1. Kusanthula kapangidwe ka mankhwala: njira yowunikira mankhwala, njira yowunikira zida (chida cha infrared CS, spectrometer yowerengera molunjika, zcP, etc.). ① Mamita a infrared CS: Unikani ma ferroalloys, zopangira zitsulo, ndi C ndi S muzitsulo. ②Kuwerenga molunjika: C, Si, Mn, P, S, Cr, Mo, Ni, Cn, A1, W, V, Ti, B, Nb, As, Sn, Sb, Pb, Bi mu zitsanzo zambiri. ③N-0 mita: Kusanthula kwamafuta a N ndi O.

2. Chitoliro chachitsulo miyeso ya geometric ndi kuyendera mawonekedwe:
① Kuyendera makulidwe a chitoliro chachitsulo: micrometer, ultrasonic makulidwe gauge, zosachepera 8 mfundo kumapeto onse ndi kujambula.
② Chitoliro chachitsulo m'mimba mwake ndi kuyang'ana kwa ovality: caliper, vernier caliper, ring gauge, kuyeza mfundo yaikulu ndi mfundo yochepa.
③Kuyendera kutalika kwa chitoliro chachitsulo: muyeso wa tepi wachitsulo, muyeso wamanja ndi wodziwikiratu.
④ Kuyang'ana kopindika kwa chitoliro chachitsulo: Gwiritsani ntchito chowongolera, mulingo (1m), geji yomveka, ndi waya wochepa thupi kuyeza kupindika pa mita ndi kupindika kwa kutalika konse.
⑤ Kuyang'ana kwa chitoliro chachitsulo kumapeto kwa bevel ndi m'mphepete mwake: wolamulira wapakati ndi mbale yotsekera.

3. Chitsulo chitoliro pamwamba kuyendera khalidwe: 100%
① Kuyang'ana pamanja pamanja: mikhalidwe yowunikira, miyezo, chidziwitso, zolembera, kuzungulira kwa chitoliro chachitsulo.
② Kuwunika kosawononga: a. Akupanga cholakwa kuzindikira UT: Ndi tcheru pamwamba ndi mkati ming'alu zolakwika za yunifolomu zipangizo zosiyanasiyana zipangizo. Standard: GB/T 5777-1996. mlingo: C5 mlingo.
b. Kuzindikira zolakwika za Eddy ET: (electromagnetic induction): imakhudzidwa makamaka ndi zolakwika zooneka ngati dzenje (zobowo). Standard: GB/T 7735-2004. mlingo: B mlingo.
c. Magnetic particle MT ndi kuyendera kwa maginito kutayikira: Kuyang'ana kwa maginito ndikoyenera kuzindikira zolakwika zapamwamba ndi pafupi ndi pamwamba pa zida za ferromagnetic. Standard: GB/T 12606-1999. mlingo: C4 mlingo
d. Electromagnetic akupanga cholakwa kuzindikira: Palibe cholumikizira sing'anga chomwe chimafunikira, ndipo chingagwiritsidwe ntchito pakutentha kwambiri, kuthamanga kwambiri, kuzindikirika kwa chitoliro chachitsulo choyipa pamwamba pazida.
e. Kuyesa kwapakati: fluorescence, utoto, kuzindikira zolakwika zapaipi zachitsulo.

4. Kuyang'anira kasamalidwe kazitsulo: ① Kuyesa kwamphamvu: kuyeza kupsinjika ndi kusinthika, ndikuzindikira mphamvu (YS, TS) ndi index ya pulasitiki (A, Z) ya zinthuzo. Zitsanzo zautali ndi zopingasa, zigawo za mapaipi, zooneka ngati arc ndi zozungulira (￠10, ￠12.5). Small m'mimba mwake woonda khoma zitsulo chitoliro, lalikulu m'mimba mwake wandiweyani khoma zitsulo chitoliro, atakhazikika n'zotsimikizira kutalika. Zindikirani: Kutalika kwa chitsanzo pambuyo pa kusweka kumagwirizana ndi kukula kwa chitsanzo GB/T 1760.
②Kuyesa kwamphamvu: CVN, mtundu wa C, mtundu wa V, ntchito J mtengo J/cm2. Zitsanzo zokhazikika 10×10×55 (mm) Zitsanzo zosagwirizana ndi 5×10×55 (mm)
③Kuwuma mayeso: Brinell kuuma HB, Rockwell kuuma HRC, Vickers kuuma HV, etc.
④Kuyesa kwa hydraulic: kuthamanga kwa mayeso, nthawi yokhazikika, p=2Sδ/D

5. Njira yoyendera ntchito yoyendera chitoliro chachitsulo:
① Mayeso oyala pansi: chitsanzo chozungulira chooneka ngati C (S/D>0.15) H= (1+2)S/(∝+S/D)
L=40 ~ 100mm Deformation coefficient pa utali wagawo =0.07 ~0.08
② Kuyesa kwa mphete: L = 15mm, palibe ming'alu, ndiyoyenerera
③ Mayeso okulitsa ndi kupindika: tepi yapakati ndi 30°, 40°, 60°
④ Mayeso opindika: amatha kusintha mayeso a flattening (mapaipi akulu akulu)

6. Kusanthula kwachitsulo kwa chitoliro chachitsulo:
①Kuwunika kwamphamvu kwambiri (kusanthula kwapang'onopang'ono): zophatikiza zopanda zitsulo 100x GB/T 10561 Kukula kwambewu: giredi, kusiyana kwamakalasi. Gulu: M, B, S, T, P, F, AS. Decarburization wosanjikiza: mkati ndi kunja. Njira A mlingo: Kalasi A - sulfide, Kalasi B - okusayidi, Kalasi C - silicate, D - oxidation ozungulira, Gulu la DS.
②Mayeso otsika kwambiri (kusanthula kwakukulu): maso amaliseche, galasi lokulitsa 10x kapena kuchepera. a. Njira yoyesera etching acid. b. Sulfur print inspection njira (chubu choyendera chopanda kanthu, chowonetsa mawonekedwe ocheperako ndi zolakwika, monga kutayirira, tsankho, thovu lozungulira, makutu akhungu, mawanga oyera, zophatikizika, etc. tsitsi, Utali, ndi kugawa.
