Chitoliro chaching'ono chokhala ndi m'mimba mwake chimatchedwanso chitoliro chaching'ono chokhala ndi chitsulo chosungunuka, chomwe ndi chitoliro chachitsulo chopangidwa ndi kuwotcherera mbale yachitsulo kapena chitsulo chachitsulo chitatha.The ndondomeko yaing'ono m'mimba mwake welded chitoliro n'zosavuta, dzuwa kupanga ndi mkulu, pali mitundu yambiri ndi specifications, ndi zipangizo mtengo ndi yaing'ono, koma mphamvu ambiri ndi otsika kuposa chitoliro chosasokonezeka zitsulo.Kuyambira m'ma 1930, ndi chitukuko mofulumira kupanga mosalekeza wa apamwamba Mzere zitsulo ndi kusintha kwa kuwotcherera ndi kuyendera luso, khalidwe la welds wakhala mosalekeza bwino, ndi zosiyanasiyana ndi specifications wa mipope yaing'ono-m'mimba mwake welded akhala akuchulukirachulukira. m'malo mochulukirachulukira minda opanda zitsulo chitoliro.Welded zitsulo chitoliro anawagawa molunjika msoko welded chitoliro ndi mulingo welded chitoliro monga mwa mawonekedwe a weld.

Zosowa zomwe zimagwiritsidwa ntchito popanga mapaipi ang'onoang'ono ang'onoang'ono ndi zitsulo zachitsulo kapena zingwe, zomwe zimagawidwa m'mapaipi otenthedwa ndi ng'anjo, mapaipi amagetsi amagetsi (kukana-welded), ndi mapaipi opangidwa ndi arc-weld chifukwa cha njira zawo zowotcherera.Pali mitundu iwiri ya welded chitoliro: molunjika msoko welded chitoliro ndi ozungulira welded chitoliro.Chifukwa cha mawonekedwe ake omalizira, amagawidwa m'mapaipi ozungulira ozungulira ndi mapaipi apadera (mabwalo, ophwanyika, etc.) opangidwa ndi welded.

Njira yopanga yaing'ono-m'mimba mwake welded chitoliro ndi yosavuta, mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira.Mphamvu ya mipope yowotcherera yozungulira nthawi zambiri imakhala yokwera kuposa mipope yowongoka yowotcherera.Mapaipi owotcherera okhala ndi mainchesi akulu amatha kupangidwa kuchokera ku ma billets ocheperako.Mapaipi opangidwa ndi ma diameter osiyanasiyana amathanso kupangidwa ndi ma billets amtundu womwewo.Komabe, poyerekeza ndi chitoliro chowongoka cha kutalika komweko, kutalika kwa seam weld kumawonjezeka ndi 30 mpaka 100%, ndipo liwiro lopanga ndilotsika.Chifukwa chake, mapaipi ang'onoang'ono ang'onoang'ono amawotcherera m'mimba mwake nthawi zambiri amakhala owongoka, ndipo mipope yowotcherera yokhala ndi mainchesi akulu nthawi zambiri imakhala yowotcherera.
