Laser Vuam VS Ultrasonic Hlau Vuam Rau Vaj Huam Sib Luag Hnub Ci
Thawj puag ncig: Cov khoom zoo nkauj zoo nkauj
Laser welding siv lub zog siab nrog lub zog laser kom yaj cov hlau hlau txhawm rau tsim kev sib koom ua ke. Nyob rau hauv lub hnub ci tshav kub nqus nqus phaj vuam, vuam yog ua nyob rau hauv daim ntawv ntawm solder sib txuas nrog qhov sib nrug ntawm 3-5 hli. Laser vuam tsis tas yuav tsum tau muab tso rau qhov haujlwm, qhov hloov kho tag nrho yog qhov me, thiab qhov kev puas tsuaj ntawm cov tshav kub ua kom sov cov txheej tau ua kom me me. Ultrasonic hlau vuam ua rau yoj deformation ntawm qhov chaw vim qhov siab. Txawm hais tias qhov teeb meem saum npoo av tuaj yeem zam tau los ntawm kev teeb tsa rau saum npoo, qhov chaw cim ntawm 3 hli yog tsim nyob rau saum npoo ntawm lub hnub ci tshav kub. Yog li no, cov tsos ntawm cov khoom siv siv laser vuam yog qhov zoo dua li ntawm ultrasonic hlau vuam. Cov kab kev sib tw no, laser welding yog zoo dua li ntawm ultrasonic hlau hlau.
Thib ob: Cia siab ntso
Lub vuam lub zog ntawm laser vuam tsis zoo. Thaum cov kub thiab txias hloov pauv ntau zaus lossis raug rau sab nraud quab yuam, cov leeg txuas yog yooj yim tawg. Ultrasonic hlau vuam yog mus rau superimpose ob yam khoom uas yuav tsum tau welded los ntawm kev ntsug siab, ua ke nrog ultrasonic kev co thiab siab los ua qhov khoom sib txuas. Lub sij hawm sib txuas yog luv thiab cov ntu sib txuam tsis tsim cov qauv casting tsis xws luag, yog li ntawd txoj haujlwm vuam yog yam zoo ib yam thiab ruaj khov, thiab cov hlau ultrasonic. Tsis muaj qhov muaj pob txha tawg tom qab 90 degree ntsug khoov ntsuas. Qhov kab ntawm kev sib tw no, ultrasonic hlau vuam yog zoo dua li laser welding.
Thib peb: Cov ua haujlwm thermal
Laser welding tuaj yeem hloov kho lub cev kev teeb tsa ntawm lub nruas yog welded, yog li cuam tshuam nws cov hluav taws xob lossis thermal conductivity. Ntxiv mus, lub laser vuam ua rau thaj chaw me me thaum sib sau ua ke ntawm cov hlau ntawm lub hnub ci sau thiab lub raj tooj liab, uas cuam tshuam rau cov cua sov ua kom zoo. Ultrasonic hlau tsis muaj qhov teeb meem no. Ultrasonic welding tsis tshua muaj qhov hloov mus rau qhov kub thiab txias thiab tsis hloov cov qauv hlau. Yog li no, hluav taws xob hluav taws xob los yog cov thermal conductivity tom qab welding yog zoo heev, thiab hluav taws xob resistivity yog tsawg kawg lossis ze li xoom. Ultrasonic hlau vuam tau dhau los ua qhov kev xaiv zoo tshaj plaws rau vuam conductive thiab cov ntaub ntawv thermal conductive. Qhov kev ua tau zoo no tuaj yeem pom tseeb ua cov duab hlau ua haujlwm ntawm cov kab sib tw hnub ci. Qhov zoo dua uas tsis tuaj yeem ua tiav. Raws li kev ntsuam xyuas, cov khoom lag luam ultrasonic hlau vuam yog kwv yees li 3% siab dua li cov laser vuam conduction efficiency (ntawd yog, dej kub yog li 3% raws li kev ua haujlwm tib yam). Qhov kab lus ntawm kev sib tw no, ultrasonic hlau vuam yog qhov zoo dua li kev ua haujlwm ntawm laser hlau.
Plaub round : Zog noj
Raws li tus neeg sawv cev cov khoom siv hluav taws xob tsawg-txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, kev tiv thaiv dej hnub ci tau dav dav los ntawm zej zog thiab cov neeg siv khoom, thiab kev siv lub zog siv hluav taws xob hauv cov txheej txheem ntau lawm kuj tau txais kev mloog zoo. Vuam ntawm hnub ci lolus yog ib qho ntawm lawv. Los ntawm qhov kev sib piv sib piv ntawm cov ntsiab lus ntawm vuam, nws tuaj yeem paub tias ultrasonic hlau vuam tuaj yeem txo qhov kub thiab txias ntawm cov khoom siv (qhov kub ntawm qhov chaw weld tsis tshaj 50% ntawm qhov tsis sib xws kub ntawm lub hlau tsis txuas), kom cov qauv hlau tsis hloov, yog li nws tsis Nws yuav anneal hlau workpieces tsis muaj dej txias. Hais txog kev siv lub zog, ultrasonic vuam tuaj yeem ua tau ntawm tib lub hlau thiab ntau hom hlau, uas yog cov siv hluav taws xob tsawg dua li cov tshuab hluav taws xob. Qhov kab ntawm kev sib tw no, ultrasonic hlau vuam yog zoo dua li laser welding.
Thib tsib puag ncig : Nqi
1. Tus nqi ntawm cov khoom siv: thoob ntiaj teb, tus nqi ntawm ultrasonic vuam tshuab thiab laser vuam tshuab yog qhov sib npaug. Kev them nqi khoom siv ntawm ib qho cuab yeej siv ntawm tshuab hlau tshuab ultrasonic yog qis dua tus nqi ntawm tshuab laser vuam. Qhov muab ua piv txwv ntawm ob feem ntau yog 300,000: 10,000. (Tam sim no tus nqi ntawm kev siv lub tshuab welding laser hauv tsev kuj tseem poob qis, kwv yees li 700,000) Lub tshuab welding laser feem ntau muaj ob lub taub hau vuam, thiab lub tshuab ultrasonic feem ntau muaj ib lub taub hau vuam. Rau tib lub peev xwm ntau lawm, ob lub tshuab ultrasonic welding tau muab piv nrog ib lub tshuab laser vuam.
2.Cov ntawm kev siv: Ua ntej, laser vuam yog qhov tsim nyog rau cov khoom siv tuab, xws li vuam aluminium. Lub thickness ntawm txhuas phaj feem ntau xaiv los ua 0.4 hli, thaum ultrasonic welding yog haum rau cov khoom nyias, xws li txhuas phaj, feem ntau 0.2-0.3mm. Hais txog cov ntaub ntawv vuam, ultrasonic yog qhov zoo dua. Thib ob, tus nqi ntawm consumables, cov khoom siv hluav taws xob rau cov xaim hluav taws xob yog xenon lub teeb thiab lim lub thawv, thiab cov ultrasonic consumables yog vuam taub hau. Feem ntau, laser vuam siv tau yog pheej yig dua li ultrasonic.
