ERW chitoliro otentha kugulitsa mkulu khalidwe zitsulo chitoliro

ERW chitoliro ndi chitoliro chachitsulo chomwe msoko wake wowotcherera uli wofanana ndi njira yotalikirapo ya chitoliro chachitsulo. Kawirikawiri ogaŵikana metric magetsi welded zitsulo chitoliro, magetsi welded woonda-mipanda chitoliro, thiransifoma kuzirala chitoliro cha mafuta ndi zina zotero. Longitudinal welded chitoliro ali ndondomeko yosavuta kupanga, mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira. Mphamvu ya mipope yowotcherera yozungulira nthawi zambiri imakhala yayikulu kuposa mipope yowongoka ya msoko. Chopanda kanthu chocheperako chingagwiritsidwe ntchito kupanga mapaipi owotcherera okhala ndi mainchesi akulu a chitoliro, ndipo billet yokhala ndi m'lifupi mwake ingagwiritsidwenso ntchito kupanga mapaipi owotcherera okhala ndi ma diameter osiyanasiyana. Koma poyerekeza ndi chitoliro chowongoka cha kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30-100%, ndipo liwiro lopanga ndilotsika.
