Flash taub qab vuam yog cov txheej txheem tseem ceeb hauv ntau yam kev lag luam, xws li tsheb, kev tsim kho, thiab kev tsim khoom. Cov kev tsis zoo sab nraud hauv cov txheej txheem vuam tuaj yeem cuam tshuam rau qhov zoo thiab kev ncaj ncees ntawm cov welds. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog ntau yam kev tsis zoo sab nraud morphologies ntsib hauv flash taub qab vuam thiab lawv qhov cuam tshuam.
- Surface Contamination: Cov kab mob ntog yog ib qho ntawm cov teeb meem sab nraud feem ntau hauv lub pob tw vuam. Nws tuaj yeem tshwm sim los ntawm qhov muaj xeb, roj, roj, lossis lwm yam khoom txawv teb chaws ntawm qhov chaw ntawm lub workpieces. Thaum cov kab mob no tsis raug tshem tawm kom zoo ua ntej txheej txheem vuam, lawv tuaj yeem ua rau tsis zoo fusion thiab tsis muaj zog welds. Tsis tas li ntawd, kev sib kis ntawm qhov chaw kuj tuaj yeem ua rau tsis muaj cua sov tsis sib xws, cuam tshuam rau tag nrho qhov zoo ntawm qhov sib koom ua ke.
- Misalignment: Misalignment ntawm workpieces yog lwm qhov teeb meem uas tuaj yeem ua rau sab nraud tsis xws luag. Thaum cov khoom ua haujlwm tsis zoo sib xws, nws tuaj yeem ua rau cov cua sov tsis sib xws thiab kev faib tawm siab thaum lub sijhawm vuam. Qhov no tuaj yeem ua rau muaj qhov tsis xws li weld flash, ntau deformation, thiab txawm tias weld tawg. Kev kho kom zoo thiab kev sib raug zoo yog qhov tseem ceeb kom tsis txhob muaj cov teeb meem no.
- Tsis txaus siab: Tsis txaus siab thaum lub sij hawm flash taub qab vuam txheej txheem yuav ua rau tsis zoo welds. Thaum lub siab tsis siv tib yam, nws tuaj yeem ua rau muaj qhov tsis xws luag xws li undercuts thiab tsis muaj fusion. Lub siab txaus yog qhov tseem ceeb los xyuas kom muaj kev sib raug zoo ntawm metallurgical ntawm cov khoom ua haujlwm.
- Electrode Contamination: Cov kab mob sib kis los yog hnav cov electrodes tuaj yeem ua rau muaj qhov tsis xws luag. Cov hluav taws xob uas tsis zoo tuaj yeem ua rau muaj kev hloov pauv hauv kev faib hluav taws xob, uas tuaj yeem ua rau muaj qhov tsis xws li craters thiab hlawv ntau dhau. Kev saib xyuas tsis tu ncua thiab hloov cov electrodes yog tsim nyog los tswj cov vuam zoo.
- Inconsistent Flash: Nyob rau hauv lub pob tw vuam, lub sijhawm thiab kev siv ntawm lub flash yog qhov tseem ceeb uas tuaj yeem cuam tshuam rau qhov vuam zoo. Kev tsis sib haum xeeb tuaj yeem ua rau muaj teeb meem xws li overheating lossis cua sov tsis txaus. Kev tswj kom zoo ntawm cov teeb meem flash yog qhov tseem ceeb kom ua tiav cov welds zoo ib yam thiab zoo.
- Material Incompatibility: Siv cov ntaub ntawv tsis sib xws rau lub vuam taub qab vuam tuaj yeem ua rau sab nraud tsis xws luag thiab vuam tsis ua haujlwm. Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm cov ntsiab lus melting thiab thermal conductivity, uas tuaj yeem ua rau muaj teeb meem xws li fusion tsis tiav, tawg, thiab brittle welds. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv uas sib haum rau ib leeg kom muaj kev vam meej.
Hauv kev xaus, kev nkag siab txog qhov tsis xws luag sab nraud morphologies hauv flash butt vuam yog qhov tseem ceeb rau kev ua kom zoo thiab kev ntseeg siab ntawm cov pob qij txha. Kev npaj kom zoo, kev ua kom zoo, kev tswj xyuas siab, kev tu electrode, thiab kev tswj ntawm qhov flashing tsis yog qhov tseem ceeb rau kev txo qis sab nraud thiab ua kom zoo welds. Los ntawm kev hais txog cov teeb meem no, cov tuam txhab lag luam tuaj yeem txhim kho tag nrho cov kev ua tau zoo thiab ua haujlwm ntev ntawm lawv cov txheej txheem flash pob tw.
