Kev siv vuam tsis xws luag thiab cov kev daws teeb meem?

What are the core advantages of the laser welding machine?

Nov yog cov kev siv vuam tsis xws luag nyob rau hauv laser vuam, thiab tsom cov kev daws teeb meem, muab cov lus pom zoo tshwj xeeb raws li cov khoom siv thiab cov txheej txheem tsis sib xws:

1. Weld discoloration / Oxidation

Tshwm sim: Weld nto qhia qhia cov txheej oxide dub, txo cov khoom siv mechanical .
Cov laj thawj:

Tsis txaus pab roj lossis cua hlob (e {{{{} g}! Argon ntws <8l / min).

Uncleaned roj / grease lossis oxide txheej ntawm cov khoom saum npoo (e {{} g}}}}} oxide zaj duab xis).

Ntau dhau qeeb rauv vuam ceev ua rau cov oxidation kub .

Cov kev daws teeb meem:

Roj ua kom zoo: Kho cov av mus rau 15-20l / min rau cov roj stainless hlau nozzle (3-5mm aperture) los xyuas kom cov pa npog roj molten {}}

Nto Pretreatment: So cov ntaub ntawv tooj liab nrog acetone ua ntej vuam; mechanically grind los yog tshuaj tshem tawm xeb los ntawm txhuas alloys (e {{} g}}}} {.

Parameter kev hloov kho: Nce vuam ceev los 10% -20% lossis txo lub zog los ntawm 5% -10% kom txo cov tswv yim tshav kub {}}

2. hlawv-los (molten pas collapse)

Tshwm sim: Cov khoom nkag mus rau tshwm sim, tsim qhov qhov nyob hauv weld .
Cov laj thawj:

Ntau dhau high laser fais fab (e {. g}}}}}}} {.

Qeeb dhau vuam ceev lossis dhau me me defocus .

Miscatch ntawm cov khoom tuab thiab cov tsis muaj (e {{{} g}}}}}}}} 5 hli nyias daim hlau).

Kev Tswj Fais Fab: Txheeb xyuas lub zog rau cov khoom tuab (e {.}}}}}}}, 400-6 txhuas phaj); Txo lub zog hluav taws xob hauv theem (e {{{5} g}}}}}}}, xaus ntawm 80%) {9}.

Ceev & Defocus: Ua kom nce Vuam ceev ntawm 1m / min rau 1 .}} 5m / min; Kho focal txoj hauj lwm los ntawm 0 hli rau +0.5 mm (zoo defocus).

Mem tes hom: Hloov mus rau qhov siab pulses (saum toj no 200z) kom luv-mem tes zog ua lub sijhawm {}}

3.}} txias weld (tsis tiav fusion)

Tshwm sim: Tus weld tshwm sim sab nraud tab sis tsis muaj metallurgical bonding sab hauv, nquag mus rau fracture thaum sim ntsuas kub tensile {}}
Cov laj thawj:

Tsis txaus siv laser lub zog (lub zog <200w lossis ntau dhau lawm) .

Focal Taw Dimiation (DeCus yuam kev> ± 0 . 3mm).

Cov hlau pub hlau pub dawb (e {{{0} g}}}}}}}}}} {.

Cov kev daws teeb meem:

ZOG PERCRE: Ntsuas cov zis laser laser nrog lub zog hluav taws xob (yuam kev yuav tsum yog <± 5%); xyuas kom meej lub zog nce mus txog tsawg kawg yog 300W rau nyias phaj vuam (1 hli stainless hlau).

Focal point-duning: Calibrate lub focal point siv tus ntoo khaub lig-plaub hau kev sib txawv; Siv laser taug kev system (raug ± 0 {. 1mm) rau precision vuam.

Hlau Pub Kev Ua Haujlwm Zoo: Kos Hlau Pub Cov Menyuam Khoom Noj (0}}}}}}}

{{0 {}} nrib pleb (kub / txias tawg)

Tshwm sim: Linear tawg tshwm nyob rau hauv weld lossis kub-cuam tshuam cheeb tsam .
Cov laj thawj:

Cov khoom siv kev ntxhov siab (e {{{{{} g {{1} {.

Ntau dhau txias txias tus nqi (e {. g}!, Txhuas}, txhuas alloy tsis muaj preheating).

Cov Pulse Pulse Paus zaus ua rau tsis pom kev thycling .

Cov kev daws teeb meem:

Kev Kho Mob Preheating: Preheat high-zog hlau rau 150-200℃thiab txhuas alloy rau 120℃siv lub cua sov infrared cua sov {}}

Txheej txheem optimization: Txo cov mem tes pulse zaus rau 20-50hz; Txais yuav "lub zog ramp-up / ramp-down" hom (e {}} → 100% → 100%.

Hlau Sib Tw: Siv Ni-based hlau (e {{1} g {}}}}}) Rau cam khwb cia hlau vuam kom txo ward hardness txawv; Thov ntau txheej multi-dhau vuam rau cov paib tuab mus rau disperse kev ntxhov siab.

{{05. porosity (bubbles sab hauv)

Tshwm sim: Puag ncig lossis elliptical voids muaj nyob rau hauv weld .
Cov laj thawj:

Noo noo nyob rau hauv cov roj tiv thaiv (dew point> {{{}} degree) .

Cov roj av nkev ntawm cov khoom saum npoo (e {. g}}}}} .

Molten pas hlau boiling (tshwm sim los ntawm ntau lub zog ua rau vaporization) .

Cov kev daws teeb meem:

Gas Kom Qhuav: Siv cov molecular sieve tshuab ziab khaub ncaws (lwg

Nto Kho: Cov ntaub yas yas ua ntej vuam (80℃× 2h); Tshem cov txheej ntawm cov hlau (e {{2} g ., zom galvanized txheej) {}}

Kev Kho Kom Haum Fais Fab: Txo lub zog los ntawm 10% -15% lossis txais yuav mem tes + Low-satecency "hom (E} zaus 10hz, ceev} 8m / min).

{{06. undercut (Groove ntawm Weld Ntug)

Tshwm sim: Ib qho zawj uas muaj zawj nyob ntawm kev sib tshuam ntawm weld thiab puag hlau .
Cov laj thawj:

Uneven laser lub zog faib (chaw Ellipticity> 1 . 2).

Ntau dhau nrawm vuam ceev ua rau cov pas dej tsis txaus molten .

Kev tiv thaiv tau ntau dhau ntawm cov roj ua kom muaj roj yuam kom tawg cov hlau .

Cov kev daws teeb meem:

Kev saib xyuas calibration: Ntes qhov kev sib tw nrog cov nqaj mosalalzer thiab kho lub collimator mus rau mellomticity <1.05.

Kev Ceev & Lub: Txo vuam ceev los ntawm 2m / min rau 1 {4 4}}}}}}} 5m / min thiab tswj teeb lub teeb at at at at 15 degree-nyoog degree.

Tswj Roj: Hloov mus rau sab roj tshuab (45℃kaum sab xis) thiab txo cov ntws los ntawm 20l / min mus rau 15l / min.

7.} Tsis muaj qhov nqus tsis tau (tsis muaj weld tob)

Tshwm sim: Weld nkag yog tsawg dua 80% ntawm cov khoom tuab .
Cov laj thawj:

Tsis muaj lub zog (e {{{{0} g .}}}, 1000W rau 3mm steel phaj) {4} {4}

Ntau dhau defocus loj (tsis zoo defocus <-1 mm) .

Cov khoom siv siab reflyity (e . g . {.

Cov kev daws teeb meem:

Ua kom muaj zog ntxiv: Pom zoo 2000-2500W-2500W rau 3 hli Stainless Hlau; hloov mus rau xiav laser rau tooj liab vuam (nqus tau nce ntxiv rau 60%) .

Defocus kev kho kho: MUAB ceev txawm defocus (-1.5 mm) rau tob nkag vuam "(amplitude vuam" (amplitude vuam "(}} 5 hli) kom nce Weld dav.

Nto Kho: Pre-phaj tooj liab nrog npib tsib xee (2-3μm thickness) lossis sandblast ntawm cov npoo los txhim kho laser .

Kho cov kev daws teeb meem cov txheej txheem kev pom zoo

Kuaj cov khoom siv ua ntej tsis muaj: Tshawb xyuas cov txheej txheem kho qhov muag, roj txaus, thiab hlau pub mis rau kev txawv txav .

Ib Leeg-Qhov Ntsuas Ib Leeg: Kho tsuas yog ib qho parameter (e {. g., sau cov nyhuv, ces ua kom zoo.

Khoom Siv Khoom Siv Tsiav Cov Lus: Establish a database of parameters for common materials (e.g., 0.3mm stainless steel → 300W power, 1.8m/min speed, 12L/min argon).

Los ntawm kev tsom cov txheej txheem tsis sib haum thiab cov cuab yeej siv cov xwm txheej, laser vuam tawm yuav tsum tau them rau kev kho mob siab tshaj plaws (tooj liab) thiab aluminium) vuam .
