Laser weldingchimwe chezvinhu zvakakosha zvekushandiswa kwelaser processing material processing technology. Inonyanya kushandiswa kugadzira zvinhu zvakatetepa-madziro uye yakaderera-kumhanya welding. Iyo welding process ndeyemhando yekupisa conduction, kureva, laser radiation inopisa pamusoro peiyo workpiece, uye kupisa kwepamusoro kunopararira mukati kuburikidza nekupisa conduction. Nekudzora ma paramita akadai sehupamhi, simba, simba repamusoro uye kudzokorora frequency ye laser pulse, Iyo workpiece inonyunguduka kuumba chaiyo yakanyungudutswa dziva. Yakanyanya kushandiswa mukugadzira michina, aerospace, indasitiri yemotokari, poda metallurgy, biomedical microelectronics indasitiri uye mamwe minda.
Nekukura kwekuputika kwemotokari nyowani dzesimba, kuwedzera kwesimba rekugadzira bhatiri kwakafambisa kukura kwelaser welding. Kubva muhafu yechipiri ye2018, handheld laser welding yakawedzera mukurumbira, uye yave nzvimbo inopenya mumusika welaser welding muhafu yekutanga yegore rino. Neyezvino tekinoroji level uye mashandisirwo emamiriro ehandheld laser welding, zvinokwanisika kutsiva yechinyakare TIG welding muchina (argon arc welding) musika.
Mumakore achangopfuura,fiber lasersvakaita kufambira mberi kukuru, uye zvakanakira zvavo zvinonyanya zvinosanganisira: yakakwira photoelectric kutendeuka chiyero, kukurumidza kupisa kupisa, kuchinjika kwakanaka, kwakasimba kurwisa-kupindira kugona, mutengo wakaderera, hupenyu hurefu, gadziriso-isina, gadziriso-isina, kugadzikana kwepamusoro, diki saizi, Hand-yakabatwa laser welding midziyo uchishandisa fiber lasers yakagadziridzwawo zvishoma nezvishoma.
Laser weldinginoda kurongeka kwakakwirira kweiyo workpiece, uye weld seam inowanzoitika kune hurema. Kugadzirisa dambudziko iri, mugadziri anoreva laser welding midziyo yeyakakosha ndege kugadzira ruoko rwakabata laser welding midziyo ine nzvimbo inotenderera. Iyo laser iri muchimiro che "8" kana "0" mhando yekuzunguza inogona kuderedza kurongeka kwegungano kweiyo workpiece uye kuwedzera welding kupinda. Mushure mekutevedzana kwekugadzirisa uye kugadzirisa, yazvino yakajairwa handheld laser welding midziyo ine simba re 0.5-1.5KW, uye saizi uye huremu hwemidziyo yakaenzana neargon arc welding michina, inogona kupinza marata esimbi e3mm kana pasi. Kuti ugadzirise zvikanganiso zvekusakwana kwesimba rekuisa weld yelaser welding zvimiro, mumakore achangopfuura, vagadziri vezvishandiso vakabatanidza otomatiki waya yekudyisa michina pahwaro hwelaser welding, uye vakagadzira-yakabatwa nemaoko laser waya-yekuzadza welding michina inogona kudyisa wotomatiki waya, izvo zvinonyatso kusangana nezvinodiwa zvemarata matete esimbi ari pasi pe4m. Iyo welding inogona kutsiva nekupfuura argon arc welding, kuona kumhanya kwakadzika, kupisa kwakaderera kupinza, diki deformation, yakaderera-inodhura yekudzivirira nharaunda welding, uye mutengo wekugadzira wakaderera pane uya weargon arc welding pasi pemamiriro akafanana.
Paunenge uchishanda, musoro unobatwa nemaoko wemuchina welding une hupamhi hwekuvheneka, uye dhayamita yaro idiki, saka kana welding, inoongorora kubva pane imwe nzvimbo kuenda kune imwe pfungwa mutsara nemutsara, nokudaro ichigadzira weld bead. Kuenzaniswa neyechinyakare inotonhora welding muchina, iyo welding yekumhanyisa yeruoko-yakabatwa laser welding ichave nekukurumidza, uye imwe-pfuti yewelding process inoona kuti yakanyanya kufanirwa kune yakawanda welding yeakareba akatwasuka seams.
Uye iyo inobatwa nemaoko laser welding muchina inotora nzvimbo shoma, uye inowanzo shongedzerwa nemisoro yakasiyana-siyana inobatwa nemaoko. Zvinoenderana nezvinodiwa zvakasiyana zvezvikamu zvesimbi senge welding yekunze, welding yemukati, yekurudyi-angle welding, yakamanikana edge welding, uye yakakura nzvimbo welding, akasiyana-anobata misoro welding anogona kusarudzwa. Zvigadzirwa zvinogona kugadzirwa zvakasiyana-siyana, uye chimiro chechigadzirwa chinowedzera kushanduka. Kune mashopu ekugadzira anoitwa mudiki-zviyero kugadzirisa uye isiri-hombe-chikero welding, handheld laser welding michina zvirokwazvo ndiyo yakanakisa sarudzo.
Zvinhu zvakasiyana-siyana zvesimbi zvine zvakasiyana-siyana zvekunyunguduka: kugadzika kwekugadzirisa maparameter emhando dzakasiyana-siyana dzezvinhu zvekugadzira zvinenge zvakaoma, uye thermophysical properties ye welding zvinhu zvicharatidza kusiyana kwakasiyana nekushanduka kwekushisa; chiyero chekunyura chemhando dzakasiyana dzezvishandiso zvelaser zvichasiyanawo neThe tembiricha shanduko inoratidza misiyano yakasiyana; iyo solder yakanyunguduka yakanyunguduka uye kushanduka kwemaitiro enzvimbo inopisa-inopisa panguva yekusimbiswa kweiyo weldment; kukanganisa kwakabatana kwemaoko-akabata laser welding machine, welding participation stress and thermal deformation, etc. Asi chinonyanya kukosha ndechekuita mutsauko wezvinhu zvezvinhu zvewelding pane macro uye micro properties ye weld.
Ndezvipi zvinhu zvinogonaruoko-akabata laser welding muchinaweld?
1. Simbi isina tsvina
Simbi isina simbi ine yakakwira coefficient yekuwedzera kwekupisa, uye inogara ichipisa zvakanyanya panguva yewelding. Kana iyo inopisa-yakakanganiswa nzvimbo yakakura zvishoma, zvinokonzeresa zvakakomba deformation matambudziko. Nekudaro, kupisa kunogadzirwa neruoko rwelaser welding muchina panguva yese yewelding process yakadzikira. Yakabatana neyakadzikira yekupisa conductivity, yakakwira simba yekunyudza mwero uye kunyunguduka kwesimbi isina tsvina, yakanyatso kuumbwa, yakatsetseka uye yakanaka welds inogona kuwanikwa mushure mekugadzira.
2. Carbon steel
Yakajairwa kabhoni simbi inogona kukwenenzverwa yakananga neruoko-inobata laser welding, mhedzisiro yacho inofananidzwa nesimbi isina simbi, uye nzvimbo inobatwa nekupisa idiki, asi kana welding yepakati uye yakakwira kabhoni simbi, tembiricha yasara yakakwira, saka zvichiri kudiwa kuti weld isati yaiswa. Preheating nekuchengetedza kupisa mushure mekushongedza kuti ubvise kushushikana uye kudzivirira kutsemuka. Pano tinogona kutaura nezve inotonhora welding muchina. Simbi yepakati uye yakakwira kabhoni inogona kuvezwa kana kugadziriswa nekumhanya kunononoka neinotonhora welding uye yakakandwa iron welding waya. Panyaya yekudzora tembiricha, kudzora tembiricha, uye tembiricha yekudzora, inotonhora welding muchina unogona kudzidzisa ruoko-wakabatwa laser welding zvakanyanya kushanda pane yakasara yekupisa mushure mekutsvaira.
3. Die simbi
Yakakodzerwa nekubika mhando dzakasiyana dzesimbi inofa, uye iyo welding mhedzisiro yakanaka kwazvo.
4. Aluminium uye aluminium alloy
Aluminium nealuminium alloys zvinhu zvinoratidzira zvakanyanya, uye porosity inogona kuoneka mudziva rakanyungudutswa kana pamudzi panguva yewelding. Kuenzaniswa neyakapfuura simbi zvinhu, aruminiyamu uye aruminiyamu alloys ane yakakwirira zvinodiwa parameters, asi chero bedzi akasarudzwa welding parameters akakodzera , weld musono ane zvakafanana mechanical properties sezvo base simbi inogona kuwanikwa.
5. Copper nemhangura alloy
Thermal conductivity yemhangura yakasimba kwazvo, uye zviri nyore kukonzera kusakwana kupinza uye chidimbu fusion panguva welding. Kazhinji, zvinhu zvemhangura zvinopisa panguva yekugadzira welding kuti ibatsire welding. Pano tiri kutaura pamusoro pezvinhu zvitete zvemhangura. Hand-yakabatwa laser welding inogona zvakananga Welding, nekuda kweiyo yakadzika simba uye nekukurumidza welding yekumhanyisa, haina kukanganiswa neiyo yakakwira yekupisa conductivity yemhangura.
6. Welding pakati pezvinhu zvakasiyana
Muchina unobatwa nemaoko laser welding muchina unogona kuitwa pakati peakasiyana simbi dzakasiyana, senge mhangura-nickel, nickel-titanium, mhangura-titanium, titanium-molybdenum, ndarira-mhangura, yakaderera kabhoni simbi-mhangura uye mamwe masimbi akasiyana. Laser welding inogona kuitwa pasi pemamiriro ese (gasi kana tembiricha).
Handheld laser welding muchina parizvino chigadzirwa chinoshandiswa zvakanyanya muindasitiri yewelding, kunyanya nekuti kunyangwe mudziyo uyu unotaridzika uchidhura, unogona kuchengetedza mutengo wevashandi zvakanyanya. Mutengo webasa wevelder unodhura zvakanyanya. Kushandisa ichi Chigadzirwa chinogadzirisa dambudziko rekudhura uye kwakaoma kuunganidza welders. Zvakare, iyo handheld laser welding muchina wahwina kurumbidzwa kwakabvumirana kubva kuzviuru zvevatengi nekuda kwehupenyu hwayo hwesevhisi uye kushomeka kwesimba rekushandisa.
Kana iwe uchida kudzidza zvakawanda nezve laser yekuchenesa, kana uchida kukutengera yakanakisa laser yekuchenesa muchina, ndapota siya meseji pane yedu webhusaiti uye titumire email zvakananga!
