Yog tias cov khoom siv aluminium thiab aluminium alloy lossis cov khoom siv tau welded khov kho thiab cov vuam zoo nkauj, tau kawg, nws yog qhov sib cais ntawm aluminium alloy laser vuam tshuab. Txawm hais tias cov nyhuv laser vuam yog qhov zoo, aluminium thiab aluminium alloy muaj cov yam ntxwv ntawm kev xav tau siab thiab kev nyiam me me. Tseem muaj teeb meem hauv kev vuam, yog li them sai sai rau 3 lub ntsiab lus thaum laser vuam.
Peb paub tias aluminium thiab aluminium alloys yog cov khoom siv dav tshaj plaws ntawm cov khoom siv hlau tsis muaj hlau. Cov hlau ua tau zoo heev. Piv nrog rau cov khoom siv hlau dav dav, lawv muaj lub zog siab thiab zoo corrosion kuj, thiab tsuas yog siv tom qab hlau. Nws tau dav siv nyob rau hauv aviation, aerospace, tsheb, machinery manufacturing, shipbuilding thiab tshuaj industries. Nrog rau kev loj hlob sai ntawm kev lag luam, qhov kev thov rau aluminium alloy welded structural qhov chaw yog nce. Txog tam sim no, aluminium alloy yog cov khoom siv alloy nrog ntau daim ntawv thov, thiab nws yog qhov kev thov loj hauv kev lag luam laser vuam.
1. Thaum laser vuam aluminium alloy, lub teeb pom kev tshwm sim nyob rau saum npoo ntawm aluminium alloy, vim hais tias aluminium alloy yog cov hlau tsis muaj hlau, uas muaj qhov muaj zog reflectivity rau ntau hom teeb. Cov hlau uas tsis yog-ferrous xws li aluminium alloy muaj kev cuam tshuam siab rau laser Thiab me me nqus cov nqi. Yog li ntawd, ua ntej welding aluminium alloy, qhov saum npoo ntawm aluminium alloy yuav tsum tau ntxuav kom tshem tawm cov roj stains ntawm qhov chaw. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv kev tawg thiab lwm yam kev hem thawj ntawm kev nyab xeeb los ntawm oxidation thaum lub sij hawm vuam, nws tseem yuav tsum tau ua tib zoo ntxuav cov oxide zaj duab xis ntawm cov hlau nto thiab tshem tawm cov oxide zaj duab xis kom tiav.
2. Ua kom tag nrho cov kev npaj thaum laser vuam aluminium alloys, vim hais tias txhuas alloys muaj cov yam ntxwv ntawm kev ua cus ciav thiab yooj yim oxidized, thiab ib tug loj npaum li cas ntawm plua plav thiab noo noo yog yooj yim txuas rau lawv qhov chaw. Yog li ntawd, nyob rau hauv cov txheej txheem vuam, yog tias tsis txaus Rau kev npaj, cov khoom uas txuas rau saum npoo yog yooj yim nyob rau hauv cov hlau alloy nto nrog lub vuam ceev ntawm lub laser, yog li cuam tshuam rau qhov zoo ntawm aluminium alloy thiab vuam nyhuv.
3. Tsis tas li ntawd, hlau tag nrho muaj thermal conductivity, yog li txhuas alloys kuj muaj zog thermal conductivity. Nws yog ib qho yooj yim los cuam tshuam lub laser los yog sai sai dissipate lub tshav kub ntawm lub laser thaum vuam nrog laser, uas nws thiaj li ua rau aluminium alloy Vuam ua tsis tau tejyam. Yog li ntawd, thaum laser vuam alloys alloys, peb yuav tsum tau ua kom pom zoo rau kev xav txog thiab ua kom muaj zog heev ntawm lub sijhawm dhau los, yog li ntawd kev xav tau ntxiv thiab lwm yam teeb meem.
