I-Spot welding iyinqubo yokujoyina esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi ezezimoto nezokukhiqiza. Ku-medium-frequency inverter spot welding, ikhwalithi ye-weld nokusebenza kuthintwa izici ezihlukahlukene, kuhlanganise nengcindezi. Lesi sihloko sihlose ukuhlola umthelela wengcindezi ekushiseleni kwendawo ekushiseleleni indawo ye-medium-frequency inverter spot.
- Imithelela yeStress kuma-Spot Welds: Ukucindezeleka kungaba nemiphumela emihle nemibi ekushiseleni kwendawo. Ukuqonda le miphumela kubalulekile ekuthuthukiseni inqubo yokushisela kanye nokuqinisekisa ubuqotho bamalunga e-weld. Imithelela eyinhloko ye-stress kuma-spot welds ihlanganisa:
a. Amandla Ahlangene: Ukusatshalaliswa kokucindezeleka okufanele kuma-welds angathuthukisa amandla ahlangene. Uma ingcindezi isatshalaliswa ngokulinganayo endaweni yokushisela, ithuthukisa ukuhlangana kwe-interatomic futhi ikhuphule umthamo wokuthwala umthwalo we-weld. Lokhu kubangela ukujoyina okuqinile futhi okuthembekile.
b. I-Residual Stress: Ngesikhathi senqubo yokushisela, ukushisisa okusheshayo nokupholisa kubangela ukwanda nokuncipha kokushisa, okuholela ekucindezelekeni okusalayo ekushiseleni kwendawo. Ukucindezeleka okweqile kwensalela kungathinta izakhiwo zemishini ye-weld, njengokunciphisa impilo yayo yokukhathala nokwandisa ingozi yokuqhekeka noma ukuhlanekezela.
c. Ukugxila Kwengcindezi: Ukusatshalaliswa kwengcindezi okungafanele noma amaphutha edizayini kungaholela ekugxilweni kwengcindezi ezindaweni ezithile ngaphakathi kokushisela. Lokhu kugxiliswa kwengcindezi yendawo kungenza buthaka ukushisela futhi kukwenze kube lula ukwehluleka ngaphansi kwemithwalo esetshenzisiwe.
d. Ukuhlanekezela: Ukuhlanekezela okubangelwa ingcindezi kuyinkinga evamile ekushiseleni indawo. Ukusatshalaliswa kwengcindezi ye-asymmetric ngesikhathi sokushisela kungabangela izinto zokusebenza ukuthi ziwohloke noma zisonte, kuthinte ukunemba kobukhulu kanye nokulingana komkhiqizo wokugcina.
- Ukulawula Ingcindezi Ku-Spot Welding: Ukunciphisa imiphumela emibi yengcindezi nokuqinisekisa ukushiselwa kwamabala okuphezulu, amasu amaningana angasetshenziswa:
a. Amapharamitha Afanele Welding: Ukuthuthukisa imingcele yokushisela, njengamanje, isikhathi, namandla e-electrode, kungasiza ekufinyeleleni ukusabalalisa kokucindezeleka okulinganiselwe. Ngokukhetha ngokucophelela nokulawula le mingcele, ama-welders anganciphisa ukucindezeleka okusele futhi athuthukise amandla e-weld.
b. Idizayini Ehlanganyelwe: Ihlangano eklanywe kahle enejiyomethri efanele kanye nokuqinisa kungasiza ukusabalalisa ingcindezi ngokulinganayo endaweni yokushisela. Lokhu kunciphisa ukugxila kwengcindezi futhi kuthuthukisa ubuqotho obuphelele be-weld.
c. Ukwelashwa Kokushisa Kwangaphambi Nangemuva Nangemuva: Ukusebenzisa amasu okwelapha ukushisa kwangaphambi nangemuva kwe-weld, okufana nokunciphisa ingcindezi, kungasiza ekwehliseni ukucindezeleka okuyinsalela futhi kuthuthukise izici zemishini zokushisela kwendawo.
d. Ukuhlaziywa Kwesakhiwo: Ukwenza ukuhlaziya kwesakhiwo, njengokuhlaziya izinto ezinomkhawulo, kunganikeza imininingwane ekusabalaleni kwengcindezi futhi kusize ukukhomba izindawo zokugxilisa ingqondo ezingaba khona. Lokhu kuvumela onjiniyela ukuthi benze izinguquko zedizayini futhi balungiselele amapharamitha wokushisela ngokufanele.
Ukucindezeleka kuthinta kakhulu ukusebenza kanye nekhwalithi yama-spot welds ekushiseleleni indawo ye-medium-frequency inverter spot. Ngokuqonda imiphumela yengcindezi nokusebenzisa amasu okushisela afanelekile, ukucatshangelwa kwedizayini ehlanganyelwe, namasu okulawula ingcindezi, abashiseli nonjiniyela bangakwazi ukuthuthukisa ukushisela kwamabala ukuze kuthuthukiswe amandla, ukuqina, kanye nokunemba kobukhulu. Ukulawulwa kwengcindezi okusebenzayo ekugcineni kuholela ekushiseleni okuthembekile nokusezingeni eliphezulu okuhlangabezana nezidingo zezinhlelo zokusebenza ezahlukahlukene.
