General zvinhu Nezve Welding Electrodes
Tianqiao welding electrode ndiyo inyanzvi sarudzo
Welding electrodes yakakosha, uye zvakakosha kuti welder nevashandi vakakodzera vazive rudzi rwekushandisa kumabasa akasiyana.
Chii chinonzi welding electrodes?
Elekitirodhi iwaya yesimbi yakavharwa, iyo inogadzirwa nezvinhu zvakafanana nesimbi iri kurohwa.Kutanga, kune ma electrode anodyiwa uye asingashandisi.Munhovo yesimbi arc welding (SMAW) inozivikanwawo setsvimbo, ma electrodes anodyiwa, zvinoreva kuti electrode inopedzwa panguva yekushandiswa kwayo uye inonyunguduka ne weld.MuTungsten Inert Gas welding (TIG) maelectrodes haabatike, saka haanyungudike uye kuva chikamu cheweld.NeGas Metal Arc Welding (GMAW) kana MIG welding, maelectrodes anogara achipihwa waya.2 Flux-cored arc welding inoda kuramba ichidyiswa tubular electrode ine flux.
Ungasarudza sei welding electrodes?
Kusarudza electrode kunotarirwa nezvinodiwa zvebasa rekushongedza.Izvi zvinosanganisira:
- Kusimba simba
- Ductility
- Corrosion resistance
- Nheyo yesimbi
- Weld chinzvimbo
- Polarity
- Current
Kune chiedza uye chinorema coated electrodes.Maelectrode akavharwa nemwenje ane jira rakareruka rinoiswa kuburikidza nekukwesha, kupfapfaidza, kunyura, kuwacha, kupukuta, kana kudonha.Heavy coated electrodes akaputirwa ne extrusion kana kudonha.Kune marudzi matatu makuru emachira anorema: mineral, cellulose, kana musanganiswa weaya maviri.Heavy coatings anoshandiswa kugadzira simbi yakakandwa, simbi, uye nzvimbo dzakaoma.
Ko nhamba nemabhii zvinorevei pane welding rods?
IAmerican Welding Society (AWS) ine manhamba sisitimu inopa ruzivo nezve chaiyo electrode, sekuti iapplication yainonyanya kushandiswa uye mashandisirwo ainofanirwa kuitwa kuti inyatsoshanda.

Iyo "E" inoratidza arc welding electrode.Madijiti maviri ekutanga enhamba ine manhamba uye matatu ekutanga enhamba yenhamba 5 inomiririra simba rekusimba.Semuenzaniso, E6010 zvinoreva 60,000 pounds per square inch (PSI) tensile simba uye E10018 zvinoreva 100,000 psi tensile simba.Dijiti inotevera kune yekupedzisira inoratidza nzvimbo.Saka, "1" inomirira electrode yenzvimbo yese, "2" ye electrode yakatsetseka uye yakachinjika, uye "4" yemagetsi akati sandara, akatwasuka, akatwasuka pasi uye pamusoro.Nhamba mbiri dzekupedzisira dzinotsanangura rudzi rwekupfeka uye welding ikozvino.4

Kuziva marudzi akasiyana-siyana emagetsi uye mashandisirwo awo anobatsira kuita basa rekushongedza nemazvo.Mafungiro anosanganisira welding nzira, welding zvinhu, mukati / kunze mamiriro, uye welding zvinzvimbo.Kudzidzira nepfuti dzakasiyana-siyana dzekushongedza uye maelectrode zvinogona kukubatsira kuona kuti ndeipi electrode yekushandisa kune iyo welding chirongwa.
