Thawj puag ncig: khoom lag luam zoo nkauj PK
Laser welding siv lub zog qhov siab laser los ua kom yaj cov hlau txuas ua qhov sib koom ua ke. Hauv lub hnub ci tshav kub-nqus phaj vuam, nws yog welded nyob rau hauv daim ntawv ntawm solder sib txuas nrog qhov sib nrug ntawm 3-5 hli. Laser vuam tsis tas yuav tsum tau ua rau qhov cuam tshuam rau qhov chaw ua haujlwm kom tau txais lub sijhawm, qhov kev hloov kho tag nrho yog qhov me, thiab qhov kev puas tsuaj rau lub tshav kub cov txheej txheej ua kom me me, thiab ultrasonic hlau vuam ua rau vuam ntom ntawm qhov chaw ntawm daim ntawv vim lub siab, txawm hais tias nws tuaj yeem zam dhau kev npuaj npoo. Deformation, tab sis nws tseem yuav ua lub cim weld ntawm kwv yees li ntawm 3 hli nyob rau saum npoo ntawm hnub ci kev nqus nyiaj. 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 round: cov nyhuv tsis ua hauj lwm PK
Cov chaw vuam vias ntawm laser vuam yog qis dua. 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 koom ua ke tsis tsim cov qauv casting tsis xws luag, yog li lub vuam txoj haujlwm yog qhov tsis sib xws thiab ruaj khov, thiab cov hlau ultrasonic tsis muaj qhov tawg tom qab 90 degree ntsug khoov xeem. Qhov kab ntawm kev sib tw no, ultrasonic hlau vuam yog zoo dua li laser welding.
Round 3: Thermal Kev Coj Ua PK
Kev siv laser vuam yuav hloov lub cev qauv ntawm lub nruas welded, yog li cuam tshuam nws cov hluav taws xob lossis thermal conductivity, thiab cov laser vuam ua rau thaj chaw me me ntawm kev sib cais ntawm cov hlau phaj thiab tooj liab raj ntawm lub hnub ci, uas cuam tshuam rau tshav kub hloov ua haujlwm tau zoo. Ultrasonic hlau tsis muaj qhov teeb meem no. Ultrasonic welding tuaj yeem txo qhov kub thiab txias ntawm cov khoom, kom cov qauv hlau tsis hloov, yog li cov hluav taws xob hluav taws xob lossis thermal conductivity tom qab vuam yog zoo heev, qhov hluav taws xob resistivity tsawg kawg lossis ze li xoom, thiab ultrasonic hlau vuam tau dhau los ua ib qho kev coj ua thiab cov khoom ua kom kub ceev. Qhov kev xaiv zoo tshaj plaws, qhov kev ua tau zoo no ntawm lub tiaj hnub ci tus neeg sau tau tuaj yeem pom tseeb ua qhov zoo uas cov hlau laser 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% nyob rau tib qho kev ua haujlwm qub). Qhov kab lus ntawm kev sib tw no, ultrasonic hlau vuam yog qhov zoo dua li kev ua haujlwm ntawm laser hlau.
Hloov 4: Lub Zog Siv Lub Zog PK
Raws li tus neeg sawv cev cov khoom lag luam ntawm kev siv hluav taws xob tsawg-txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, cov cuab yeej siv dej hnub ci tau dav dav los ntawm zej zog thiab cov neeg siv khoom, thiab lub zog siv hluav taws xob hauv cov txheej txheem ntau lawm kuj tau txais kev mloog. Lub vuam ntawm lub 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.
Muab 5: Nqi PK
Ua ntej, 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 ultrasonic hlau vuam tshuab yog qis dua tus nqi ntawm tshuab laser vuam. Qhov txiaj ntsig kev sib kis ntawm ob feem ntau yog 300,000: 1 lab (tam sim no kev lag luam hauv laser vuam) Tus nqi ntawm lub tshuab kuj tseem poob qis, poob qis txog li 700,000. Lub tshuab welding laser feem ntau muaj ob lub hau vuam 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.
Thib ob, tus nqi ntawm kev siv: Ua ntej, laser vuam yog qhov tsim nyog rau cov khoom siv tuab, xws li vuam txhuas, cov tuab ntawm txhuas phaj feem ntau xaiv los ua 0.4 hli, thiab ultrasonic vuam yog tsim rau cov khoom nyias, xws li txhuas phaj, feem ntau 0.2-0.3mm tuaj yeem xaiv tau. Hais txog cov ntaub ntawv vuam, ultrasonic tsis muaj qhov zoo dua. Thib ob, tus nqi ntawm cov khoom siv, cov khoom siv hluav taws xob rau cov xaim hluav taws xob yog xenon lub teeb roj thiab cov roj lim, thiab lwm yam, thiab cov ultrasonic consumables yog vuam taub hau. Feem ntau, laser vuam consumables yog qhov pheej yig tshaj li cov khoom siv ntawm ultrasonics.
