Inqubo Yokwakhiwa Kwezindawo Zokushisela Emishinini Yokushisela I-Nut Spot

Emkhakheni wemishini yokushisela indawo yamantongomane, ukwakheka kwamabala okushisela kuyinqubo ebalulekile enquma amandla nokuthembeka kwelunga. Ukuqonda ubunkimbinkimbi bale nqubo yokwakheka kubalulekile ukuze kuzuzwe ukushiselwa kwekhwalithi ephezulu ezinhlelweni ezihlukahlukene. Lesi sihloko sicubungula inqubo yesinyathelo ngesinyathelo yokuthi amabala okushisela akhiwa kanjani emishinini yokushisela amantongomane.

1. Ukulungiselela Ubuso: Ngaphambi kokuqala inqubo yokushisela, ingaphezulu lezinto zokusebenza namantongomane kufanele kuhlanzwe kahle ukuze kukhishwe noma yikuphi ukungcola noma izendlalelo ze-oxide. Lokhu kuqinisekisa ukuthintana kwensimbi kuya kwensimbi, okubalulekile ukuze kuzuzwe ukuhlangana okuqinile nokuqinile.
2. I-Electrode Contact: Njengoba umshini wokushisela amantongomane usebenza, ama-electrode athintana ne-workpiece namantongomane. Ukusetshenziswa kwengcindezi kuvumela ukusungulwa koxhumano lukagesi futhi kuqala ukugeleza kwe-welding current.
3. I-Joule Heating: Ukugeleza kwe-welding current nge-electrode kanye ne-workpiece kukhiqiza ukushisa kwe-Joule lapho kuxhunywana khona. Lokhu kubangela ukuncibilika kwendawo kwensimbi kusixhumi esibonakalayo, kwakheka idamu lokushisela elincibilikisiwe.
4. Ukusabalalisa Ukushisa: Phakathi nenqubo yokushisela, ukusatshalaliswa kokushisa kudlala indima ebalulekile ekulawuleni usayizi nokujula kwendawo yokushisela. Ukusabalalisa ukushisa okufanele kuqinisekisa ukuthi insimbi encibilikisiwe ingena ezintweni zokusebenza kanye namantongomane ngokuphumelelayo, yakha isibopho esiqinile se-metallurgical.
5. Ukuqiniswa: Njengoba i-welding current inqamuka, insimbi encibilikisiwe iphola ngokushesha futhi iqine, ihlanganise ucezu lokusebenza namantongomane ndawonye. Inqubo yokuqinisa ithonya izici zemishini zendawo yokushisela, okuhlanganisa amandla ayo nobulukhuni.
6. I-Annealing Effect: Kwezinye izimo, indawo yokushisela ingase ibe nomthelela we-annealing, lapho indawo ethinteke ukushisa ilawula ukupholisa ukuze kudambise izingcindezi ezinsalela futhi kuthuthukiswe ukudungeka kwelunga.
7. Ukuhlolwa Kwekhwalithi: Ngemuva kwenqubo yokushisela, izindawo zokushisela zingaphansi kokuhlolwa okuqinile kwekhwalithi ukuze kuqinisekiswe ukuthotshelwa kokucaciswa okufiswayo namazinga. Kungase kusetshenziswe izindlela ezihlukahlukene zokuhlola ezingalimazi ukuze kuhlolwe ubuqotho be-weld.

Inqubo yokwakheka kwezindawo zokushisela emishinini yokushisela amantongomane iwukusebenzisana okuguquguqukayo kwamandla kagesi, ukukhiqiza ukushisa, nokuhlanganisa i-metallurgical. Ngokulungiswa ngokucophelela kwendawo, ukusetshenziswa okunembile kwe-welding current, kanye nokusabalalisa ukushisa okufanele, izindawo zokushisela ezisezingeni eliphezulu ziyafinyelelwa, okunomthelela emandleni kanye nokusebenza kwamajoyinti ashiselwe. Ukuqonda kanye nokwenza kahle le nqubo yokubunjwa kubaluleke kakhulu ekuqinisekiseni ukwethembeka nokuphila isikhathi eside kwezingxenye ezishiselwe ezinhlelweni ezihlukahlukene zezimboni.
