Machubu amagetsi a welded welded (RW) amapangidwa ndi kuzizira kupanga chingwe chachitsulo chathyathyathya kukhala chubu chozungulira ndikuchidutsa mipiringidzo yambiri kuti apeze chowotcherera chotalikirapo.Mphepete ziwirizo zimatenthedwa nthawi imodzi ndi magetsi othamanga kwambiri ndikumangirira pamodzi kuti apange chomangira.Palibe zitsulo zodzaza zomwe zimafunikira pakuwotcherera kwakutali kwa ERW.
Palibe zitsulo zophatikizika zomwe zimagwiritsidwa ntchito popanga.Izi zikutanthauza kuti chitolirocho ndi champhamvu kwambiri komanso chokhazikika.
Msoko wa weld sungakhoze kuwonedwa kapena kumveka.Izi ndizosiyana kwambiri poyang'ana njira yowotcherera ya arc yomwe ili pansi pa madzi, yomwe imapanga mkanda wowoneka bwino womwe ungafunike kuchotsedwa.
Ndi kupita patsogolo kwa mafunde amagetsi othamanga kwambiri pakuwotcherera, njirayi ndiyosavuta komanso yotetezeka.
Mapaipi achitsulo a ERW amapangidwa ndi kukana kwapang'onopang'ono kapena kukana "kukaniza".Ndi mapaipi ozungulira omwe amawotcherera kuchokera ku mbale zachitsulo zokhala ndi ma welds aatali.Amagwiritsidwa ntchito kunyamula mafuta, gasi ndi zinthu zina zokhala ndi nthunzi, ndipo amatha kukwaniritsa zofunikira zosiyanasiyana zamphamvu komanso zotsika.Pakalipano, ili ndi malo ofunikira kwambiri pazambiri zamapaipi padziko lonse lapansi.
Panthawi yowotcherera chitoliro cha ERW, kutentha kumapangidwa pamene madzi akudutsa pamtunda wa malo otsekemera.Imatenthetsa mbali ziwiri zachitsulo mpaka m'mphepete umodzi ukhoza kupanga chomangira.Panthawi imodzimodziyo, pansi pa kukakamiza kophatikizana, m'mphepete mwa chubu chopanda kanthu chimasungunuka ndikufinyani pamodzi.
Nthawi zambiri ERW chitoliro pazipita OD ndi 24" (609mm), kwa miyeso yokulirapo chitoliro chidzapangidwa mu SAW.
