Dab tsi yuav tsum tau ceev faj thaum lub sij hawm laser vuam?
Raws li ib tug ntawm cov niaj hnub advanced manufacturing technologies, laser welding tau txais ntau daim ntawv thov nyob rau hauv ntau lub teb xws li aerospace, automotive manufacturing, thiab hluav taws xob khoom vim nws high precision thiab efficiency. Txawm li cas los xij, kev ua tiav siab - laser vuam zoo yuav tsum tau ua tib zoo saib xyuas ntau yam tseem ceeb thaum lub sijhawm ua haujlwm.
Kev npaj txhij txhua yog qhov tseem ceeb
Kev tshuaj xyuas cov cuab yeej yog lub luag haujlwm tseem ceeb ua ntej laser vuam. Cov khoom tseem ceeb xws li lub tshuab hluav taws xob laser, kho qhov muag, thiab lub tshuab ua kom txias yuav tsum tau kuaj xyuas kom zoo. Piv txwv li, txheeb xyuas qhov ruaj khov ntawm lub tshuab hluav taws xob laser lub zog tso zis; Kev hloov pauv ntau dhau tuaj yeem ua rau qhov tsis sib haum xeeb ntawm qhov tob thiab cuam tshuam qhov vuam zoo. Nyob rau tib lub sijhawm, tshuaj xyuas cov tsom iav kho qhov muag rau khawb lossis cov kab mob, vim tias qhov tsis zoo tuaj yeem cuam tshuam cov nqaj laser lossis cuam tshuam kev tsom, yog li txo qhov vuam zog ceev.
Kev npaj workpiece yog qhov tseem ceeb sib npaug. Xaiv qhov tsim nyog ua ntej- txoj kev kho mob raws li cov khoom siv ntawm cov khoom ua haujlwm. Rau cov khoom siv hlau nrog cov roj paug lossis cov oxide txheej rau ntawm qhov chaw, kev tu kom huv thiab polishing yuav tsum tau ua kom ntseeg tau tias laser zog nkag tau zoo thaum vuam thiab tiv thaiv qhov tsis xws luag los ntawm impurities. Tsis tas li ntawd, kev sib dhos precision yog qhov tseem ceeb; Qhov tsis raug cai tso cai rau lub zog laser dissipate ntawm lub interface, tiv thaiv kev tsim cov pas dej ua kom zoo thiab ua rau muaj qhov tsis xws luag xws li tsis tiav fusion.
Cov txheej txheem ua haujlwm yuav tsum muaj kev txiav txim siab nruj
Parameter configuration yog lub hauv paus tseem ceeb ntawm kev ua haujlwm laser vuam. Cov tsis xws li laser fais fab, vuam ceev, thiab mem tes zaus yuav tsum tau kho raws li tej yam xws li cov khoom workpiece thiab thickness. Noj stainless hlau phaj vuam ua piv txwv: kev teeb tsa hluav taws xob ntau dhau tuaj yeem ua rau overheating, deformation, los yog kub hnyiab tau - los ntawm lub workpiece; conversely, tsis txaus lub zog tiv thaiv cov khoom txaus melting, ua rau tsis tiav fusion. Kev kub ceev vuam ntau dhau ua rau lub pas dej molten kom solidify sai heev, ntxiab gases thiab tsim porosity. Hloov pauv, qeeb qeeb qeeb ua rau muaj cua sov ntau dhau - thaj chaw cuam tshuam, cuam tshuam cov khoom ua haujlwm. Yog li ntawd, cov neeg ua haujlwm yuav tsum paub qhov zoo tshaj plaws parameter sib xyaw ua ke rau cov khoom sib txawv thiab cov txheej txheem yuav tsum tau ua los ntawm kev sim ntau thiab kev xyaum.
Thaum vuam, ua tib zoo saib xyuas qhov vuam mob. Saib xyuas cov duab thiab xim ntawm lub pas dej molten; lub pas dej molten ib txwm yuav tsum tshwm sim ua kua nrog lub cev tsis tu ncua. Yog hais tias lub pas dej molten zoo nkaus li npub los yog ntau dhau spatter tshwm sim, nws yuav qhia tau tias qhov teeb meem tsis raug lossis cov khoom siv tsis raug, yuav tsum tau kho tam sim ntawd lossis kaw rau kev tshuaj xyuas. Tib lub sijhawm, ua tib zoo saib xyuas qhov chaw vuam, tswj xyuas qhov chaw ua haujlwm huv thiab qhuav kom tsis txhob muaj impurities xws li plua plav lossis ya raws los ntawm kev cuam tshuam cov vuam zoo.
Kev ceev faj txog kev nyab xeeb yog qhov tseem ceeb
Lub teeb laser khaus tsim thaum lub sij hawm vuam ua rau muaj kev phom sij loj rau qhov muag thiab tawv nqaij. Cov neeg ua haujlwm yuav tsum hnav cov tsom iav tshwj xeeb laser kev nyab xeeb nrog cov wavelengths txuam nrog lub tshuab hluav taws xob lub tshuab hluav taws xob kom ua tau zoo los thaiv cov hluav taws xob ncaj qha thiab cuam tshuam. Tsis tas li ntawd, cov khaub ncaws tiv thaiv thiab hnab looj tes yuav tsum tau hnav los tiv thaiv cov tawv nqaij kub hnyiab los ntawm kev raug laser lossis molten slag splatter.
Cov cuab yeej ua kom muaj qhov kub thiab txias thaum lub sijhawm ua haujlwm, xav kom lub tshuab ua kom txias ua haujlwm kom zoo. Tsis tu ncua tshuaj xyuas cov dej txias txias thiab qhov kub thiab txias kom ntseeg tau tias lub kaw lus txo qis cov cuab yeej kub, tiv thaiv kev puas tsuaj los yog xwm txheej tshwm sim los ntawm overheating. Tsis tas li ntawd, cov hluav taws tua hluav taws yuav tsum muaj nyob rau hauv qhov chaw ua hauj lwm los daws cov hluav taws kub los ntawm hluav taws xob tsis zoo los yog vuam sparks.
Ncej -Kev ua haujlwm yuav tsum tau ua tib zoo saib xyuas
Tom qab welding, ua kev soj ntsuam zoo ntawm cov welds. Tsis yog-kev kuaj kev puas tsuaj xws li X- kev tshuaj xyuas hluav taws xob lossis kuaj ultrasonic tuaj yeem siv los kuaj xyuas qhov tsis xws luag xws li porosity lossis tawg. Rau qhov pom kev zoo, tshuaj xyuas seb cov hlaws hlaws puas muaj qhov tsim tau zoo, qhov chaw du thiab tiaj tus, thiab seb puas muaj qhov tsis xws luag xws li undercut lossis tsis muaj fusion.
Raws li qhov yuav tsum tau ua ntawm daim ntawv thov, kev tshaj tawm -weld kev kho mob xws li kev sib tsoo, polishing, los yog kev kho cua sov yuav tsim nyog los txhim kho weld kev ua tau zoo thiab zoo li.
Nyob rau hauv cov ntsiab lus, laser vuam yog ib tug heev technical txheej txheem. Kev ua kom zoo thiab kev nyab xeeb yuav tsum muaj kev tswj xyuas nruj nyob rau txhua theem -kev npaj, kev ua haujlwm, kev tiv thaiv kev nyab xeeb, thiab tom qab- kev kho vuam- kom ua tau zoo, siab - vuam ntau lawm.
