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. Njira yopanga yaing'ono yowotcherera m'mimba mwake ndiyosavuta, kupanga kwachangu ndikwambiri, pali mitundu yambiri ndi mawonekedwe, ndipo mtengo wa zida ndi wocheperako, koma mphamvu zambiri ndizotsika kuposa chitoliro chachitsulo chosasinthika. 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 ya mipope yaing'ono-m'mimba mwake welded akhala akuchulukirachulukira. m'malo mochulukirachulukira minda yopanda chitsulo chitoliro. Welded zitsulo chitoliro anawagawa molunjika msoko welded chitoliro ndi mulingo welded chitoliro monga mwa mawonekedwe a weld.

Zopanda kanthu zomwe zimagwiritsidwa ntchito popanga mapaipi ang'onoang'ono ang'onoang'ono ndi zitsulo zazitsulo kapena zingwe, zomwe zimagawidwa m'mapaipi otenthedwa ndi ng'anjo, mapaipi amagetsi amagetsi (kukana-welded), ndi mapaipi opangidwa ndi arc-welded 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 komanso opangidwa mwapadera (mabwalo, ophwanyika, etc.) opangidwa ndi welded.

The ndondomeko 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 otsekemera okhala ndi ma diameter osiyanasiyana amathanso kupangidwa ndi ma billets omwe ali m'lifupi mwake. 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.
