Ukuqinisekisa ikhwalithi yama-welds emishini yokushisela izinqe kubaluleke kakhulu ekuthembekeni nasekuphepheni kwezakhiwo ezishiselwe.Lesi sihloko sicubungula izindlela nezindlela ezahlukahlukene ezisetshenziselwa ukuhlola ikhwalithi yokushisela emishinini yokushisela izinqe, igcizelela ukubaluleka kwezinqubo zokuhlola ngokuqinile.
- Ukuhlola Okubonakalayo:
- Ukubaluleka:Ukuhlola okubonakalayo kuyindlela eqonde kakhulu futhi yokuqala yokuhlola ikhwalithi yokushisela.
- Inqubo:Abahloli abaqeqeshiwe bahlola ngokubuka ilunga elishiselwe ukubona ukukhubazeka okubonakalayo njengokuqhekeka, ama-undercuts, ukuhlangana okungaphelele, noma ukubola okweqile.Lokhu kuhlola kuvame ukwenziwa ngokushesha ngemva kokushisela futhi futhi ngemva kwanoma yikuphi ukwelashwa okudingekayo kwangemva kokushisela.
- Ukuhlolwa kobukhulu:
- Ukubaluleka:Ukunemba kobukhulu kubalulekile ekuhloniphekeni kwesakhiwo, okwenza ukuhlolwa kobukhulu kubaluleke kakhulu.
- Inqubo:Kuthathwa izilinganiso ezinembile ukuze kuqinisekiswe ukuthi ubukhulu be-weld buhambisana nokucaciswa kwedizayini.Lokhu kubandakanya ukuhlola ububanzi be-weld, ukujula, kanye nejiyomethri iyonke.
- Ukuhlola Okungabhubhisi (NDT):
- Ukubaluleka:Amasu e-NDT avumela ukuhlolwa okuningiliziwe ngaphandle kokulimaza isihlanganisi esishiselwe.
- Inqubo:Izindlela ezahlukahlukene ze-NDT, ezinjengokuhlolwa kwe-ultrasonic, ukuhlolwa kwe-radiographic, ukuhlolwa kwezinhlayiya kazibuthe, nokuhlola ukungena kodayi, zingasetshenziswa ukuthola amaphutha angaphakathi, ukungaqhubeki, noma ukungahambi kahle kwezinto ekushiseleni.
- Ukuhlolwa Komshini:
- Ukubaluleka:Ukuhlolwa kwemishini kuhlola amandla kanye ne-ductility ye-weld.
- Inqubo:Ukuhlolwa kwe-tensile, impact, kanye nokuqina kuwukuhlola kwemishini okuvamile okusetshenziselwa ukuhlola ikhwalithi yokushisela.Lokhu kuhlola kunquma ikhono le-weld lokumelana namandla asetshenzisiwe kanye nokumelana kwayo nokuphuka.
- Ukuhlolwa kwe-Macroscopic:
- Ukubaluleka:Ukuhlolwa kwe-Macroscopic kunikeza umbono oseduze wesakhiwo sangaphakathi se-weld.
- Inqubo:Amasampula ahlukene e-weld ayalungiswa futhi ahlolwe ngaphansi kwesibonakhulu ukuze kuhlolwe ukwakheka okusanhlamvu, izindawo ezithinteke ekushiseni, kanye nokuba khona kwanoma yikuphi ukukhubazeka noma okudidayo.
- Ukuhlolwa kwe-Microscopic:
- Ukubaluleka:Ukuhlolwa kwe-Microscopic kunikeza ileveli elingcono kakhulu lemininingwane mayelana ne-microstructure ye-weld.
- Inqubo:Izingxenye ezacile ze-weld ziyapholishwa futhi zihlaziywe ngaphansi kwesibonakhulu esinamandla amakhulu ukuze kuhlolwe izici zensimbi ze-weld, okuhlanganisa usayizi wokusanhlamvu, okuqukethwe okufakiwe, nokusabalalisa kwesigaba.
- Ukuhlolwa kwe-Ultrasonic (UT):
- Ukubaluleka:I-UT iphumelela kakhulu ekutholeni iziphambeko ze-weld zangaphakathi.
- Inqubo:Amagagasi e-Ultrasonic adluliselwa ku-weld, futhi amagagasi abonisiwe ayahlaziywa.Noma yikuphi okudidayo esakhiweni sokushisela kukhonjwa ngokusekelwe kumaphethini e-echo.
- Ukuhlolwa kwe-Radiographic (RT):
- Ukubaluleka:I-RT inikeza umbono obanzi wesimo sangaphakathi se-weld.
- Inqubo:I-X-ray noma imisebe ye-gamma idlula endaweni yokushisela, idala isithombe kufilimu noma kumtshina wedijithali.Ukungaqhubeki okufana nama-voids, inclusions, noma imifantu kubonakala njengethunzi ku-radiograph.
Ukuhlola ikhwalithi yokushisela emishinini yokushisela izinqe kuyinqubo enezici eziningi esebenzisa izindlela ezihlukahlukene, okuhlanganisa ukuhlola okubonakalayo, ukuhlola ubukhulu, ukuhlola okungabhubhisi, ukuhlolwa komshini, ukuhlolwa kwe-macroscopic kanye ne-microscopic, ukuhlolwa kwe-ultrasonic, nokuhlolwa kwe-radiographic.Ngayinye yalezi zindlela zisebenzisa inhloso ethile ekuhloleni ubuqotho besakhiwo se-weld, umsindo wangaphakathi, nokuhambisana nokucaciswa kwedizayini.Ngokusebenzisa ngokuqinile lezi zindlela zokuhlola, abashiseli nabahloli bangaqinisekisa ukuthi amajoyinti ashiselwe ahlangabezana nezindinganiso zomkhakha kanye nezidingo zokuphepha, okunikela empumelelweni yonke kanye nokuthembeka kwezakhiwo ezishiselwe ekusetshenzisweni okuhlukahlukene.
