5 Cov Teeb Meem Zoo thiab Kev daws teeb meem ntawm Laser Vuam

Ntsib qhov xwm txheej sib txawv rau laser welder

Nrog kev ua haujlwm siab, kev raug siab, kev vuam zoo, kev sib koom ua ke yooj yim, thiab lwm yam zoo, laser vuam siv dav hauv ntau yam lag luam thiab ua lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab kev tsim khoom ntawm cov hlau vuam, suav nrog hauv tub rog, kev kho mob, aerospace, 3C qhov chaw pib, hlau ntawv kho tshuab, lub zog tshiab, khoom siv huv, thiab lwm yam lag luam.

Txawm li cas los xij, yog tias tsis paub txog nws lub hauv paus ntsiab lus thiab thev naus laus zis, txhua txoj kev vuam yuav tsim qee qhov tsis zoo lossis cov khoom tsis zoo, laser vuam tsis muaj qhov tshwj xeeb. Tsuas yog nkag siab zoo txog cov qhov tsis zoo no, thiab kawm paub yuav ua li cas kom tsis txhob muaj cov qhov tsis zoo no, kom ua si zoo dua ntawm laser vuam, ua kom zoo nkauj, thiab cov khoom zoo. Cov kws ua haujlwm los ntawm kev paub dhau los ntev, tau sau qee qhov tsis zoo ntawm kev vuam, rau cov npoj yaig hauv kev lag luam siv!

1. Cov kab nrib pleb

Cov kab nrib pleb uas tsim tawm hauv kev vuam txuas ntxiv mus los ntawm laser feem ntau yog cov kab nrib pleb kub, xws li cov kab nrib pleb crystallization, cov kab nrib pleb liquefied, thiab lwm yam. Qhov laj thawj tseem ceeb yog tias qhov vuam ua rau muaj lub zog loj ua ntej cov hlau khov tag nrho. Siv lub tshuab pub hlau los sau cov hlau lossis ua kom cov hlau sov ua ntej tuaj yeem txo lossis tshem tawm cov kab nrib pleb uas pom thaum vuam laser.

2. Cov qhov hauv weld

Qhov porosity yog ib qho yooj yim ua rau muaj qhov tsis zoo hauv kev vuam laser. Feem ntau, lub pas dej vuam laser tob thiab nqaim, thiab cov hlau feem ntau coj cua sov zoo heev thiab ceev heev. Cov pa roj tsim tawm hauv cov kua dej molten tsis muaj sijhawm txaus los tawm ua ntej cov hlau vuam txias. Cov xwm txheej zoo li no yooj yim ua rau muaj qhov pores. Tab sis kuj vim tias thaj chaw kub ntawm laser vuam me me, cov hlau tuaj yeem txias sai heev, qhov porosity tshwm sim hauv kev vuam laser feem ntau me dua li kev vuam fusion ib txwm muaj. Kev ntxuav qhov chaw ua haujlwm ua ntej vuam tuaj yeem txo qhov kev nyiam ntawm qhov pores, thiab qhov kev taw qhia ntawm kev tshuab kuj tseem yuav cuam tshuam rau kev tsim cov qhov pores.

3. Lub dej ntws

Yog koj vuam cov hlau ua haujlwm sai dhau, cov hlau kua tom qab lub qhov taw rau hauv nruab nrab ntawm qhov vuam yuav tsis muaj sijhawm los faib dua. Kev khov ntawm ob sab ntawm qhov vuam yuav tsim ib qho tom. Thaum qhov sib txawv ntawm ob daim haujlwm loj dhau, yuav tsis muaj cov hlau yaj txaus rau kev caulking, uas yog li ntawd qhov vuam ntug tom kuj yuav tshwm sim. Thaum kawg ntawm laser vuam, yog tias lub zog poob sai dhau, lub qhov yooj yim tawg thiab ua rau muaj qhov tsis zoo sib xws ntawm kev vuam. Kev sib npaug zoo dua ntawm lub zog thiab kev txav mus los ceev rau kev teeb tsa laser vuam tuaj yeem daws qhov teeb meem ntawm kev tom ntug.

4. Txiav hauv qab

Qhov dej txaws uas tsim los ntawm kev vuam laser cuam tshuam loj heev rau qhov zoo ntawm qhov chaw vuam thiab tuaj yeem ua rau lub lens puas tsuaj thiab ua rau puas tsuaj. Qhov dej txaws muaj feem cuam tshuam ncaj qha rau qhov ceev ntawm lub zog, thiab tuaj yeem txo tau los ntawm kev txo lub zog vuam kom zoo. Yog tias qhov nkag mus tsis txaus, qhov ceev ntawm kev vuam tuaj yeem txo tau.

5. Lub pas dej ua los ntawm cov dej khov uas yaj tag

Yog tias qhov ceev ntawm kev vuam qeeb, lub pas dej ua los ntawm cov hlau loj thiab dav, cov hlau ua los ntawm cov hlau ntau ntxiv, thiab qhov nro ntawm qhov chaw nyuaj rau tswj cov hlau ua kua hnyav, qhov chaw vuam yuav tog, tsim kev tawg thiab qhov av. Lub sijhawm no, nws yog qhov tsim nyog los txo qhov ceev ntawm lub zog kom tsim nyog kom tsis txhob muaj kev tawg ntawm lub pas dej ua los ntawm cov hlau.
