Spiral welded chitolirokupanga kumagwiritsa ntchito koyilo yopiringizika yotentha.The aloyi zili koyilo nthawi zambiri m'munsi kuposa makalasi ofanana a mbale zitsulo, kuwongolera weldability wa mulingo welded chitoliro.Chifukwa cha kugubuduza malangizo ozungulira welded chitoliro koyilo si perpendicular kwa chitoliro olamulira malangizo, ndi mng'alu kukana kwa muzungulira welded chitoliro zipangizo.

Chifukwa cha ntchito yapadera ya ozungulira chitoliro, pamene ozungulira welded chitoliro kuphulika zinachitika, weld anavutika maganizo ndi co-kupsyinjika ndi yaing'ono, kuphulitsa pakamwa nthawi zambiri si chiyambi cha wowotcherera ozungulira, choncho chitetezo apamwamba.Spiral weld pafupi ndi chilema ndi parallel spiral weld mphamvu ndi yaying'ono, kotero chiopsezo cha kukula sichoncho.

Chitoliro chachitsulo chimakhala ndi mphamvu yamkati, nthawi zambiri pakhoma pazigawo ziwiri zazikulu za mphamvu, kupanikizika kwa radial δY ndi axial stress δX.Kupanikizika kochokera ku weld δ = δY (l/4sin2α + cos2α) 1/2, yomwe, α ndi ngodya ya helix ya chitoliro chowotcherera.The helix ngodya ya ozungulira weld chitoliro zambiri madigiri 50-75, kotero mulingo weld lalikulu chifukwa nkhawa.Mu ntchito yomweyi pansi pa chitsenderezo cha m'mimba mwake wozungulira wowotcherera chitoliro khoma makulidwe akhoza kuchepetsedwa kwambiri, wozungulira chitoliro chomera akhoza kukhala yaing'ono caliber.
