ʻenehana welding o PDC

undefined


E like me kā mākou ʻatikala hope e hōʻike nei, e like me ke ʻano o ka hoʻomehana ʻana, hiki ke hoʻokaʻawale ʻia ke ʻano o ka brazing i loko o ka lapalapa ahi, ka ʻūlū ʻana, ka hoʻopaʻa ʻana i ka vacuum diffusion, ka hoʻopili ʻana i ka induction kiʻekiʻe, ka welding laser beam, etc. Ma kēia ʻatikala e hoʻomau i kēia luna a hiki mai i ke kiʻekiʻe-frequency induction brazing, a me ka laser beam welding.


PDC kiʻekiʻe-frequency induction brazing


Ke hoʻohana nei ʻo High-frequency induction brazing i ka electromagnetic induction e hoʻohuli i ka ikehu electromagnetic i ka ikehu wela i loko o ka mea hoʻopihapiha hoʻopihapiha hoʻopihapiha a me ka mea hana, e hoʻomehana ana i ka metala hoʻopiha piha i kahi kūlana hoʻoheheʻe. ʻO ke kaʻina hana brazing induction kiʻekiʻe o PDC ka ʻenehana koʻikoʻi no ka pale ʻana i nā mea hana ʻoki PDC.


ʻO ka maikaʻi o ka PDC high-frequency induction brazing:


1.    wikiwiki ka wikiwiki o ka hoʻomehana ʻana, hiki ke hōʻemi i ka nalowale ʻana o ka PDC polycrystalline diamond layer a me ke degere oxidation o ka carbide cemented.

2.    hōʻoia i ka pololei o ke ana o nā ʻāpana

3.    ʻaneʻane ʻaʻohe haumia kaiapuni

4.    maʻalahi ka hoʻomaopopo ʻana i ka automation hana.


PDC kukuna kukuna kukuna


Hoʻohana ʻia ʻo Laser Beam Welding i kahi kukuna laser density kiʻekiʻe e like me ke kumu wela, ma ka hoʻomalu ʻana i ka laulā pulse laser, ka ikehu, ka mana kiʻekiʻe, ka hana pinepine ʻana, a me nā ʻāpana ʻē aʻe e hiki ai ka mea hana i kahi hohonu o ka wai hoʻoheheʻe, ʻoiai ua loaʻa ka ʻili. ʻaʻohe vaporization maopopo, no laila hiki ke hoʻokō ʻia ke kuʻi ʻana.


Hiki i ka mana o ka laser beam ke hiki i ka 10 9 W / cm 2. Ma muli o ke kiʻekiʻe o ka mana kiʻekiʻe, ua hoʻokumu ʻia nā lua liʻiliʻi i ka mea metala i ka wā o ke kaʻina hana kuʻi.


Hoʻouna ʻia ka ikehu laser i ka ʻāpana hohonu o ka mea hana ma o nā lua liʻiliʻi, e hōʻemi ana i ka diffusion lateral a me ka hohonu fusion o ka mea.


ʻO nā hiʻohiʻona o ka welding beam laser:


1.    ka hohonu fusion nui o ka mea, ka māmā wiliwili wikiwiki, a me ka wahi wili nui i kēlā me kēia manawa.

2.    wili weld hohonu a haiki, wahi liʻiliʻi i hoʻopili ʻia me ka wela, a me ka deformation wili.


Ke hoʻohana nei i ka laser e weld PDC, ʻo ka hui welded i loaʻa i ka ikaika kiʻekiʻe, a hiki i 1 800 MPa, a ʻaʻole e hōʻino i ka papa daimana. He ala kuʻihao PDC maikaʻi loa ia, ka mea i hoʻohana nui ʻia no ka wiliwili ʻana i nā lau o ka daimana.


ʻO ka noiʻi a me ka hoʻolaha ʻana o PDC ua hoʻomaikaʻi maikaʻi i ka hiki ke ʻoki i nā ʻāpana drill a me nā mea hana a hoʻohālikelike ʻia me ke daimana maoli, he maikaʻi ke kumu kūʻai. Ke noʻonoʻo nei i nā koi hana a me ke kumukūʻai o PDC, hiki ke koho ʻia kahi kaʻina hana kuʻi kūpono.

Inā makemake ʻoe i nā mea ʻoki PDC a makemake ʻoe i nā ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.

E HOOHUNA MAI I KA LEKA
E ʻoluʻolu e leka a e hoʻi mākou iā ʻoe!
