Kuwotcherera kwa laserndi chimodzi mwa zinthu zofunika kwambiri pa ntchito laser processing chuma processing luso. Amagwiritsidwa ntchito kwambiri pakuwotcherera zinthu zoonda zokhala ndi mipanda komanso kuwotcherera kothamanga kwambiri. Njira yowotcherera ndi ya mtundu wa conduction wa kutentha, ndiye kuti, kuwala kwa laser kumatenthetsa pamwamba pa workpiece, ndipo kutentha kwapansi kumafalikira mkati mwa kutentha kwapakati. Poyang'anira magawo monga m'lifupi, mphamvu, mphamvu yapamwamba komanso kubwerezabwereza kwa laser pulse, The workpiece imasungunuka kupanga dziwe losungunuka. Amagwiritsidwa ntchito kwambiri popanga makina, zakuthambo, mafakitale amagalimoto, zitsulo zamafuta, mafakitale a biomedical microelectronics ndi magawo ena.
Ndi kukula kwamphamvu kwa magalimoto atsopano amphamvu, kukulitsa kwa batire yamagetsi kwachititsa kukula kwa kuwotcherera kwa laser. Kuyambira theka lachiwiri la 2018, kuwotcherera kwa laser m'manja kwayamba kutchuka pang'onopang'ono, ndipo kwakhala malo owala pamsika wa laser kuwotcherera mu theka loyamba la chaka chino. Ndi zamakono mlingo luso ndi ntchito zochitika zakuwotcherera m'manja laser, ndizotheka kusintha makina owotcherera a TIG (argon arc welding) msika.
Mzaka zaposachedwa,fiber laserszapita patsogolo kwambiri, ndipo ubwino wawo makamaka monga: mkulu photoelectric kutembenuka mlingo, mofulumira kutentha kutentha, kusinthasintha bwino, amphamvu odana ndi kusokoneza mphamvu, mtengo wotsika, moyo wautali, zosintha, wopanda kukonza, kukhazikika kwapamwamba, kukula pang'ono, Pamanja zida kuwotcherera laser pogwiritsa ntchito CHIKWANGWANI lasers nawonso pang'onopang'ono anayamba.
Kuwotcherera kwa laserkumafuna kulondola kwakukulu kwa chogwiritsira ntchito, ndipo msoko wowotcherera umakhala wovuta. Kuti athetse vutoli, mlengi amatanthauza zida kuwotcherera laser ndege yapadera kupanga m'manja laser kuwotcherera zida ndi malo akugwedezeka. Laser ali mu mawonekedwe a "8" kapena "0" mtundu kusambira akhoza kuchepetsa kulondola msonkhano wa workpiece ndi kuonjezera kuwotcherera malowedwe. Pambuyo kukhathamiritsa ndi kuwongolera kambiri, zida zamakono zowotcherera zam'manja za laser zili ndi mphamvu ya 0.5-1.5KW, ndipo kukula ndi kulemera kwa zidazo ndizofanana ndi makina owotcherera a argon, omwe amatha kuwotcherera mbale zachitsulo za 3mm kapena kuchepera. Pofuna kuthetsa zolakwa za osakwanira kuwotcherera mphamvu ya nyumba laser kuwotcherera, m'zaka zaposachedwapa, opanga zida Integrated basi waya kudyetsa zipangizo pamaziko a laser kuwotcherera, ndipo anayamba m'manja laser waya-kudzaza zida kuwotcherera kuti akhoza basi kudyetsa mawaya, amene kwenikweni amakwaniritsa zosowa za mbale woonda zitsulo pansi pa 4m. Kuwotcherera kungathe m'malo mwake ndikuposa kuwotcherera kwa argon arc, kuzindikira kuthamanga kwambiri, kuyika kwa kutentha pang'ono, kupindika pang'ono, kuwotcherera kotsika mtengo kwachitetezo cha chilengedwe, ndipo mtengo wopangira ndi wotsika kuposa wowotcherera argon arc pansi pamikhalidwe yomweyi.
Pogwira ntchito, mutu wogwirizira m'manja wa makina owotcherera umakhala ndi m'lifupi mwake, ndipo m'mimba mwake m'mimba mwake ndi waung'ono, kotero powotcherera, amasanthula kuchokera kumalo ena kupita kumalo ena mzere ndi mzere, motero amapanga mkanda wowotcherera. Poyerekeza ndi chikhalidwe ozizira kuwotcherera makina, kuwotcherera liwiro la dzanja unagwira laser kuwotcherera adzakhala mofulumira, ndi kuwombera njira kuwotcherera mmodzi amaona kuti ndi oyenera kuwotcherera misa wa seams yaitali molunjika.
Ndipo makina owotcherera a laser opangidwa ndi manja amatenga malo ochepa, ndipo nthawi zambiri amakhala ndi mitu yosiyanasiyana yogwira manja. Malinga ndi zosowa zosiyanasiyana za zitsulo monga kuwotcherera kunja, kuwotcherera mkati, kuwotcherera kumanja, kuwotcherera m'mphepete, ndi kuwotcherera kwa malo akuluakulu, mitu yowotcherera yamanja imatha kusankhidwa. Zogulitsa zomwe zimatha kuwotcherera zimakhala zosiyanasiyana, ndipo mawonekedwe ake amakhala osinthika. Kwa zokambirana zopanga zomwe zimagwira ntchito zazing'onoting'ono komanso kuwotcherera osati zazikulu, makina owotcherera am'manja a laser ndiye chisankho chabwino kwambiri.
Zida zosiyanasiyana zachitsulo zimakhala ndi malo osungunuka osiyanasiyana: kuyika kwa magawo owotcherera kwa mitundu yosiyanasiyana ya zida zowotcherera kumakhala kovuta, ndipo mawonekedwe a thermophysical azinthu zowotcherera adzawonetsa kusiyana kosiyana ndi kusintha kwa kutentha; kuchuluka kwa mayamwidwe amitundu yosiyanasiyana ya zida za laser kumasiyananso ndi Kusintha kwa kutentha kumawonetsa kusiyana kosiyana; kusungunuka kwa mgwirizano wa solder ndi kusintha kwapangidwe kwa malo omwe amakhudzidwa ndi kutentha panthawi ya kulimba kwa zitsulo; olowa zofooka za dzanja unachitikira laser kuwotcherera makina, kuwotcherera nawo nkhawa ndi mapindikidwe matenthedwe matenthedwe, etc. Koma chofunika kwambiri ndi chikoka cha kusiyana katundu wa kuwotcherera zipangizo pa zazikulu ndi zazing'ono katundu wa weld.
Zida zomwe zingathekemakina owotcherera pamanja a laserweld?
1. Chitsulo chosapanga dzimbiri
Chitsulo chosapanga dzimbiri chimakhala ndi mphamvu yayikulu yowonjezera kutentha, ndipo chimakonda kutentha kwambiri panthawi yowotcherera. Malo omwe amakhudzidwa ndi kutentha ndiakulu pang'ono, zingayambitse mavuto aakulu. Komabe, kutentha kopangidwa ndi makina owotcherera m'manja a laser panthawi yonse yowotcherera ndikotsika. Kuphatikizidwa ndi kutsika kwamafuta otsika, kutsika kwamphamvu kwamphamvu komanso kusungunuka kwachitsulo chosapanga dzimbiri, ma welds opangidwa bwino, osalala komanso okongola amatha kupezeka pambuyo kuwotcherera.
2. Chitsulo cha carbon
Wamba mpweya zitsulo akhoza welded mwachindunji ndi dzanja anagwira laser kuwotcherera, zotsatira zake n'zofanana ndi kuwotcherera zitsulo zosapanga dzimbiri, ndi zone kutentha okhudzidwa ndi ang'onoang'ono, koma pamene kuwotcherera sing'anga ndi mkulu mpweya zitsulo, kutentha yotsalira ndi mkulu, choncho akadali kofunika kuwotcherera pamaso kuwotcherera. Preheating ndi kuteteza kutentha pambuyo kuwotcherera kuthetsa nkhawa ndi kupewa ming'alu. Apa tikhoza kulankhula za makina ozizira kuwotcherera. Sing'anga ndi mkulu mpweya zitsulo akhoza welded kapena kukonzedwa pa liwiro pang'onopang'ono ndi kuwotcherera ozizira ndi kuponyedwa chitsulo kuwotcherera waya. Pankhani ya kuwongolera kutentha, kuwongolera kutentha, ndi kuwongolera kutentha, makina owotcherera ozizira amatha kuphunzitsa kuwotcherera kwa laser yogwirizira pamanja bwino pa zotsalira za kutentha pambuyo pakuwotcherera.
3. Chitsulo chakufa
Ndi oyenera kuwotcherera mitundu yosiyanasiyana ya kufa zitsulo, ndi kuwotcherera zotsatira zabwino kwambiri.
4. Aluminiyamu ndi zitsulo zotayidwa
Aluminiyamu ndi zitsulo zotayidwa ndi zonyezimira kwambiri, ndipo porosity imatha kuwoneka mu dziwe losungunuka kapena pamizu panthawi yowotcherera. Poyerekeza ndi zitsulo zam'mbuyo zam'mbuyo, zitsulo zotayidwa ndi aluminiyamu zimakhala ndi zofunikira zapamwamba pazigawo, koma malinga ngati zosankhidwa zowotcherera zili zoyenera , msoko wowotcherera womwe uli ndi makina ofanana ndi zitsulo zoyambira zimatha kupezeka.
5. Copper ndi copper alloy
The matenthedwe madutsidwe mkuwa ndi wamphamvu kwambiri, ndipo n'zosavuta chifukwa chosakwanira malowedwe ndi tsankho maphatikizidwe pa kuwotcherera. Nthawi zambiri, zinthu zamkuwa zimatenthedwa panthawi yowotcherera kuti zithandizire kuwotcherera. Apa tikukamba za zipangizo zamkuwa zopyapyala. M'manja laser kuwotcherera akhoza mwachindunji kuwotcherera, chifukwa cha anaikira mphamvu ndi kusala kuwotcherera liwiro, ndi zochepa anakhudzidwa ndi mkulu matenthedwe madutsidwe mkuwa.
6. Kuwotcherera pakati pa zipangizo zosiyana
Makina ogwiritsira ntchito laser kuwotcherera pamanja amatha kuchitidwa pakati pa zitsulo zosiyanasiyana zosiyana, monga mkuwa-nickel, nickel-titaniyamu, mkuwa-titaniyamu, titaniyamu-molybdenum, mkuwa-mkuwa, chitsulo chochepa cha carbon-mkuwa ndi zitsulo zina zosiyana. Kuwotcherera kwa laser kutha kuchitika pansi pazifukwa zilizonse (gasi kapena kutentha).
M'manja laser kuwotcherera makina panopa ndi chimagwiritsidwa ntchito makampani kuwotcherera, makamaka chifukwa ngakhale chipangizo ichi akuwoneka okwera mtengo, akhoza kupulumutsa ndalama ntchito bwino kwambiri. Mtengo wa ntchito zowotcherera ndi wokwera mtengo. Kugwiritsa ntchito izi Mankhwalawa amathetsa vuto la ndalama zokwera mtengo komanso zovuta kulemba ma welder. Komanso, makina owotcherera m'manja a laser apambana matamando ochokera kwamakasitomala ambiri chifukwa cha moyo wake wautali komanso kugwiritsa ntchito mphamvu zochepa.
Ngati mukufuna kudziwa zambiri za kuyeretsa laser, kapena mukufuna kukugulirani makina abwino kwambiri oyeretsera laser, chonde siyani uthenga patsamba lathu ndikutumiza imelo mwachindunji!
