Nkhani - Ndi mitundu ingati ya kuwotcherera kwa laser yomwe mukudziwa?

1 Kuwotcha kwa laser

(1) Mfundo

Laser brazing ndi njira yowotcherera yomwe imagwiritsa ntchito laser ngati gwero la kutentha, imagwiritsa ntchito zinthu zomwe zimakhala ndi malo otsika osungunuka kuposa zitsulo zoyambira monga zitsulo zodzaza (zotchedwa solder), zikatenthetsa ndi kusungunuka, zimagwiritsa ntchito solder zamadzimadzi kunyowetsa zitsulo, kudzaza kusiyana ndi phatikizani ndi chitsulo choyambira kuti mukwaniritse kulumikizana, monga tawonera pachithunzichi.

(2) Mbali

Kuwotcherera kwa laser kumagwiritsidwa ntchito powotcherera, zomwe sizimangopangitsa kuti mankhwalawa azikhala okongola komanso amawongolera kusindikiza, komanso kumapangitsanso mphamvu ya malo otsekemera ndikuwongolera chitetezo cha galimoto.Njira yolumikizira zitsulo zoyambira ndi ya crimping butt joint, monga momwe zilili m'chithunzichi.

(3) Malo ogwiritsira ntchito

Laser brazing ndi njira yowotcherera yomwe imagwiritsidwa ntchito kwambiri pakuwotcherera thupi pamagalimoto pakadali pano.Ubwino wake waukulu ndikuti ukhoza kupanga pamwamba komanso kupewa kusungunuka kwa zinc.Amagwiritsidwa ntchito makamaka pa: cholumikizira pakati pa khoma lakunja lambali ndi chivundikiro chapamwamba chakunja (monga momwe tawonetsera pa Chithunzi 1 ndi Chithunzi 2, mzere wosindikiza mphira wa padenga umathetsedwa, womwe ndi wokongola komanso wopulumutsa ndalama);Gwirizanitsani zigawo zakumwamba ndi zapansi za gulu lakunja la chivundikiro cha thunthu (monga momwe tawonetsera pa Chithunzi 3)

2 Kuwotcherera kwa laser fusion

(1) Mfundo

Laser maphatikizidwe kuwotcherera ndi njira kuwotcherera ntchito laser monga gwero kutentha kusungunula mbali ya zitsulo m'munsi mwa mbale ziwiri pa ngodya olowa mbale ziwiri (panthawi yomweyo, kusungunula chapafupi kuwotcherera waya kudzaza ngodya olowa mbale ziwiri) kuti kupanga zitsulo zamadzimadzi, kenako pangani kulumikizana kodalirika pambuyo pozizira.Ndondomeko yake ya ndondomeko ikuwonetsedwa mu Chithunzi 3.

(2) Mbali

Kuwotcherera kwa laser fusion kumatha kugawidwa kukhala kuwotcherera kwa laser kulowa, kuwotcherera kwa laser fusion (popanda kudzaza waya) ndi kuwotcherera kwa waya wa laser fusion.Amagwiritsidwa ntchito kwambiri powotcherera kutsogolo kwa galimoto, chivundikiro chapamwamba ndi pansi, khomo lamkati lamkati, ndi zina zotero. Chitsulo choyambira chimagwirizanitsidwa ndi kupukuta, monga momwe tawonetsera pa Chithunzi 4.

(3) Malo ogwiritsira ntchito

Kuwotcherera kwa laser kumagwiritsidwa ntchito kwambiri padenga ndi chitseko.Chithunzi 5 chikuwonetsa kugwiritsa ntchito kuwotcherera kwa laser fusion pakhomo lakumbuyo lagalimoto.
