Chitsulo chitoliroKukula kwaukadaulo wopanga zidayamba ndi kuchuluka kwa kupanga njinga, kukula kwamafuta koyambirira kwa zaka za zana la 19, zombo ziwiri zankhondo zapadziko lonse lapansi, ma boilers, kupanga ndege, pambuyo pa nkhondo yachiwiri yamafuta otenthetsera kupanga, mafakitale ndi chifukwa chake chitukuko cha kubowola mafuta ndi gasi ndi zoyendera, mogwira kuyendetsa makampani zitsulo chitoliro mkati chitukuko cha mitundu, zokolola ndi khalidwe. Kawirikawiri zitsulo chitoliro mogwirizana ndi msonkhano njira, ogaŵikana zitsulo chitoliro chosakanizika ndi welded zitsulo chitoliro mitundu iwiri, tsopano makamaka atchule welded zitsulo chitoliro.
Welded zitsulo chitoliro ndi kuti welded zitsulo chitoliro, kupanga ake ndi chubu akusowekapo (mbale zitsulo ndi lamba zitsulo) ndi kufalikira kwa kupanga njira mapindikidwe ndi yokulungira mu ankafuna mtanda-Sectional mawonekedwe ndi kukula kwa chubu chubu, ndi zina zotero. gwiritsani ntchito njira zosiyanasiyana zowotcherera kuti muwotchererane ndikupeza njira yopangira chitoliro chachitsulo. Poyerekeza ndi chitoliro chosasunthika chachitsulo, chitoliro chowotcherera ali ndi mikhalidwe yolondola kwambiri, makamaka makulidwe a khoma, zida zosavuta zazikulu, ntchito yaying'ono, kugwira ntchito mosalekeza kupanga, kupanga zosinthika, mitundu yonse yamagulu a unit ndiye.
Njira yopangira mapaipi idzagawidwa kukhala: SSAW (Spirally Submerged Arc Welding); LSAW (Longitudinous Arc Welding); Electric resistance Welding (ERW) atatu.
I. msonkhano ndondomeko ya kozungulira zitsulo chitoliro ali pafupifupi motere
● Zopangira za chitoliro chachitsulo chozungulira ndi coil, waya wowotcherera ndi flux.
● Asanapange Mzere mutatha kusanjikiza, kudula, planing, kuyeretsa pamwamba, mayendedwe ndi kupindika.
● The kuwotcherera kusiyana kulamulira chipangizo ntchito kutsimikizira kuti kuwotcherera kusiyana amakwaniritsa zofunika kuwotcherera, komanso m'mimba mwake chitoliro, m'mphepete ndi kuwotcherera kusiyana ndi mosamalitsa ankalamulira.
● Pambuyo kudula mu chitoliro chimodzi zitsulo, gulu lililonse la chitsulo chitoliro mutu atatu kugwira okhwima dongosolo loyamba kuyendera, fufuzani katundu makina a weld, mankhwala zikuchokera, kusungunuka chikhalidwe, zitsulo chitoliro pamwamba khalidwe ndipo pambuyo nondestructive anayendera, onetsetsani kuti chitoliro. kupanga ndondomeko yoyenera, imayikidwa mu kupanga.
Awiri, mowongoka msoko womiza arc chitoliro
Chitoliro chowongoka cha arc welded chitoliro (LSAW) nthawi zambiri chimatenga mbale ngati zinthu, kudzera m'njira zosiyanasiyana zopangira, kutengera zowotcherera zambali ziwiri zomizidwa ndi mipiringidzo ndi njira zina zopangira zowotcherera.
Chida chachikulu ndikuumba makina, makina opindika, makina opangira, makina owotcherera, makina okulitsa kenako. Pakadali pano, pali UO (UOE), RB (RBE), JCO (JCOE) ndiyeno. Mbale mkati mwa kupanga nkhungu choyamba mbamuikha mu mawonekedwe U, kotero mbamuikha mu O mawonekedwe, choncho mkati ndi kunja kumizidwa arc kuwotcherera, kuwotcherera kawirikawiri pamwamba kapena kutalika wathunthu wa kukula (Kukulitsa) wotchedwa UOE welded chitoliro, osati Kukulitsa wotchedwa UO welded chitoliro. mbale ndi adagulung'undisa Kupinda zooneka, ndiye mkati ndi kunja kumizidwa arc kuwotcherera ikuchitika. Pambuyo kuwotcherera, m'mimba mwake ndi RBE welded chubu kapena RB welded chubu popanda kuwonjezera. mbale analengedwa mwa dongosolo la JcO-mtundu, ndipo pambuyo kuwotcherera, awiri kukodzedwa kwa JCOE welded chitoliro kapena JCO welded chitoliro popanda kuwonjezera.
Zitatu, molunjika msoko mkulu pafupipafupi welded chitoliro (RW) ndi yotentha adagulung'undisa koyilo pambuyo akamaumba makina, ntchito chodabwitsa magetsi ndi moyandikana zotsatira za mkulu pafupipafupi panopa, kotero mbola chubu ndi usavutike mtima ndi kusungunuka, pansi pa zochita za extrusion. kuwotcherera kuthamanga kwa roller kuti akwaniritse kupanga.
