Kuve nechokwadi chewelding mhando kwakakosha mumashini ekuweldhesa butt kuvimbisa kutendeseka uye kuvimbika kwemajoini akasungwa. Nzira dzekuona dzakafanira dzakakosha kuti uone zvinogona kukanganisa uye kutsauka kunogona kukanganisa kuita weld. Ichi chinyorwa chinoongorora matekiniki anoshandiswa kuona kunaka kwewelding mumichina yewelding, ichiratidzira kukosha kwavo mukuchengetedza zviyero zvepamusoro zvekutendeseka kweweld.
- Visual Inspection: Kuongorora kwekuona ndiyo yakatwasuka uye yekutanga nzira yekuona welding mhando. Vane hunyanzvi hwekunama nevanoongorora vanonyatsoongorora chitarisiko che weld bead, vachitsvaga zvirema zvinooneka zvakaita sekutsemuka, porosity, kusakwana kusina kukwana, kana kukanganiswa kwebead profile.
- Penetrant Testing (PT): Penetrant bvunzo inzira isingaparadze yekuyedza (NDT) inosanganisira kuisa mvura inopinza kune weld pamusoro. Mushure menguva yakatarwa yekugara, yakawandisa inopinda inobviswa, uye mugadziri anoiswa kuti abudise chero anopinda akavharirwa mukukanganisa kwepamusoro. Iyi nzira inokwanisa kuona mitsetse yakanaka yepasi uye hurema husingaonekwe nemeso.
- Magnetic Particle Testing (MT): Magnetic particle bvunzo ndeimwe nzira yeNDT inoshandiswa kuona kuremara kwepasi uye pedyo-pamusoro. Iyo weld surface ine magnetized, uye magineti particles anoiswa. Kana kukanganisa kuripo, magineti particles anoungana uye anoita zviratidzo zvinooneka, zvichibvumira vaongorori kuti vaongorore kunaka kweweld.
- Ultrasonic Testing (UT): Ultrasonic yekuongorora ndeye volumetric NDT nzira inoshandisa yakakwirira-frequency ruzha masaisai kuongorora welds. Ultrasonic masaisai anopfuudzwa mukati meweld, uye chero hurema hwemukati kana discontinuities inoratidza masaisai kumashure kune anogamuchira. Iyi nzira yakanakira kuona kukanganisa kwemukati uye kuongorora weld kunzwika.
- Radiographic Testing (RT): Kuongororwa kweRadiographic kunosanganisira kupfuudza maX-rays kana gamma rays kuburikidza neweld uye kurekodha mhepo inotapuriranwa pafirimu kana madhijitari. Iyi nzira inogona kuona hurema hwemukati senge voids, inclusions, uye kushomeka kwefusion, ichipa ruzivo rwakadzama nezve weld yemukati chimiro.
- Tensile Testing: Tensile kuyedzwa kunosanganisira kuisa sampuli weld kune inodzorwa tensile simba kusvika yatyoka. Muedzo uyu unobatsira kuongorora weld's mechanic properties, senge yekupedzisira tensile simba nekurebesa, uye inopa manzwisisiro mukusimba kweiyo weld uye kuita kwayo.
- Bend Testing: Bend test inoshandiswa kuongorora ductility uye kunaka kwewelds. Chikamu cheweld chakakomberedzwa kune imwe radius kuona kana paine makatsemuka kana hurema hunooneka kunze. Muedzo uyu unonyanya kubatsira pakuona kukanganisa mune welds izvo zvingave zvisingaonekwe kubva mukuongororwa kwekuona.
Mukupedzisa, kuona mhando yewelding mumashini ekuweldhesa butt kwakakosha kuti ive nechokwadi chekuvimbika uye chepamusoro-chinoita majoini akasungwa. Kuongorora kwekuona kunopa yekutanga ongororo, nepo dzakasiyana-siyana dzisiri dzekuparadza nzira dzekuyedza senge PT, MT, UT, uye RT dzichipa humwe hwakadzama ruzivo mukutendeseka weld. Tensile kuyedzwa uye bend kuyedzwa kunopa ruzivo rwakakosha nezve weld's mechanic zvivakwa uye ductility. Nekushandisa nzira dzekuona idzi, vanogadzira welding uye vanoongorora vanogona kusimudzira mwero wakaomarara, kuona hurema hunogona kuitika, uye kuita sarudzo dzine ruzivo kugadzirisa chero nyaya, kuve nechokwadi chekuenderana uye kwakavimbika welding kuita mumashandisirwo akasiyana siyana.
