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, mphamvu zolimbana ndi kusokoneza, mtengo wotsika, moyo wautali, kusintha-free, kusakonza, kukhazikika kwapamwamba, kukula kochepa, Dzanja. -zida zowotcherera za laser zogwiritsa ntchito ma fiber lasers zayambanso pang'onopang'ono.

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 ili mu mawonekedwe a "8" kapena "0" kugwedezeka kwamtundu kumatha kuchepetsa kulondola kwa msonkhano ndikuwonjezera kulowera kowotcherera. Pambuyo pakukhathamiritsa ndi kuwongolera kambiri, zida zowotcherera zam'manja zapamanja za laser zili ndi mphamvu ya 0,5 -1.5KW, ndi kukula ndi kulemera kwa zida ndi ofanana ndi argon Arc kuwotcherera makina, amene angathe kuwotcherera mbale zitsulo 3mm kapena zochepa. opanga aphatikiza zida zopangira mawaya zodziwikiratu pamaziko a kuwotcherera kwa laser, ndikupanga zida zowotcherera zonyamula pamanja za laser zomwe zimatha kudyetsa mawaya, zomwe zimakwaniritsa zofunikira za mbale zoonda zachitsulo zosakwana 4m. kuwotcherera kwa argon arc, kuzindikira kuthamanga kwambiri, kulowetsa kutentha pang'ono, kusinthika pang'ono, kuwotcherera kwachitetezo cha chilengedwe chotsika mtengo, ndipo mtengo wopanga ndi wotsika kuposa wa argon arc welding u.pansi pa zikhalidwe zomwezo.

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 yowonjezera yowonjezera kutentha, ndipo chimakonda kutentha kwambiri panthawi yowotcherera.Malo omwe amakhudzidwa ndi kutentha akakula 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 okhudzidwa ndi kutentha ndi yaing'ono, koma pamene kuwotcherera sing'anga ndi mkulu mpweya zitsulo, kutentha yotsalira ndi mkulu, kotero izo. akadali ofunika 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 ozizira kuwotcherera 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!
