Ho na le mekhoa e mengata ea ho hlahloba boleng ba liphaephe tsa tšepe tse otlolohileng tse bophara bo boholo ba seam, tseo har'a tsona ho sebelisoang mekhoa ea 'mele. Tlhahlobo ea 'mele ke mokhoa o sebelisang liketsahalo tse itseng tsa 'mele ho metha kapa ho hlahloba. Tlhahlobo ea bofokoli ba ka hare ho thepa kapa liphaephe tsa tšepe tse otlolohileng tse bophara bo boholo ka bophara li sebelisa mekhoa e sa senyeheng ea tlhahlobo. Teko ea hajoale e sa senyeheng e kenyelletsa tlhahlobo ea matla a khoheli, tlhahlobo ea ultrasonic, tlhahlobo ea radiographic, tlhahlobo ea ho kenella, jj.

Tlhahlobo ea makenete
Ho lemoha bofokoli ba makenete ho khona ho bona feela likoli tse kaholimo le tse haufi le holim'a lipeipi tsa tšepe tse otlolohileng tsa seam se nang le seam se otlolohileng, 'me li ka sekaseka bofokoli ka bongata. Sebopeho le botebo ba mefokolo li ka hakanngoa feela ho latela boiphihlelo. Tlhahlobo ea Magnetic e sebelisa ho lutla ha makenete ho hlahisoang ke matla a khoheli ho hohela liphaephe tsa tšepe tsa ferromagnetic tse kholo tse otlolohileng tsa seam welded tšepe ho fumana likoli. Mekhoa e fapaneng ea ho lekanya ho lutla ha makenete e ka aroloa ka mokhoa oa likaroloana tsa makenete, mokhoa oa ho kenya makenete, le mokhoa oa ho rekota oa makenete. Har'a bona, mokhoa oa magnetic particle o sebelisoa haholo.

Tlhahlobo ea ho kenella
Tlhahlobo ea ho kenella ka hare e sebelisa thepa ea 'mele e kang ho kenella ha metsi a itseng ho sibolla le ho bonts'a mefokolo, ho kenyelletsa tlhahlobo ea mebala le tlhahlobo ea fluorescence, e ka sebelisoang ho lekola bofokoli holim'a lisebelisoa tsa ferromagnetic le tseo e seng tsa ferromagnetic.

Tlhahlobo ea radiographic
Ho lemoha liphoso tsa radiographic ke mokhoa oa ho lemoha liphoso o sebelisang litšoaneleho tsa mahlaseli ho phunyeletsa lisebelisoa le ho fokotsa lisebelisoa ho fumana mefokolo. Ho latela mahlaseli a fapaneng a sebelisetsoang ho lemoha mefokolo, e ka aroloa ka mefuta e meraro: ho lemoha bofokoli ba X-ray, ho lemoha phoso ea mahlaseli a gamma, le ho lemoha bofokoli ba mahlaseli a mangata. Ka lebaka la mekhoa e fapaneng ea ho bonts'a liphoso, mofuta o mong le o mong oa ho lemoha liphoso tsa radiographic o arotsoe ka mokhoa oa ionization, mokhoa oa ho shebella skrine oa fluorescent, mokhoa oa ho nka lifoto, le mokhoa oa thelevishene oa indasteri. Tlhahlobo ea radiographic e sebelisoa haholo ho hlahloba liphoso tse kang mapetsong, ho kenella ho sa fellang, li-pores, li-slag inclusions, le liphoso tse ling ka har'a tjheseletsa ea liphaephe tsa tšepe tse otlolohileng tsa seam se seholo se otlolohileng.

Ho lemoha liphoso tsa Ultrasonic
Ha maqhubu a ultrasonic a ata ka litšepe le mecha e meng ea litaba tse tšoanang, a tla bontšoa li-interfaces tsa mecha ea litaba e fapaneng, kahoo a ka sebelisoa ho hlahloba bofokoli ba ka hare. Ultrasound e khona ho bona mefokolo ho thepa efe kapa efe ea weldment le karolo efe kapa efe, mme e ka fumana ka botebo sebaka sa mefokolo, empa ho thata ho tseba hore na ke mofuta ofe, sebopeho le boholo ba likoli. Ka hona, ho lemoha phoso ea ultrasonic ea liphaephe tsa tšepe tse nang le bophara bo boholo bo otlolohileng tse otlolohileng hangata li sebelisoa hammoho le tlhahlobo ea radiographic.
