Vuam spatter nyob rau hauv qhov chaw welding tshwm sim thaum molten hlau raug ntiab tawm ntawm lub vuam interface ua ntej nws yuav solidify nyob rau hauv electrode quab yuam. Feem ntau ua rau muaj cua sov ntau dhau, tsis txaus lossis tsis ruaj khov electrode quab yuam, lub sijhawm nyem tsis txaus, cov ntawv tsis zoo - nce, qhov tsis zoo ntawm qhov chaw thiab hnav lossis tsis zoo electrodes.
Nyob rau hauv qhov chaw vuam, qhov kev tshwm sim no yog hu ua weld expulsion. Nws txawv ntawm MIG lossis MAG spatter, uas yog txuam nrog hluav taws xob arc, muab tub lim- xaim xaim thiab tiv thaiv roj. Tsab xov xwm no tsuas yog tsom rau kev tshem tawm thaum lub sij hawm MFDC thiab cov pa ua haujlwm qhov chaw vuam.
Txo kev tshem tawm tsis yog txhais tau tias txo qis cov vuam tam sim no. Lub tshuab teeb tsa, qhov tseeb tam sim no, lub sijhawm vuam, lub zog hluav taws xob thiab cov khoom siv yuav tsum raug kuaj ua ke, ua raws li lwm qhov kev ntsuas lub zog -.
Qhov tseem ceeb ntawm Spatter hauv Resistance Spot Welding
| Ua tau | Yuav ua li cas | Yuav kuaj ua ntej |
|---|---|---|
| Tshaj welding tam sim no | Thaum tshav kub kub tsim sai dua qhov chaw weld tuaj yeem muaj cov hlau molten | Tshawb xyuas qhov khoom xa tuaj tam sim no thiab sib piv nrog lub sijhawm pom zoo |
| Weld lub sij hawm ntev heev | Lub nugget tseem loj hlob mus txog thaum cov hlau molten raug tshem tawm | Paub meej weld lub sij hawm thiab cov tswj lub sij hawm units |
| Tsis txaus electrode quab yuam | Cov nplooj ntawv tsis tuav ruaj txaus kom muaj cov molten nugget | Txheeb xyuas qhov tseeb electrode quab yuam, tsis yog cua siab xwb |
| Lub sijhawm nyem tsis txaus | Tam sim no pib ua ntej kev sib cuag electrode tag nrho | Tshawb xyuas lub zog tsim thiab tam sim no - pib lub sijhawm |

Cov tswv yim los txo Vuam Spatter
- Rational Parameter Chaw: Tsis txaus lossis tsis ruaj khov electrode quab yuam tuaj yeem txo cov molten- hlau ntim thiab tsim kev sib cuag tsis sib xws ntawm cov ntawv. Kev quab yuam ntau dhau tuaj yeem txo qhov kev tiv thaiv tiv thaiv thiab hloov kev tsim nugget. Lub zog raug yuav tsum tau tsim ua ke nrog lub sijhawm tam sim no thiab vuam.
- Cov cuab yeej tu tsis tu ncua: Lub sijhawm tshuaj xyuas thiab tswj xyuas qhov nruab nrab zaus qhov chaw welder kom ntseeg tau tias nws nyob hauv qhov zoo. Hloov cov electrodes uas hnav hnyav sai sai.
- Xaiv cov khoom siv vuam tsim nyog: Siv cov khoom siv vuam tsim nyog thiab zam cov impurities lossis oxide txheej.
- Optimize Welding Sequence thiab Methods: Kho cov vuam sib txuas thiab cov txheej txheem ua haujlwm kom ntseeg tau tias cov cua sov xa tawm thaum lub sij hawm vuam thiab txo qhov kev sib tsoo.
Yuav ua li cas txo Spot Weld Spatter?
1. Tshawb xyuas lub workpiece ua ntej hloov cov kev ntsuas
Paub meej tias cov ntawv txheeb tau raug muab tso rau, qhov sib koom ua ke tsis muaj qhov sib txawv ntawm qhov sib txawv thiab qhov chaw vuam yog qhov sib xws. Kev hloov pauv tsis tuaj yeem them rov qab rau qhov tsis ruaj khov -up.
2. Tshawb xyuas thiab teeb tsa cov electrodes
Tshawb xyuas lub ntsej muag electrode rau hnav, pitting, khaws cov khoom thiab tsis raug kev sib raug zoo. Lub ntsej muag electrode hloov pauv ob qho tib si kev sib cuag thiab qhov ceev tam sim no.
3. Txheeb xyuas Electrode Force thiab Squeeze Time
Xyuas kom tseeb tias qhov programmed tam sim no pib tsuas yog tom qab lub zog electrode ruaj khov tau tsim. Yog tias lub tshuab siv pneumatic siab teeb tsa, paub meej tias qhov kev teeb tsa cuam tshuam li cas rau lub zog electrode.
4. Tshawb xyuas lub sijhawm tam sim no thiab Weld
Sib piv cov khoom xa tuaj tam sim no thiab lub sijhawm vuam nrog lub sijhawm pom zoo vuam. Yog tias kev tshem tawm tau pib tom qab kev saib xyuas, kev hloov hluav taws xob lossis cov khoom siv hloov pauv, tshawb xyuas qhov kev hloov pauv ua ntej tsim lub sijhawm tshiab.
5. Kho ib qho kev sib txawv ntawm ib lub sij hawm
Txo qhov tam sim no tuaj yeem tso tseg tsis pom kev tawg tab sis tuaj yeem tsim qhov tsis zoo weld nugget. Ua ib qho kev hloov kho, tsim cov qauv neeg sawv cev thiab rov ua dua qhov xav tau vuam- kev ntsuas zoo.
6. Kev sim ntawm tus nqi ntau lawm
Ob peb cov welds cais tawm yuav tshwm sim tau vim tias cov electrodes muaj sijhawm txias. Khiav qhov kev sim ntawm lub voj voog uas xav tau los txheeb xyuas qhov txias, electrode- hnav lossis quab yuam- teeb meem kev ruaj ntseg.
Yuav ua li cas kom paub tseeb qhov Weld tom qab txo cov spatter?
Kev txo qis hauv qhov pom kev tawg yuav tsum tau ua raws li weld-kev pov thawj zoo. Txwv tsis pub, qhov qis dua - qhov chaw tam sim no yuav zais qhov teeb meem tshem tawm thaum tsim cov khoom tsis zoo lossis tsis muaj zog.
Raws li qhov yuav tsum tau ua ntawm cov khoom lag luam, kev tshuaj xyuas yuav suav nrog kev tshuaj xyuas qhov muag, tev lossis chisel kuaj, tensile-kev ntsuas shear, hla -section xeem lossis lwm txoj kev pom zoo. Txheej txheem- saib xyuas cov ntaub ntawv tuaj yeem pab txheeb xyuas qhov kev hloov pauv, tab sis nws tsis tuaj yeem hloov qhov kev ntsuas lub cev.
FAQ
Q: Dab tsi ua rau vuam spatter hauv qhov chaw vuam?
A: Cov laj thawj tseem ceeb yog lub sijhawm tam sim no lossis lub sijhawm vuam ntau dhau, lub zog hluav taws xob tsis txaus, lub sijhawm nyem tsis txaus, haum tsis zoo - nce, qhov tsis zoo ntawm qhov chaw thiab hnav lossis tsis zoo electrodes.
Q: Dab tsi yog kev tshem tawm hauv qhov chaw vuam?
A: Kev tshem tawm tshwm sim thaum cov hlau molten raug tshem tawm ntawm qhov sib txuas ntawm vuam thaum lub voj voog vuam. Nws yog feem ntau piav raws li qhov chaw vuam spatter, tab sis nws txawv ntawm spatter tsim los ntawm arc- txheej txheem vuam.
Q: Puas yog vuam tam sim no ntau dhau ua rau tawg?
A: Yog lawm, ntau dhau tam sim no tuaj yeem ua rau kev loj hlob sai thiab tshem tawm. Txawm li cas los xij, tam sim no yuav tsum tsis txhob txo kom txog thaum electrode quab yuam, nyem lub sij hawm, haum- nce thiab qhov chaw saum npoo kuj tau kuaj xyuas.
Q: Puas muaj zog electrode tsawg ua rau weld exulsion?
A: Yog. Tsis txaus los yog tsis ruaj khov quab yuam yuav tsis muaj cov hlau molten ntawm cov nplooj ntawv. Lub zog hluav taws xob tiag tiag yuav tsum raug txheeb xyuas ntau dua li tsuas yog tso siab rau ntawm pneumatic - qhov chaw siab.
Q: Vim li cas spatter tshwm tsuas yog tom qab txuas txuas ntxiv?
A: Lub ntsej muag electrode tuaj yeem ua kom sov, hnav lossis khaws cov khoom thaum tsim khoom. Kev ua haujlwm txias txias, quab yuam kev ruaj ntseg thiab kev hloov pauv ntawm qhov chaw tiv tauj yuav tsum tau kuaj xyuas.
Q: Puas yog MFDC tshem tawm vuam spatter?
A: Tsis yog. MFDC muab cov programmable tam sim no thiab lub sijhawm tswj, tab sis kev tshem tawm tseem tuaj yeem tshwm sim yog tias lub sijhawm vuam, electrode quab yuam, haum -nce, txias lossis electrode yam tsis zoo.
Cov ntsiab lus: Txo cov kab nrib pleb yam tsis muaj qhov Weld tsis muaj zog
Dab tsi ua rau vuam spatter hauv anruab nrab- zaus welder? Nyob rau hauv qhov chaw welding, spatter-ntau yog hu ua weld expulsion- feem ntau yog tshwm sim los ntawm lub sij hawm tam sim no los yog weld ntau dhau, lub zog electrode tsis txaus, lub sij hawm tsis txaus, cov ntawv tsis zoo - nce, qhov tsis zoo ntawm qhov chaw, los yog hnav thiab tsis zoo electrodes.
Pib los ntawm kev txheeb xyuas qhov chaw ua haujlwm thiab cov khoom siv hluav taws xob, tom qab ntawd txheeb xyuas cov electrode quab yuam, nyem lub sijhawm, xa tam sim no, lub sijhawm vuam thiab txias. Hloov ib qho sib txawv ntawm ib lub sij hawm thiab sim cov vuam dua. Txo qhov pom spatter tsuas yog ua tiav thaum lub vuam nugget thiab lub zog sib koom ua ke tseem ua tau raws li qhov yuav tsum tau ua.
