Yog vim li cas thiab kev daws teeb meem rau blackening ntawm laser vuam tshuab welds

Qhov laj thawj tseem ceeb vim li cas qhov vuam ntawm lub tshuab laser vuam yog xim dub heev feem ntau yog vim qhov tsis raug ntawm cov cua ntws tsis raug lossis tsis txaus txaus ntawm cov roj thaiv, uas ua rau cov khoom oxidize nyob rau hauv kev sib cuag nrog huab cua thaum lub sij hawm vuam thiab cov ntaub ntawv dub oxide. cov

Txhawm rau daws qhov teeb meem ntawm cov welds dub hauv laser vuam tshuab, cov kev ntsuas hauv qab no tuaj yeem ua:

1. Kho qhov ntws thiab kev taw qhia ntawm cov roj thaiv kev tiv thaiv: xyuas kom meej tias qhov ntws ntawm cov roj tiv thaiv tau txaus los npog tag nrho cov vuam cheeb tsam thiab tiv thaiv cov pa oxygen hauv huab cua los ntawm kev nkag mus rau hauv qhov vuam. Cov kev taw qhia airflow ntawm cov roj shielding yuav tsum yog qhov sib txawv ntawm qhov kev taw qhia ntawm lub workpiece kom ntseeg tau tias muaj kev sib cais ntawm huab cua.

2. Ua kom zoo rau kev kho qhov chaw ntawm cov khoom siv: Ua ntej vuam, siv cov kuab tshuaj xws li cawv thiab acetone kom huv si ntawm cov khoom kom tshem tawm cov roj thiab oxide zaj duab xis. Rau cov ntaub ntawv uas yooj yim oxidized, pickling los yog alkali ntxuav yuav siv tau rau pretreatment kom txo tau deg oxides.

3. Kho lub laser tsis: Teem lub laser fais fab tsim nyog kom tsis txhob muaj cua sov ntau dhau. Tsim nyog ua kom qhov vuam ceev, txo cov cua sov nkag, thiab tiv thaiv cov khoom los ntawm overheating. Siv pulsed laser welding kom ua tiav cov khoom siv hluav taws xob ntau dua los ntawm kev kho cov mem tes dav thiab zaus.

4. Txhim kho qhov chaw vuam: Ntxuav qhov chaw ua haujlwm tsis tu ncua kom tsis txhob muaj plua plav thiab ya raws nkag mus rau hauv qhov chaw vuam. Thaum muaj kev tso cai, siv cov cuab yeej siv kaw kaw kom cais cov impurities sab nraud.

Cov txheej txheem saum toj no tuaj yeem txo qhov teeb meem ntawm blackening ntawm vuam seams thiab txhim kho vuam zoo thiab efficiency.
