Hazvina mhosva kuti iyo welding joint iripi, iko iko iko kuunganidza kwechiitiko chewelding. Kune vanotanga, zvinzvimbo zvakapfava ndiwo maekisesaizi ekutanga, kutanga neawo anotenderera obva aenda kune yakamisikidzwa maekisesaizi.
Iyo inofananidzira kune yakagadziriswa welding mupombi welding ndeye rotational welding. Fixed welding zvinoreva kuti mubatanidzwa we welding haugone kufamba mushure mekunge pombi yaunganidzwa. Munguva yewelding process, iyo welding chinzvimbo inoshanduka (yakatwasuka, yakatwasuka, kumusoro uye pasi).
Kutenderedza chiteshi chewelding zvinoreva kutenderedza chiteshi chewelding panguva yewelding kuitira kuti welding igone kuita welding munzvimbo yakanaka (imwe yakachinjika, yakatwasuka, kumusoro, kana pasi).
Muchokwadi, kutaura zviri nyore, majoini akaiswa welding ma welds akaiswa panzvimbo, anofananidzwa nemapombi akagadzirwa.
Iyo yakagadziriswa welding yekubatanidza inoreva kuti pombi haifambi uye welder inoita zvese-kutenderera welding. Kunyanya kana welding kumusoro, iyo welding nzira yakaoma kushanda, inoda yakakwirira tekinoroji zvinodiwa kune welder, uye inowanzoitika kune hurema. Kazhinji inovakwa pane pombi gallery;
Chiteshi chinotenderera chinobvumira pombi kutenderera, uye chinzvimbo chewelding chinenge chiri flat welding kana vertical welding. The welding operation iri nyore uye ine zvishoma zvikanganiso. Iyo inonyanya kuvakwa pasi kana pasi.
Panguva yekuongorora welding, kuitira kudzivirira zviteshi zvese zvinotenderera kuti zvisasarudzwa kuti zviongororwe uye kuwana chiyero chepamusoro chekupasa, zvinodikanwa kuti utarise zvisina tsarukano imwe chikamu chezviteshi zvakagadziriswa kuti ive nechokwadi chewelding mhando yepombi yese. Iyo "Pressure Pipeline Safety Technical Supervision Regulations-Industrial Pipelines" inotaura kuti chiyero chekuonekwa kweakagadziriswa welding majoini haisi pasi pe40%.
Mumamiriro ezvinhu akajairwa, tinoshandisa chiteshi chakagadziriswa sechiteshi chinofambiswa. Chiteshi chengarava chinotakurika chibatanidzwa chakagadzirwa nechekare chepombi. Chikamu chepombi chinogona kutamiswa kana kutenderedzwa kana pombi yagadzirwa kubva panzvimbo. Chiteshi chakamisikidzwa imunda-wakaiswa welded port, uye pombi haigone kufamba kana kutenderera panguva ino.
Mapaipi emhando dzemapaipi ekureba anonzi "nzvimbo dzakafa" uye anoda "100% radiographic inspection." Iyo yakafa yejoin welding angle yakaoma uye iyo welding mhando haisi nyore kuvimbisa.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Iyo yakagadziriswa welding port inoenderana neinotenderera welding port.
Iyo inotenderedza welding joint inoreva kuti panguva yepipeline prefabrication welding process, welding joint inogona kutenderedzwa pamadiro zvichienderana neakanyanya kugadzikana kona yewelding operation. Hunhu hwewelding hwakadzikama, saka mawelder anoda rudzi urwu rwejoinhi yewelding.
Nekudaro, mamwe majoini ekugadzira majoini anogona kungogadziriswa nekuda kwemamiriro esaiti kana kugumira kweiyo workpiece pachayo. Iyi ndiyo inonzi fixed welding joint. Kana iyo yakagadziriswa welding joint yakaiswa uye yakasungwa, pane imwe chete nzira yekubatanidza welding. Rudzi urwu rwekubatanidza welding rwakaoma kupinza uye runoda chikamu chepamusoro chekuyedza kusiri kuparadza.
Mune mamwe marongero ekuvaka kwepombi, chikamu cheyakagadziriswa weld joint inspection inotsanangurwa zvakajeka. Nekuda kwekuti makona eiyo yakagadziriswa welding majoini akasiyana, manual welding inochinja, uye kunaka kwemajoini ewelding kuchave nekukanganisa. Semuenzaniso, majoini akaiswa welding emapombi esimbi anoda kuti mawelder aite zvese-nzvimbo welding, izvo zvinoisa zvakanyanya kudiwa kune welders. Ehezve, vane hunyanzvi hwepamusoro uye mazinga ehunyanzvi. A good welder haana hanya.
Mukutonga kwekuvaka, nhamba yekuvhura yakagadziriswa inofanira kuderedzwa zvakanyanya sezvinobvira. Kune rumwe rutivi, inogona kudzora mhando yewelding, uye panguva imwe chete, inogonawo kuderedza nhamba yekuona maronda uye kuderedza mari.
