Ungakhetha kanjani impahla ye-electrode yomshini wokushisela we-medium frequency spot? Spot welding electrode ikhanda ngokusebenzisa yamanje yezinkulungwane kuya emashumini ezinkulungwane amperes, ukumelana voltage 9.81~49.1MPa, izinga lokushisa kweso 600℃~900℃. Ngakho-ke, i-electrode iyadingeka ukuze ibe ne-conductivity enhle kagesi, ukuqhutshwa kokushisa okushisayo, ubulukhuni bokushisa nokumelana nokugqwala okuphezulu.
Ama-electrode welding we-spot enziwe ngama-alloys ethusi. Ukuze kuthuthukiswe ukusebenza kwama-electrode e-alloy yethusi, ngokuvamile kudingekile ukuba kwenziwe ukwelashwa okuqiniswayo, okufana nalokhu: ukuqinisa ukucubungula okubandayo, ukuqinisa isisombululo esiqinile, ukuqinisa imvula yokuguga nokuqinisa ukuhlakazeka. Ukusebenza kwe-electrode nakho kuyashintsha ngemva kokwelashwa okuhlukile kokuqinisa. Lapho amapuleti ensimbi abandayo, amapuleti ensimbi, insimbi engagqwali noma amapuleti e-aluminium kudingeka ashiselwe amabala, izinto ezifanele ze-electrode kufanele zikhethwe ngokuya ngezakhiwo zezinto zamapuleti.
Ukukhethwa kwezinto zokwenziwa kwe-electrode zokushisela ipuleti lensimbi elinothayela kufanele kunciphise ibala kanye nokuwohloka kwe-electrode ngesikhathi sokushisela, okudinga ubulukhuni obuphezulu, ukuhanjiswa okuhle kukagesi nokushisayo kwe-electrode ezingeni lokushisa eliphezulu, kanye nokuthambekela okuncane kwe-alloying nge-zinc.
Impilo ye-electrode yokushisela ipuleti lensimbi enama-electrode amaningana yinde kune-cadmium copper electrode. Ngoba nakuba i-conductivity kagesi neyokushisa ye-cadmium yethusi ingcono, ngokuvamile kukholelwa ukuthi ukunamathela kwe-zinc kuncane, kodwa empeleni, ngenxa yokushisa kwayo okuphansi kokuthambisa, umthelela wokuqina kokushisa okuphezulu mkhulu. Ukuqina kokushisa okuphezulu kwe-zirconium yethusi kuphakeme, ngakho-ke impilo yayo nayo yinde. Nakuba ubulukhuni bokushisa obuphezulu be-beryllium diamond yethusi buphakeme, ngenxa yokuthi ukuqhutshwa kwayo kubi kakhulu kunethusi le-chromium-zirconium, i-conductivity kanye ne-thermal conductivity idlala indima enkulu ethonyeni lokuphila kwayo, futhi impilo yayo ye-electrode iphansi kakhulu.
Ngaphezu kwalokho, ukusetshenziswa kwe-tungsten (noma i-molybdenum) ehlanganisiwe ye-electrode welding galvanized steel plate, impilo yayo nayo iphakeme, nakuba i-conductivity ye-tungsten, i-molybdenum iphansi, kuphela i-1/3 yethusi ye-chromium, kodwa izinga lokushisa layo elithambile liphezulu. (1273K), izinga lokushisa eliphezulu ubulukhuni (ikakhulukazi tungsten), electrode akulula deformation.
