Welded chitoliroNthawi zambiri anawagawa molunjika msoko welded chitoliro ndi kozungulira welded chitoliro mitundu iwiri.

Njira yowotcherera

Kuchokera pakuwotcherera, njira yowotcherera yozungulira yozungulira yowotcherera ndi chitoliro chowongoka chachitsulo chowongoka ndi chokhazikika, koma chitoliro chowongoka chowotcherera chowongoka chidzakhala ndi chowotcherera chowoneka bwino cha t, kotero kuthekera kwa zowotcherera zowoneka bwino kumakhalanso bwino, ndipo t-wobowola msoko kuwotcherera otsalira kupsyinjika ndi lalikulu, kupanikizika mkhalidwe zitsulo weld nthawi zambiri mu njira zitatu kumawonjezera kuthekera kwa crack.Ndipo, malinga ndi malamulo a kumizidwa arc kuwotcherera ndondomeko, aliyense weld adzakhala ndi arc ndi arc. mu, koma aliyense molunjika msoko welded chitoliro pamene kuwotcherera girth, sangathe kukwaniritsa zinthu, motero pangakhale zambiri pa arc kuwotcherera zilema.

Mphamvu makhalidwe

Pamene kuthamanga mu chitoliro kupirira, kawirikawiri awiri chachikulu maganizo pa khoma, kuti zozungulira ndi axial nkhawa nkhawaδ.Synthetic weld stressδ,kuα ndiye ngodya ya helix ya chitoliro chowotcherera chozungulira.Spiral welded seam degree helix angle nthawi zambiri imakhala yopangira, ndipo spiral weld Longitudinal stress ndiye vuto lalikulu.Pansi pa kuthamanga komweko, chitoliro chozungulira chofanana ndi makulidwe a khoma la Longitudinal chikhoza kuchepetsedwa.

Hydrostatic kupasuka kwamphamvu

Ndi mayeso ofananira oyenera kutsimikizira chitoliro chowotcherera chozungulira ndi kukakamiza kwa zokolola zautali ndi kuthamanga kwapang'onopang'ono kuyeza ndi mfundo zongoyerekeza.pakufanana, kupatuka kuyandikira.Koma kaya zokolola nkhawa kapena anaphulika kuthamanga, anali m'munsi kuposa Longitudinal ozungulira welded.Kuphulika mayeso limasonyezanso kuti mlingo wa mapindikidwe mphete kozungulira wokometsedwa chitoliro kuphulika Longitudinal kwambiri kuposa pakamwa.Choncho anatsimikizira kuti ozungulira welded pulasitiki mapindikidwe mphamvu kuposa Longitudinal, kuphulika pakamwa zambiri kutsekereza phula, umene ndi kutambasuka kwa ozungulira weld kung'amba kuchokera amphamvu kumanga zotsatira chifukwa.

Kulimba ndi kutopa mphamvu

Mchitidwe wa chitukuko cha payipi ndi lalikulu m'mimba mwake ndi mphamvu mkulu.Ndi kuchuluka kwa mainchesi a chitoliro ndi kuchuluka kwa chitsulo, kumapangitsa kuti nsonga ya ductile fracture ikhale yowonjezereka.Ngakhale chitoliro cha spiral welded ndi chitoliro chowongoka chowongoka chili ndi mulingo womwewo, chitoliro chowotcherera chozungulira chimakhala cholimba kwambiri.Kufala mapaipi chifukwa kuchuluka kwa kusintha kwenikweni ntchito, chitoliro akukumana mwachisawawa alternating katundu kwenikweni.
