Welded yeeb nkab pib pib raws li qhov ntev, coiled ribbon ntawm steel hu ua skelp. Daim tawv yog txiav mus rau qhov xav tau ntev, uas ua rau daim ntawv sib dhos tiaj tus. Qhov dav ntawm daim ntawv ntawd' s luv luv xaus yuav dhau los ua cov yeeb nkab' s sab nraud ncig sab nraud, tus nqi uas tuaj yeem siv los xam nws qhov tshwm sim sab nraud taub.
Welded cov yeeb nkab yog tsim los ntawm kev ua cov khoom tiaj tus (cov kab xev, ntawv lossis phaj) rau hauv cov duab yam xav tau, hauv qhov no, ib txwm puag ncig. Thaum cov duab xav tau tiav lawm, lub zog siab los siv los ua kom cov hlau nyob ntawm thaj chaw ntawm qhov chaw sib dhos. Nws yog cov ntawv xyaw ua ke thiab tso cai rau cov khoom ua kom ruaj khov, sib sau ua ib qho weld hlaws. Lub zog hluav taws xob siab tuaj yeem yog hluav taws xob arc, ntshav ntshav arc, kab teeb ci laser, lossis txawm tias tus nqaj hlau hluav taws xob. Ua raws li qhov txuas weld hlaws yog feem ntau me ntsis tuab dua li cov hlau uas nyob ib sab thiab yuav tsum tau hloov kho kom phim lub hauv paus hlau tuab, thiab kho kom tsis txhob muaj qhov tsis zoo lub cev, tshuaj lom neeg thiab xeb tiv thaiv cov cwj pwm ntawm lub weld.
Thaum pib ntawm lub welded yeeb nkab tsim cov txheej txheem yog li ntawd hu ua slabs lossis billets yog nrum hauv lub tshuab zeb. Kev txiav txim siab ntawm sab nraud thiab phab ntsa tuab muaj ntau txoj kev sib txawv ntawm kev tsim cov kav hlau txuas thiab cov kav dej: Cov Hluav Taws Xob Kuj Siv Hluav Taws Xob (ERW), Fusion Vuam (EFW) thiab Ob Chav Rauv Arc Vuam (DSAW). Hauv ERW thiab EFW cov txheej txheem kev tsim cov kav dej txuas yog tsim los ntawm kub lossis txias dov phaj thiab vuam vuam. Txhawm rau ua kom sab nraud (OD) saum npoo ntawm qhov txuas welded yeeb nkab du thiab cov niaj hnub ua cov tshuab txiav uas hu ua txoj phuam qhwv caj dab yog siv los tshem lub weld flash. Caws pliav los ntawm sab hauv (ID) welded flash tseem tau. Nrog rau kev kho kom kub thaum kawg ntawm kev tsim cov txheej txheem weld qhov chaw ntawm lub tog raj steel tuaj yeem ua kom pom tsawg dua. Vim yog lub weld seam qis kev ua haujlwm siab tau tshaj tawm raws li ASME piv rau cov kav dej txuas. Feem ntau welded kav muaj tighter dimensional tolerances tshaj li seamless kav thiab tsis tshua muaj nqi yog tsim nyob rau tib yam.
