Unokukhetha njani izinto ze-electrode zomatshini we-welding we-medium frequency spot? Intloko ye-electrode ye-Spot welding ngokusebenzisa langoku lamawaka ukuya kumashumi amawaka e-amperes, ukumelana nombane we-9.81 ~ 49.1MPa, ubushushu bethutyana obuyi-600℃~900℃. Ngoko ke, i-electrode iyadingeka ukuba ibe ne-conductivity elungileyo yombane, i-thermal conductivity, i-thermal hardness kunye ne-high corrosion resistance.

I-electrodes ye-welding ye-spot yenziwe ngee-alloys zobhedu. Ukuze kuphuculwe ukusebenza kwee-electrode ze-alloy copper, ngokuqhelekileyo kuyimfuneko ukuba ufumane unyango olomelezayo, olufana nokuqiniswa kwenkqubo ebandayo, ukomeleza isisombululo esiqinileyo, ukomeleza ukuguga kunye nokuqiniswa kokusasazwa. Ukusebenza kwe-electrode kwakhona kuyatshintsha emva konyango olulomelezayo olwahlukileyo. Xa iipleyiti zetsimbi ezibandayo, iipleyiti zetsimbi, insimbi engenasici okanye iiplati ze-aluminium kufuneka zibe ne-spot-welded, izinto ezifanelekileyo ze-electrode kufuneka zikhethwe ngokweempawu zeplate.

Ukukhethwa kwezixhobo ze-electrode ukwenzela ukuwelda ipleyiti yentsimbi ekhandisiweyo kufuneka kuncitshiswe ibala kunye nokuguqulwa kwe-electrode ngexesha lokuwelda, efuna ubulukhuni obuphezulu, umbane olungileyo kunye ne-thermal conductivity ye-electrode kubushushu obuphezulu, kunye ne-alloying tyency encinci ene-zinc.

Ubomi be-electrode ye-galvanized steel plate welding kunye nezixhobo ezininzi ze-electrode ubude kunobo be-cadmium copper electrode. Kuba nangona umbane kunye ne-thermal conductivity ye-cadmium yethusi ingcono, kukholelwa ngokubanzi ukuba ukunamathela kwe-zinc kuncinci, kodwa eneneni, ngenxa yobushushu obuphantsi bokuthambisa, impembelelo yokuqina kobushushu obuphezulu bukhulu. Ubulukhuni beqondo lokushisa eliphezulu le-zirconium yobhedu buphezulu, ngoko ke ubomi bayo bude. Nangona ubushushu obuphezulu be-beryllium yobhedu yedayimani buphezulu, ngenxa yokuba ukuhanjiswa kwayo kubi kakhulu kunobhedu lwe-chromium-zirconium, i-conductivity kunye ne-thermal conductivity idlala indima enkulu kwimpembelelo yobomi bayo, kwaye ubomi bayo be-electrode buphantsi.

Ukongeza, ukusetyenziswa kwe-tungsten (okanye i-molybdenum) efakwe kwi-electrode edibeneyo ye-welding yensimbi yentsimbi, ubomi bayo buphezulu, nangona i-tungsten conductivity, i-molybdenum iphantsi, kuphela malunga ne-1/3 yobhedu lwe-chromium, kodwa ubushushu bayo bokuthambisa buphezulu. (1273K), ubunzima obuphezulu beqondo lokushisa (ingakumbi i-tungsten), i-electrode ayilula ukuyiguqula.
