I-Laser Welding ingatholwa yi-laser generator eqhubekayo noma egcwele i-laser. Umgomo weLaser Welding ungahlukaniswa ngokushisa okushisayo kwe-welding kanye ne-laser fungusion ejulile yokufudumala. Ubuningi bamandla abangaphansi kwe-104 ~ 105 w / cm2 ukushisa okushisa ukushisa, ngalesi sikhathi, ukujula kokuncibilika, kanye nejubane le-welding lihamba kancane; Lapho amandla e-Power amakhulu kune-105 ~ 107 w / cm2, indawo yensimbi ikhomba "ku-Keyles" ngaphansi kweseshini yokushisa, enezici zejubane le-welding ejulile kanye nesilinganiso esikhulu sokujula.
Namuhla, sizofaka ikakhulukazi ulwazi lwezinto ezinkulu ezithinta ikhwalithi ye-laser ejulile fusion welding
1. Amandla we-laser
E-laser ejulile fusion welding, amandla we-laser alawule ukujula kokungena kanye nejubane le-welding. Ukujula kwe-Weld kuhlobene ngokuqondile nobunzima be-Beam Power futhi kuwumsebenzi wesigameko se-Beam Power kanye ne-Beam FACAL BAST. Ngokuvamile ukukhuluma, ku-laser ugongolo oluthile lwe-laser, ukujula kokungena kukhuphuka ngokwanda kwamandla e-beam.
2. Ibala elibhekelele
Usayizi we-Beam Spot kungenye yezinto ezibaluleke kakhulu eLaser Welding ngoba inquma ubukhulu bamandla. Kepha ukukala kuyinselelo yama-lasers anamandla amakhulu, yize kunezindlela eziningi ezingaqondile zokulinganisa ezitholakalayo.
Usayizi wokuxineka wendawo yokugxila kwe-Beam ungabalwa ngokuya nge-theory theory, kepha usayizi wangempela wendawo mkhulu kunenani elibaliwe ngenxa yokuboniswa kokugxilwa kokufanele. Indlela elula yokulinganisa yindlela yephrofayili yokushisa ye-ISO, ekala ububanzi bendawo yokugxila kanye nokugcotshwa ngemuva kokushiswa kwephepha elimnyama futhi lingena ngePolypropylene Plate. Le ndlela ngokusebenzisa umkhuba wokulinganisa, amakhosi usayizi wamandla we-laser kanye nesikhathi sokusebenza.
3. Igesi evikelayo
Inqubo ye-laser welding ivame ukusebenzisa amagesi okuvikela (i-helium, i-argen, i-nitrogen) ukuvikela ichibi elibunjiweyo, ukuvikela i-workpiep kusuka ku-oxidation inqubo ye-welding. Isizathu sesibili sokusebenzisa igesi evikela ukuvikela i-lens egxile ekungcolisweni ngama-Metal Vapors futhi uthwebule ngamaconsi awuketshezi. Ikakhulu ku-Waser Laser Welding, i-ejecta iba namandla amakhulu, kuyadingeka ukuvikela ilensi. Umphumela wesithathu wegesi okuvikelayo ukuthi uphumelela kakhulu ekusakazeni i-plasmaving ekhiqizwa yi-laser welding ephezulu. Umphunga wensimbi uthatha ugongolo lwe-laser futhi unamafu efwini le-plasma. Igesi evikelayo ezungeze i-metal vapor nayo i-Ionizes ngenxa yokushisa. Uma kune-plasma eningi kakhulu, ugongolo lwe-laser ngandlela thile kudliwe yi-plasma. Njengamandla wesibili, i-plasma ikhona endaweni esebenzayo, eyenza ukujula kwe-weld ejulile kanye ne-Weld Pool Super.
Ungayikhetha kanjani igesi efanelekile yokuvikelwa?
4. Izinga lokutholwa
Ukufakwa kwe-laser kokuqukethwe kuncike kwezinye izakhiwo ezibalulekile zezinto ezibonakalayo, njengezinga lokufakwa, ukuvezakala, ukuvumelanisa okushisayo, izinga lokushisa lokuncibilika, kanye nokushisa okuncibilikayo, nokushisa okuncibilikayo, nokushisa okuncibilikayo, nokushisa okuncibilikayo, nokushisa okuncibilikayo, nokushisa okuncibilikayo. Phakathi kwazo zonke izici, okubaluleke kakhulu inani lokufakwa.
Kunezici ezimbili ezithinta izinga lokufakwa kwezinto ezibonakalayo ku-laser beam. Owokuqala ukumelana nokumelana kwezinto ezibonakalayo. Kutholakala ukuthi izinga lokufakwa kokuqukethwe kokuqukethwe lilingana nempande yesikwele ye-coefficient enobuntu, kanye nokuphikiswa okusebenzayo kuyahlukahluka ngokushisa. Okwesibili, isimo esingaphezulu (noma sokuqeda) salokho okuqukethwe kunethonya elibalulekile esigabeni sokutholwa kogongolo, olunomthelela omkhulu emphumeleni we-welding.
I-5. Ijubane le-welding
Ijubane le-welding linethonya elikhulu ekujuleni kokungena. Ukukhulisa isivinini kuzokwenza ukujula kokungena kokungena emanzini angasho lutho, kepha kuphansi kakhulu kuzoholela ekuncibilikeni ngokweqile kwezinto zokwakha kanye ne-workpiepe welding. Ngakho-ke, kunobubanzi obufanele be-welding burche for impahla ethile ngamandla athile ama-laser nobukhulu obuthile, kanye nokujula kokungena okuphezulu kungatholwa ngenani lejubane elihambisanayo.
6 ubude obugxile kwelensi yokugxila
Ilensi yokugxila ivame ukufakwa ekhanda lesibhamu se-welding, ngokuvamile, i-63 ~ 254mm (ububanzi 2.5 "~ 10") ubude obugxile kukhethiwe. Ukugxila kusayizi we-SPET kulingana nobude obugxile, ubude obufushane obugxile, buncane indawo. Kodwa-ke, ubude bobude obugxile futhi buthinta ukujula kokugxila, okungukuthi, ukujula kokugxilwa kukhuphuka ngokuvumelanisa nobude obugxile, kepha ubude bokugxila okufushane bungathuthukisa ukuqina kwamandla, kepha ubungako bokugxila Phakathi kwelensi kanye nomsebenzi wokusebenza kumele kugcinwe ngokunembile, futhi ukujula kokungena kungekukhulu. Ngenxa yethonya lama-splashes nemodi ye-laser ngesikhathi se-welding, ukujula okuphelele okufushane kakhulu okusetshenziswa ku-welding yangempela kungu-126mm (ububanzi obunobude obukhulu be-254mm (ububanzi obungu-10) kungakhethwa lapho umthungo ukhulu noma iWeld idinga ukukhuphuka ngokwandisa usayizi wendawo. Kulokhu, amandla aphezulu okukhipha ama-laser (amandla e-Power) ayadingeka ukufeza umphumela wokungena okujulile umgodi we-penetation.
