1. Nheyo yakakosha yearc welding ne electrodes
Pakugadzwa uye welding yemapaipi ane dhayamita isina kunyanyokura (senge pazasi 610mm) uye urefu hwepombi haina kureba zvakanyanya (senge pazasi 100km), electrode arc welding inofanira kutorwa seyokutanga sarudzo.Muchiitiko ichi, electrode arc welding ndiyo yakanyanya hupfumi Welding nzira.
Zvichienzaniswa neatomatiki welding, zvinoda midziyo shoma uye vashandi, mutengo wekugadzirisa wakaderera, uye boka rekuvaka rine ruzivo.
Electrode arc welding yakashandiswa kuisirwa uye welding kweanopfuura makore makumi mashanu.Akasiyana-siyana maelectrode uye nzira dzakasiyana dzekushanda dzakakura mune tekinoroji.Nhamba huru yedata, kuongororwa kwehutano kuri nyore.
Ehe, kune welding yemhando yepamusoro-yesimba giredhi simbi mapaipi, kutarisisa kunofanirwa kubhadharwa kune kusarudzwa uye kutonga kwewelding tsvimbo uye maitiro ekugadzirisa.Kana welding inoteedzera zvakajairwa pombi yakatarwa AP1STD1104-2005 "Welding yepombi nemichina ine hukama), shandisa mawelder ane hunyanzvi akadzidziswa uye akaedzwa.Kana 100% radiographic inspection ichiitwa, zvinokwanisika kudzora chiyero chekugadzirisa chese welds pazasi 3%.
Nekuda kwemutengo wakaderera uye kugadzirisa.Yakabatana nemhando yakavimbiswa, electrode arc welding yanga iri sarudzo yekutanga yevazhinji makondirakiti epurojekiti munguva yakapfuura.
2. Yakanyura arc otomatiki welding yakakosha musimboti
Sezvambotaurwa, iyo yakadzika arc otomatiki welding yemapombi inoitwa mumapombi welding zviteshi zvakagadzirirwa mapombi.Kana mapaipi maviri akaiswa pedyo nesaiti (double pipe welding), nhamba ye welds pamutsara mukuru inogona kuderedzwa ne 40% kusvika ku50%, iyo inopfupisa zvikuru kutenderera kwekuisa.
Kushanda kwepamusoro uye hupamhi hwepamusoro wearc otomatiki welding yekuisa welding zviri pachena, kunyanya kune mapaipi ane dhayamita rakakura (pamusoro pe406mm) uye ukobvu hwemadziro hunodarika 9.5mm, kana nzvimbo yekuisa yakareba, nekuda kwezvikonzero zvehupfumi, Kazhinji, nzira otomatiki yakanyura arc welding inotariswa kutanga.
Zvakadaro, vhoti imwe chete ndeyekuti mugwagwa wekutakura mapaipi maviri unokwanisa here, kuti mamiriro emigwagwa anobvumira here, uye kuti pane zvisungo zvekutakura mapaipi maviri akareba kupfuura 25m.Zvikasadaro, kushandisa otomatiki arc welding kuchave kusina zvazvinoreva.
Naizvozvo, kune mapaipi akareba ane dhayamita inodarika 406mm uye kukora kwemadziro makuru, kana pasina matambudziko mukufambisa uye mamiriro emumugwagwa, nzira yekutsikisa mapaipi maviri kana matatu ane otomatiki akanyura arc welding ndiyo yakanakisa sarudzo kune makondirakiti eprojekiti.
3.Flux cored wiresemi-otomatiki welding yekutanga musimboti
Yakasanganiswa ne electrode arc welding, flux cored waya semi-otomatiki welding inzira yakanaka yekuzadza welding yekuzadza welding uye yekuvharira welding yehombe-diameter uye gobvu-yakavakirwa simbi pombi.
Chinangwa chikuru ndechekushandura machinjiro ewelding kuti ive inoenderera yekugadzira modhi, uye welding ikozvino density yakakwira kupfuura iyo ye electrode arc welding, waya yewelding inonyungudika nekukurumidza, uye kugona kwekugadzira kunogona kuita 3 kusvika ka5 kune iyo electrode arc. welding, saka kugona kwekugadzira kwakakwira.
Parizvino, self-shielded flux-cored wire semi-otomatiki welding inoshandiswa zvakanyanya mumunda pombi welding nekuda kwekupokana kwayo nemhepo, kuderera kwehydrogen zvirimo muweld, uye kugona kwakanyanya.Ndiyo nzira yakasarudzika yekuvaka pombi munyika yangu.
4. Kunyanya kukosha kweMIG automatic welding
Kumapaipi akareba ane dhayamita yakakura kupfuura 710mm uye kukora kwemadziro makuru, kuitira kuwana hunyanzvi hwekuvaka hwepamusoro uye hwemhando yepamusoro, MIGA otomatiki welding inowanzoonekwa pekutanga.
Iyi nzira yave ichishandiswa kwemakore makumi maviri nemashanu, uye yave ichizivikanwa zvakanyanya kumapaipi makuru-dhayamita pasi rose, kusanganisira mapoka epombi yepamhenderekedzo yegungwa nepasi pemvura, uye inowanzokosheswa muCanada, Europe, Middle East nedzimwe nyika nematunhu.
Chikonzero chakakosha nei nzira iyi ichishandiswa zvakanyanya ndechekuti mhando yekuisa uye welding inogona kuvimbiswa, kunyanya kana welding mapaipi akasimba.
Nekuda kwekudzikira kwehydrogen yeiyi nzira yewelding, uye zvinodikanwa zvakanyanya pakuumbwa nekugadzirwa kwewaya yewelding, kana kuomarara kunodiwa kwakakwira kana pombi inoshandiswa kutakura acidic media, welding epamusoro-giredhi simbi mapaipi neichi. nzira inogona kuwana yakagadzikana welding mhando.
Zvakakosha kuziva kuti kana zvichienzaniswa ne electrode arc welding, mari musimbi arc welding system yakakura, uye zvinodiwa zvemichina nevashandi zvakakwirira.Iyo inodiwa yekuchengetedza yepamusoro inofanirwa kutariswa, uye zvishongedzo uye gasi rakasanganiswa rinosangana nezvinodiwa zvehutsanana zvinofanirwa kutariswa.supply.
