Cov Kev Tsis Zoo Hauv Laser Welding Thiab Yuav Ua Li Cas Thiaj Daws Tau Lawv

Kev vuam laser yog ib txoj kev ua haujlwm zoo thiab meej heev uas siv rau ntau yam lag luam. Txawm li cas los xij, qee qhov tsis zoo xws li tawg, porosity, spatter, hlawv-dhau, thiab undercutting tuaj yeem tshwm sim thaum lub sijhawm ua haujlwm. Kev nkag siab txog cov laj thawj ntawm cov teeb meem no thiab lawv cov kev daws teeb meem yog qhov tseem ceeb rau kev txhim kho qhov zoo ntawm kev vuam thiab xyuas kom meej tias cov txiaj ntsig ntev. Hauv qab no yog cov teeb meem tseem ceeb pom hauv kev vuam laser thiab yuav ua li cas daws lawv:

1. Cov kab nrib pleb

Ua rau: Feem ntau cov kab nrib pleb tshwm sim vim muaj zog ntau dhau ua ntej lub pas dej vuam khov tag. Lawv feem ntau cuam tshuam nrog cov kab nrib pleb kub, xws li cov kab nrib pleb khov lossis cov kab nrib pleb ua kua.

Kev daws teeb meem: Txhawm rau kom txo lossis tshem tawm cov kab nrib pleb, ua ntej ua kom sov lub workpiece thiab ntxiv cov khoom siv filler tuaj yeem pab faib cov cua sov kom sib npaug, yog li txo qhov kev ntxhov siab thiab tiv thaiv cov kab nrib pleb.

2. Qhov porosity

Ua rau: Kev vuam laser ua rau muaj lub pas dej vuam tob thiab nqaim uas txias sai. Cov pa roj uas tsim tawm hauv lub pas dej yaj tsis muaj sijhawm txaus los tawm, ua rau muaj cov qhov roj (qhov hws) hauv qhov vuam.

Kev daws teeb meem: Yuav kom txo qhov porosity, ntxuav qhov chaw ua haujlwm kom huv si ua ntej vuam. Tsis tas li ntawd, kev kho qhov kev taw qhia ntawm cov pa roj tiv thaiv tuaj yeem pab tswj cov pa roj ntws thiab txo qhov tshwm sim ntawm cov qhov pores.

3. Spatter

Ua rau: Cov dej tawg yog muaj feem cuam tshuam ncaj qha rau lub zog ceev. Thaum lub zog ceev siab dhau, cov khoom siv yuav ua pa ntau heev, ua rau cov khoom siv yaj tawg tawm ntawm lub pas dej vuam.

Kev daws teeb meem: Txo lub zog vuam thiab kho qhov ceev vuam kom haum dua. Qhov no yuav pab tiv thaiv kom cov khoom tsis txhob vaporized ntau dhau thiab txo qhov spatter.

4. Hlawv-dhau

Ua rau: Qhov teeb meem no tshwm sim thaum lub vuam ceev dhau, ua rau cov hlau ua kua tsis tuaj yeem faib rov qab kom raug. Nws kuj tseem tuaj yeem tshwm sim thaum qhov sib txuas dav dhau, ua rau cov hlau yaj uas muaj rau kev sib txuas tsawg dua.

Kev daws teeb meem: Los ntawm kev tswj lub zog thiab qhov ceev ntawm kev vuam kom sib haum xeeb, kev hlawv tawm tuaj yeem tiv thaiv tau, kom ntseeg tau tias lub pas dej vuam tau tswj hwm kom zoo rau kev sib txuas zoo tshaj plaws.

5. Kev txiav qis dua

Ua rau: Thaum lub vuam qeeb dhau, qhov vuam yuav tsis zoo, ua rau muaj qhov vuam loj thiab dav. Qhov ntim ntawm cov hlau uas yaj ntau ntxiv ua rau nws nyuaj rau qhov nro ntawm qhov chaw tuav cov hlau uas ua kua rau hauv qhov chaw, ua rau nws poob qis.

Kev daws teeb meem: Kev txo qis qhov ceev ntawm lub zog tuaj yeem pab tiv thaiv kev txiav qis, ua kom lub pas dej ua kom molten tswj nws cov duab thiab lub zog thoob plaws hauv cov txheej txheem.

Lub Luag Haujlwm ntawm Cov Dej Txias Hauv Laser Welding

Ntxiv rau cov kev daws teeb meem saum toj no, kev tswj hwm qhov kub thiab txias zoo tshaj plaws ntawm lub tshuab vuam laser yog qhov tseem ceeb rau kev tiv thaiv cov teeb meem no. Qhov no yog qhov uas cov dej txias tuaj rau hauv kev ua si. Kev siv lub tshuab txias dej thaum lub sijhawm vuam laser yog qhov tseem ceeb vim tias nws pab tswj qhov kub thiab txias tas li hauv lub laser thiab cov khoom ua haujlwm. Los ntawm kev tswj hwm qhov kub hauv thaj chaw vuam, cov dej txias txo qhov chaw cuam tshuam los ntawm cua sov thiab tiv thaiv cov khoom siv kho qhov muag rhiab heev los ntawm kev puas tsuaj thermal. Qhov no ua kom muaj kev ruaj khov thiab zoo ntawm lub teeb laser, thaum kawg txhim kho qhov zoo ntawm kev vuam thiab txo qhov yuav tshwm sim ntawm qhov tsis zoo xws li tawg thiab porosity. Ntxiv mus, cov dej txias txuas ntxiv lub neej ntawm koj cov khoom siv los ntawm kev tiv thaiv kev kub dhau thiab muab kev ua haujlwm txhim khu kev qha, ruaj khov.

Xaus Lus: Los ntawm kev nkag siab txog cov hauv paus ntawm cov teeb meem laser vuam thiab kev siv cov kev daws teeb meem zoo, xws li preheating, kho lub zog thiab qhov ceev, thiab siv cov chillers, koj tuaj yeem txhim kho qhov zoo ntawm vuam. Cov kev ntsuas no ua kom ntseeg tau tias cov khoom zoo, zoo nkauj, thiab ruaj khov, thaum tseem txhim kho kev ua haujlwm tag nrho thiab lub neej ntawm koj cov khoom siv laser vuam.

Yog xav paub ntxiv txog yuav ua li cas kom koj cov txheej txheem laser vuam zoo dua nrog cov kev daws teeb meem txias siab heev, thov hu rau peb.
