I-welding of flanges enkulu iyingxenye ehlanganisa amapayipi komunye nomunye, exhunywe ekugcineni kwepayipi, futhi ivalwe nge-gasket phakathi kwabo.Ukushisela ama-flange amakhulu, aziwa nangokuthi ama-welding flange, anezimbobo ku-flange yokushisela
Ukuxhumeka okuqinile kuwuhlobo lwengxenye emise okwediski evame ukutholakala kubunjiniyela bamapayipi.
Ijubane eliphezulu lokubumba (150-200mm/s) liyadingeka ekushiseleni kwensimbi nge-conductivity enhle yokushisa yama-flange amakhulu.Ngokuphathelene nensimbi efanayo, kukhona izinga lokushisa elikhulu endaweni yesixhumi esibonakalayo ngenxa yemvelo ebandayo yelunga
Udinga ukukhuphula isivinini sokuqamba.I-forging pressure i-Fu Fu ivame ukuboniswa ingcindezi yendawo ngayinye yeyunithi, okungukuthi, amandla okucindezela okukhangayo.Ubukhulu bengcindezi yokubumba kufanele buqinisekise ukuthi insimbi ewuketshezi ngaphakathi kwesixhumi esibonakalayo ingakhishwa
Ingena kwi-deformation ethile yepulasitiki.
Ngenxa yomsebenzi wawo ovelele wokungenisa izihambi, ama-flange amakhulu asetshenziswa kabanzi kumakhemikhali, ukwakhiwa, ukuhlinzekwa kwamanzi, i-drainage, i-petroleum, izimboni ezilula nezisindayo, iziqandisi, ukuthuthwa kwendle, amapayipi amanzi, amandla kanye nezimboni zokukhiqiza.
Cheng.
Uma ushisela ama-flanges amakhulu, uma ingcindezi ephezulu yokubumba incane kakhulu, ukuguqulwa akwanele futhi amandla ahlangene ayancipha;Uma ukucindezela okuphezulu kwe-forging kunamandla kakhulu, ukuguqulwa kuzoba kukhulu kakhulu, futhi okusanhlamvu kwekristalu kuzosonteka futhi kube nzima, okuzophinde kunciphise ukuqina komthelela welunga.
Ijubane lokukhanya elikhanyayo lizobangela ukwanda kwezinga lokushisa, ngakho-ke lapho izinsimbi zokushisela ezine-conductivity enhle yokushisa (ithusi, ama-alloys e-aluminium), ama-flange ensimbi akhethekile adinga ingcindezi enkulu yokubumba (150-400Mpa).
Ngaphezu kwemingcele yenqubo engenhla, izinga lokushisa lokushisa kanye nesikhathi sokushisa kufanele kucatshangelwe futhi ngaphambi kokushisa imingcele ye-welding yendawo ekhanyayo.Ukushisa kwangaphambi kokushisa kukhethiwe ngokusekelwe ku-workpiece cross-section kanye nomsebenzi wezinto ezibonakalayo.Lapho ushisela insimbi enekhabhoni ephansi,
700-900 degrees.
Ngokuvamile, i-arc welding ye-manual isetshenziselwa ukuthunga ama-flanges amakhulu, anemigqa yokuthungatha ye-arc engavamile kanye nokushiswa kalula nokuncishiswa konqenqema lwe-lining, engakwazi ukuqedwa ngisho nangomshini, okuholela ekubukekeni kwekhwalithi embi;2. Ngoba ngokuvamile uhlobo oluhlukile lwensimbi
I-welding yamanje enkulu, ukulawulwa okungalungile kwe-welding current, kanye nokuvela kalula kwe-undercutting noma i-welding engaphelele.Ukuze uthole ama-convex flange amakhulu, i-welding seam idinga ukucutshungulwa, ukuze kube nensimbi encane efakwe phakathi kwendandatho yocingo kanye ne-flange.
