Weld ming'alu m'chombo choponderezedwa nthawi zambiri amakhala akuchedwa kusweka kozizira ndipo kugawa ndikofalikira kwambiri.Popanga chotengera choponderezedwa ndi kuphatikizika kwamunda ndi chidwi chapadera, koma chifukwa cha "kuchedwa" kwake, pansi pa kupsinjika koletsa, nthawi zambiri pakuwunika kwa chaka, zitha kupezekabe mochulukirapo.Apa sikufufuza ndende ya kupsinjika kwa m'deralo, kapena chithandizo cha kutentha sichitha nthawi yake, yunifolomu ndi zifukwa zina, pokhapokha pazifukwa zobisika kwambiri, ndipo mwina sizingawonekere pa njira yodziwira ming'alu ya workpiece idzakambidwa.Ming'alu yosweka yotereyi nthawi zambiri ndi galasi lokulitsa kapena maikulosikopu imatha kuwonedwa.Kukhalapo kwake sikungochepetsa mphamvu yowotcherera, komanso kupsinjika maganizo kudzatsogolera ku chatsopano, pamene workpiece ndi katundu, zomwe zimachititsa kuti mng'aluyo uwonongeke mofulumira, kuchititsa kuwonongeka kwa chigawo.Choncho, nthawi zina, ndi owopsa kuposa mitundu ina ya macroscopic crack.Poyang'ana chotengera choponderezedwa, momwe mungadziwire bwino ma microcracks, kuwongolera kuchuluka kwa ming'alu yaying'ono, yomwe imayikidwa muzowunikira zachidebe ndikuvulazidwa pamaso pa vuto lenileni, komanso momwe mungapezere ndikuwerengera zolakwika kuti zitheke. kukhazikitsa pulogalamu yokonzanso ndikofunika.

Kukula kofulumira kwa mafakitale amakono, pali mitundu yosiyanasiyana ya teknoloji yodziwira, yomwe ili ndi mphamvu zake ndi zofooka zake.Kotero momwe mungasankhire teknoloji yodziwika bwino kwambiri yodziwira ming'alu, njira zosiyanasiyana zodziwira ziyenera kufananizidwa poyamba kuti mudziwe bwino kwambiri teknoloji yoyenera yowunikira chilengedwe.Itha kugawidwa kukhala: kuyang'ana kowona (VT), njira yoyesera maginito (MT), njira yoyesera yolowera (PT), kuyesa kwa ultrasonic (UT), njira yowunikira ma radiographic (RT).

Pofuna kupititsa patsogolo kuzindikirika kwa ming'alu yaying'ono, ndi njira imodzi yokha yodziwira kuti pali zolepheretsa zambiri komanso zosiyidwa zomwe zingayambitse kusazindikirika.Kupyolera muzochita, timakhulupirira kuti kuvulaza kwakukulu kwa sitima yapakatikati komanso yothamanga kwambiri yoyezera ma microcracks kuyenera kukhala kugwiritsa ntchito njira zosiyanasiyana zodziwira.Oyang'anira zombo zoyendera ayenera kusanthula zinthu zinazake, kugwiritsa ntchito mokwanira njira zosiyanasiyana zozindikirira, ndikuwonetsa malo omwe apezeka;kufufuza ovulala ayeneranso kuthana ndi nkhani zenizeni, zomveka sayansi ntchito njira zosiyanasiyana zodziwira, cholinga chenicheni.
