Dab tsi yog qhov yuav tsum tau ua rau cov khoom ntawm cov dej laum me ntsis los ntawm laser vuam?

Dab tsi yog qhov yuav tsum tau ua rau lub pob zeb diamond laum me (steel cev) cov khoom siv hauv Laser Vuam?

 

 

 

Taw qhia:

Raws li lub siab - lub zog - nter vuam txoj kev nruj thiab cov kev cai tshwj xeeb ntawm lub pob zeb diamond laum khoom siv. Tsis yog txhua tus hlau yog haum rau laser vuam hauv kev ua cov khoom ntawm pob zeb diamond laum.

 

 

Ⅰ: Dab tsi tshwj xeeb txog laser - welded pob zeb diamond laum?

Cov yam ntxwv tshwj xeeb ntawm laser - welded pob zeb diamond tho thiab siv cov khoom siv hluav taws xob ntau dua (xws li pob zeb diamond ntu / cov lus qhia thiab cov hlau ua kom zoo).

 

Cov kev zoo no tuaj yeem suav tau hauv peb qhov tseem ceeb:

 

1 Txhim Kho Kev Sib Txuas Kev Sib Raug Zoo:

• Lub zog tsim hluav taws xob yog feeb meej, tsim kom muaj kev sib sib zog nqus -}} penetration weld hlaws. Qhov weld hlau muaj qhov siab dua thiab yog qhov deb dua tiv taus kev tawg thiab ua kom muaj kev cuam tshuam nrog kev cuam tshuam nrog kev kub ntxhov thiab cov dej nrawm} nrawm} nrawm} kev nrawm nrawm nrog tho me me.

 

2 minimized substrate (tho qhov khoom / laum cov khoom) puas tsuaj:

• Laser vuam ua rau muaj tshav kub li cua sov - bead discource (tho kev sib tsoo ntawm cov laum me ntsis (laum steel lub cev / laum cov khoom siv).

 

3 Ntau Lawm Ntau Lawm:

• Laser Vuam ua cov kev pab cuam txiav txuas ntxiv nrog kev sib tsoo siab (3-5 zaug ntxiv rau kev sib tsoo thiab cov nqi ntawm tho kev.

 

: Cov kev xav tau rau Laser Vuam ntawm dej laum me ntsis subtrates

Cov ntsiab lus tseem ceeb rau laser vuam ntawm dej laum me ntsis kev tsom xam ntawm peb qhov ntev: cov khoom sib xyaw, thiab qhov tseeb ntawm vuam zoo thiab ua tau zoo.

1. Cov khoom siv muaj pes tsawg leeg:

• Cov ntaub ntawv hlau nrog muaj zog laser compatibility yuav tsum tau xaiv, feem ntau yog}} Cov ntaub ntawv no muaj cov ntsiab lus carbon qis (feem ntau tsawg dua lossis sib npaug nrog 0.25%), uas tiv thaiv xws li cov kab nrib pleb
• Siab -} carbon thiab siab-}}}}}} ceev steel) raug txwv. Laser vuam ntawm cov khoom tuaj yeem yooj yim tsim cov qauv nyuaj, ua rau substrate embrittlement thiab weld cracking.

 

2. Cov kev xav tau nto nto:

• Tsis muaj roj stains / xeb: Lub ntsej muag portstrate vuam (qhov kawg thiab sab ntsej muag uas hu kom huv si ntawm cov roj sticks, anti {}} Cov xeb roj, thiab oxide nplai. Txwv tsis pub, roj hlawv thiab tsim kom hws, thiab oxide nplai yuav cuam tshuam rau kev sib kis laser laser lub zog, ua rau hauv Welds tsis zoo.
• Yuav tsum tau tswj hwm saum npoo weld chaw yuav tsum tau tswj tsis pub dhau los yog sib npaug rau thaj chaw tsis muaj zog, ua rau muaj qee qhov ua tsis tiav.

 

3. Dag nrho thiab qhov tseeb qhov tseeb qhov raug:

• Cov khaub ncaws tuab zoo nkauj tuab: cov tuab tuab tiv thaiv cov txheej txheem weld kawg yuav tsum muaj tsawg dua lossis sib npaug ± 0.1mm. Kev sib txawv ntau dhau tuaj yeem ua rau txoj haujlwm laser focus kom hloov, cuam tshuam rau Weld nkag mus sib xws.
• Siab kawg ntsej muag Flatsness: lub ntsej muag tsis ncaj ncees ntawm Weld kawg lub ntsej muag yuav tsum yog qhov zoo dua lossis sib npaug weld folding thiab tsis muaj lub zog tsis txaus siab vim muaj lub zog ntau dhau.
• Tsim nyog Coaxial: Qhov tag nrho coaxiality ntawm substrate yuav tsum tsawg dua los yog sib npaug ntawm cov kav dej tsis sib xws thaum lub siab -}}}}}}}} kev sib hloov ceev.

 

 

Ⅲ: Uas tsawg {- Cov hlau hlau feem ntau haum rau Laser Vuam?

Qhov tsim nyog tshaj plaws qis - @} {{{{{1 }nd / E (Lub Tebchaws) thiab S3555Nl (European Txujcab). Lawv txoj kev muaj pes tsawg leeg thiab microstration dav dav yog sib xws nrog tus nqi txias thiab lub zog siab ntom ntawm laser vuam.

 

Cov ntsiab lus tseem ceeb ntawm kev xaiv hom hlau no nyob rau hauv peb qhov tseem ceeb:

1. Tsis tshua muaj kev phom sij qis:

• Cov ntsiab lus carbon cov ntsiab lus yog nruj me ntsis tswj tau qis dua 0.16%, thiab ti (niobium), thiab ti (titanium) Cov ntsiab lus qis ntawm kev ua phem impurities xws li sulphorus (feem ntau tsawg dua lossis sib npaug ntawm 0.035%) txo qhov kev pheej hmoo ntawm intergranular.

 

2. Txhab nrog cov khoom sib koom ua ke:

• Microalloying ntsiab tuaj yeem offset lub coarsening tshwm sim los ntawm kev txias nrawm ntawm Laser vuam thiab dispersion ntxiv lawm. Qhov no ua kom ntseeg tau tias lub zog thiab qis - kub ntau dua los yog sib npaug ntawm cov niam txiv muaj kev sib luag ntawm cov khoom siv.

 

3. Cov txheej txheem muaj zog hloov tau:

• Cov pa roj carbon sib npaug (cev) ntawm cov hlau feem ntau yog tsawg dua lossis sib npaug rau 0.45%. Tsis muaj qhov nyuaj preheating lossis post - cov txheej txheem cua sov yog xav tau thaum vuam (rau nyias {}} gauge seem). Nws tuaj yeem ua tau ncaj qha rau lub siab - nrawm vuam yuav tsum tau siv ntawm Laser vuam. Nyob rau tib lub sijhawm, nws tsis yooj yim los tsim tej yam tsis xws li pores thiab undercuts, txo qhov nyuaj ntawm cov txheej txheem tswj.

 

Ⅳ: Dab tsi yog qhov kev pheej hmoo tseem ceeb ntawm laser vuam Q235 steel, feem ntau yog siv rau dej laum me ntsis hauv Suav teb?

Txoj kev pheej hmoo ntawm Laser vuam Q235 steel yog qhov ntxim nyiam tawg thiab porosity nyob rau hauv lub tshuab hluav taws xob, tshwj xeeb yog tsawg- kub sab). Qhov no yog feem ntau vim yog kev tsis sib xws ntawm nws txoj kev muaj pes tsawg leeg thiab cov txheej txheem cov yam ntxwv ntawm Laser Vuam.

 

Cov kev pheej hmoo tshwj xeeb tuaj yeem faib rau hauv plaub pawg, nrog cov yuam sij cuam tshuam thiab kev rau txim raws li nram no:

1. Metallurgical thiab cov khoom ntiag tug muaj kev phom sij

• Txias tawg pleb: Q235 steel muaj cov pa roj carbon ntau (kwv yees 0.14% -0.2%) thiab cov impurities xws li sulfur thiab phosphorus. Laser Vie cov txiaj ntsig tau ua rau muaj kev txias heev (nrawm dua li arc vuam), uas tuaj yeem coj tau yooj yim martensite hauv weld cheeb tsam. Tsis tas li ntawd, kev tsis txaus siab nce intergranular kev ntxhov siab, thaum kawg kev tawg txias thiab txo qis zog.
• Txo cov tawv tawv: ua kom txias sai sai ntawm cov nplej hauv weld thiab tshav kub}} kub cuam tshuam rau kev tsim ntawm Widmanstäten qauv. Qhov no cuam tshuam qhov tsawg - kub cuam tshuam tawv ntawm kev sib koom tes, ua rau nws raug mob kom tsis tshua muaj kub lossis ntxhov siab.

 

2. Kev pheej hmoo ntawm cov txheej txheem tsis xws luag

• Porosity: thaj tsam Q235 yog qhov ua rau oxidation (ua fe₂o₃). Yog tias xeb thiab cov roj tshem tawm ua ntej vuam, "tob nkag mus vuam tuaj yeem kos cov khoom siv impurities lossis oxide pas dej. Ceev sai cua txias tiv thaiv lawv los ntawm kev khiav ceev ceev, ua rau muaj qhov hws sib khi thiab thauj khoom {{pearing} cov kabmob muaj peev xwm.
• Undercutting thiab tsis tiav kev nkag mus: lub laser hluav taws xob ceev yog feeb meej. Kev sib txuam tsis raug ntawm cov tsis muaj zog (xws li lub zog ceev thiab ntsuas kom yooj yim) lossis ua kom tsis tiav ntawm lub hauv paus (ua tsis tiav cov ntsiab lus kub.

 

3. Kev ua haujlwm thiab kev tiv thaiv kev pheej hmoo

• Laser hluav taws xob: lub siab - Lub Zog Laser Laser Beam (tshwj xeeb tshaj yog nyob rau hauv Laser Vuam tuaj yeem hlawv cov tawv nqaij thiab qhov muag. Cov cuab yeej tshwj xeeb muaj kev tiv thaiv tshwj xeeb, raws li ua tsis tau ua li ntawd yuav ua rau muaj kev puas tsuaj lossis tawv nqaij hlawv.
• Lub ntsej muag thiab cov pa taws: Q235 vuam ua rau cov pa roj xws li Feso thiab MNO. Ntev - kev siv inhalation ntev tuaj yeem ua kom muaj teeb meem pa. Siab - Cov tis muaj peev xwm kuj tseem tuaj yeem tiv thaiv cov khoom nyob ze ze cov khoom siv hluav taws, rau hluav taws kub.

 

4. Kev phom sij ntawm kev siv tom ntej

• Muaj kev txhim kho corrosion: Oxide zaj duab xis nyob rau hauv thaj chaw weld raug rhuav tshem, thiab cov nplej loj thiab sib xyaw ua ke yog qhov tseem ceeb. Yog tias siv nyob rau hauv ib puag ncig noo lossis corrosive, thaj chaw corrosion (xws li pitting) yog yuav tshwm sim, ua kom muaj feem xyuam tivtawm.
