ERW (Electric Resistance Welded kav), yog dav siv nyob rau hauv ntau yam lag luam xws li roj thiab roj, dej, kev tsim kho, thiab lwm yam. ERW cov txheej txheem tsim khoom yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom uas ua kom cov kav ntev thiab kev ntseeg siab ntawm cov kav dej no.
Thawj kauj ruam hauv ERW cov txheej txheem tsim khoom yog kev npaj cov khoom siv raw, uas suav nrog kev xaiv cov hlau zoo. Cov kauj ruam tom ntej yog pub cov hlau strips rau hauv cov txheej txheem ntawm cov menyuam uas ua cov strips rau hauv ib lub raj cylindrical. Cov txheej txheem no yog hu ua strip edge milling process.
Thaum cov hlau strips tau tsim rau hauv cov duab cylindrical, lawv tau welded siv hluav taws xob tam sim no. Cov txheej txheem no yog hu ua hluav taws xob tsis kam vuam txheej txheem. Cov hluav taws xob tam sim no tsim cov cua sov, uas ua rau cov npoo ntawm cov hlau nplaum, tsim kom muaj kev sib raug zoo.
Tom qab cov txheej txheem vuam, cov khoom siv ntau dhau raug tshem tawm siv cov txheej txheem trimming, uas ua kom ntseeg tau tias cov kav dej muaj qhov sib xws. Tom qab ntawd, cov kav dej tau dhau los ntawm chav ntsuas qhov ntsuas uas txuas ntxiv cov yeeb nkab mus rau qhov xav tau loj. Thaum kawg, cov kav dej raug txiav mus rau qhov ntev uas yuav tsum tau ua thiab raug rau ntau yam kev ntsuam xyuas kom ntseeg tau tias lawv lub zog thiab kav ntev.
ERW cov txheej txheem tsim cov yeeb nkab yog ib txoj hauv kev ua tau zoo thiab raug nqi ntawm kev tsim cov kav dej uas tau siv dav rau ntau yam kev siv. Cov txheej txheem ua kom ntseeg tau tias cov kav dej ua tau zoo thiab tuaj yeem tiv taus qhov hnyav thiab qhov kub thiab txias.
Hauv kev xaus, ERW cov txheej txheem tsim cov yeeb nkab yog qhov tseem ceeb ntawm cov txheej txheem tsim khoom, thiab nws yuav tsum tau ua kom tiav qib siab thiab ua tib zoo saib kom meej. Cov txheej txheem no ua lub luag haujlwm tseem ceeb hauv kev ua kom cov kav dej muaj txiaj ntsig zoo thiab tsim nyog rau ntau yam kev siv.
