Welding Laser na Electron Beam Welding: "High-Tech" maka nrụpụta dị elu

N'ebe dị elu dị ka ikuku ikuku na microelectronics, ịgbado ọkụ ọdịnala siri ike izute ihe achọrọ nke ziri ezi na ntinye miri emi. Laser ịgbado ọkụ na eletrọn doo ịgbado ọkụ pụtara pụtara na ha uru nke "elu ike njupụta, elu nkenke, na ala deformation."

Welding laser:Ọ na-eji a elu-ike laser doo (wavelength 1064nm ma ọ bụ 10.6μm) lekwasịrị anya na workpiece elu. Okpomọkụ ozugbo nwere ike iru ihe karịrị 10,000 Celsius C, na-achọpụta na ọ na-agbaze ngwa ngwa na njikọ nke ọla. Ọ na-egosipụta welds dị warara na obere mpaghara okpomọkụ metụtara, na-eme ka ọ dị mma maka ịgbado ihe ndị nwere mgbidi na obere akụkụ, dị ka brackets igwefoto smartphone na eriri igwe ikuku.

Electron Beam Welding:N'ebe a na-adịghị ahụkebe, a na-eme ngwa ngwa eletrọn ọkụ ma lekwasị anya na bọmbụ na-arụ ọrụ. Site na njupụta ume dị elu dị ka 10 ^ 6-10 ^ 8 W / cm², ọ nwere ike nweta ịgbado ọkụ miri emi na akụkụ ruru 10: 1. Ọ dabara maka ihe ndị nwere ezigbo mgbidi dị ka akụkụ reactor nuklia na ngwa ngwa buru ibu. Agbanyeghị, ọ nwere ọnụ ahịa akụrụngwa dị elu ma chọọ ebe oghere, na-ebute ọnọdụ ngwa ngwa dị ntakịrị.

Ngwa mejupụtara & Ụdị Laser

Usoro ịgbado ọkụ laser ọkọlọtọ gụnyere ihe atọ bụ isi:

Laser Generator: Na-atụgharị ike eletrik ka ọ bụrụ ọkụ laser jikọtara ọnụ.

Sistemụ nnyefe anya: na-eduzi ma na-elekwasị anya n'ọkụ (dịka ọmụmaatụ, fiber optics, enyo na-egosipụta).

Ebe a na-arụ ọrụ: Na-ejikọta ihe ndozi, njikwa ngagharị (robots/linear stages), na nnyefe gas na-echebe.

Usoro dị mkpa na ụkpụrụ nduzi ọrụ

Njikwa oke na-ekpebi ogo weld ozugbo - ọbụlagodi obere ngbanwe nwere ike ibute ntụpọ dị ka porosity ma ọ bụ mgbawa:

(1) Nkwadebe tupu ịgbado ọkụ

Nchacha ihe: Wepu mmanụ, akpịrịkpa oxide, ma ọ bụ mkpuchi site na iji ethanol ma ọ bụ ájá ájá. Maka ihe ndị na-atụgharị uche dị elu (Al, Cu), na-emezi ihe ndị dị n'elu iji belata ntụgharị laser.

Ebe a na-elekwasị anya: Jiri defocus na-adịghị mma (lekwasị anya n'okpuru ebe a na-arụ ọrụ) maka ntinye miri emi; nti defocus (lekwasị anya n'elu) maka mpempe akwụkwọ dị mkpa iji zere ọkụ-site na ọkụ.

Ngwa ụlọ ọrụ & Ọmụmụ Okwu

Ọdịiche nke ịgbado ọkụ laser na-eme ka ihe ọhụrụ dị n'akụkụ niile:

(1) Mwube & Ụlọ ọrụ dị arọ

Structure Steel: Sistemụ ịgbado ọkụ laser-arc nwere isi abụọ weld 20mm+ T-beams na 1.2m/min, na-ebelata nrụrụ site na 50%.

Mbupu ụgbọ mmiri: Sistemụ eduzi Robot nwere okporo ụzọ 7th-axis weld 115mm-thick hull plates na otu ngafe, na-edozi ihe ịma aka "ịgbado ọkụ otu akụkụ, akụkụ abụọ na-akpụ".

(2) Nrụpụta ụgbọ ala

Ịgbado ọkụ nke ọma nke akụrụngwa nnyefe site na iji "teknụzụ njikwa nkwụsi ike nke igodo" iji nweta weld okirikiri na-enweghị ntụpọ.

Laser ịkwa akwa-ịgbado ọkụ nke akụkụ ahụ ụgbọ ala na-ebelata ọnụọgụ akụkụ site na 30% yana ibu site na 15%.

(3) Ike dị elu na ikuku

Ike nuklia: eriri eriri laser nke Ni-28W-6Cr alloy (maka 850ºC mgbawa nnu reactors) na mgbawa mgbawa site na njikarịcha oke.

Aerospace: Welding nke titanium alloy engine agụba nwere obere okpomọkụ emetụtara (HAZ) iji chekwaa ihe onwunwe ike.
