5 Laser Vuam Zoo Teebmeem & Kev daws teeb meem

Ntsib cov xwm txheej sib txawv rau laser welder

Nrog kev ua haujlwm siab, siab precision, zoo vuam nyhuv, yooj yim tsis siv neeg kev koom ua ke, thiab lwm yam zoo, laser vuam yog dav siv nyob rau hauv ntau yam industries thiab plays ib tug tseem ceeb luag hauj lwm nyob rau hauv cov hlau welding industrial ntau lawm thiab manufacturing, nrog rau cov tub rog, kev kho mob, aerospace, 3C. nws pib qhov chaw, mechanical sheet hlau, tshiab zog, huv si kho vajtse, thiab lwm yam lag luam.

Txawm li cas los xij, txhua txoj kev vuam yog tias tsis paub txog nws txoj cai thiab thev naus laus zis, yuav tsim cov khoom tsis xws luag lossis cov khoom tsis raug, laser vuam tsis muaj qhov tshwj xeeb. Tsuas yog kev nkag siab zoo ntawm cov teeb meem no, thiab kawm paub yuav ua li cas kom tsis txhob muaj cov teeb meem no, ua kom zoo dua cov nqi ntawm laser vuam, ua kom zoo nkauj zoo nkauj, thiab cov khoom zoo. Cov kws tshaj lij los ntawm kev paub ntev ntev, suav nrog qee qhov kev sib txuas ntawm cov kev daws teeb meem, rau kev lag luam cov npoj yaig siv!

1. Kev tawg

Cov kab nrib pleb uas tsim nyob rau hauv laser nruam vuam feem ntau yog kub tawg, xws li crystallization tawg, liquefied tawg, thiab lwm yam. Lub ntsiab yog vim li cas lub weld tsim ib tug loj shrinkage quab yuam ua ntej lub tiav solidification. Siv cov hlau feeder los sau cov xov hlau los yog preheating cov hlau daim tuaj yeem txo lossis tshem tawm cov kab nrib pleb uas pom nyob rau hauv laser vuam.

2.Pores hauv weld

Porosity yog ib qho teeb meem yooj yim hauv laser vuam. Tsis tu ncua lub laser vuam pas dej yog qhov tob thiab nqaim, thiab cov hlau feem ntau ua cov cua sov zoo heev thiab ceev ceev. Cov roj uas ua rau hauv lub pas dej ua kua molten tsis muaj sijhawm txaus kom khiav tawm ua ntej vuam hlau txias. Xws li cov ntaub ntawv yog ib qho yooj yim uas yuav ua rau tsim ntawm pores. Tab sis kuj vim hais tias lub laser vuam tshav kub cheeb tsam yog me me, cov hlau yuav txias sai sai, qhov tshwm sim porosity pom nyob rau hauv laser vuam yog feem ntau me dua cov tsoos fusion vuam. Kev ntxuav lub workpiece nto ua ntej vuam tuaj yeem txo qhov nyiam ntawm qhov hws, thiab cov kev taw qhia ntawm tshuab kuj tseem cuam tshuam rau kev tsim cov pores.

3.Txoj kev

Yog tias koj welding cov hlau workpiece ceev heev, cov kua hlau tom qab lub qhov taw qhia mus rau qhov nruab nrab ntawm weld tsis muaj sij hawm los faib. Solidifying ntawm ob sab ntawm weld yuav tsim ib qho tom. Thaum qhov sib txawv ntawm ob daim ntawm kev ua haujlwm loj dhau lawm, yuav muaj cov hlau tsis txaus rau kev ua kom tawg, qhov twg vuam ntug tom yuav tshwm sim. Nyob rau theem kawg ntawm kev siv laser vuam, yog tias lub zog poob sai heev, lub qhov yog qhov yooj yim kom tawg thiab ua rau cov vuam zoo sib xws. Lub zog sib npaug zoo dua thiab txav nrawm rau laser vuam chaw tuaj yeem daws cov cim ntawm ntug tom.

4. Txom nyem

Cov txaws ua los ntawm laser vuam cuam tshuam rau qhov vuam zoo thiab tuaj yeem paug thiab ua rau lub lens puas. Lub spatter yog ncaj qha ntsig txog lub zog ceev, thiab tuaj yeem txo qis los ntawm kev txo cov vuam zog kom zoo. Yog tias qhov nkag mus tsis txaus, qhov vuam ceev tuaj yeem raug txo.

5.Lub cev qhuav dej ntawm lub pas dej molten

Yog tias qhov vuam nrawm nrawm, lub pas dej molten loj thiab dav, cov hlau molten nce, thiab qhov nro ntawm qhov nyuaj yog qhov nyuaj los tswj cov kua hlau hnyav, qhov chaw weld yuav tog, ua rau lub cev qhuav dej thiab lub qhov dej. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum tau txo lub zog ceev kom tsim nyog kom tsis txhob muaj kev sib tsoo ntawm lub pas dej molten.
