Welding electrodes iwaya dzesimbi dzakabikwa pamachira emakemikari.Tsvimbo inoshandiswa kuchengetedza welding arc uye kupa simbi yekuzadza inodiwa kuti mubatanidzwa ugosungwa.Iyo yekuputira inodzivirira simbi kubva mukukuvadzwa, inodzikamisa arc, uye inovandudza weld.Iyo dhayamita yewaya, zvishoma kupfekedza, inosarudza ukuru hwetsvimbo yewelding.Izvi zvinoratidzwa muzvikamu zve inch senge 3/32 ″, 1/8 ″, kana 5/32.Iyo diki dhayamita inoreva kuti inoda kushoma ikozvino uye inoisa diki diki rekuzadza simbi.
Rudzi rwesimbi yepasi iri kugadzirwa, iyo welding process uye muchina, uye mamwe mamiriro anosarudza mhando yewelding electrode inoshandiswa.Semuenzaniso, low carbon kana "mild steel" inoda simbi yakapfava welding tsvimbo.Welding cast iron, aruminiyamu kana ndarira inoda akasiyana welding tsvimbo nemidziyo.
Iyo flux coating pama electrode inosarudza kuti ichaita sei panguva chaiyo welding process.Zvimwe zvekuputira zvinopisa uye kubuda kunopisa kunoumba utsi uye kunoshanda senhovo yakakomberedza "dziva" rekuputira, kuti ridzivirire kubva kumhepo yakaipoteredza.Chikamu chezvinoyerera chinonyunguduka uye chinosanganiswa newaya chobva chayangarara tsvina yacho pamusoro.Iyi tsvina inozivikanwa se "slag."Weld yakapedzwa yaizova brittle uye isina simba kana isiri yekuyerera.Apo iyo welded joint inotonhorera, slag inogona kubviswa.Sando yekuchekesa uye bhurasho rewaya zvinoshandiswa kuchenesa uye kuongorora weld.
Metal-arc welding electrodes inogona kuiswa mumapoka sema electrode asina chinhu, light coated electrodes, uye shielded arc kana heavy coated electrodes.Rudzi runoshandiswa runotsamira pane chaiyo midziyo inodiwa iyo inosanganisira: corrosion resistance, ductility, high tensile simba, rudzi rwesimbi yepasi inofanira kuiswa welded;uye nzvimbo yeweld yakati sandara, yakachinjika, yakatwasuka, kana pamusoro.
