Ukuhlolwa kwe-metal weld kubhekisa kwinkqubo yokuvavanya umgangatho wee-welded joints ngokusebenzisa ubuchwepheshe obahlukeneyo bokuvavanya. Ukuhlolwa komgangatho we-weld yikhonkco eliphambili lokuqinisekisa ukhuseleko kunye nokuthembeka kwezakhiwo zobunjineli. Ngezantsi, umxholo ophambili wokuhlolwa komgangatho we-weld ucaciswe ngokucwangcisiweyo ukusuka kubukhulu bokuhlolwa okubonakalayo, uvavanyo lwepropathi yoomatshini, kunye novavanyo lwe-macroscopic kunye ne-microscopic.
1.Uhlolo olubonakalayo (Uvavanyo lweMagnetic Particle)
Yenza uhlolo olubonakalayo ukuze ujonge umphezulu we-weld ukuze ubone iziphene ezifana neentanda, imingxunya yomoya, ukufakwa kwe-slag, kunye nokuhlanganiswa okungaphelelanga; linganisa ubukhulu obuquka ububanzi, ukuphakama, ukuqinisa i-weld, kunye nokungahambi kakuhle ukuqinisekisa ukuthotyelwa kweemfuno zoyilo. Okwangoku, sebenzisa i-magnetic particle tester ukuze ufumane iziphene zomphezulu kunye nomphezulu okufutshane kwizinto ze-ferromagnetic, sebenzisa ii-penetrant testing agents ukuze ufumane iziphene zomphezulu (umz., imingxunya yomoya, imingxunya) kwizinto ezingenamingxunya, sebenzisa i-ultrasonic thickness gauge ukuvavanya ukuqinisa i-weld, i-base metal thinning okanye iziphene zangaphakathi, kwaye usebenzise i-weld surface roughness tester ukuze uvavanye ukuba umgangatho womphezulu we-ground welds uyahlangabezana nemigangatho.
2.Uvavanyo lweMacroscopic kunye neMicroscopic (iMicroscope yoBunzulu bokungena kwe-Optical kunye neMicroscope yeMetallographic)
Uvavanyo lwe-macroscopic lubandakanya ukusebenzisa i-optical microscope ukujonga iimpawu ze-macrostructure zeendawo ezifana ne-weld fusion zone kunye ne-heat-challenge zone. Isebenza ngokulula kwaye inokuchonga ngokukhawuleza iziphene ezibonakalayo kwi-welds, nto leyo eyenza ifaneleke ukuhlolwa kwangaphambili kweemveliso ezinkulu.
Uvavanyo lwe-microscopic lubandakanya ukujonga ulwakhiwo lwe-microscope lwee-welds kusetyenziswa i-metallographic microscope ukuvavanya umgangatho we-welding kunye nobukhulu bendawo echaphazelekileyo bubushushu. Lukwajonga neziphene ezifana nokushisa kakhulu nokutsha.
3.Uvavanyo lwePropati yoMechanical (uMatshini woVavanyo lokuThamba kunye noVavanyo loBulukhuni beVickers)
Uvavanyo lwepropathi yoomatshini luvavanya ngokupheleleyo ukusebenza kwe-weld ngokusebenzisa iimvavanyo zokuxinana (zokulinganisa amandla kunye ne-plasticity), iimvavanyo zokugoba (zokuqinisekisa i-plasticity kunye nokuqina), iimvavanyo zempembelelo (zokuvavanya ubunzima bempembelelo), kunye novavanyo lobunzima (zokulinganisa ukusasazwa kobunzima).
Ngexesha lenkqubo yokudibanisa, isinyithi esisisiseko, isinyithi esihlanganisiweyo kunye nendawo echaphazelekileyo bubushushu idlula kumjikelo onzima wobushushu, nto leyo ebangela utshintsho olukhulu kwisakhiwo se-micro kunye nokwakheka okulandelayo kwemimandla enokusasazwa kobunzima obungalinganiyo. Ngovavanyo lobunzima beVickers, i-gradient yobunzima bengingqi nganye yejoyinti ehlanganisiweyo inokulinganiswa ngokuchanekileyo, nto leyo ebonelela ngesiseko sesayensi sokwenza ngcono inkqubo, ulawulo lomgangatho kunye nohlalutyo lokungaphumeleli.
4. Ukufunyanwa kweziphene zangaphakathi ze-Ultrasonic (Isikhangeli seziphene kunye neGauge yoButyebi)
Izixhobo zokubona iimpazamo ze-ultrasonic kunye neegeyiji zobukhulu be-ultrasonic zisetyenziselwa ukuhlola iziphene zangaphakathi ezifana nokuqhekeka kunye nokufakwa kwe-slag.
