Izindlela Ezihlukile Zokuhlola Zokuhlolwa Kwe-Post-Weld Yomshini Welding We-Nut Spot?

Ngemuva kokuphothula inqubo yokushisela usebenzisa umshini wokushisela amantongomane, kubalulekile ukwenza ukuhlolwa kwangemva kokushisela ukuze kuqinisekiswe ikhwalithi yokushisela nokuhambisana nezindinganiso ezithile.Kusetshenziswa izindlela eziningi zokuhlola ukuze kuhlolwe ubuqotho namandla amalunga okushisela.Lesi sihloko sinikeza ukubuka kabanzi kwamasu ahlukahlukene okuhlola asetshenziselwa ukuhlolwa kwe-post-weld emisebenzini yokushisela amantongomane.

1. Ukuhlola Okubonwayo: Ukuhlola okubonakalayo kuyindlela eyisisekelo neyokuqala yokuhlola ikhwalithi yokushisela.Umhloli onolwazi uhlola amajoyinti okushisela esebenzisa iso lenyama ukuze abone iziphambeko ezibonakalayo njengokungahambi kahle kwendawo, ukufana kobuhlalu be-weld, nezimpawu zokuhlangana okungaphelele noma ukuqina.Le ndlela yokuhlola engacekeli phansi inikeza impendulo ebalulekile ekubukekeni kwe-weld iyonke futhi ingabonisa ukuba khona kokukhubazeka okungenzeka.
2. Amasu Okuhlola Okungabhubhi (NDT): a.Ukuhlolwa kwe-Ultrasonic (UT): I-UT isebenzisa amaza omsindo we-high-frequency ukuze ihlole amashisela ukuze ibone ukukhubazeka kwangaphakathi.Ingakwazi ukubona ukungaqhubeki, njengokuqhekeka noma ukuntuleka kokuhlangana, ngaphakathi kwejoyinti le-weld ngaphandle kokudala umonakalo engxenyeni.I-UT iwusizo ikakhulukazi ekutholeni amaphutha afihliwe kuma-welds abalulekile.

b.Ukuhlolwa kwe-Radiographic (RT): I-RT ihlanganisa ukusetshenziswa kwama-X-reyi noma imisebe ye-gamma ukuze kutholwe izithombe zesakhiwo sangaphakathi sejoyinti le-weld.Le nqubo ivumela abahloli ukuthi babone ukukhubazeka kwangaphakathi, i-voids, nokufaka okungenzeka kungabonakali ngesikhathi sokuhlolwa okubonakalayo.

c.I-Magnetic Particle Testing (MT): I-MT isetshenziswa ngokuyinhloko ukuhlola izinto ze-ferromagnetic.Kubandakanya ukusebenzisa amandla kazibuthe kanye nezinhlayiya kazibuthe endaweni yokushisela.Izinhlayiya zizonqwabelana ezindaweni ezinokukhubazeka, okuzenza zibonakale kalula.

d.Ukuhlolwa kwe-Liquid Penetrant Testing (PT): I-PT isetshenziswa ukukhomba amaphutha aphuka phezulu ezintweni ezingezona izimbotshana.Uketshezi olungena ngaphakathi lusetshenziswa endaweni yokushisela, bese kuthi ukungena okweqile kuyasulwa.I-penetrant esele ibe isivezwa ngokusetshenziswa komthuthukisi, okugqamisa noma yikuphi ukonakala kwendawo.

3. Ukuhlola Okulimazayo (i-DT): Ezimeni lapho ikhwalithi ye-weld kufanele ihlolwe ngokuqinile, izindlela zokuhlola ezilimazayo ziyasetshenziswa.Lezi zivivinyo zibandakanya ukukhipha ingxenye yejoyinti le-weld ukuze kuhlolwe izakhiwo namandla ayo okusebenza.Izindlela ezijwayelekile ze-DT zifaka: a.Ukuhlola I-Tensile: Ikala amandla okuqina kwejoyinti le-weld kanye ne-ductility.b.Ukuhlola Ukugoba: Ihlola ukumelana kwe-weld ekuqhekekeni noma ekuqhekekeni ngaphansi kwengcindezi yokugoba.c.Ukuhlola Okukhulu: Kuhilela ukuhlukanisa nokupholisha i-weld ukuze kuhlolwe ukwakheka kwayo kanye nokungena kwe-weld.

Ukwenza ukuhlolwa kwe-post-weld usebenzisa izindlela ezihlukahlukene kubalulekile ukuze kuqinisekiswe ukwethembeka kanye nekhwalithi yamajoyini we-weld adalwe umshini wokushisela we-nut spot.Inhlanganisela yokuhlola okubukwayo, amasu okuhlola angalimazi, futhi, uma kunesidingo, ukuhlola okulimazayo kunikeza imininingwane ebanzi ngobuqotho be-weld nokubambelela kumazinga omkhakha.Ngokusebenzisa lezi zindlela zokuhlola, ochwepheshe bokushisela bangaqinisekisa ukuphepha nokusebenza kwezingxenye ezishiselwe ezinhlelweni ezihlukahlukene.
