ntse e tsoela pele ho ea ho matla a phahameng, ho nepahala ho phahameng le litaelo tsa kopanyo ea lits'ebetso tse ngata, joalo ka ho welding ea arc composite ea laser-electric, laser ultrafast micro-processing, le litsamaiso tsa tlhokomelo tse bohlale tsa laser. Nakong e tlang, ka tsoelo-pele e tsoelang pele ea li-lasers tsa semiconductor tse matla a phahameng, litsamaiso tsa taolo tse bohlale, le likhopolo tsa tlhahiso e tala, ts'ebetso ea laser e tla tsoela pele ho bapala karolo ea bohlokoa tlhahisong e bohlale, lihlahisoa tse ikhethileng, le masimo a ts'ebetso e feteletseng ea thepa.
