Spot welding yog cov txheej txheem dav siv los koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam.Nws paub txog nws txoj kev ua tau zoo thiab kev ntseeg siab hauv kev tsim kev sib raug zoo ntawm cov hlau.Txawm li cas los xij, thaum lub sijhawm vuam txheej txheem, koj tuaj yeem ntsib qhov teeb meem hu ua spatter.Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj tom qab spatter tsim nyob rau hauv qhov chaw tsis kam vuam thiab yuav ua li cas txo nws.

Dab tsi yog Spatter hauv Spot Welding?
Spatter yog hais txog cov hlau me me uas tuaj yeem raug tshem tawm ntawm qhov chaw vuam thaum lub sijhawm vuam txheej txheem.Cov tee dej no tuaj yeem tawg thiab ua raws li cov khoom ua haujlwm ib puag ncig, cov khoom siv, lossis txawm tias cov welder.Spatter tsis tsuas yog cuam tshuam cov tsos ntawm cov vuam, tab sis kuj tuaj yeem ua rau muaj kev txhawj xeeb txog kev nyab xeeb thiab kev nyab xeeb hauv kev siv vuam.
Ua rau Spatter hauv Resistance Spot Welding:
- Contaminated Electrodes:Ib qho laj thawj ntawm spatter yog kab mob welding electrodes.Cov impurities lossis cov khoom txawv teb chaws ntawm qhov chaw electrode tuaj yeem ua rau cov cua sov tsis sib xws thiab, yog li, kev sib tsoo.Kev tu thiab tswj cov electrodes tsis tu ncua tuaj yeem pab txo qhov teeb meem no.
- Siab tsis sib haum:Kev tuav lub siab zoo ib yam ntawm cov khoom ua haujlwm thaum lub sijhawm vuam yog qhov tseem ceeb.Kev tsis txaus siab tuaj yeem ua rau muaj qhov tsis zoo arcing, uas ua rau tawg.Kev ntsuas kom raug thiab kev saib xyuas ntawm lub tshuab vuam tuaj yeem pab ua kom lub siab sib xws.
- Inaccurate Vuam Parameters:Kev teeb tsa tsis raug rau vuam tam sim no, lub sijhawm, lossis lub zog electrode tuaj yeem ua rau tawg.Nws yog ib qho tseem ceeb kom ua raws li cov chaw tsim khoom cov lus qhia thiab kho qhov tsis raws li cov khoom thickness thiab hom raug welded.
- Cov khoom paug:Kev muaj cov kab mob xws li xeb, roj, lossis pleev xim rau ntawm cov hlau uas yuav tsum tau welded tuaj yeem ua rau tawg.Kev npaj cov khoom ua haujlwm los ntawm kev ntxuav thiab degreasing lawv ua ntej vuam tuaj yeem tiv thaiv qhov teeb meem no.
- Tsis zoo Workpiece Fit-Up:Yog hais tias lub workpieces tsis zoo sib xws thiab nruj nreem clamped ua ke, qhov hluav taws xob tsis kam ntawm vuam taw tes yuav txawv, ua rau tsis sib xws cua sov thiab spatter.Xyuas kom meej tias cov workpieces ruaj ntseg ua ntej vuam.
Mitigating Spatter hauv Resistance Spot Welding:
- Electrode Maintenance:Khaws cov electrodes kom huv si thiab tsis muaj impurities.Tsis tu ncua tshuaj xyuas thiab ntxuav lawv kom ntseeg tau tias kev ua haujlwm zoo.
- Kev Siab Siab:Saib xyuas thiab tswj kom muaj zog electrode zoo ib yam thoob plaws hauv cov txheej txheem vuam kom paub meej txawm tias cua sov thiab txo qhov tawg.
- Yog Parameters:Teem lub vuam tsis raws li cov khoom specifications thiab cov chaw tsim tshuaj paus cov lus pom zoo.
- Kev npaj nto:Ua tib zoo ntxuav thiab degrease cov hlau qhov chaw yuav tsum tau welded kom tsis txhob muaj kab mob.
- Kev kho kom zoo:Xyuas kom meej tias cov workpieces raug ua kom raug thiab ruaj ntseg clamped kom muaj kev sib haum xeeb thaum lub sij hawm vuam.
Nyob rau hauv xaus, spatter tsim nyob rau hauv qhov chaw welding muaj peev xwm raug ntaus nqi rau ntau yam, xws li electrode paug, inconsistent siab, welding tsis raug, cov khoom paug, thiab tsis zoo workpiece haum.Los ntawm kev daws cov teeb meem no thiab ua raws li kev saib xyuas thiab kev siv vuam kom zoo, nws muaj peev xwm txo tau qhov tawg thiab ua tiav qhov zoo ntawm qhov chaw welds.
