Emkhakheni wokukhiqiza nokukhiqiza, ukwethembeka kwemishini yokushisela indawo yokumelana kubaluleke kakhulu. Le mishini idlala indima ebalulekile ekuhlanganiseni izinsimbi ndawonye, iqinisekisa ubuqotho besakhiwo semikhiqizo eminingi esihlangabezana nayo ekuphileni kwethu kwansuku zonke. Ukuqinisekisa ikhwalithi yokushisela amabala nokugcina ukusebenza kahle kwale mishini, izindlela zokuhlola ezingabhubhisi zibalulekile.
Isingeniso
I-Resistance spot welding, indlela esetshenziswa kakhulu embonini yezimoto, ye-aerospace, neyokwakha, ihilela ukuhlanganiswa kwezingcezu ezimbili zensimbi ngokusebenzisa ukushisa nokucindezela. Ikhwalithi yalawa mashisela ibalulekile, njengoba inquma ukuqina nokuphepha komkhiqizo wokugcina. Izindlela zokuhlola ezingabhubhi (i-NDI) ziye zavela njengethuluzi elibalulekile ekuhloleni ubuqotho bezindawo zokushisela ngaphandle kokudala umonakalo ezintweni ezishiselwe.
Ukuhlolwa kwe-Ultrasonic (UT)
Enye yezindlela ezisetshenziswa kakhulu ze-NDI zemishini yokushisela indawo yokumelana ukuhlolwa kwe-ultrasonic (UT). I-UT isebenzisa amaza omsindo wemvamisa ephezulu adluliswa ngokuhlanganyela kwe-weld. Lawa maza abuye abuyele emuva lapho ehlangabezana nokungahambi kahle okufana nama-voids noma imifantu ngaphakathi kokushisela. Ngokuhlaziya isikhathi esisithathayo ukuze lawa ma-echoes abuye kanye nobukhulu bawo, abahloli bangakhomba amaphutha angenzeka.
Ukuhlolwa kwe-Radiographic (RT)
Ukuhlolwa kwe-Radiographic kungenye indlela enamandla ye-NDI. Ngale ndlela, ama-X-ray noma imisebe ye-gamma iqondiswa nge-weld. Isithombe se-radiographic sibe sesikhiqizwa efilimini yezithombe noma umtshina wedijithali. Ukungaqhubeki ku-weld, njengokufakiwe noma i-voids, kubonakala njengethunzi ku-radiograph. Ochwepheshe abanekhono eliphezulu bangatolika lezi zithombe ukuze bahlole ikhwalithi yokushisela.
Ukuhlolwa Kwamanje kwe-Eddy (ECT)
Ukuhlola kwamanje kwe-Eddy kuwusizo ikakhulukazi ekutholeni amaphutha angaphezulu naseduze kwendawo yokushisela amabala. Isebenza ngokuyenga ama-eddy currents ku-conductive material kanye nezinguquko zokulinganisa ekuphatheni kukagesi okubangelwa ukukhubazeka. I-ECT iyindlela esheshayo futhi eguquguqukayo ekwazi ukuhlonza izinkinga ezinjengokuqhekeka, ukuqina, nokuhlukahluka kokuqina kwezinto.
Izinzuzo Zokuhlola Okungabhubhisi
Izinzuzo zokusebenzisa izindlela zokuhlola ezingonakali zemishini yokushisela indawo yokumelana ziyabonakala. Lezi zindlela zivumela ukutholwa kusenesikhathi kokulimala, ukuvimbela ukukhiqizwa kwe-subpar noma imikhiqizo okungenzeka ingaphephile. Ziphinde zehlise ukumosheka kwezinto ezibonakalayo futhi zonge isikhathi uma kuqhathaniswa nokuhlola okulimazayo, lapho i-weld ivivinywa ngokomzimba ukuze ihluleke.
Emhlabeni wokukhiqiza, ukunemba nokuthembeka kubaluleke kakhulu. Ukusetshenziswa kwezindlela zokuhlola ezingonakali zemishini yokushisela indawo yokumelana kuqinisekisa ukuthi imikhiqizo esithembele kuyo ukuphepha nokusebenza ihlangabezana nezindinganiso eziphakeme kakhulu. Ngokusebenzisa amasu afana nokuhlolwa kwe-ultrasonic, ukuhlolwa kwe-radiographic, nokuhlola kwamanje kwe-eddy, abakhiqizi bangagcina ubuqotho bezinto ezishiselayo, bathuthukise ikhwalithi yomkhiqizo, futhi ekugcineni, bathole ukwethenjwa amakhasimende abo.
