Kuve nechokwadi chemhando yewelds mubutt welding michina yakakosha pakuvimbika uye kuchengetedzeka kwezvivakwa zvakasungwa. Ichi chinyorwa chinotarisa munzira dzakasiyana siyana uye matekiniki anoshandiswa kuongorora kunaka kwewelding mumashini ekuweldhesa butt, ichisimbisa kukosha kwekuomarara kwekuongorora.
- Visual Inspection:
- Kukosha:Kuongorora kwekuona ndiyo yakatwasuka uye yekutanga nzira yekuongorora welding mhando.
- Maitiro:Vatariri vakadzidziswa vanoongorora nemeso majoini akasungwa kuti aone kuremara kwakadai sekutsemuka, undercuts, fusion isina kukwana, kana porosity yakawandisa. Kuongorora uku kunowanzoitwa pakarepo mushure mekuputira uye zvakare mushure meyese inodiwa post-weld kurapwa.
- Dimensional Inspection:
- Kukosha:Kurongeka kwedimensional kwakakosha pakurongeka kwechimiro, zvichiita kuti kuongororwa kwedimensional kuve kwakakosha.
- Maitiro:Kuyerwa chaiko kunotorwa kuve nechokwadi kuti zviyero zveweld zvinoenderana nedhizaini. Izvi zvinosanganisira kuongorora hupamhi hweweld, kudzika, uye geometry yakazara.
- Kuedza Kusina Kuparadza (NDT):
- Kukosha:NDT matekiniki anobvumira kuongororwa kwakadzama pasina kukuvadza iyo welded joint.
- Maitiro:Dzakasiyana nzira dzeNDT, dzakadai seye ultrasonic bvunzo, radiographic kuyedzwa, magineti particle kuyedzwa, uye dhayi inopinda mukati mekuyedza, inogona kushandiswa kuona hurema hwemukati, discontinuities, kana zvinhu zvisiri izvo mu weld.
- Mechanical Testing:
- Kukosha:Mechanical test inoongorora simba uye ductility ye weld.
- Maitiro:Tensile, kukanganisa, uye kuomarara bvunzo dzakajairika mechani bvunzo dzinoshandiswa kuongorora weld mhando. Miedzo iyi inoona kugona kweweld kumirisana nemasimba akaiswa uye kuramba kwayo kuputsika.
- Macroscopic Examination:
- Kukosha:Kuongorora kweMacroscopic kunopa tarisiro yepedyo yemukati we weld chimiro.
- Maitiro:Muchinjikwa-sectional samples ye weld inogadzirwa uye inoongororwa pasi pemaikorosikopu kuti iongorore chimiro chezviyo, nzvimbo dzine kupisa, uye kuvepo kwehumwe hurema kana hurema.
- Microscopic Examination:
- Kukosha:Microscopic bvunzo inopa yakatonyanya nhanho yeruzivo nezve weld's microstructure.
- Maitiro:Zvikamu zvitete zveweld zvinokwenenzverwa nekuongororwa pasi pemakorosikopu ane simba guru kuti aongorore masimbi ewald, kusanganisira saizi yezviyo, kubatanidza, uye kugovera kwechikamu.
- Ultrasonic Testing (UT):
- Kukosha:UT inoshanda zvakanyanya pakuona mukati weld defects.
- Maitiro:Ultrasonic masaisai anopfuudzwa mukati meweld, uye mafungu anoratidzwa anoongororwa. Chero zvisizvo mune weld chimiro zvinoonekwa zvichibva pane echo mapatani.
- Radiographic Testing (RT):
- Kukosha:RT inopa maonero akazara emamiriro emukati we weld.
- Maitiro:X-rays kana gamma rays inopfuudzwa kuburikidza neweld, ichigadzira mufananidzo pafirimu kana dhijitari detector. Discontinuities senge voids, inclusions, kana kutsemuka kunoratidzika semumvuri paradiograph.
Kuongorora mhando yewelding mumashini ekuwelda inzira ine mativi mazhinji inoshandisa nzira dzakasiyana siyana, kusanganisira yekutarisa yekuona, dimensional cheki, isingaparadze kuyedza, mechaniki bvunzo, macroscopic uye microscopic bvunzo, ultrasonic bvunzo, uye radiographic bvunzo. Imwe neimwe yeaya matekiniki anoshanda chakanangana chinangwa mukuongorora kutendeseka kweiyo weld, kunzwika kwemukati, uye kuenderana nemagadzirirwo ezvakatemwa. Nekushandisa zvine hungwaru nzira dzekuongorora idzi, mawelder nevatarisi vanogona kuve nechokwadi chekuti majoini akasungwa anozadzisa zviyero zveindasitiri uye zvinodiwa zvekuchengetedza, zvichibatsira mukubudirira kwese uye kuvimbika kwezvimiro zvakashongedzwa mumashandisirwo akasiyana.
