1. Welded square chubu ndi dzenje lalikulu gawo zitsulo lalikulu chubu, amadziwikanso kuti dzenje ozizira mawonekedwe zitsulo.Amapangidwa ndi kupindika kozizira komanso kuwotcherera kwanthawi yayitali pambuyo pa chingwe chotenthetsera kapena chozizira kapena chozungulira ngati chitsulo chopanda kanthu chokhala ndi mawonekedwe apakati ndi kukula kwake.
Kuwonjezera thickening wa khoma makulidwe a wandiweyani-mipanda lalikulu chubu, ngodya kukula ndi m'mphepete flatness kufika kapena kuposa mlingo wa kukana welded ozizira anapanga lalikulu chubu.Kukula kwa ngodya ya R nthawi zambiri kumakhala pakati pa 2 ndi 3 kuchulukitsa kwa khoma..Malinga ndi zosowa za makasitomala, titha kupanganso machubu a R-angle square a kukula kofunikira ndi makasitomala;
2. Machubu a Square Seamless square chubu ndi chingwe chachitali chachitali chokhala ndi gawo lobowo ndipo mulibe zolumikizira m'mphepete mwake.Ndi chubu lalikulu lomwe limapangidwa ndi kutulutsa chubu chopanda msoko kudutsa mbali 4 za nkhungu.Chigawo cha square chubu chili ndi dzenje ndipo chimagwiritsidwa ntchito mochuluka.Amagwiritsidwa ntchito pamayendedwe amadzimadzi, kuthandizira ma hydraulic, kapangidwe ka makina, sing'anga ndi kutsika, kuthamanga kwa boiler, chubu chosinthira kutentha, gasi, petroleum ndi mafakitale ena.Ndi wamphamvu kuposa welded ndipo sadzasweka.
