Laser vuam yog lub siab ua haujlwm thiab meej vuam txoj kev uas siv lub siab-lub zog-ntom nthe teeb. Niaj hnub no, Laser Vuam tau siv dav hauv ntau yam kev lag luam, xws li: cov khoom lag luam hauv, chaw tsim khoom, iberospace thiab lwm yam kev lag luam lag luam. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm laser vuam, qee yam tsis xws luag lossis cov khoom tsis xws luag yuav tsis tau tshwm sim. Tsuas yog los ntawm kev nkag siab ntawm cov pitfalls thiab kev kawm paub yuav ua li cas zam lawv tuaj yeem muaj txiaj ntsig ntawm laser vuam yuav zoo dua siv. Hnub no, Hangao Tech (Seko Machinery) Coj koj kom muaj cov teeb meem tseem ceeb thaum laser vuam. Peb pab neeg puas muaj ntau xyoo hauv tsis siv neeg cov yeeb nkab yob thiab kev ua lub tshuab. Yog tias muaj kev xav tau lossis tsis ntseeg txog Muaj Laser Laser Vuam Raj Zeb Kab Cable Tshuab , txais tos hu rau peb.
10 Feem Laser Weld tsis xws, lawv cov laj thawj thiab cov kev daws teeb meem yog raws li hauv qab no:
1. Weld ci
Lub ntsej muag ua los ntawm Laser vuam sib cuam tshuam rau qhov zoo ntawm Weld Seam, uas tuaj yeem paug thiab ua kom cov lens puas tsuaj. Cov kev ua tau zoo tshaj plaws yog: Tom qab Laser Vuam yog ua tiav, ntau cov hlau ua kom pom nyob rau saum npoo ntawm cov khoom lossis cov haujlwm ua haujlwm, thiab ua haujlwm rau ntawm cov khoom lossis ua haujlwm.
Cov ua rau txaws:
Cov khoom siv txheej txheem lossis cov npoo ntawm qhov chaw ua haujlwm tsis huv lossis cov roj ntsha lossis cov pa paug, lossis nws yuav tshwm sim los ntawm kev hloov pauv ntawm cov khoom nws tus kheej.
Kev daws:
A. Ua tib zoo saib xyuas cov ntaub ntawv ntxuav lossis cov haujlwm ua ntej laser vuam.
B. Txaws yog ncaj qha rau cov hwj huam ceev. Tsim nyog txo welding lub zog tuaj yeem tiv thaiv tau.
2. Khab
Cov kab nrib pleb uas tsim los ntawm kev nruam laser vuam feem ntau yog thermal nrib pleb, xws li crystal tawg thiab liquefaction cracks.
Vim li cas rau cov kab nrib pleb:
Feem ntau vim yog ntau dhau shrinkage ua ntej weld tsis yog solidified.
Kev daws:
Kev ntsuas xws li xaim filling thiab preheating tuaj yeem txo lossis tshem tawm cov kab nrib pleb.
3. Stoma
Pores nyob rau saum npoo Weld Seam yog qhov yooj yim tsis xws luag nyob rau hauv laser vuam.
Ua rau porosity:
A. Cov pas dej ua ke ntawm Laser Vuam yog sib sib zog nqus thiab nqaim, thiab cua txias nrawm nrawm nrawm nrawm nrawm nrawm nrawm nrawm. Cov roj tsim tawm hauv cov kua molten pas tsis muaj sij hawm rau txeej, uas yooj yim ua rau kev tsim lub pores.
B. Qhov saum npoo ntawm Weld Seam tsis tau huv, lossis zinc vapor ntawm cov ntawv galvanized evaporates.
Kev daws:
Ntxuav cov npoo ntawm workpiece thiab cov nplaim dej ntawm weld ua ntej vuam los txhim kho qhov loj ntawm zinc thaum rhuab. Ib qho ntxiv, cov kev taw qhia tshuab yuav cuam tshuam rau cov neeg ntawm huab cua.
4. Undercut
Undercut yog hais txog: Lub Vuam Seam tsis zoo sib txuas nrog lub hauv paus, thiab tag nrho cov kev xav tau ntawm Weld ntev, lossis ntau dua qhov yuav tsum tau ntev los ntawm kev lees txais tus qauv.
Tsis muaj laj thawj:
A. Lub vuam ceev nrawm heev, thiab cov kua hlau hauv Weld yuav tsis raug tswj nyob rau sab nraum qab ntawm lub me me, sib sau undercuts ntawm ob sab ntawm Weld.
B. Yog tias cov rooj sib txoos sib txuas ntawm kev sib koom ua ke loj heev, cov hlau molten rau hauv kev sib koom ua ke yog txo qis, thiab undercutting kuj tseem muaj tshwm sim.
C. Thaum kawg ntawm Laser Vuam, yog tias lub zog poob sijhawm dhau lawm, lub qhov me me rau kev poob dej, uas yuav ua rau muaj kab ke hauv zos.
Kev daws:
A. Kev tswj cov khoom siv ua haujlwm thiab nrawm nrawm ntawm cov laser vuam tshuab kom tsis txhob undercutting.
B. Lub undercut ntawm Weld pom hauv kev soj ntsuam tuaj yeem ua polished, ntxuav thiab kho kom haum rau qhov yuav tsum tau ua ntawm cov qauv txais.
5. Weld tsub zuj zuj
Weld leeg yog qhov tseemciously overfilled, thiab Weld Seam yog siab dhau thaum sau.
Cov ua rau ntawm Weld tsub zuj zuj:
Hlau pub ceev ceev yog kev nrawm heev lossis vuam ceev yog qeeb heev thaum vuam.
Kev daws:
Ua kom cov vuam ceev lossis txo cov kav hlau pub ceev, lossis txo cov hwj roj laser.
6. Vuav sib cav
Weld hlau yuav tsis ua rau lub hauv paus ntawm cov qauv sib luag.
Vim li cas rau cov xwm txheej no:
Qhov muab tso tawm tsis raug thaum lub sij hawm vuam, lossis tsis muaj tseeb puv vuam lub sij hawm thiab vuam hlau polosignment.
Kev daws:
Kho cov vuam txoj hauj lwm, lossis kho cov vuam lub sijhawm kho thiab txoj hauj lwm ntawm vuam hlau, nrog rau txoj haujlwm ntawm lub teeb hlau thiab vuam hlau thiab vuam sib dhos.
7. Weld Kev Nyuaj Siab
Weld tog yog hais txog qhov tshwm sim uas tus weld hlau nto yog kev nyuaj siab.
Cov ua rau Weld tog:
Thaum brazing, lub chaw nruab nrab ntawm cov sib koom sib dhos yog qhov tsis zoo. Lub chaw nruab nrab ntawm lub teeb pom kev ze rau cov phaj qis thiab deviates los ntawm nruab nrab ntawm Weld Seam, ua rau ib feem ntawm lub hauv paus hlau rau yaj.
Kev daws:
Kho lub teeb filament txuam.
8. Tsis tsim nyog weld tsim
Kev ua tsis zoo weld suav nrog: weld weld ripples, tsis sib xws Welds, kev hloov pauv tsis sib xws ntawm Welds, Welsals, thiab Welds tsis ncaj ncees.
Qhov laj thawj rau qhov xwm txheej no:
Thaum lub npoo weld yog brazed, cov hlau pub dawb tsis ruaj khov, lossis lub teeb tsis txuas ntxiv.
Kev daws:
Kho qhov ruaj khov ntawm lub cuab yeej.
9. Vuam
Weld Bead yog: Thaum Weld Trailector Hloov Siab, Weld Bead lossis Txoj Cai Tsis Txaus Ntseeg yog nquag tshwm sim ntawm kaum tsev.
Ua:
Txoj kab sib hloov pauv zoo heev, thiab cov lus qhia tsis xwm yeem.
Kev daws:
Weld nyob rau hauv cov tsis zoo tshaj plaws, kho lub kaum sab xis ntawm kev xav kom ua rau cov fab txheej.
10. Nto SLAG INTRUSION
Cov txheej txheem sab nraud ntxiv xa mus rau: thaum lub sij hawm vuam, cov tawv nqaij sluag suav uas tuaj yeem pom los ntawm sab nraud feem ntau tshwm sim ntawm txheej.
Kev tsom xam ntawm kev sib cais ntawm qhov chaw qis qis:
A. Lub sij hawm multi-alultat ntau-dhau vuam, cov txheej txheem interlayer tsis huv; Los yog saum npoo ntawm txheej yav dhau los ntawm weld tsis du lossis saum npoo ntawm weldment tsis ua raws li cov cai.
B. Kev siv kab mob tsis raug cai xws li vuam tsis tshua muaj hluav taws xob lub zog thiab nrawm nrawm vuam.
Kev daws:
A. Xaiv cov vuam kev vuam tam sim no thiab vuam ceev. Cov txheej interlayer yuav tsum tau ntxuav thaum muaj ntau txheej txheem vuam.
B. Sib tsoo kom tshem tawm Weld Seam nrog Slag Compusion ntawm lub npoo, kho vuam yog tsim nyog.
