Nā hiʻohiʻona a me ka hoʻohana ʻana o ka welding arc electrode

I ka hoʻohana ʻana i nā electrodes no ka wili arc, maʻalahi ka mīkini wili i koi ʻia, a hiki iā ʻoe ke koho i kahi mīkini wili AC a DC paha.Eia kekahi, ʻaʻohe pono o nā mea kōkua nui i ka wā e wili ai, ʻoiai aia nā mea kōkua maʻalahi.He maʻalahi kēia mau mīkini wiliwili i ke ʻano, maʻalahi ke kumukūʻai, a maʻalahi hoʻi e mālama.Ma muli o ka haʻahaʻa haʻahaʻa i ke kūʻai ʻana i nā lako, ua hoʻohana nui ʻia ka welding electrode arc i ka hana ʻoihana.

ʻAʻole wale ka hana o ka hoʻopiha ʻana i ka metala i loko o ka weldment, akā ʻaʻole pono e hoʻokomo i ke kinoea pale i ka wā e hoʻohana ai.I ka wā o ka hoʻomehana ʻana, ʻo ka manawa ma waena o ka electrode a me ka weldment e hana i kahi wai hoʻoheheʻe ʻia, aʻo ka electrode ponoʻī e hoʻopuka i nā huahana combustion e launa pū ana e hana i kahi kinoea pale e pale ai i ka wai hoʻoheheʻe a me ka weld.Eia kekahi, ua hoʻolālā ʻia ke ʻano o ke koʻokoʻo welding i mea ikaika loa i ka makani a ikaika i ka pale ʻana i ka makani, e hiki ai i ka wili kiʻekiʻe kiʻekiʻe i ka makani makani.

Electrode arcwiliwiliLoaʻa iā ia nā pōmaikaʻi o ka hana maʻalahi a me ka laulā noi ākea.He kūpono ia no ka wiliwili ʻana i kahi helu liʻiliʻi o nā huahana a i ʻole nā ​​​​puʻupuʻu liʻiliʻi, ʻoi aku ka paʻakikī o nā weld i paʻakikī ke wili me nā mīkini e like me nā ʻano ʻano like ʻole a me nā lōʻihi pōkole.I ka hoʻohana ʻana i ka ʻenehana wiliwili lāʻau lāʻau, ʻaʻole i kaupalena ʻia ke kūlana wili, a hiki ke hana maʻalahi a hiki i nā wahi haiki a i nā kūlana paʻakikī.Eia kekahi, he mea maʻalahi nā mea e pono ai no ka ʻenehana welding electrode arc, ʻaʻole hoʻohana ʻia ke kinoea kōkua, a ʻaʻole kiʻekiʻe ke kiʻekiʻe o ke akamai o ka mea hana.

ʻO ka hoʻohana ʻana o ka ʻenehana welding electrode arc he ākea loa, a he kūpono ia no ka hoʻopili ʻana i nā metala maʻamau āpau a me nā alloys.Ma ke koho ʻana i ka electrode kūpono, hiki ke hoʻokō ʻia ke kuʻi ʻana no nā mea like ʻole, me ke kila kila haʻahaʻa, ke kila kalapona, ke kila kila kiʻekiʻe a me nā metala non-ferrous like ʻole.Eia kekahi, hiki ke hoʻohana ʻia nā electrodes no ka hoʻopaʻa ʻana i nā ʻano mea hana like ʻole, e like me nā metala like ʻole, a me nā hana wili like ʻole e like me ka hoʻoponopono ʻana i ka hao hao a me ka hoʻoheheʻe ʻana o nā mea metala.Hiki i ka electrode pono'ī ke hāʻawi i kahi nui o ke kinoea pale e pale aku i nā pilikia e like me ka oxidation o ka weld.I ka manawa like, hiki i ka metala hoʻopihapiha ke hoʻonui i ka ikaika a me ka lōʻihi o ka weld.Ma nā wahi paʻakikī e like me ka makani ikaika, hiki i ka ʻenehana welding electrode arc ke mālama i nā hopena maikaʻi, e hōʻoiaʻiʻo ana i ka maikaʻi a me ka maikaʻi o nā hana wili.

Hoʻoholo ʻia ke kaʻina hana kuʻi ʻana e like me nā waiwai o ka mea metala, a pono nā mea metala like ʻole i nā ʻenehana kuʻi.ʻO ka ʻōlelo maʻamau, hiki ke hoʻopaʻa ʻia ke kila kalapona, ke kila haʻahaʻa haʻahaʻa, ke kila kila, ke kila pale wela, ke keleawe a me kā lākou mau ʻāpana e hiki ke hoʻopaʻa ʻia e nā ʻano kuʻihao maʻamau.Eia nō naʻe, no kekahi mau mea metala, e like me ka hao hoʻolei, ke kila ikaika a me ke kila paʻakikī, pono paha ka hoʻomaʻamaʻa mua ʻana a i ʻole ka mālama ʻana ma hope o ka wela, a i ʻole ke hoʻohana ʻana i nā ʻenehana wiliwili hybrid.Eia nō naʻe, ʻaʻole hiki ke hoʻopaʻa ʻia nā metala hoʻoheheʻe haʻahaʻa (e like me ka zinc, ke kēpau, ka tin a me ko lākou mau ala) a me nā metala refractory (e like me ka titanium, niobium, zirconium, etc.) me ka hoʻohana ʻana i nā kaʻina hana kuʻi.No laila, ma mua o ke kuʻi ʻana, pono e nānā pono a loiloi i ka mea, a koho i ka ʻenehana kuʻihao kūpono a me ke kaʻina hana e like me ke kūlana maoli.

ʻO ia mau huahana ka mea maʻamau i nā hale paʻakikī a me nā ʻano like ʻole, e koi ana i nā hana lima a me nā kaʻina hana wiliwili e hōʻoia i ka maikaʻi a me ka hilinaʻi o ka welding.No ka mea e koi ana ke kaʻina hana welding i nā mākau ʻoihana a me ka ʻike, ʻaʻole kūpono nā ʻano hana mechanized a me automated no kēia ʻano huahana.I ka manawa like, loaʻa i kēia ʻano huahana ke kumu kūʻai kiʻekiʻe a i ʻole kahi ʻāpana hana liʻiliʻi, a pono e hana ʻia ma ke ʻano i kuhikuhi ʻia.No laila, no kēia ʻano huahana, ʻo ke ʻano hana kūpono loa ʻo ia ka welding manual a me ka hana liʻiliʻi liʻiliʻi e hōʻoia i ka maikaʻi a me ka pono o ka hana.I ka manawa like, koi ʻia ka ʻenehana loea a me ka ʻike i ka hoʻonohonoho ʻana a me ka mālama ʻana e hōʻoia i ka hoʻohana maʻamau a me ka palekana o ka huahana.
