Munzvimbo yekugadzira nekugadzira, kuvimbika kwekupokana nzvimbo welding michina yakakosha. Michina iyi inoita basa rakakosha mukubatanidza simbi pamwechete, kuve nechokwadi chekuvimbika kwezvigadzirwa zvisingaverengeki zvatinosangana nazvo muhupenyu hwedu hwezuva nezuva. Kuti uvimbise kunaka kwenzvimbo welds uye kuchengetedza kushanda kwemakina aya, nzira dzisiri dzekuparadza dzekuongorora dzinokosha.
Nhanganyaya
Resistance spot welding, nzira inoshandiswa zvakanyanya mumaindasitiri emotokari, aerospace, uye ekuvaka, inosanganisira kusanganiswa kwezvidimbu zviviri zvesimbi kuburikidza nekushandiswa kwekupisa nekumanikidza. Hunhu hwema welds aya hwakakosha, sezvo ivo vachiona kusimba uye kuchengetedzeka kwechigadzirwa chekupedzisira. Nzira dzisina-kuparadza dzekuongorora (NDI) dzakabuda sechishandiso chakakosha pakuongorora kutendeseka kwemavara welds pasina kukonzeresa chero kukuvadza kune zvakasungwa zvinhu.
Ultrasonic Testing (UT)
Imwe yeanonyanya kushandiswa NDI nzira dzekudzivisa nzvimbo welding michina ndeye ultrasonic test (UT). UT inoshandisa yakakwira-frequency mafungu eruzha ayo anofambiswa kuburikidza neweld joint. Aya masaisai anodzokera kumashure kana asangana nezvisina kurongeka senge mavhodhi kana kutsemuka mukati meweld. Nekuongorora nguva inotora kuti maungira aya adzoke uye nekukura kwawo, vaongorori vanogona kuona hurema hunogona kuitika.
Radiographic Testing (RT)
Radiographic kuyedzwa ndeimwe nzira ine simba yeNDI. Nenzira iyi, X-rays kana gamma rays inotungamirirwa kuburikidza neweld. Mufananidzo weradiographic unobva wagadzirwa pafirimu remifananidzo kana digital detector. Discontinuities mu weld, senge inclusions kana voids, inoratidzika semumvuri paradiograph. Vanamazvikokota vane hunyanzvi vanogona kududzira mifananidzo iyi kuongorora weld mhando.
Eddy Current Testing (ECT)
Eddy yazvino yekuyedza inonyanya kubatsira pakuona pamusoro uye padyo-yepamusoro-yakakanganisika mune spot welds. Inoshanda nekukwevera eddy mafungu mune conductive zvinhu uye kuyera shanduko mumagetsi conductivity inokonzerwa nekuremara. ECT inzira inokurumidza uye inoshanda zvakasiyana-siyana inogona kuona zvinhu zvakaita sekutsemuka, porosity, uye kusiyanisa mukukora kwezvinhu.
Zvakanakira Non-Destructive Inspection
Zvakanakira kushandisa nzira dzisiri dzekuparadza dzekuongorora dzeresitorendi nzvimbo welding michina inoonekwa. Nzira idzi dzinobvumira kukurumidza kuonekwa kwehurema, kudzivirira kugadzirwa kwesubpar kana zvingangove zvisina kuchengetedzeka zvigadzirwa. Ivo zvakare vanoderedza kutambisa zvinhu uye kuchengetedza nguva zvichienzaniswa nekukuvadza kuyedzwa, uko weld inoedzwa mumuviri kutadza.
Munyika yekugadzira, kunyatsoita uye kuvimbika kwakakosha. Iko kushandiswa kwenzira dzisingaparadze dzekuongorora dzekudzivirira nzvimbo welding michina inovimbisa kuti zvigadzirwa zvatinovimba nazvo kuchengetedza uye kuita zvinosangana nepamusoro-soro zviyero. Nekushandisa matekiniki senge ultrasonic bvunzo, radiographic kuyedzwa, uye eddy ikozvino kuyedzwa, vagadziri vanogona kuchengetedza kutendeseka kwemawelds avo, kusimudzira mhando yechigadzirwa, uye pakupedzisira, kuwana kuvimba kwevatengi vavo.
