Iko Kupesvedzera Kwekudzivirira Gasi muLaser Welding
Chii Chinogona Kukutorera Gasi Rokudzivirira Rakanaka?
In laser welding, kusarudzwa kwegasi rekudzivirira kunogona kuve nemhedzisiro yakakosha pakuumbwa, mhando, kudzika, uye hupamhi hweiyo weld seam.
Muzviitiko zvakawanda, kuiswa kwegasi rinodzivirira kune mhedzisiro yakanaka pane weld seam nepo kushandiswa zvisina kunaka kwegasi rinodzivirira kunogona kuve nemhedzisiro inokuvadza pawelding.
Izvo zvakakodzera uye zvisina kunaka mhedzisiro yekushandisa gasi rekudzivirira ndeaya anotevera:
Kushandisa Kwakakodzera
Kusashandisa Kwazvo
1. Kubudirira Kudzivirira kweThe Weld Pool
Kuunzwa kwakaringana kwegasi rinodzivirira kunogona kunyatso dzivirira dziva re weld kubva kune oxidation kana kutodzivirira oxidation zvachose.
1. Kuparara kweThe Weld Seam
Kuunzwa kwakashata kwegasi rinodzivirira kunogona kukonzera kushata weld seam mhando.
2. Kuderedzwa kweSpattering
Kunyatso kuunza gasi redziviriro kunogona kunyatso kudzikisa kupfachura panguva yewelding process.
2. Kutsemuka Uye Kuderedza Mechanical Properties
Kusarudza iyo isiriyo gasi mhando inogona kutungamirira kune weld seam kupaza uye kuderera kwemechanicha kuita.
3. Kuumbwa kwakafanana kweiyo Weld Seam
Kuiswa kwakakodzera kwegasi rinodzivirira kunokurudzira kunyange kupararira kwechidziva che weld panguva yekusimbisa, zvichikonzera yunifomu uye inoyevedza weld seam.
3. Kuwedzera Oxidation Kana Kupindira
Kusarudza iyo isiriyo gasi inoyerera mwero, ingave yakanyanya kana yakaderera, inogona kutungamirira kukuwedzera oxidation ye weld seam. Inogonawo kukonzera kukanganisa kwakanyanya kune yakanyungudutswa simbi, zvichikonzera kudonha kana kusaenzana kuumbwa kwe weld seam.
4. Kuwedzera Laser Kushandiswa
Kunyatso kuunza gasi rekudzivirira kunogona kunyatso kudzikisa kudzivirira kwesimbi vapor plumes kana makore eplasma pane laser, nekudaro kuwedzera kushanda kwelaser.
4. Kusakwana Kudzivirirwa kana Negative Impact
Kusarudza nzira isina kunaka yekusuma gasi inogona kutungamirira mukusakwana kwekudzivirira kwe weld seam kana kunyange kuva nemigumisiro yakaipa pakuumbwa kwe weld seam.
5. Kuderedza Weld Porosity
Kunyatso kuunza gasi rekudzivirira kunogona kunyatso kudzikisa kuumbwa kwegasi pores mu weld seam. Nekusarudza iyo yakafanira gasi rudzi, kuyerera mwero, uye nzira yekusuma, mhedzisiro yakanaka inogona kuwanikwa.
5. Kufurira paWeld Depth
Kuiswa kwegasi rinodzivirira kunogona kuve nekukanganisa kudzika kweiyo weld, kunyanya mutetepa plate welding, uko kunoda kuderedza kudzika kweweld.
Mhando dzakasiyana dzeDziviriro Gasi
Magasi ekudzivirira anowanzo shandiswa mulaser welding initrogen (N2), argon (Ar), uye helium (He). Aya magasi ane akasiyana emuviri uye emakemikari zvimiro, izvo zvinokonzeresa kusiyanisa mhedzisiro pane weld seam.
1. Nitrogen (N2)
N2 ine ine mwero ionization simba, yakakwirira kupfuura Ar uye yakaderera kupfuura Iye. Pasi pechiito chelaser, inoisa ionize kune mwero dhigirii, zvinobudirira kuderedza kuumbwa kweplasma makore uye kuwedzera kushandiswa kwelaser. Nekudaro, nitrogen inogona kuita kemikari ine aruminiyamu alloys uye kabhoni simbi pane imwe tembiricha, ichigadzira nitrides. Izvi zvinogona kuwedzera brittleness uye kuderedza kuoma kwe weld seam, zvichikanganisa maitiro ayo emagetsi. Nokudaro, kushandiswa kwenitrogen segasi rinodzivirira realuminium alloys uye carbon steel welds hazvikurudzirwi. Kune rimwe divi, nitrogen inogona kuita nesimbi isina tsvina, ichigadzira nitrides inosimudzira kusimba kwejoint yeweld. Naizvozvo, nitrogen inogona kushandiswa segasi rinodzivirira rekushongedza simbi isina tsvina.
2. Argon Gasi (Ar)
Argon gasi ine yakaderera ionization simba, zvichikonzera yakakwira dhigirii yeionization pasi pelaser action. Izvi hazvina kunaka pakudzora kuumbwa kwemakore eplasma uye zvinogona kuve nemhedzisiro pakushandiswa kunoshanda kwema lasers. Nekudaro, argon ine yakaderera reactivity uye haigone kuita kemikari maitiro nemasimbi akajairika. Uyezve, argon inodhura-inoshanda. Uyezve, nekuda kwekuwanda kwayo, argon inonyura pamusoro pedziva re weld, ichipa dziviriro iri nani kune dziva re weld. Naizvozvo, inogona kushandiswa seyakajairwa kudzivirira gasi.
3. Helium Gasi (Iye)
Helium gasi ine yakanyanya ionization simba, inotungamira kune yakaderera dhigirii yeionization pasi pelaser chiito. Iyo inobvumira kudzora zviri nani kweplasma makore ekuumbwa, uye lasers anogona kunyatsopindirana nesimbi. Uyezve, helium ine yakaderera reactivity uye haingoite makemikari kuita nesimbi, zvichiita kuti ive gasi rakanakisa rekudzivirira weld. Nekudaro, mutengo wehelium wakakwira, saka kazhinji haushandiswe mukugadzirwa kwakawanda kwezvigadzirwa. Inonyanya kushandiswa mukutsvagisa kwesainzi kana kune-yakakwirira-yakawedzerwa zvigadzirwa.
Nzira mbiri dzeKushandisa Dziviriro Gasi
Parizvino, pane nzira mbiri huru dzekuunza gasi rekudzivirira: off-axis side blowing uye coaxial shielding gasi, sezvakaratidzwa muFigure 1 uye Mufananidzo 2, zvichiteerana.
Mufananidzo 1: Off-axis Side Inofuridza Shielding Gasi
Mufananidzo 2: Coaxial Shielding Gasi
Sarudzo pakati penzira mbiri dzekuridza zvinoenderana nemafungiro akasiyana.
Kazhinji, zvinokurudzirwa kushandisa off-axis side yekufuridza nzira yekudzivirira gasi.
Nzira Yekusarudza Gasi Rakanaka Rinodzivirira?
Chekutanga, zvakakosha kujekesa kuti izwi rekuti "oxidation" yewelds ishoko rekutaura. Muchiono, zvinoreva kudzikira kwemhando yeweld nekuda kwekuchinja kwemakemikari pakati pesimbi yeweld uye zvinhu zvinokuvadza zviri mumhepo, zvakaita seokisijeni, nitrogen, uye hydrogen.
Kudzivirira weld oxidation kunosanganisira kudzikisira kana kudzivirira kusangana pakati pezvinhu izvi zvinokuvadza uye nepamusoro-tembiricha weld simbi. Iyi yepamusoro-tembiricha mamiriro anosanganisira kwete chete yakanyungudutswa weld dziva simbi asiwo nguva yose kubva apo weld simbi inonyungudutswa kusvikira dziva raoma uye tembiricha yaro inoderera pazasi imwe chikumbaridzo.
Welding Process
Semuenzaniso, mukuputirwa kwetitanium alloys, kana tembiricha iri pamusoro pe300 ° C, kukurumidza kutorwa kwehydrogen kunoitika; pamusoro pe450 ° C, kukurumidza kutorwa kweokisijeni kunoitika; uye pamusoro pe600 ° C, kukurumidza kutora nitrogen kunoitika.
Naizvozvo, kudzivirira kunoshanda kunodiwa kune titanium alloy weld panguva yechikamu kana ichiomesa uye tembiricha yayo inoderera pasi pe300 ° C kudzivirira oxidation. Kubva pane tsananguro iri pamusoro apa, zviri pachena kuti gasi rekudzivirira rinoputika rinoda kupa dziviriro kwete chete kune weld pool panguva yakakodzera asiwo kune yakangosimbiswa-yakasimba nharaunda ye weld. Nekudaro, iyo off-axis side yekuvhuvhuta nzira inoratidzwa muFigure 1 inowanzofarirwa nekuti inopa hupamhi hwedziviriro kana ichienzaniswa neiyo coaxial shielding nzira inoratidzwa muFigure 2, kunyanya kune ingori-yakasimba nharaunda yeweld.
Nekudaro, kune zvimwe zvigadzirwa, kusarudzwa kweiyo nzira kunoda kuitwa zvichibva pane chigadzirwa chimiro uye majoini kumisikidzwa.
Kunyatsosarudzwa kweNzira Yekuunza Dziviriro Gasi
1. Straight-line Weld
Kana chigadzirwa cheweld chimiro chakatwasuka, sezviri kuratidzwa paMufananidzo 3, uye majoini ekumisikidza anosanganisira majoini emabutt, lap joints, fillet welds, kana stack welds, nzira inosarudzirwa yerudzi urwu rwechigadzirwa inzira yekufuridza padivi pe-axis inoratidzwa muFigure 1.
Mufananidzo 3: Straight-line Weld
2. Planar Yakavharwa Geometry Weld
Sezvinoratidzwa mumufananidzo 4, iyo weld mumhando iyi yechigadzirwa ine yakavharwa planar chimiro, senge denderedzwa, polygonal, kana akawanda-segment mutsara chimiro. Majoini magadzirirwo anogona kusanganisira butt joints, lap joints, kana stack welds. Kune rudzi urwu rwechigadzirwa, nzira inosarudzwa ndeye kushandisa iyo coaxial shielding gasi inoratidzwa muFigure 2.
Mufananidzo 4: Planar Yakavharwa Geometry Weld
Kusarudzwa kwekudzivirira gasi kune planar yakavharirwa geometry welds inobata zvakananga kunaka, kushanda zvakanaka, uye mutengo wekugadzira welding. Nekudaro, nekuda kwekusiyana kwezvinhu zvewelding, kusarudzwa kwegasi rekushongedza kwakaoma mune chaiyo welding maitiro. Zvinoda kutariswa kwakadzama kwezvinhu zvewelding, nzira dzewelding, zvinzvimbo zvewelding, uye inodiwa welding mhedzisiro. Kusarudzwa kweyakanyanya kufanira welding gasi inogona kutariswa kuburikidza newelding bvunzo kuti uwane yakakwana welding mhinduro.
