Munyika yekugadzira maindasitiri, kunyanya muchikamu chesimba, mhando yewelds mukugadzirwa kwemapaipi yakakosha. Izvi zvinonyanya kukosha kumapaipi egasi, uko kuvimbika kweweld kunogona kureva musiyano pakati pekuchengetedzeka nenjodzi. Kufekitori yedu muCangzhou, Hebei Province, tinonzwisisa basa rakakosha rinoitwa nemhando yewelds mukuona kuvimbika uye kuchengetedzeka kwezvigadzirwa zvedu. Kambani yedu yakavambwa muna 1993 uye yakakura kusvika yasvika nzvimbo inosvika 350,000 square metres, pfuma yese inosvika RMB 680 miriyoni, uye vashandi vakazvipira 680.
Chimwe chezvinhu zvakakosha zvekufunga nezvazvo kana uchisanganisa mapaipi egasi rechisikigo imhando yetekinoroji yekusanganisa inoshandiswa.pombi yakasungirirwa yakatenderera, nzira inonyanya kushandiswa ndeyekushandisa welding yearc welding (SAW). Iyi nzira inodiwa nekuda kwekugona kwayo kugadzira weld dzakasimba, dzinogara kwenguva refu, uye dzemhando yepamusoro. Maitiro ekugadzira welding yearc welding anosanganisira kuumbwa kwearc pakati peelectrode inodyiswa nguva dzose ne workpiece, iyo inonyudzwa pasi pe granular flux. Izvi hazvingodziviriri weld kubva mukusvibiswa chete, asiwo zvinovandudza kunaka kweweld nekupa arc yakagadzikana uye kuderedza kupararira.
Kukosha kwepombiHunhu hwekuwelda haugone kupfuudzwa zvakanyanya. Mukufambisa gasi rechisikigo, chero kutadza kwekuwelda kunogona kukonzera njodzi huru, kusanganisira kudonha kwemvura, kuputika uye kukuvara kwezvakatipoteredza. Nokudaro, kuve nechokwadi chekuti maitiro edu ekuwelda anosangana nezvinodiwa zvepamusoro-soro chinhu chakakosha. Kuzvipira kwedu kune hunhu kunotanga nekusarudza zvinhu zvakagadzirwa uye kunoenderera mberi muchikamu chega chega chekugadzira, kusanganisira kuyedza kwakasimba uye kuongorora maweld.
Pachivako chedu cheCangzhou, tinoshandisa tekinoroji yepamusoro uye mainjiniya vane hunyanzvi kuona kuti maitiro edu ekupinza arc pasi pemvura anounza mhedzisiro yakanaka. Chikwata chedu chakadzidziswa kutarisa nekudzora zviyero zvekupinza zvakanyatsonaka, tichiona kuti weld yega yega inosangana nezvinodiwa zvakasimba zvinotsanangurwa nemitemo yeindasitiri. Kutarisisa uku kune zvakadzama hakungogadzirisi chete kunaka kwemapaipi edu egasi, asiwo kunoita kuti vatengi vedu vavimbe nezvigadzirwa zvedu kuti vatakure simba rakachengeteka uye rinoshanda.
Pamusoro pezvo, kunaka kweweld yemapaipi kunokanganisa zvakananga mashandiro uye hupenyu hwepombi.weld yechubhukuderedza mukana wekugadzirisa matambudziko uye kuwedzera hupenyu hwepombi, zvichizopedzisira zvachengetedza mari yevatengi vedu. Muindasitiri umo kuvimbika kwakakosha, kuisa mari mumhando yepamusoro yeweld hakusi kungosarudza chete; chinhu chinodiwa.
Mukupedzisa, kukosha kwekunamira kwemhando yemapaipi mukugadzirwa kwemapaipi egasi rechisikigo hakugoni kufuratirwa. Semugadziri anotungamira muindasitiri, kuzvipira kwedu kushandisa matekinoroji epamusoro ekunamira akadai sekunamira kwearc pasi pemvura uye kutarisa kwedu pakudzora mhando kunoita kuti tive shamwari inovimbwa nevatengi vedu. Neruzivo rwemakore anopfuura makumi matatu uye vashandi vakazvipira, tinoramba tichiisa pamberi kuchengetedzeka nekuvimbika kwezvigadzirwa zvedu, tichiona kuti tinosangana nezvinodiwa neindasitiri yesimba iri kuchinja. Sezvatinofambira mberi, tinoramba takatsiga mubasa redu rekupa mapaipi egasi rechisikigo emhando yepamusoro, nekuti kana zvasvika pakufambisa simba, mhando haisiyo chete yakakosha; asi inokosha.
