Ukuphuka kwendawo yokushisela kungaba yinkinga enzima okuhlangatshezwane nayo ngesikhathi sokusebenza kwemishini yokushisela amabala amantongomane. Ubuqotho bejoyinti le-weld busengozini lapho izindawo zokushisela zihluleka ukumelana nemithwalo efakiwe noma izingcindezi zemvelo. Kulesi sihloko, sizohlola izimbangela ezivamile zokuphuka kwendawo ye-weld futhi sethule izixazululo ezisebenzayo zokubhekana nale nkinga.
- Izimbangela ze-Weld Spot Fracture:
- Ukungena Kwe-Weld Okwanele: Ukufakwa kokushisa okunganele noma ukucindezela okunganele ngesikhathi sokushisela kungaholela ekuhlanganiseni okungaphelele, okuholela emazingeni e-weld abuthakathaka ajwayele ukuphuka.
- Ukungahambelani Kwezinto Ezibalulekile: Izinto ezingafani nama-coefficients ahlukene wokunweba okushisayo zingabangela ukugxila kwengcindezi futhi zikhuthaze ukuphuka kusixhumi esibonakalayo se-weld.
- Ukungcoliswa kwe-Electrode: Ama-electrode angcolile angase ethule ukungcola endaweni yokushisela, enze buthaka izici zemishini zelunga futhi kuholele ekuhlulekeni ngaphambi kwesikhathi.
- Usayizi we-Weld Spot kanye Nomumo: Ijiyomethri yendawo yokushisela engafanele, njengobubanzi obudlulele noma umumo ongajwayelekile, ingabangela amaphuzu okugxilisa ingqondo futhi ikhuthaze ukuqaliswa kokuphuka.
- Amapharamitha Welding Athuthukisiwe: Ukuthuthukisa amapharamitha wokushisela kubalulekile ukubhekana nokuphuka kwendawo yokushisela. Ukwandisa i-welding current, ingcindezi ye-electrode, nesikhathi sokushisela kungathuthukisa ukungena kwe-weld kanye nokuhlanganisa, okuholela ezindaweni eziqinile zokushisela.
- Ukukhethwa Kwezinto Ezibalulekile: Ukukhetha izinto ezihambisanayo ezinezakhiwo ezifanayo zemishini kanye nama-coefficients okwandisa okushisayo kunganciphisa ukugxila kwengcindezi futhi kuthuthukise ubuqotho obuhlangene be-weld.
- Ukugcinwa Kwe-Electrode Nokuhlanza: Ukugcinwa njalo nokuhlanza ama-electrode kubalulekile ukuze kuvinjwe ukungcoliswa ngesikhathi sokushisela. Ukunakekelwa okufanele kwe-electrode kuqinisekisa ukwakheka okungaguquguquki futhi okuphezulu kwe-weld spot.
- Idizayini ye-Weld Spot Nokuhlola: Idizayini efanele yezindawo zokushisela, okuhlanganisa usayizi nokuma, kungasiza ukusabalalisa ingcindezi ngokulinganayo futhi kunciphise ingozi yokuphuka. Ukwengeza, ukuhlola okuvamile nokuhlola okungalimazi kungathola amaphutha angenzeka kusenesikhathi, okuvumela izenzo zokulungisa ngesikhathi.
- Ukwelashwa kwe-Annealing kanye ne-Post-Weld: Ukufaka imishanguzo ye-annealing noma ye-post-weld kungasiza ekudambiseni izingcindezi ezinsalela kujoyinti le-weld, kuthuthukise ukudubeka kwalo kanye nokumelana nokuphuka.
Ukuvimbela ukuphuka kwendawo yokushisela emishinini yokushisela amantongomane kudinga indlela ebanzi ehlanganisa ukwenza kahle imingcele yokushisela, ukukhetha izinto ezihambisanayo, ukugcinwa kwama-electrode, nokusebenzisa izinyathelo ezisebenzayo zokulawula ikhwalithi. Ngokubhekana nezimbangela eziyinhloko zokuphuka kwe-weld spot, abakhiqizi bangaqinisekisa ukukhiqizwa kwamajoyinti e-weld aqinile futhi athembekile, okunomthelela ekusebenzeni okuphelele nokuphepha kwezingxenye ezishiselwe ezimbonini ezihlukahlukene.
