▇ ▍ Inkcazo
Umbhobho wentsimbi odibeneyo wenziwa kusetyenziswa iipleyiti zentsimbi ezisicaba okanye imicu yentsimbi, kwaye inkqubo yawo yokwenza idala imithungo emzimbeni wayo. Ngokukodwa, xa kwenziwa imibhobho yentsimbi edibeneyo, ipleyiti yentsimbi okanye umcu uyagotywa uze emva koko udityaniswe ube yingqukuva, imilo yepayipi yendabuko okanye imilo yesikwere. Umbhobho we-LSAW, umbhobho we-SSAW kunye nombhobho we-ERW zonke ziipayipi zentsimbi ezidibeneyo kwaye zahlulwe ngokwendlela yokudityanisa. Umzekelo, umbhobho we-LSAW udityaniswe ngobude, kwaye umbhobho we-SSAW udityaniswe nge-spiral. Umbhobho we-ERW udityaniswe ngombane, nto leyo ephumela kumthungo ohamba ngaxeshanye emzimbeni wombhobho.

Iipayipi ezidityanisiweyo eziphindaphindayo zihlala zithe nkqo, kodwa iipayipi zentsimbi ezidityanisiweyo eziqhotyoshelweyo azidityanisiweyo ngokufuthi. Umbhobho wentsimbi odityanisiweyo ophindaphindayo ojikelezayo ojikelezayo wenziwa lusu kunye nesiphumo sokusondela komsinga ophindaphindayo emva kokuba ipleyiti yekhoyili eqengqelekayo eshushu yenziwe ngumatshini wokubumba, kwaye umphetho wetyhubhu engenanto uyafudunyezwa kwaye unyibilikiswe, kwaye ukuwelda koxinzelelo kwenziwa phantsi kwesenzo serola yokucinezela ukuze kufezekiswe imveliso. Umbhobho wentsimbi odityanisiweyo ophindaphindayo ojikelezayo wahlukile kwinkqubo eqhelekileyo yokuwelda yombhobho odityanisiweyo. Ukuwelda kwenziwe ngezinto ezisisiseko zomzimba westrip yentsimbi, kwaye amandla oomatshini angcono kunalawo ombhobho odityanisiweyo oqhelekileyo. Umphezulu uthambile, uchanekileyo, unexabiso eliphantsi, kwaye unokuphakama komthungo ophantsi, okuluncedo ekugqumeni kwe-3PE anti-corrosion coating.
▇ ▍Umbhobho weNtsimbi we-LSAW
I-arc efakwe kwi-longitudinal efakwe kwi-arc yenziwe ngokusebenzisa ipleyiti enye ephakathi netyebileyo njengezinto eziluhlaza, icinezele (iqengqeleka) ipleyiti yentsimbi kwi-mold okanye kumatshini wokwenza ibe yityhubhu engenanto, kusetyenziswa i-arc welding efakwe kwi-arc engenanto emacaleni amabini, kwaye yandise ububanzi. Ubungakanani bokutya kwepleyiti yentsimbi bunokulungiswa ngokuzenzekelayo ngokwemigangatho eyahlukeneyo yentsimbi, ubukhulu bodonga, kunye nobubanzi bepleyiti. Kwangaxeshanye, umsebenzi wokuhlawula ukuguqulwa uphepha ngempumelelo imiphumo emibi yokuguqulwa kwe-mold ekubunjweni kwaye uqinisekisa ukuba ubude obupheleleyo bepleyiti yentsimbi buthe tyaba ngexesha lenkqubo yokucinezela. Inyathelo lokutya liyafana ngexesha lokwenziwa, ukuqinisekisa ukuba ityhubhu ingenanto ijikelezile kwaye umda we-welding uthe tyaba. Imveliso egqityiweyo inoluhlu olubanzi lweenkcukacha, kwaye i-weld inobunzima obuhle, i-plasticity, i-uniformity, kunye ne-compactness. Inezibonelelo zobubanzi obukhulu bepayipi, ubukhulu bodonga lwepayipi, ukumelana noxinzelelo oluphezulu, ukumelana nobushushu obuphantsi, kunye nokumelana okunamandla kokugqwala.
▇ ▍Umbhobho weNsimbi we-SSAW
Umbhobho odibeneyo ojikelezayo (umbhobho we-SSAW, obizwa ngokuba yipayipi ye-HSAW). Umbhobho wenziwa ngetekhnoloji yokuwelda ye-arc engaphantsi komhlaba. Imibhobho edibeneyo ejikelezayo yenziwa kusetyenziswa iipleyiti ezincinci okanye ii-hot rolled coils, nto leyo enciphisa iindleko zazo zemveliso kakhulu. Umgca wokuwelda umile njenge-helix. Inkqubo yokuwelda ejikelezayo ivumela ukuveliswa kwemibhobho emikhulu efanelekileyo yokuthutha ioyile kunye negesi eninzi. Eminye imibhobho ye-SSAW yayinqunyelwe kwizicelo zoxinzelelo oluphantsi.
