Zambiri Zokhudza Kuwotcherera Ma Electrodes

Zambiri Zokhudza Kuwotcherera Electrodes

Tianqiao welding electrode ndiye njira yaukadaulo

Ma elekitirodi owotcherera ndi ofunikira, ndipo ndikofunikira kuti wowotchera ndi ogwira nawo ntchito adziwe mtundu wanji woti agwiritse ntchito ntchito zosiyanasiyana.

Kodi ma elekitirodi owotcherera ndi chiyani?

Elekitirodi ndi waya wachitsulo wokutidwa, womwe umapangidwa ndi zinthu zofanana ndi zitsulo zomwe zimawotchedwa.Poyambira, pali ma electrode ogwiritsidwa ntchito komanso osagwiritsidwa ntchito.Mu chishango chachitsulo cha arc welding (SMAW) chomwe chimatchedwanso ndodo, ma electrode amatha kudyedwa, zomwe zikutanthauza kuti electrode imagwiritsidwa ntchito panthawi yomwe imagwiritsidwa ntchito ndikusungunuka ndi weld.Mu Tungsten Inert Gas welding (TIG) maelekitirodi satha kudyedwa, kotero samasungunuka ndikukhala gawo la weld.Ndi Gas Metal Arc Welding (GMAW) kapena kuwotcherera kwa MIG, ma elekitirodi amadyetsedwa mawaya mosalekeza.2 Flux-cored arc welding imafuna kudyetsedwa kosalekeza kwa tubular electrode yokhala ndi flux.

Kodi kusankha maelekitirodi kuwotcherera?

Kusankha electrode kumatsimikiziridwa ndi zofunikira za ntchito yowotcherera.Izi zikuphatikizapo:

  • Kulimba kwamakokedwe
  • Ductility
  • Kukana dzimbiri
  • Chitsulo choyambira
  • Weld udindo
  • Polarity
  • Panopa

Pali maelekitirodi opepuka komanso olemera.Maelekitirodi opaka kuwala amakhala ndi zokutira zopepuka zomwe zimagwiritsidwa ntchito popaka, kupopera mbewu mankhwalawa, kumiza, kuchapa, kupukuta, kapena kugwa.Ma electrodes olemera kwambiri amakutidwa ndi extrusion kapena kudontha.Pali mitundu itatu ikuluikulu ya zokutira zolemera: mineral, cellulose, kapena kuphatikiza ziwirizi.Zovala zolemera zimagwiritsidwa ntchito powotcherera chitsulo, zitsulo, ndi malo olimba.

Kodi manambala ndi zilembo zimatanthauza chiyani pa ndodo zowotcherera?

Bungwe la American Welding Society (AWS) lili ndi makina owerengera omwe amapereka zambiri za electrode inayake, monga momwe imagwiritsidwira ntchito bwino komanso momwe iyenera kugwiritsidwira ntchito kuti ikhale yogwira mtima kwambiri.

Kudziwa mitundu yosiyanasiyana ya maelekitirodi ndi kugwiritsa ntchito kwawo kumathandiza kuti ntchito yowotcherera igwire bwino.Kuganizira kumaphatikizapo njira yowotcherera, zida zowotcherera, momwe zilili m'nyumba / kunja, ndi malo owotcherera.Kuyeserera ndi mfuti zowotcherera ndi maelekitirodi kungakuthandizeni kudziwa kuti ndi ma elekitirodi ati omwe mungagwiritse ntchito powotcherera.
