Ndi mitundu ingati ya kuwotcherera laser yomwe mukudziwa?

Ubwino ndi Kuipa kwa Laser Welding wa Aluminiyamu Aloyi

Pamene laser kuwotcherera zotayidwa aloyi, monga kuwotcherera mbale kanasonkhezereka zitsulo, pores ambiri ndi ming'alu adzapangidwa pa ndondomeko kuwotcherera, zomwe zidzakhudza kuwotcherera khalidwe.Chigawo cha aluminiyamu chimakhala ndi mphamvu zochepa za ionization, kusasunthika kosasunthika, komanso kumayambitsa kuwotcherera.Kuphatikiza pa njira yowotcherera yotentha kwambiri, aluminium oxide ndi aluminium nitride zidzapangidwa panthawi yonseyi, zomwe zimayambitsa kuipitsa chilengedwe.

Komabe, zotayidwa aloyi mbale pamwamba akhoza opukutidwa pamaso kuwotcherera kuonjezera mayamwidwe ake laser mphamvu;Gasi wa inert azigwiritsidwa ntchito powotcherera kuti apewe mabowo a mpweya.

Kuwotcherera kwa laser arc hybrid aloyi ya aluminiyamu kwathetsa mavuto a mphamvu yowotcherera ya laser, kuyamwa kwa mtengo wa laser pamwamba pa aluminiyumu aloyi ndi mtengo wapakatikati pakuwotcherera kwakuya.Ndi imodzi mwa njira zowotcherera za aluminium alloy.Pakalipano, ndondomekoyi siinakhwima ndipo ili mu kafukufuku ndi kufufuza.

Kuvuta kwa kuwotcherera kwa laser ndikosiyana kwamitundu yosiyanasiyana ya aluminiyamu.The sanali kutentha mankhwala analimbitsa zotayidwa ndi zotayidwa aloyi 1000 mndandanda, 3000 mndandanda ndi 5000 mndandanda ndi weldability wabwino;4000 mndandanda aloyi ali otsika kwambiri mng'alu tilinazo;Kwa 5000 mndandanda wa aloyi, pamene ω Pamene (Mg) = 2%, alloy imapanga ming'alu.Ndi kuchuluka kwa magnesium, ntchito yowotcherera imayenda bwino, koma ductility ndi kukana dzimbiri kumakhala koyipa;2000 mndandanda, 6000 mndandanda ndi 7000 mndandanda wa ma aloyi ali ndi chizolowezi chachikulu chosweka, kupangika kowotcherera kosawoneka bwino, komanso kuchepa kwakukulu kwa kuuma kokalamba pambuyo pa kuwotcherera.

Choncho, kwa laser kuwotcherera aloyi zotayidwa, m`pofunika kutengera njira zoyenera ndondomeko ndi kusankha molondola njira kuwotcherera ndi njira kupeza zotsatira zabwino kuwotcherera.Pamaso kuwotcherera, pamwamba mankhwala a zipangizo, ulamuliro wa kuwotcherera magawo ndondomeko ndi kusintha kamangidwe kuwotcherera onse njira zothandiza.

Kusankha magawo owotcherera

* Mphamvu ya laser 3KW.

Kuthamanga kwa laser kuwotcherera: 4m / min.Liwiro kuwotcherera zimadalira mphamvu kachulukidwe.Kuchuluka kwa mphamvu zowotcherera kumapangitsanso kuthamanga kwambiri.

· Pamene mbale ndi kanasonkhezereka (monga 0.8mm kwa mbali khoma mbale akunja ndi 0.75mm kwa pamwamba chivundikiro mbale akunja), chilolezo msonkhano umalamulidwa ndi pakati, zambiri 0.05 ~ 0.20mm.Pamene weld ali osachepera 0,15 mm, nthunzi ya zinc sungachotsedwe pambali, koma imachotsedwa pamtunda, zomwe zimakhala zosavuta kutulutsa zolakwika za porosity;Pamene kuwotcherera m'lifupi ndi wamkulu kuposa 0,15 mm, chitsulo chosungunuka sichingathe kudzaza kusiyana, zomwe zimapangitsa kuti pakhale mphamvu zosakwanira.Pamene makulidwe a weld ndi ofanana ndi a mbale, makina amakina ndi abwino kwambiri, ndipo m'lifupi mwake kumadalira kukula kwake;Kuzama kwa weld kumadalira kuchuluka kwa mphamvu, kuthamanga kwa kuwotcherera komanso kuyika kwake.

· Gasi wotetezera ndi argon, kutuluka kwake ndi 25L / min, ndipo kuthamanga kwa ntchito ndi 0.15 ~ 0.20MPa.

· Kuyikira m'mimba mwake 0.6 mm.

· Kuyikirapo: pamene makulidwe a mbale ndi 1mm, kuyang'ana kumangoyang'ana pamwamba, ndipo malo owonetsetsa amadalira mawonekedwe a cone.
