Zinthu Zazonse Zokhudza kuwotcherera ma elekitirodi

Zinthu Zambiri Zokhudza Kutulutsa Ma Electrode

Tianqiao kuwotcherera elekitirodi ndi njira akatswiri

Ma elekitirodi owotcherera ndi ofunikira, ndipo nkofunikira kuti wowotcherera komanso wogwira ntchito azidziwa mtundu womwe angagwiritse ntchito zosiyanasiyana.

Kodi kuwotcherera maelekitirodi ndi chiyani?

Elekitirodi ndi waya wachitsulo wokutira, womwe umapangidwa ndi zinthu zofananira ndi chitsulo chomwe chimalumikizidwa. Pongoyambira, pali maelekitirodi ogwiritsira ntchito komanso osagwiritsika ntchito. Pachitetezo chachitsulo cha arc welding (SMAW) chomwe chimadziwikanso kuti ndodo, maelekitirodi ndiomwe angathe kugwiritsidwa ntchito, zomwe zikutanthauza kuti maelekitirodi amadyedwa akagwiritsidwa ntchito ndikusungunuka ndi weld. Mu ma elekitirodi a Tungsten Inert Gas welding (TIG) ndiosagwiritsika ntchito, chifukwa chake samasungunuka ndikukhala gawo la weld. Ndi Gasi Chitsulo Arc kuwotcherera (GMAW) kapena MIG kuwotcherera, maelekitirodi ali mosalekeza kudyetsedwa waya. 2 Flux-cored arc kuwotcherera kumafunikira mosalekeza kudyetsa ma tubular elekitirodi okhala ndi kutuluka.

Kodi kusankha maelekitirodi kuwotcherera?

Kusankha elekitirodi kumatsimikiziridwa ndi zofunikira za ntchito yowotcherera. Izi zikuphatikiza:

  • Kulimba kwamakokedwe
  • Ductility
  • Dzimbiri kukana
  • Zitsulo zoyambira
  • Weld udindo
  • Polarity
  • Zamakono

Pali maelekitirodi opepuka komanso olemera. Maelekitirodi okutira owala amakhala ndi zokutira zowunikira zomwe zimagwiritsidwa ntchito kutsuka, kupopera, kumiza, kutsuka, kupukuta, kapena kugwa. Maelekitirodi olemera amakutidwa ndi extrusion kapena kutuluka. Pali mitundu itatu yayikulu yokutira yolemera: mchere, mapadi, kapena kuphatikiza kwake. Zokutira zolemera zimagwiritsidwa ntchito popangira chitsulo chosungunula, zitsulo, ndi malo olimba.

Kodi manambala ndi zilembo zimatanthauza chiyani pa ndodo zowotcherera?

American Welding Society (AWS) ili ndi makina owerengera omwe amapereka chidziwitso chokhudza ma elekitirodi ena, monga momwe amagwiritsidwira ntchito moyenera komanso momwe angagwiritsire ntchito moyenera.

Manambala Mtundu wokutira Kuwotcherera Current
0 Mkulu mapadi ndi sodium DC +
1 Mapuloteni apamwamba potaziyamu AC, DC + kapena DC-
2 Mkulu titania sodium AC, DC-
3 Mkulu wa titania potaziyamu AC, DC +
4 Iron ufa, titania AC, DC + kapena DC-
5 Sodium wa hydrogen wotsika DC +
6 Potaziyamu wotsika wa hydrogen AC, DC +
7 Mkulu chitsulo okusayidi, potaziyamu ufa AC, DC + kapena DC-
8 Low potaziyamu potaziyamu, chitsulo ufa AC, DC + kapena DC-

"E" ikuwonetsa maelekitirodi a arc. Manambala awiri oyamba a manambala a 4 ndi manambala atatu oyamba a manambala asanu amaimira mphamvu yolimba. Mwachitsanzo, E6010 amatanthauza mapaundi 60,000 pa mphamvu yolimba ya mainchesi (PSI) ndipo E10018 amatanthauza mphamvu ya psi 100,000. Chotsatira cha manambala omaliza chikuwonetsa malo. Chifukwa chake, "1" imayimira ma elekitirodi onse, "2" pamaelekedwe opyapyala komanso osasunthika, ndi "4" pamaeleketi opindika, opingasa, owongoka pansi ndi pamwamba. Manambala awiri omaliza mwachindunji mtundu wa of kuyanika ndi panopa kuwotcherera. 4

Kudziwa mitundu yamaelekitirodi osiyanasiyana ndi momwe amagwiritsidwira ntchito ndizothandiza kugwira ntchito yowotcherera molondola. Zomwe mungaganizire zimaphatikizira njira zowotcherera, zopangira zotsekemera, zamkati / zakunja, ndi malo otsekemera. Kuyeserera ndi mfuti zingapo zamagetsi ndi maelekitirodi kungakuthandizeni kudziwa ma elekitirodi omwe mungagwiritse ntchito pomanga polojekiti.
