Laser Welding ke eng?
Laser tjheseletsa ke mofuta oa ho qhibiliha tjheseletsa, ho sebelisa laser beam e le tjheseletsa mocheso mohloli, molao-motheo oa tjheseletsa ke ka mokhoa o itseng oa ho susumelletsa seaplane mafolofolo, ho etsa resonant cavity oscillation, 'me joale fetola ka susumelletsa mahlaseli beam, ha phala. 'me karolo ea mosebetsi e kopana, matla a kenngoa ke karolo ea mosebetsi, ha mocheso o fihla sebakeng sa ho qhibiliha ha thepa e ka kenngoa.
Ho ea ka mokhoa o ka sehloohong oa letamo la ho tjheseletsa, welding ea laser e na le mekhoa e 'meli ea mantlha ea ho tjheseletsa: ho tjheseletsa ha mocheso le ho kenella ka botebo (keyhole) welding.Mocheso hlahisoang ke mocheso conduction tjheseletsa diffused ho sengoathoana mosebetsi ka ho fetisa mocheso, e le hore holim'a tjheseletsa e qhibiliha, ha ho vaporization lokela ho etsahala, e leng e atisa ho sebelisoa ka tjheseletsa ya dikarolo tlaase-lebelo tšesaane-ish.Cheseletso e tebileng ea fusion e etsa hore thepa e be mouoane ebe e etsa plasma e ngata.Ka lebaka la mocheso o phahameng, ho tla ba le masoba ka pele ho letamo le qhibilihisitsoeng.Welding e tebileng ea ho kenella ke mokhoa o sebelisoang ka ho fetisisa oa laser welding, o ka cheselletsa karolo ea mosebetsi ka botlalo, 'me matla a ho kenya a maholo, a lebisang lebelong la ho tjheseletsa ka potlako.
Mekhoa ea ts'ebetso ho Laser Welding
Ho na le mekhoa e mengata ea ts'ebetso e amang boleng ba laser welding, joalo ka matla a matla, laser pulse waveform, defocusing, lebelo la welding le khetho ea khase e sireletsang e thusang.
Matla a Matla a Laser
Matla a matla ke e 'ngoe ea likarolo tsa bohlokoahali ts'ebetsong ea laser.Ka matla a phahameng a matla, bokaholimo bo ka futhumatsoa ho isa sebakeng se belang ka har'a microsecond, e leng se bakang mouoane o mongata.Ka hona, matla a matla a phahameng a na le molemo bakeng sa mekhoa ea ho tlosa thepa e kang ho cheka, ho khaola le ho ngola.Bakeng sa matla a fokolang a matla, ho nka li-milliseconds tse 'maloa hore mocheso o ka holimo o fihle sebakeng se belang,' me pele bokaholimo bo fetoha mouoane, tlase e fihla sebakeng se qhibilihang, seo ho leng bonolo ho etsa weld e ntle ea ho qhibiliha.Ka hona, ka mokhoa oa ho futhumatsa mocheso oa laser welding, boholo ba matla a matla ke 104-106W / cm2.
Laser Pulse Waveform
Laser pulse waveform ha se parameter ea bohlokoa feela ea ho khetholla ho tlosoa ha thepa ho tloha ho qhibiliha ha thepa, empa hape ke parameter ea bohlokoa ho fumana hore na ke bokae le litšenyehelo tsa lisebelisoa tsa ho sebetsa.Ha lebone le phahameng la laser le thunngoa holim'a thepa, bokaholimo ba thepa bo tla ba le 60 ~ 90% ea matla a laser a bonts'itsoeng mme a nkuoe tahlehelo, haholo khauta, silevera, koporo, aluminium, titanium le lisebelisoa tse ling ponahatso e matla le ho fetisa mocheso ka potlako.Ponahatso ea tšepe e fapana ho ea ka nako nakong ea sekhahla sa laser.Ha mocheso oa holim'a thepa o nyolohela sebakeng sa ho qhibiliha, ho bonahatsa ho fokotseha ka potlako, 'me ha bokaholimo bo le boemong ba ho qhibiliha, ho bonahatsa ho tsitsisa ka boleng bo itseng.
Laser Pulse Width
Pulse bophara ke parameter ea bohlokoa ea pulsed laser welding.Bophara ba pulse bo ile ba khethoa ke botebo ba ho kenella le sebaka se amehileng ke mocheso.Ha bophara ba pulse bo ne bo le telele, sebaka se seholo se amehileng ke mocheso, 'me botebo ba ho kenella bo ile ba eketseha ka matla a 1/2 a bophara ba pulse.Leha ho le joalo, ho eketseha ha pulse bophara tla fokotsa tlhōrō matla, kahoo, keketseho ea pulse bophara e sebediswa ka kakaretso bakeng sa mocheso conduction tjheseletsa, ho fella ka ka bophara le sa tebang tjheseletsa boholo, haholo-holo a loketse bakeng sa lap tjheseletsa ea lipoleiti tšesaane le teteaneng.Leha ho le joalo, matla a tlase a phahameng a fella ka ho kenya mocheso o feteletseng, 'me thepa e' ngoe le e 'ngoe e na le bophara bo nepahetseng ba pulse bo eketsang botebo ba ho kenella.
Defocus Bongata
Ho tjheseletsa ka laser hangata ho hloka tekanyo e itseng ya ho tjheseletsa, hobane matla a matla a setsi sa letheba moo ho tsepamisitsweng laser a phahame haholo, hoo ho leng bonolo ho etsa mouwane ho etsa mekoti.Kabo ea matla a matla a batla a tšoana sefofaneng se seng le se seng hole le laser focus.
Ho na le mekhoa e 'meli ea defocus:
Defocus e ntle le e mpe.Haeba sefofane se shebileng se le ka holim'a workpiece, ke defocus e ntle;ho seng joalo, ke defocus e mpe.Ho ea ka thuto ea thutatekanyo ea optics, ha sebaka se pakeng tsa lifofane tse ntle le tse mpe tsa defocusing le sefofane se cheselletsang se lekana, matla a matla a sefofaneng a lekanang a batla a lekana, empa ha e le hantle, sebopeho sa letamo se entsoeng ka ho qhibilihisoa se fapane.Tabeng ea defocus e mpe, ho kenella ho hoholo ho ka fumanoa, ho amanang le mokhoa oa ho thehoa ha letamo le qhibilihisitsoeng.
Lebelo la Welding
Lebelo la welding le etsa qeto ea boleng ba holim'a welding, botebo ba ho kenella, sebaka se amehileng ke mocheso joalo-joalo.Lebelo la welding le tla ama mocheso oa mocheso ka nako ea yuniti.Haeba lebelo la tjheseletsa le lieha haholo, mocheso o kenang o phahame haholo, o fella ka hore workpiece e chese.Haeba lebelo la ho tjheseletsa le potlakile haholo, mocheso oa mocheso o fokola haholo, o fella ka hore sesebelisoa sa tjheseletsa se sebetse ka mokhoa o sa fellang le se sa phethoang.Ho fokotsa lebelo la welding hangata ho sebelisoa ho ntlafatsa ho kenella.
Khase ea Tšireletso ea Phallo e thusang
Khase ea ts'ireletso ea "Axiliary blow" ke ts'ebetso ea bohlokoa ts'ebetsong ea matla a phahameng a laser welding.Ka lehlakoreng le leng, ho thibela lisebelisoa tsa tšepe ho senya le ho silafatsa seipone se lebisang tlhokomelo;Ka lehlakoreng le leng, ke ho thibela plasma e hlahisoang ts'ebetsong ea welding ho tsepamisa maikutlo haholo le ho thibela laser ho fihla holim'a thepa.Ka mokhoa oa ho tjheseletsa laser, helium, argon, naetrojene le likhase tse ling li atisa ho sebelisoa ho sireletsa letamo le qhibilihisitsoeng, e le ho thibela workpiece ho tloha oxidation ka boenjiniere ba ho tjheseletsa.Lintho tse kang mofuta oa khase e sireletsang, boholo ba phallo ea moea le Angle e fokang li na le tšusumetso e kholo ho liphello tsa welding, 'me mekhoa e fapaneng ea ho fofa le eona e tla ba le tšusumetso e itseng ho boleng ba ho cheselletsa.
