Uru na ọghọm dị na Welding Laser nke Aluminom Alloy

Mgbe laser ịgbado ọkụ aluminum alloy, dị nnọọ ka ịgbado ọkụ nke galvanized ígwè efere, ọtụtụ pores na cracks ga-emepụta n'oge ịgbado ọkụ usoro, nke ga-emetụta ịgbado ọkụ àgwà.Aluminom mmewere nwere obere ionization ume, ogbenye ịgbado ọkụ kwụsie ike, na ga-eme ka ịgbado ọkụ akwụsị.Na mgbakwunye na usoro ịgbado ọkụ dị elu, a ga-emepụta aluminum oxide na aluminom nitride na usoro dum, na-ebute mmetọ na gburugburu ebe obibi.

Otú ọ dị, aluminom alloy efere elu nwere ike polished tupu ịgbado ọkụ ka iwelie ya absorption nke laser ike;A ga-eji gas inert mee ihe n'oge ịgbado ọkụ iji gbochie oghere ikuku.

Laser arc ngwakọ ịgbado ọkụ nke aluminum alloy edozila nsogbu nke laser ịgbado ọkụ ike, absorption nke laser doo n'elu nke aluminum alloy na ọnụ ụzọ uru nke miri penetration ịgbado ọkụ.Ọ bụ otu n'ime usoro ịgbado ọkụ aluminom na-ekwe nkwa.Ka ọ dị ugbu a, usoro a etobeghị ma dị na nyocha na nyocha.

Ihe isi ike nke ịgbado ọkụ laser dị iche iche maka alloys aluminum dị iche iche.The dịghị okpomọkụ ọgwụgwọ ike aluminum na aluminum alloy 1000 usoro, 3000 usoro na 5000 usoro nwere ezi weldability;4000 usoro alloy nwere nnọọ ala mgbape uche;Maka usoro alloy 5000, mgbe ω Mgbe (Mg) = 2%, alloy na-emepụta mgbawa.Site na mmụba nke ọdịnaya magnesium, arụ ọrụ ịgbado ọkụ na-akawanye mma, mana ductility na nguzogide corrosion dara ogbenye;2000 usoro, 6000 usoro na 7000 usoro alloys nwere nnukwu ọchịchọ na-ekpo ọkụ cracking, ogbenye weld guzobe, na a ịrịba mbelata post weld ịka nká ike.

Ya mere, maka ịgbado ọkụ laser nke aluminom alloy, ọ dị mkpa ịgbaso usoro usoro kwesịrị ekwesị ma họrọ usoro ịgbado ọkụ n'ụzọ ziri ezi na usoro iji nweta nsonaazụ ịgbado ọkụ dị mma.Tupu ịgbado ọkụ, elu ọgwụgwọ nke ihe, akara nke ịgbado ọkụ usoro parameters na mgbanwe nke ịgbado ọkụ Ọdịdị bụ niile irè ụzọ.

Nhọrọ nke ịgbado ọkụ parameters

· ike Laser 3KW.

· Ọsọ ịgbado ọkụ laser: 4m/min.Ọsọ ịgbado ọkụ na-adabere na njupụta ike.Nke dị elu nke ike njupụta, ngwa ngwa ịgbado ọkụ ọsọ.

· Mgbe efere na-galvanized (dị ka 0.8mm maka akụkụ mgbidi dị n'elu efere na 0.75mm maka n'elu mkpuchi elu efere), a na-achịkwa mkpochapụ mgbakọ site na etiti, n'ozuzu 0.05 ~ 0.20mm.Mgbe weld ahụ na-erughị 0.15 mm, a pụghị iwepụ vapor zinc site na ọdịiche dị n'akụkụ, ma a na-ewepụ ya n'elu weld, nke dị mfe ịmepụta ntụpọ porosity;Mgbe obosara weld karịrị 0.15 mm, igwe a wụrụ awụ enweghị ike mejupụta oghere ahụ kpamkpam, na-akpata enweghị ike zuru oke.Mgbe weld ọkpụrụkpụ bụ otu ihe ahụ dị ka nke efere, na n'ibu Njirimara ndị kasị mma, na weld obosara dabere na-elekwasị anya dayameta;The weld omimi dabere na ike njupụta, ịgbado ọkụ ọsọ na-elekwasị anya dayameta.
