Nrog rau kev siv cov hlau tsis-ferrous ntau ntxiv, nws cov cuab yeej sib txuas tau nyiam ntau thiab ntau dua. Kev lag luam ntshiab nickel muaj kev tiv thaiv corrosion zoo heev. Hauv kev tsim khoom, cov nickel ntshiab yog tsuas yog siv los ua cov hlau tsis muaj steel thiab lwm yam corrosion-resistant alloys, thiab tseem tuaj yeem siv los ua cov tshuaj tiv thaiv hydrogenation, nrog rau kev tsim cov khoom siv ceramic, hluav taws xob circuits, iav ntsuab thiab Ni compounds. Aluminium muaj tsawg dua, kev ua kom zoo, thermal corrosion thiab hluav taws xob conductivity thiab tseem tuaj yeem tau txais kev txaus siab cov khoom siv ntawm cov kub tsawg heev. Nws tau siv dav hauv kev lag luam tshuaj, tshuab, tsheb thauj mus los, kev tsim kho, aerospace thiab kev tsim khoom txhua hnub thiab lub neej. Cov txheej txheem vuam tsoos (xws li MIG, TIG, thiab lwm yam) vuam xws li cov hlau, tab sis lub zog sib koom ua ke tsis txaus, thiab cov vuam yog yooj yim los tsim cov pa roj, slag suav nrog, tawg thiab lwm yam tsis xws luag, thiab lub xeev ntawm cov hlau welded muaj. ib qho kev cuam tshuam zoo heev rau kev vuam zoo. Lub vuam yog qhov yooj yim rau vuam deformation thiab porosity, qhov seem ntawm kev ntxhov siab yog loj, thiab nws yog rhiab heev rau kev ntxhov siab corrosion, uas tsis tuaj yeem muab tag nrho cov khoom ntawm cov khoom. Yog li ntawd, nws yog ib qho tsim nyog thiab ceev nrooj los tshawb nrhiav kev siv cov txheej txheem vuam tshiab hauv cov khoom siv nickel thiab txhuas.
1. Kev cuam tshuam ntawm vuam tsis nyob rau saum npoo ntawm welded pob qij txha
Nyob rau hauv lub aluminium - nickel laser vuam xeem, cov vuam tsis cuam tshuam feem ntau muaj xws li laser zaus, laser zog thiab vuam ceev. Vim tias lawv cov teebmeem sib txawv ntawm kev sib koom ua ke, qib ntawm kev cuam tshuam ntawm kev sib koom ua ke kuj txawv. Raws li cov ntaub ntawv tshuaj xyuas thiab ib feem ntawm cov kev tshawb fawb soj ntsuam, thaum lub laser zaus yog 200Hz, cov nyhuv vuam yog qhov zoo tshaj plaws, thiab cov cua kub me me tuaj yeem lav tau.
1.1 Kev cuam tshuam ntawm lub zog laser rau saum npoo ntawm kev sib koom ua ke
Thaum lub zog laser me me, tag nrho cov deformation ntawm cov qauv welded me me, tsis muaj qhov pom tseeb porosity thiab tawg ntawm qhov chaw vuam, tsis muaj qhov pom tseeb tshwm sim tawg thiab tom, thiab muaj kev ntxhib los mos. Nyob rau hauv cov ntaub ntawv ntawm qhov tsis tu ncua welding ceev, qhov vuam dav ntawm lub hauv ntej yuav nce nrog qhov nce ntawm lub zog laser. Thaum lub zog laser tsawg dua 1.8kW, qhov chaw vuam qhov chaw muaj kev nyuaj siab, thiab qhov tshwm sim oxidation tsis pom tseeb. Thaum lub zog laser yog 2.0kW, qhov vuam tau tsim tau zoo thiab qhov tshwm sim oxidation tsis pom tseeb. Thaum lub zog laser yog 2.2kW, qhov vuam yog tsim tau zoo, qhov saum npoo yog du thiab zoo nkauj, thiab kev ntxhib los mos yog qhov tseeb. Thaum lub zog laser yog 2.4kW, qhov vuam yog tsim tau zoo dua, qhov oxidation nto yog qhov hnyav dua, thiab sab nraub qaum tsuas yog welded los ntawm. Thaum lub zog laser yog 2.6kW, lub vuam yog welded tag nrho, lub pas dej molten hlau dov, qhia dub, thiab oxidation yog heev loj.
1.2 Kev cuam tshuam ntawm vuam ceev ntawm qhov chaw tsim ntawm welded sib koom
Nyob rau hauv cov ntaub ntawv ntawm lub zog laser tas li, nrog rau qhov qeeb ntawm qhov vuam ceev, qhov dav ntawm qhov vuam qhia tau tias muaj kev nce ntxiv. Thaum lub vuam ceev yog 50mm / s, qhov sib koom ua ke melting dav me me thiab muaj kev nyuaj siab nyob rau hauv nruab nrab ntawm lub vuam. Thaum vuam ceev yog 40mm / s, lub vuam yog zoo melted thiab tsim, nto yog du thiab zoo nkauj, thiab kev ntxhib los mos yog ntshiab. Thaum lub vuam ceev yog 30mm / s, qhov dav dav dav dav dua thiab qhov oxidation nto yog qhov hnyav. Thaum lub vuam ceev yog 20mm / s, qhov vuam oxidation yog qhov hnyav heev, lub vuam pib tsim kom pom tseeb deformation, vuam yog distorted, thiab sab nraub qaum tau welded los ntawm.
2. Kev cuam tshuam ntawm laser vuam tsis nyob rau hauv qhov tob thiab dav
Lub vuam zoo ntawm aluminium-nickel lap welded qauv nyob ntawm tsis yog tsuas yog nyob rau hauv cov khoom ntawm kev sib koom tes, tab sis kuj nyob rau hauv lub vuam txoj kev thiab oxidation discoloration. Qhov tob thiab dav ntawm weld yog qhov tseem ceeb rau kev ntsuas qhov saum npoo, qhov degree ntawm oxidation thiab discoloration ntawm sab nraub qaum thiab cov khoom siv ntawm cov khoom sib koom ua ke. Lub weld qhov tob feem ntau cuam tshuam rau qhov zoo ntawm qhov vuam rov qab, thaum lub vuam dav feem ntau cuam tshuam rau cov khoom siv sib txuas. Laser vuam tsis (laser zog, vuam ceev) yog ib yam tseem ceeb uas cuam tshuam rau vuam zoo. Hauv qhov kev sim no, kev cuam tshuam ntawm lub zog laser thiab vuam ceev ntawm qhov tob ntawm vuam, vuam dav, microstructure thiab tensile zog ntawm stainless hlau taub qab sib koom tau kawm, uas tau muab qhov tsim nyog theoretical hauv paus rau kev ua kom zoo ntawm laser vuam tsis ntawm aluminium-nickel lap joint. hauv kev tsim khoom tiag.
2.1 Kev cuam tshuam ntawm lub zog laser ntawm qhov tob tob thiab dav
Lub weld qhov tob thiab dav yog cuam tshuam zoo heev los ntawm lub zog laser, thaum qhov seem qhov siab ntawm qhov vuam qhia tsis muaj qhov tsis tu ncua, uas tej zaum yuav tshwm sim los ntawm cov kev taw qhia ntawm kev tiv thaiv roj nyob rau hauv qee qhov kev txwv. Thaum lub zog laser me me (1.8kW), cov ntawv hlau stainless tsuas yog me me ntawm cov yaj, thiab cov vuam nkag yog me me thiab qhov dav melting yog nqaim. Nrog rau qhov nce ntawm lub zog laser, qhov tob tob thiab qhov dav tau nce ntxiv, thaum lub zog laser nce mus txog 2.4kW, lub vuam tsuas yog nkag mus, thiab nrog lub zog laser nce ntxiv, qhov dav nkag mus txuas ntxiv mus, thiab rov qab vuam yog. kuj nthuav dav.
2.2 Kev cuam tshuam ntawm vuam ceev ntawm qhov tob tob thiab dav
Nrog kev txo qis ntawm vuam ceev, qhov tob tob thiab qhov dav nce ntxiv, thaum lub vuam ceev tsuas yog 30mm / s, lub vuam yuav tsum tau nkag mus rau tag nrho, thiab nrog lub zog laser nce ntxiv, qhov dav nkag mus ntxiv mus ntxiv, thiab lub nraub qaum weld tseem nkag mus thiab nthuav dav.
3. Cov lus xaus
3.1 Thaum lub hwj chim nce, lub laser cua sov input nce, lub melting npaum li cas ntawm cov welded hlau cov ntaub ntawv yuav nce, thiab qhov luaj li cas ntawm weld pas dej ua ke yuav nce raws li, yog li ua rau lub weld dav. Qhov ceev ntawm vuam ceev, qhov ceev ntawm lub laser beam txav nyob rau saum npoo ntawm cov qauv, lub zog input nyob rau hauv lub weld ib chav tsev lub sij hawm thiab chav tsev ntev yog txo, lub laser vuam kub input yog txo, thiab melting tus nqi ntawm welded kub. cov khoom raug txo, kom qhov dav ntawm weld ua me.
3.2 Nyob rau hauv aluminium-nickel laser welded sib koom, thaum lub zog laser qis los yog vuam ceev yog siab, lub hauv paus hlau melting npaum li cas ntawm aluminium-nickel sib txuas yog tsawg, thiab melting dav thiab deformation ntawm aluminium-nickel sib koom. me me. Thaum lub zog laser nce los yog qhov vuam ceev txo qis, lub melting nqi ntawm lub hauv paus hlau nce thiab melting dav ntawm weld nce.
