1. Nleba anya nkeikiaka dabara adaba: n'ozuzu, nlele anya bụ isi ụzọ. Site na nlele anya, a na-achọpụta na ntụpọ ọdịdị weld nke ọkpọkọ ọkpọkọ welded na-achọpụta site na iko 5-20 na-ebuli elu mgbe ụfọdụ. Dị ka undercut, porosity, weld bead, elu mgbape, slag nsonye, ​​ịgbado ọkụ penetration, wdg The mkpokọta akụkụ nke weld nwekwara ike tụrụ site weld detector ma ọ bụ template.

2. NDT maka ntinye aka: lelee ntụpọ dị ka ntinye slag, oghere ikuku na mgbawa na weld. Nyocha X-ray bụ iji X-ray were foto nke weld, dị ka ihe oyiyi na-adịghị mma si dị iji chọpụta ma enwere ntụpọ na weld, ọnụ ọgụgụ na ụdị ntụpọ. Ka ọ dị ugbu a, a na-eji nyocha X-ray, nnwale ultrasonic na nyocha magnetik. Mgbe ahụ, dị ka ngwaahịa teknuzu chọrọ, chọpụta ma weld ruru eru. N'ebe a, ebili mmiri na-egosipụta na ihuenyo. Site n'ịtụle na ịchọpụta ebili mmiri ndị a na-egosipụta na ebili mmiri nkịtị, enwere ike ikpebi nha na ebe ntụpọ. Nnwale Ultrasonic dị mfe karịa nyocha X-ray, yabụ ejirila ya mee ihe n'ọtụtụ ebe. Agbanyeghị, enwere ike ikpe nnwale ultrasonic naanị site na ahụmịhe ọrụ na enweghị ike ịhapụ ntọala nyocha. Mgbe a na-ebufe eriri ultrasonic na ntanetị ikuku igwe, ọ ga-agbaji wee gafee weld. Ọ bụrụ na enwere ntụpọ na weld, a ga-egosipụta beam ultrasonic na nyocha na anụ ọhịa bea. A pụkwara iji nyocha magnetik mee ihe maka ntụpọ dị n'ime na obere mgbawa na-adịghị omimi site na weld elu.

3. Mechanical onwunwe ule nke ikiaka oyiyi akwa: nondestructive ule nwere ike ịhụ pụta ụwa ntụpọ nke weld, ma ọ pụghị ịkọwa n'ibu Njirimara nke metal na okpomọkụ emetụta mpaghara weld. Mgbe ụfọdụ, a na-achọ ule nhụsianya, mmetụta na ịgbagọ maka nkwonkwo welded. Emere nnwale ndị a na bọọdụ. Ekwesịrị iji eriri ogologo ogologo nke cylinder wee were efere nnwale ahụ welded iji hụ na otu ọnọdụ ihe owuwu ahụ. Mgbe ahụ, a nwalere ihe eji arụ ọrụ nke efere ule. Na mmepụta bara uru, ọ bụ naanị nkwonkwo ịgbado ọkụ nke ọkwa ígwè ọhụrụ ka a na-anwale na nke a.

4. Nnwale Hydrostatic na ule pneumatic nke ihe eji eme ihe n'ikpere aka: maka arịa nrụgide dị mkpa ka a mechie, a na-achọ nyocha hydrostatic na ule pneumatic iji lelee ike nkedo na nrụgide nke welds. Usoro a bụ ịgbanye akpa ahụ n'ime nrụgide na-arụ ọrụ nke mmiri ma ọ bụ 1.25-1.5 ugboro na-arụ ọrụ nke gas (ọtụtụ n'ime ikuku) ruo oge ụfọdụ, wee nyochaa nrụgide nrụgide n'ime akpa ahụ, wee nyochaa ma ọ dị. bụ ihe ọ bụla leakage phenomenon, iji chọpụta ma weld ahụ ruru eru.
