Welded simbi pombi iri seamed simbi pombi.Kugadzirwa kwayo ndeyekupeta chubhu isina chinhu (ndiro yesimbi uye simbi tambo) muchubhu ine inodiwa muchinjiko-chikamu chimiro uye saizi nenzira dzakasiyana dzekugadzira, uyezve kushandisa nzira dzakasiyana dzewelding kuti weld weld seam pamwe chete.Nzira yekuwana mapaipi esimbi.
Kuenzaniswa nesimbi isina musono pombi uye welded pombi, ine hunhu hwemhando yepamusoro yechigadzirwa, kunyanya ukobvu hwemadziro, midziyo mikuru yakapfava, diki diki, kuenderera mberi kwekushanda mukugadzira, kuchinjika kugadzirwa, uye yakafara chigadzirwa siyana yeyuniti.
Imwe, Iyo yekugadzira maitiro e spiral simbi pombi ingangoita seinotevera:
1. Izvo zvigadzirwa zve spiral simbi pombi ndeye strip simbi coil, welding waya uye flux.
2. Usati wagadzira, simbi yemucheka inogadziriswa, yakagadziriswa, yakarongwa, yakacheneswa pamusoro, inotakurwa uye isati yabhenda.
3. Iyo weld gap control kifaa inoshandiswa kuve nechokwadi chekuti weld gap inosangana nezvinodiwa zvekushongedza, uye iyo dhayamita yepombi, misalignment uye weld gap inodzorwa zvakanyanya.
4. Mushure mekucheka mupombi dzesimbi imwe chete, mapaipi matatu ekutanga esimbi ega ega anofanirwa kupinda muhurongwa hwekutanga hwekuongorora kuti utarise zvimiro zvemuchina, kuumbwa kwekemikari, mamiriro ekubatanidza mawelds, kunaka kwepamusoro kwepombi dzesimbi uye kuyedza kusingaparadzi. kuve nechokwadi chekuti nzira yekugadzira pombi inokodzera.Mushure meizvozvo, inogona kuiswa zviri pamutemo mukugadzirwa.
Chechipiri, yakatwasuka musono yakanyudzwa arc welded pombi:
Iyo yakatwasuka musono yakanyudzwa arc welded pombi (LSAW) inowanzo shandisa mahwendefa esimbi semidziyo yakabikwa, uye inopinda maitiro akasiyana ekugadzira mapombi akaiswa neaviri-mativi akanyudzwa arc welding uye post-welding dhayamita yekuwedzera.
Midziyo mikuru inosanganisira edge milling muchina, pre-bending muchina, kugadzira muchina, pre-welding muchina, dhayamita yekuwedzera muchina, etc. Panguva imwecheteyo, nzira dzekugadzira dzeLSAW pombi dzinosanganisira UO (UOE), RB (RBE), JCO. (JCOE), etc. Iyo ndiro yesimbi inotanga yakatsikirirwa muU chimiro mukufa kwekugadzira, uye yozotsikirirwa muO shape, uye ipapo mukati nekunze yakanyura arc welding inoitwa.Mushure mekuputika, dhayamita (Kuwedzera) kumagumo kana kureba kwese kunowanzonzi UOE welded pipe, uye iyo isina kuwedzera kwedhayamita inonzi UOE welded pipe.For UO welded pombi.Iyo ndiro yesimbi inokungurutswa kuita chimiro (Roll Bending), uye ipapo mukati nekunze yakanyura arc welding inoitwa.Pashure nomoto, dhayamita inowedzerwa muRBE welded pombi kana RBE welded pombi pasina dhayamita kuwedzera.Iyo ndiro yesimbi inoumbwa mukurongeka kweJCO-mhando, uye mushure mekucheka, iyo dhayamita inowedzerwa muJCOE welded pombi kana JCO welded pombi isina kuwedzera dhayamita.
UOE LSAW pombi yekugadzira maitiro:
Iwo matatu makuru ekuumba maitiro eUOE LSAW simbi yekugadzira pombi maitiro anosanganisira: simbi ndiro pre-kupeta, U kuumba uye O kugadzira.Maitiro ega ega anoshandisa yakakosha kuumba muchina kupedzisa maitiro matatu ekutanga-kupeta mupendero wesimbi ndiro, U kuumba uye O kuumba munhevedzano, uye kukanganisa ndiro yesimbi kuita denderedzwa chubhu.
JCOE LSAW pombi yekugadzira maitiro:
Kugadzira: Mushure mekutsika-nhanho-nhanho kutsika pamushini wekugadzira JC0, hafu yekutanga yesimbi ndiro inotsikirirwa kuita "J" chimiro, uye imwe hafu yesimbi ndiro inotsikirirwa kuita "J" chimiro kuti iumbe. a C” chimiro, uye pakupedzisira yakamanikidzwa kubva pakati kuitira kuti Igadzire yakavhurika "0" chimiro chubhu stock.
Kuenzanisa kweJCO uye UO nzira dzekuumba:
Kugadzira JCO ndiko kufambira mberi kwekumanikidza kuumba, iyo inoshandura maitiro ekugadzira simbi pombi kubva pamatanho maviri eUO kuumba kune akawanda-nhanho.Munguva yekugadzira, deformation yesimbi ndiro yunifomu, yakasara kushushikana idiki, uye pamusoro haabudisi makwara.
Mapaipi esimbi akagadziridzwa ane hukuru hwekuchinjika muhukuru uye hutsananguro hwehupamhi hwehupamhi hwemadziro uye ukobvu hwemadziro, uye hunogona kugadzira zvigadzirwa zvakakura uye zvidiki-zvidiki;inogona kugadzira hombe-dhayamita yakakwirira-simba gobvu-madziro esimbi pombi, uye inogonawo kugadzira Diki-dhayamita uye gobvu-yakavakirwa simbi pombi;kunyanya mukugadzirwa kwepombi dzepamusoro-soro dzakakomberedzwa nemadziro, kunyanya mapombi madiki uye epakati-dhayamita makobvu ane madziro, ane zvakanakira zvisingaenzaniswi pane mamwe maitiro.
Inogona kusangana nezvimwe zvinodiwa zvevashandisi maererano nesimbi yepombi yakatarwa.Mari yacho idiki, asi kugona kwekugadzira kwakadzikira, uye kuburitswa kwegore negore i100,000 kusvika 250,000 matani.
UO molding inoumbwa neU uye O nguva mbiri dzekumanikidza kuumbwa.Iyo inoratidzirwa nehukuru hukuru uye yakakwirira kubuda.Kazhinji, goho repagore rinogona kusvika mazana matatu ezviuru kusvika miriyoni matani, ayo anokodzera kugadzirwa kwemazhinji kweiyo imwe yakatarwa.
3. Sight musono high frequency welded pombi:
Yakatwasuka seam yakakwirira-frequency welded pombi (RW) ndeye kupisa uye kunyungudutsa mupendero wechubhu billet nekushandisa ganda mhedzisiro uye pedo nemhedzisiro yeyakakwira-frequency ikozvino mushure mekupisa-yakakungurutswa coil yaumbwa nemuchina wekugadzira, uye kudzvanywa. welding inoitwa pasi pechiito che extrusion roller kuti iwane kugadzirwa.
Welded simbi pombi, inozivikanwawo sewelded pombi, ipombi yesimbi yakagadzirwa nesimbi ndiro kana strip simbi mushure mekukwenya uye welding.Welded simbi pombi ine nyore kugadzirwa muitiro, yakakwirira kugadzirwa kunyatsoshanda, akawanda siyana uye nokurondedzerwa, uye shoma midziyo mari, asi simba rayo rakaderera kupfuura musono simbi pombi.
Kubva kuma1930s, nekukurumidza kusimudzira kugadzirwa kwemhando yepamusoro simbi yemhando yepamusoro uye kufambira mberi kwewelding uye tekinoroji yekuongorora, mhando yewelds yakaramba ichivandudzwa, uye mhando uye kutsanangurwa kwepombi dzesimbi dzakasungirirwa dzakawedzera zuva nezuva. .Seam simbi pombi.Welded simbi pombi dzakakamurwa dzakatwasuka musono welded pombi uye spiral welded pombi maererano chimiro weld musono.
Kupatsanurwa nenzira yekugadzira: process classification - arc welded pombi, yemagetsi kuramba welded pombi, (yakakwirira frequency, yakaderera frequency) gasi welded pombi, choto welded pombi.Iyo nzira yekugadzira iyo yakatwasuka seam welded pombi iri nyore, kugadzirwa kwakanaka kwakakwira, mutengo wakaderera, uye budiriro inokurumidza.Kusimba kwe spiral welded pombi kunowanzo kukwirira kupfuura iyo yakatwasuka seam welded pombi, uye iyo welded pombi ine dhayamita yakakura inogona kugadzirwa neyakamanikana billet, uye welded pombi dzine madhayamita akasiyana anogona kugadzirwa nehupamhi hwakafanana billet.Asi kana tichienzanisa nepombi yakatwasuka yehurefu hwakafanana, kureba kweweld kunowedzerwa ne30 ~ 100%, uye kukurumidza kwekugadzira kwakaderera.
