Xa kufikwa kwi-stainless steel welding, ukukhetha i-electrode kudlala indima ebalulekileyo ekumiseleni umgangatho kunye nokuqina kwe-weld. Phakathi kweendlela ezininzi ezithengiswayo, i-A412iintonga zokuweldaIgqame njengokhetho lokuqala phakathi kweengcali kunye nabantu abathanda izinto zokuzonwabisa. I-A412 yi-electrode yentsimbi engagqwaliyo ye-Cr26Ni21Mo2 ecocekileyo ene-calcium titanium coating ebonelela ngokusebenza okugqwesileyo kunye nokuguquguquka kwiintlobo ngeentlobo zezicelo zokuwelda.
Yenzelwe ukubonelela ngeziphumo ezigqwesileyo xa usebenza ngentsimbi engagqwaliyo, ii-electrode ze-A412 zibonelela ngokusebenza okugqwesileyo kokuwelda kwe-AC kunye ne-DC. Ulwakhiwo lwayo olukhethekileyo, kubandakanya ukongezwa kwe-molybdenum kwisinyithi esigciniweyo, kwandisa ukumelana kwayo nokugqwala, amandla obushushu kunye nokuqhekeka xa kuthelekiswa nezinye iindlela ze-electrode ezifana ne-A402 kunye ne-A407. Oku kwenza i-A412 ibe lukhetho lokuqala kwiiprojekthi zokuwelda ezifuna amandla aphezulu kunye nokuqina.
Enye yezona nzuzo ziphambili zee-electrode ze-A412 kukukwazi kwazo ukubonelela ngeziphumo ezithembekileyo nezihambelanayo kwiindlela ezahlukeneyo zokufaka ii-welding. Nokuba usebenza kwizinto zokwakha, oomatshini okanye ukwenziwa kwentsimbi engagqwaliyo, ii-electrode ze-A412 zibonelela ngokuchaneka nokuthembeka okudingayo kwii-welds ezikumgangatho ophezulu. I-titanium-calcium coating iphucula ngakumbi uzinzo lwe-arc kunye nokwahlulwa kwe-slag, iqinisekisa ii-welds ezigudileyo nezicocekileyo ezingenamanzi amaninzi.
A412iintonga zokuweldazaziwa ngokulula kokusetyenziswa kwazo kunye nokuguquguquka kwazo. Ezi electrode zingasetyenziswa kunye noomatshini bokuwelda be-AC kunye ne-DC, zibonelela ngokuguquguquka kunye nokulula kubawelda kwiindawo ezahlukeneyo. Nokuba ungumwelda onamava okanye ungumwelda osaqalayo, i-A412iintonga zokuweldaukubonelela ngamava alula ukuyisebenzisa akuvumela ukuba ugxile kumsebenzi okhoyo ngaphandle kokubeka emngciphekweni umgangatho we-weld.
Ii-electrode ze-A412 zimele isisombululo esiphezulu sokuwelda ngentsimbi engagqwaliyo, zibonelela ngokusebenza okungenakuthelekiswa nanto, ukuqina kunye nokuguquguquka. Ngokwakhiwa kwayo okwahlukileyo kunye nokufakwa kwe-calcium titanium, ii-electrode ze-A412 zenzelwe ukuhlangabezana neemfuno zezicelo zokuwelda zanamhlanje, zibonelela ngeziphumo ezigqwesileyo kwiiprojekthi ezahlukeneyo zokuwelda. Nokuba usebenza kwimisebenzi yokuwelda yemizi-mveliso, yezorhwebo okanye yezindlu, ii-electrode ze-A412 zibonelela ngokuthembeka kunye nokuchaneka okufunekayo kwii-welds ezisemgangathweni, okwenza zibe yinto ebalulekileyo kuyo nayiphi na ingcali yokuwelda okanye umthandi.
