Pamwamba NDT njira zowongoka zosankhidwa zazitsulo zowongoka: chitoliro chachitsulo cha maginito chiyenera kugwiritsidwa ntchito poyesa tinthu tating'ono;Chitsulo chosakhala ferromagnetic chiyenera kugwiritsidwa ntchito poyesa kulowa.Kuchedwa akulimbana chizolowezi cholumikizira mafupa, pamwamba ayenera kukhala sanali zowononga kuyezetsa pambuyo kuwotcherera kuzirala nthawi zina;Kutenthetsanso chizolowezi chophwanyika cha mfundo zowotcherera, pamwamba payenera kukhala pakuyezetsa kosawononga ndi chithandizo cha kutentha pambuyo pa weld kamodzi.

Ntchito zoyesa zoyeserera zosawononga molingana ndi zofunikira zomwe zimazindikira zinthu ndikugwiritsa ntchito motere:
(1) An pamwamba pa chubu zinthu khalidwe anayendera.
(2) Kuzindikira vuto la matako owotcherera.
(3) Kuzindikira zolakwika za fillet pamwamba.
(4) Kuzindikira vuto la socket weld ndi jumper tee nthambi ya chitoliro.
(5) Kuzindikira chilema cha chitoliro cha chitoliro.
(6) Zakuthupi amakonda kuzimitsa kuzindikira zazikulu poyambira welded mfundo.
(7) The kapangidwe kutentha ndi pansi pa ziro kapena sanali austenitic zosapanga dzimbiri chitoliro beveling wapezeka 29 digiri Celsius.
(8) Zopereka za kuwotcherera mbali ziwiri pambuyo kudziwika kwa weld gouging gouging
(9) Pamene ntchito oxyacetylene lawi kudula jig welded mapaipi aloyi kuumitsa chizolowezi pa akupera mbali chilema kuzindikira.
