Lintho tse ka sehloohong tsa tlhahlobo ea boleng le mekhoa ealiphaephe tse se nang mokoloko:

1. Sheba boholo le sebōpeho sa phala ea tšepe

(1) Tlhahlobo ea botenya ba phala ea tšepe: micrometer, gauge ea botenya ba ultrasonic, e seng ka tlase ho lintlha tse 8 lipheletsong ka bobeli le ho rekota.

2. Ho hlahloba boleng ba holim'a liphaephe tse se nang moeli

(1) Tlhahlobo ea pono ea matsoho: tlas'a maemo a mabone a matle, ho ea ka litekanyetso, ho tšoaea phihlelo ea boitsebiso, fetola phala ea tšepe ho hlahloba ka hloko. Libaka tse ka hare le tse ka ntle tsa liphaephe tsa tšepe tse sa tsitsang ha lia lumelloa ho ba le mapetsong, mameno, maqeba, ho pota-pota le delamination.
(2) Teko e sa senyeheng tlhahlobo:

a. Ultrasonic flaw discovery UT: E na le kutloelo-bohloko ho mefokolo ea bokaholimo le kahare ea lisebelisoa tse fapaneng tse nang le thepa e ts'oanang.
b. Teko ea hona joale ea Eddy ET (electromagnetic induction) e ameha haholo ka liphoso tsa ntlha (tse nang le sekoti).
c. Teko ea Magnetic Particle MT le Flux Leakage: Teko ea Magnetic e loketse ho bona bofokoli ba bokaholimo le bo haufi ba thepa ea ferromagnetic.
d. Ho lemoha phoso ea elektromagnetic ultrasonic: Ha ho na mokhoa oa ho kopanya o hlokahalang, 'me o ka sebelisoa ho lemoha bofokoli ba lipeipi tsa tšepe tse phahameng, tse lebelo le holimo.
e. Ho lemoha liphoso tse phunyeletsang: fluorescence, coloring, ho lemoha mefokolo ea holim'a lipeipi tsa tšepe.

3. Tlhahlobo ea sebopeho sa lik'hemik'hale:tlhahlobo ea lik'hemik'hale, tlhahlobo ea lisebelisoa (seletsa sa CS sa infrared, spectrometer ea ho bala ka ho toba, NO sesebelisoa, joalo-joalo).

(1) Sesebelisoa sa Infrared CS: Hlahloba li-ferroalloys, lisebelisoa tse tala tsa tšepe, le likarolo tsa C le S ka tšepe.
(2) spectrometer ea ho bala ka ho toba: C, Si, Mn, P, S, Cr, Mo, Ni, Cn, Al, W, V, Ti, B, Nb, As, Sn, Sb, Pb, Bi ka lisampole tse ngata.
(3) Sesebelisoa sa N-0: tlhahlobo ea litaba tsa khase N, O.

4. Tlhahlobo ea ts'ebetso ea tsamaiso ea tšepe

(1) Teko ea tensile: lekanya khatello ea maikutlo le deformation, fumana matla (YS, TS) le index ea polasetiki (A, Z) ea thepa. Karolo ea liphaephe tsa longitudinal le transverse, sebopeho sa arc, sampole e chitja (￠10, ￠12.5) bophara bo nyane, lerako le tšesaane, bophara bo boholo, sebaka se teteaneng sa ho lekanngoa ha lebota. Tlhokomeliso: bolelele ba sampole ka mor'a ho robeha bo amana le boholo ba mohlala oa GB/T 1760.
(2) Tlhahlobo ea phello: CVN, mofuta oa notch C, mofuta oa V, mosebetsi oa J boleng J / cm2 sampuli e tloaelehileng 10 × 10 × 55 (mm) sampuli e sa tloaelehang 5 × 10 × 55 (mm).
(3) Teko ea boima: Brinell hardness HB, Rockwell hardness HRC, Vickers hardness HV, joalo-joalo.
(4) Teko ea Hydraulic: khatello ea teko, nako ea ho tsitsisa khatello, p=2Sδ/D.

5. Tlhahlobo ea ts'ebetso ea phala ea tšepe e se nang seamless

(1) Teko e bataletseng: sampole e chitja e bōpehileng joaloka C (S/D>0.15) H=(1+2)S/(∝+S/D) L=40～100mm, deformation coefficient per unit length=0.07～0.08
(2) Teko ea ho hula lesale: L=15mm, ha ho crack e tšoanelehang
(3) Teko ea ho phatloha le ho kobeha: tepi e bohareng ke 30°, 40°, 60°
(4) Teko ea ho kobeha: E ka nka sebaka sa teko e bataletseng (bakeng sa lipeipi tse bophara bo boholo)

6. Tlhahlobo ea metallographic ea pipe e se nang moeli
Teko e phahameng ea ho holisa (tlhahlobo ea microscopic), tlhahlobo ea kholo e tlase (tlhahlobo ea macroscopic) tlhahlobo ea moriri o bopehileng joaloka tora ho lekola boholo ba lijo-thollo tsa li-inclusions tse se nang tšepe, ho bonts'a lithane tse tlase le bofokoli (joalo ka ho hlepha, karohano, li-bubble tse tlase, jj. ), le ho hlahloba palo, bolelele le kabo ea moriri.

Sebopeho se phahameng se tlase (macro): Matheba a masoeu a bonoang, li-inclusions, li-bubble tse ka tlase ho letlalo, ho sotheha ha letlalo le delamination ha li lumelloe tlhahlobong e phahameng e tlase ea likarolo tsa tlhahlobo ea liphaephe tsa tšepe tse se nang moeli.

Mokhatlo oa matla a phahameng (microscopic): Hlahloba ka maekorosekopo ea elektronike ea matla a phahameng. Teko ea li-hairline: leka palo, bolelele le kabo ea moriri.

Sehlopha se seng le se seng sa lipeipi tsa tšepe tse se nang moroko tse kenang fekthering li tla tsamaea le setifikeiti sa boleng se pakang botšepehi ba likahare tsa sehlopha sa lipeipi tsa tšepe tse se nang moroko.
