Zowonongeka Wamba mu Kuwotcherera kwa Laser ndi Momwe Mungathetsere

Kuwotcherera kwa laser ndi njira yabwino kwambiri komanso yolondola yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Komabe, zolakwika zina monga ming'alu, porosity, spatter, burn-through, ndi undercutting zitha kuchitika panthawiyi. Kumvetsetsa zomwe zimayambitsa zolakwikazi ndi njira zothetsera vutoli ndizofunikira kwambiri pakuwongolera khalidwe la kuwotcherera ndikuwonetsetsa zotsatira zokhalitsa. Pansipa pali zolakwika zazikulu zomwe zimapezeka pakuwotcherera kwa laser komanso momwe mungathanirane nazo:

1. Ming'alu

Chifukwa: Ming'alu imachitika chifukwa cha mphamvu yakuchulukirachulukira dziwe la weld lisanalimba. Nthawi zambiri zimagwirizanitsidwa ndi ming'alu yotentha, monga kulimbitsa kapena ming'alu ya liquation.

Yankho: Kuchepetsa kapena kuthetsa ming'alu, kutenthetsera ntchito yopangira ntchito ndikuwonjezera zinthu zodzaza kungathandize kugawa kutentha kwambiri, motero kuchepetsa kupsinjika ndikupewa ming'alu.

2. Porosity

Chifukwa: Kuwotcherera kwa laser kumapanga dziwe lakuya, lopapatiza la weld lozizira kwambiri. Mipweya yopangidwa mu dziwe losungunuka ilibe nthawi yokwanira yothawa, zomwe zimatsogolera kupanga matumba a mpweya (pores) mu weld.

Yankho: Kuti muchepetse porosity, yeretsani malo ogwirira ntchito musanawotcherera. Kuphatikiza apo, kusintha komwe kumayendera mpweya wotchingira kungathandize kuwongolera kutuluka kwa gasi ndikuchepetsa mwayi wopanga pore.

3. Spatter

Chifukwa: Spatter imagwirizana mwachindunji ndi kuchuluka kwa mphamvu. Kachulukidwe ka mphamvu kakachuluka kwambiri, zinthuzo zimasungunuka kwambiri, zomwe zimapangitsa kuti zinthu zosungunula ziwuluke kuchokera mu dziwe la weld.

Yankho: Kuchepetsa mphamvu kuwotcherera ndi kusintha liwiro kuwotcherera kuti mulingo woyenera kwambiri. Izi zithandiza kupewa vaporization ya zinthu zambiri komanso kuchepetsa kukwapula.

4. Kuwotcha

Chifukwa: Chilemachi chimachitika pamene liwiro la kuwotcherera limakhala lothamanga kwambiri, zomwe zimapangitsa kuti chitsulo chamadzimadzi chilephere kugawanso bwino. Zitha kuchitikanso pamene kusiyana kwa mgwirizano kuli kwakukulu kwambiri, kuchepetsa kuchuluka kwa zitsulo zosungunuka zomwe zilipo kuti zigwirizane.

Yankho: Polamulira mphamvu ndi liwiro la kuwotcherera mogwirizana, kuwotcha-kupyola kungalephereke, kuonetsetsa kuti dziwe la weld likuyendetsedwa mokwanira kuti likhale logwirizana.

5. Kudula

Chifukwa: Kuwotchera kumachitika pamene liwiro la kuwotcherera likucheperachepera, zomwe zimapangitsa kuti pakhale dziwe lalikulu, lalikulu. Kuchuluka kwachitsulo chosungunuka kumapangitsa kuti zikhale zovuta kuti zitsulo zamadzimadzi zikhale zovuta kuti zitsulo zamadzimadzi zikhalepo, zomwe zimapangitsa kuti ziwonongeke.

Yankho: Kuchepetsa kachulukidwe ka mphamvu kungathandize kupewa kuchepa, kuonetsetsa kuti dziwe losungunuka likusunga mawonekedwe ake ndi mphamvu panthawi yonseyi.

Udindo wa Madzi ozizira mu Laser Welding

Kuphatikiza pa mayankho omwe ali pamwambawa, kusunga kutentha kwabwino kwa laser welder ndikofunikira kuti mupewe zolakwika izi. Apa ndi pamene zoziziritsa madzi zimayamba kugwira ntchito. Kugwiritsa ntchito chiller madzi pa ndondomeko kuwotcherera laser n'kofunika chifukwa zimathandiza kusunga kutentha mogwirizana mu laser ndi workpieces. Mwa kuwongolera bwino kutentha m'dera lakuwotcherera, zoziziritsa kumadzi zimachepetsa malo omwe amakhudzidwa ndi kutentha ndikuteteza zida zowoneka bwino kuti zisawonongeke. Izi zimatsimikizira kukhazikika ndi khalidwe la mtengo wa laser, potsirizira pake kuwongolera khalidwe la kuwotcherera ndi kuchepetsa mwayi wa zolakwika monga ming'alu ndi porosity. Kuphatikiza apo, zoziziritsira madzi zimakulitsa moyo wa zida zanu popewa kutenthedwa ndikupereka ntchito yodalirika, yokhazikika.

Mapeto: Pomvetsa zomwe zimayambitsa vuto wamba laser kuwotcherera ndi kukhazikitsa njira zothandiza, monga preheating, kusintha zoikamo mphamvu ndi liwiro, ndi ntchito chillers, mukhoza kwambiri kusintha kuwotcherera khalidwe. Njirazi zimatsimikizira zinthu zapamwamba, zowoneka bwino komanso zolimba, komanso zimathandizira magwiridwe antchito komanso moyo wa zida zanu zowotcherera laser.

Kuti mumve zambiri zamomwe mungakwaniritsire njira yanu yowotcherera laser ndi njira zoziziritsira zapamwamba, omasuka kutilankhula nafe.
