Surface NDT nzira dzeyakatwasuka musono simbi yekusarudza misimboti: magineti iron pombi inofanirwa kushandiswa mune magineti particle test;isiri-ferromagnetic simbi inofanirwa kushandiswa mukuyedzwa kwekupinda.Kunonoka kutsemuka maitiro emajoini akasungwa, iyo yepamusoro inofanirwa kunge isiri yekuparadza kuyedza mushure mekudziya kutonhora kweimwe nguva;reheat cracking maitiro emajoini akaiswa, iyo yepamusoro inofanirwa kunge iri mukuyedza isingaparadzi uye post-weld kupisa kurapwa kamwe chete.

Surface isiri-inoparadza yekuyedza maapplication zvinoenderana neyakajairwa zvinodikanwa zvinoona zvinhu uye mashandisirwo zvakazara sezvinotevera:
(1) Nzvimbo yekunze yehubhu yemhando yekuongorora.
(2) Yakakosha butt weld surface defect yekuona.
(3) Yakakosha fillet pamusoro pekuremara kuona.
(4) Yakakosha socket weld uye jumper tee bazi pombi chirema kuona.
(5) Pipe inokotama pamusoro pechirema kuona.
(6) Iyo midziyo inowanzodzima kuona yakakura groove welded majoini.
(7) Iyo tembiricha yekugadzira iri pazasi zero kana isiri-austenitic Stainless simbi pombi beveling yakaonekwa 29 degrees Celsius.
(8) Izvo zvigadziro zvembiri-mativi weldment mushure me weld gouging gouging kuonekwa
(9) Paunenge uchishandisa oxyacetylene murazvo wekucheka jig welded mapaipi alloy kuomesa maitiro pakukuya zvikamu zvakakanganiswa.
