ʻEhia ʻano o ka welding laser āu i ʻike ai?

ʻO nā pono a me nā pōʻino o Laser Welding o Aluminum Alloy

I ka wā e hoʻoheheʻe ʻia ai ka alumini alumini, e like me ka hoʻopili ʻana o ka pā kila galvanized, nui nā pores a me nā māwae e hana ʻia i ka wā o ke kaʻina hana kuʻi, e hoʻopilikia i ka maikaʻi o ka welding.ʻO ka mea alumini he haʻahaʻa ionization ikehu, maikaʻi ʻole ka hoʻopaʻa ʻana i ke kuʻi ʻana, a ke kumu hoʻi i ka pau ʻole o ka wili.Ma kahi o ke kaʻina hana welding wela, e hana ʻia ka alumini oxide a me ka nitride aluminika i ke kaʻina holoʻokoʻa, e hoʻohaumia ai i ke kaiapuni.

Eia naʻe, hiki ke hoʻomaʻamaʻa ʻia ka ʻili o ka pā alumini alumini ma mua o ke kuʻi ʻana e hoʻonui i kona absorption o ka ikehu laser;E hoʻohana ʻia ke kinoea inert i ka wā wili e pale ai i nā lua ea.

Laser arc hybrid welding of aluminum alloy ua hoʻonā i nā pilikia o ka mana welding laser, absorption o ka laser beam ma luna o ka ʻili o ka alumini alumini a me ka waiwai paepae o ka wili komo hohonu.ʻO ia kekahi o nā kaʻina hana wiliwili alumini alumini.I kēia manawa, ʻaʻole i oʻo ke kaʻina hana a aia i ka pae noiʻi a ʻimi.

ʻOkoʻa ka paʻakikī o ka welding laser no nā alumini alumini like ʻole.ʻO ka hoʻomaʻamaʻa wela ʻole i hoʻoikaika i ka alumini a me ka alumini alumini 1000 series, 3000 series a me 5000 series he weldability maikaʻi;4000 moʻo huila i loa haʻahaʻa māwae;No ka 5000 series alloy, ke ω When (Mg)=2%, the alloy produces cracks.Me ka hoʻonui ʻana o ka magnesium content, hoʻomaikaʻi ʻia ka hana kuʻi ʻana, akā lilo ka ductility a me ka corrosion resistance;2000 moʻo, 6000 moʻo a me 7000 moʻo alloys i ka nui maʻamau i ka wela māwae, ilihune weld kukulu, a me ka nui ho'ēmiʻana ma hope weld elemakule paakiki.

No laila, no ka welding laser o ka alumini alumini, pono ia e hoʻokō i nā kaʻina hana kūpono a koho pono i nā ʻano hana a me nā kaʻina hana e loaʻa ai nā hopena wili maikaʻi.Ma mua o ka wili ʻana, ka mālama ʻana i ka ʻili o nā mea, ka mālama ʻana i nā ʻāpana kaʻina hana welding a me ka hoʻololi ʻana o ka hoʻolālā welding nā ʻano hana maikaʻi.

Ke koho ʻana i nā ʻāpana wili

· Mana laser 3KW.

· Laser wiliwili wikiwiki: 4m / min.ʻO ka wikiwiki o ka welding e pili ana i ka nui o ka ikehu.ʻOi aku ka kiʻekiʻe o ka ikehu, ʻoi aku ka wikiwiki o ka wikiwiki wili.

· Ke uʻi ʻia ka pā (e like me 0.8mm no ka pā ʻaoʻao ʻaoʻao o ka pā waho a me 0.75mm no ka uhi o waho o ka pā), e hoʻomalu ʻia ka ʻaha hui e ke kikowaena, maʻamau 0.05 ~ 0.20mm.Ke emi ka weld ma lalo o 0.15 mm, ʻaʻole hiki ke hoʻoneʻe ʻia ka vapor zinc mai ka ʻaoʻao ʻaoʻao, akā ua hoʻoneʻe ʻia mai ka weld surface, kahi maʻalahi e hana i nā hemahema porosity;Ke ʻoi aku ka nui o ka laula weld ma mua o 0.15 mm, ʻaʻole hiki i ka metala hoʻoheheʻe ke hoʻopiha piha i ke āpau, e hopena i ka lawa ʻole o ka ikaika.Ke like ka mānoanoa weld me ka pā, ʻoi aku ka maikaʻi o nā waiwai mechanical, a ʻo ka laulā weld e pili ana i ke anawaena kikoʻī;ʻO ka hohonu o ka weld e pili ana i ka nui o ka ikehu, ka wikiwiki o ka welding a me ke anawaena.

· ʻO ke kinoea pale he argon, ʻo 25L / min ke kahe, a ʻo ke kaomi hana ʻo 0.15 ~ 0.20MPa.

· ʻO ke anawaena kikoo 0.6 mm.

· Ke kūlana manaʻo: inā he 1mm ka mānoanoa o ka pā, aia ka nānā ʻana ma ka ʻili luna, a ʻo ke kūlana e pili ana i ke ʻano o ka cone.
