Nā mea nui e pili ana i nā uila uila
ʻO Tianqiao welding electrode ke koho ʻoihana
He mea nui ka welding electrodes, a he mea nui e ʻike ka welder a me nā limahana kūpono i ke ʻano e hoʻohana ai no nā hana like ʻole.
He aha nā electrodes welding?
ʻO ka electrode kahi uea metala i uhi ʻia, i hana ʻia me nā mea like me ka metala i welded ʻia.No nā mea hoʻomaka, aia nā electrodes consumable a me nā mea ʻole.Ma ka pale metala arc welding (SMAW) i ʻike ʻia he lāʻau, hiki ke hoʻopau ʻia nā electrodes, ʻo ia hoʻi, pau ka electrode i kona hoʻohana ʻana a heheʻe me ka weld.Ma Tungsten Inert Gas welding (TIG) electrodes mea ole-consumable, no laila, aole lakou e hehee a lilo i wahi o ka weld.Me Gas Metal Arc Welding (GMAW) a i ʻole MIG welding, hoʻomau mau ʻia nā electrodes i ka uea.2 ʻO ka wiliwili arc-cored arc e pono ai i kahi electrode tubular consumable hoʻomau i loaʻa i kahi flux.
Pehea e koho ai i nā electrodes welding?
Hoʻoholo ʻia ke koho ʻana i kahi electrode e nā koi o ka hana welding.Aia kēia mau mea:
- Ka ikaika tensile
- ʻO ka ductility
- ʻO ke kūpaʻa ʻino
- Metala kumu
- Kūlana Weld
- Polarity
- ʻO kēia manawa
Aia nā electrodes i uhi ʻia maʻalahi a kaumaha.Loaʻa i nā electrodes i uhi ʻia me ka māmā i hoʻohana ʻia ma o ka hoʻomaʻamaʻa ʻana, ka pīpī ʻana, ke kuʻi ʻana, ka holoi ʻana, ka holoi ʻana, a i ʻole ka hina.Hoʻopili ʻia nā electrodes i uhi ʻia e ka extrusion a i ʻole ka kulu.ʻEkolu mau ʻano nui o ka uhi kaumaha: mineral, cellulose, a i ʻole ka hui pū ʻana o ia mau mea ʻelua.Hoʻohana ʻia nā pale kaumaha no ka hoʻoheheʻe ʻana i ka hao, nā kila, a me nā ʻili paʻa.
He aha ka manaʻo o nā helu a me nā leka ma nā lāʻau wili?
He ʻōnaehana helu ka American Welding Society (AWS) e hāʻawi ana i ka ʻike e pili ana i kahi electrode kikoʻī, e like me ke ʻano o ka hoʻohana ʻana a me ke ʻano o ka hoʻohana ʻana no ka ʻoi loa.

ʻO ka "E" e hōʻike ana i kahi electrode welding arc.ʻO nā huahelu mua ʻelua o ka helu 4-helu a me nā huahelu mua ʻekolu o ka helu 5-helu e kū nei i ka ikaika uʻi.No ka laʻana, ʻo E6010 ke ʻano o 60,000 paona i kēlā me kēia square iniha (PSI) ikaika tensile a ʻo E10018 ʻo ia ka 100,000 psi ka ikaika tensile.Hōʻike ka helu hope a i ke kūlana.No laila, ʻo "1" ke kū nei i kahi electrode kūlana āpau, "2" no ka electrode palahalaha a me ka pae, a me "4" no ka electrode palahalaha, ākea, kū i lalo a i luna.Hōʻike nā huahelu hope ʻelua i ke ʻano o ka uhi a me ke au kuʻi.4

ʻO ka ʻike ʻana i nā ʻano electrodes like ʻole a me kā lākou mau noi he mea kōkua ia e hana pololei i ka hana wili.E noʻonoʻo ʻia ke ʻano wili, nā mea welded, nā kūlana i loko/waho, a me nā kūlana wili.ʻO ka hoʻomaʻamaʻa ʻana me nā pū wiliwili like ʻole a me nā electrodes hiki ke kōkua iā ʻoe e hoʻoholo i ka electrode e hoʻohana ai no ka papahana wili.
