I-Resistance spot welding iyindlela esetshenziswa kakhulu embonini yokukhiqiza, esetshenziselwa ukuhlanganisa amashidi ensimbi ngokwakha amandla kagesi asendaweni endaweni yokushisela. Ukukhethwa kwezinto ze-electrode kudlala indima ebalulekile enqubweni yokushisela, kuthonya izici ezifana nekhwalithi yokushisela, ukuqina, kanye nokusebenza kahle kwezindleko.
1. Ama-Electrode Ethusi
Ama-electrode ethusi angenye yezinketho ezivame kakhulu zemishini yokushisela indawo yokumelana. Baziwa ngokusebenza kwabo okuhle kakhulu kwe-thermal kanye nogesi, okusiza ekukhiqizeni ukushisa okudingekayo kwe-welding. Ama-electrode ethusi nawo anikeza ukuqina okuhle futhi angamelana namazinga okushisa aphezulu. Kodwa-ke, zivame ukuguga ngokuhamba kwesikhathi futhi zingadinga ukushintshwa noma ukulungiswa njalo.
2. Ama-Tungsten Electrodes
Ama-electrode e-Tungsten angenye inketho yokushisela indawo yokumelana. Zinezinga eliphezulu lokuncibilika kanye ne-conductivity kagesi enhle kakhulu, okubenza bafanelekele izicelo zokushisela ezibandakanya ukushisa okuphezulu nokumelana nogesi. Ama-electrode e-Tungsten aziwa ngokuphila kwawo isikhathi eside, kodwa angabiza kakhulu ngaphambili uma kuqhathaniswa nama-electrode ethusi.
3. I-Refractory Metal Alloys
Ezinye izinhlelo zokusebenza zokushisela indawo yokumelana zidinga amaphuzu aphezulu ancibilikayo nokuqina kunalokho okunganikezwa yi-tungsten. Ezimweni ezinjalo, kusetshenziswa ama-alloys ensimbi aphikisayo njenge-molybdenum ne-tantalum. Lezi zinto zinikeza ukumelana okukhethekile nokushisa nokugqwala, okuzenza zilungele imisebenzi ekhethekile yokushisela. Kodwa-ke, izindleko zabo eziphezulu zingaba yisici esikhawulela izinhlelo zokusebenza ezibanzi.
4. Ama-Electrode Ahlanganisiwe
Ama-electrode ahlanganisiwe ahlanganisa izinto ezahlukene ukuze afinyelele ibhalansi yezakhiwo. Isibonelo, i-electrode ehlanganisiwe ye-copper-tungsten ihlanganisa ukuqhutshwa kwethusi okuhle kakhulu nokumelana nokushisa okuphezulu kwe-tungsten. Lawa ma-electrode anikeza ukuyekethisa phakathi kwezindleko nokusebenza, okwenza kube yisinqumo esithandwayo sezinhlelo zokusebenza eziningi zokushisela.
5. Electrode Coatings
Kwezinye izimo, ama-electrode ambozwa ngezinto ezifana ne-chromium noma i-zirconium ukuze athuthukise ukumelana kwawo nokuguga nokugqwala. Lezi zembatho zinganweba isikhathi sokuphila se-electrode futhi zithuthukise ikhwalithi ye-weld.
Sengiphetha, ukukhetha kwempahla ye-electrode yemishini yokushisela indawo yokumelana kuncike ezintweni ezahlukahlukene, kufaka phakathi uhlelo oluthile lokushisela, ukucatshangelwa kwezindleko, nezici zokusebenza ezifiswayo. Ithusi, i-tungsten, ama-alloys ensimbi aphikisayo, izinto eziyinhlanganisela, kanye nama-electrode coatings konke kunezinzuzo nokulinganiselwa kwakho. Onjiniyela kanye nabashisela kufanele bahlole ngokucophelela lezi zici ukuze bakhethe izinto ezifanele kakhulu ze-electrode ngezidingo zabo, ekugcineni baqinisekise impumelelo yenqubo yokushisela.
