Kuyesa kosawononga ndiko kugwiritsa ntchito ma acoustic, optical, maginito ndi magetsi, popanda kuvulaza kapena kusokoneza kugwiritsa ntchito chinthu chomwe chili pansi pa ntchito ya chinthu chomwe chiyenera kuyang'aniridwa, kuti muwone kukhalapo kwa zolakwika kapena inhomogeneities mu chinthucho. kuyang'aniridwa, kupereka kukula kwa zolakwika, malo a zolakwika, chikhalidwe cha chiwerengero cha chidziwitso ndi zina zotero, ndiyeno kudziwa luso la chinthu chomwe chiyenera kuyang'aniridwa (mwachitsanzo, woyenerera kapena wosayenerera, moyo wotsalira. ndi zina zotero) njira zonse zaumisiri za nthawi wamba.
Njira zoyesera zosawononga zomwe zimagwiritsidwa ntchito: Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Liquid Penetration Testing (PT) ndi X-ray Testing (RT).
Kuyesa kwa Ultrasonic
UT (Ultrasonic Testing) ndi imodzi mwa njira zoyesera zosawononga makampani. Akupanga mafunde mu chinthu kukumana ndi zolakwika, gawo la phokoso mafunde adzawoneka, transmitter ndi wolandira akhoza kusanthula funde wonyezimira, akhoza mwapadera kuyeza molondola za zolakwika. Ndipo akhoza kusonyeza malo ndi kukula kwa zolakwika mkati, kudziwa makulidwe a zinthu.
Ubwino woyezetsa akupanga:
1, mphamvu yolowera ndi yayikulu, mwachitsanzo, muzitsulo pakuzindikira koyenera kwa mita imodzi kapena kuposerapo;
2, chifukwa cha zolakwika zamtundu wa ndege monga ming'alu, ma interlayers, ndi zina zotero, kuzindikira kukhudzidwa kwakukulu, ndipo amatha kudziwa kuya ndi kukula kwake kwa zolakwika;
3, zida zopepuka, zogwira ntchito zotetezeka, zosavuta kuzindikira zoyendera zokha.
Zoyipa:
Sizophweka fufuzani mawonekedwe ovuta a workpiece, amafuna mlingo wina wa kusalala kwa pamwamba anayendera, ndi wothandizila kugwirizana chofunika kudzaza kusiyana pakati kafukufuku ndi anayendera pamwamba kuonetsetsa chokwanira lamayimbidwe lumikiza.
Kuyendera kwa Magnetic Particle
Choyamba, tiyeni timvetsetse mfundo yoyendera maginito. Pambuyo magnetization wa zipangizo ferromagnetic ndi workpieces, chifukwa kukhalapo discontinuities, mizere maginito mphamvu pamwamba pa workpiece ndi pafupi ndi pamwamba kupotoza m'deralo, ndi kupanga kutayikira kumunda, adsorption wa maginito ufa ntchito pamwamba. za workpiece, kupanga zowoneka zowoneka maginito kufufuza mu kuwala koyenera, motero kusonyeza malo, mawonekedwe ndi kukula discontinuity.
Kugwiritsa ntchito ndi zolephera za kuyendera maginito ndi:
1, kuzindikira kolakwika kwa tinthu tating'onoting'ono ndikoyenera kuzindikira kutha kwa zinthu zomwe zili pamwamba pa ferromagnetic komanso pafupi ndi pamwamba ndi kukula kochepa kwambiri komanso mipata yopapatiza yomwe imakhala yovuta kuwona.
2, kuyang'ana kwa tinthu tating'onoting'ono kumatha kukhala mitundu yosiyanasiyana yozindikira magawo, komanso mitundu yosiyanasiyana yazigawo zomwe zimayenera kuzindikirika.
3, amatha kupeza ming'alu, inclusions, tsitsi, mawanga oyera, kupindika, kulekanitsa kozizira ndi zofooka ndi zina.
4, kuyang'ana kwa tinthu tating'onoting'ono sikungathe kuzindikira zida zosapanga dzimbiri zosapanga dzimbiri za austenitic ndi ma welds opangidwa ndi austenitic zosapanga dzimbiri zowotcherera maelekitirodi, ndipo sangathe kuzindikira mkuwa, aluminium, magnesium, titaniyamu ndi zida zina zopanda maginito. Pamwamba pa zokopa zosaya, zokwiriridwa mabowo ozama komanso ndi workpiece pamwamba ngodya zosakwana 20 ° delamination ndi kupindika n'zovuta kupeza.
Kuzindikira kulowa kwamadzi
Mfundo yayikulu yodziwira kulowa kwamadzimadzi, pamwamba pa gawolo imakutidwa ndi utoto wa fulorosenti kapena utoto wopaka utoto, mu nthawi yogwira ntchito ya capillary, madzi olowera amatha kulowa muvuto lotseguka; mutachotsa madzi ochulukirapo olowera pamwamba pa gawolo, ndiyeno wokutidwa ndi wopanga pamwamba pa gawolo.
Momwemonso, pansi pa zochita za capillary, wopanga adzakopa zolakwika pakusungidwa kwa permeate, kubwereranso kwa wopanga, mumtundu wina wa kuwala (kuwala kwa ultraviolet kapena kuwala koyera), zolakwika pamayendedwe a permeate zikuwonetsedwa, ( fulorosenti yachikasu yobiriwira kapena yofiira), kuti azindikire zolakwika za morphology ndi kugawa kwa boma.
Ubwino wozindikira malowa ndi awa:
1, amatha kuzindikira zinthu zosiyanasiyana;
2, ali ndi chidwi chachikulu;
3, chiwonetserochi ndichosavuta kugwiritsa ntchito, chosavuta kugwiritsa ntchito, chotsika mtengo chozindikira.
Ndipo kuipa koyeserera kolowera ndi:
1, osakhala oyenera kuyang'anira zinthu zotayirira zopangidwa ndi zida zogwirira ntchito ndi zida zogwirira ntchito;
2, kuyezetsa kulowa mkati kumangowona kugawa kwapadziko lapansi kwa zolakwika, ndizovuta kudziwa kuzama kwenikweni kwa zolakwika, chifukwa chake ndizovuta kuwunika kuchuluka kwa zolakwika. Zotsatira zozindikiridwa zimakhudzidwanso ndi wogwiritsa ntchito.
Zida zowotcherera za Xinfa zili ndi mawonekedwe apamwamba komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:Opanga Kuwotcherera & Kudula - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Kuwunika kwa X-ray
Chomaliza, kuzindikira kwa ray, chifukwa X-ray kudzera mu chinthu chowotchedwa chidzakhala ndi kutayika, makulidwe osiyanasiyana a zinthu zosiyanasiyana pa mlingo wawo wa kuyamwa ndi wosiyana, ndipo zoipa zimayikidwa kumbali ina ya chinthu chowotchedwa, chifukwa mphamvu ya kuwala. ndizosiyana ndikupanga zojambula zofananira, owunikira mafilimu amatha kutengera chithunzicho kuti adziwe ngati pali zolakwika mkati mwa chinthucho komanso momwe zolakwikazo zilili.
Kugwiritsa ntchito ndi malire a kuzindikira kwa ray:
1, tcheru kwambiri kuti muwone zolakwika za volumetric, zosavuta kuwonetsa zolakwikazo.
2, ray negative ndi yosavuta kusunga, pali traceability.
3, mawonekedwe a mawonekedwe ndi mtundu wa zolakwika.
4, kuipa sangathe kupeza m'manda kuya kwa zilema, pamene kudziwika makulidwe ochepa, zoipa ayenera kutumizidwa makamaka kusamba, ndipo thupi la munthu ali ndi vuto linalake, mtengo ndi apamwamba.
Mwachidule, akupanga, X-ray kuzindikira zolakwika ndizoyenera kuzindikira zolakwika zamkati; kumene akupanga kwa oposa 5mm, ndi mawonekedwe a wokhazikika mbali X-ray sangathe kupeza m'manda kuya kwa zolakwika, poizoniyu. Tinthu ta maginito ndi kuzindikira zolakwika zolowa ndizoyenera kuzindikira zolakwika pazigawo; Pakati pawo, kuzindikira zolakwika za tinthu tating'onoting'ono kumangopezeka pakuzindikira zida za maginito, ndipo kuzindikira cholakwika cholowa ndikungozindikira zolakwika zowonekera pamtunda.
