Nā ʻano a me ka laulā o ka hoʻohana ʻana o ka electrode arc welding

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

ʻAʻole wale ka hana a ka ʻenehana kuʻihao arc electrode i ka hoʻopiha ʻana i ka metala i loko o ka weldment, akā ʻaʻole pono hoʻi e hoʻokomo i ke kinoea pale hou i ka wā e hoʻohana ai. I ka wā e hoʻomehana ai i ke arc, hana ke au ma waena o ka electrode a me ka weldment i kahi loko i hoʻoheheʻe ʻia, ʻoiai ʻo ka electrode ponoʻī e hana i nā huahana kuni e launa pū ana e hana i kahi kinoea pale e pale ai i ka loko i hoʻoheheʻe ʻia a me ka weld. Eia kekahi, ua hoʻolālā ʻia ke ʻano o ke koʻokoʻo kuʻihao e kūpaʻa loa i ka makani a ikaika i ka pale ʻana i ka makani, e hiki ai ke kuʻihao kiʻekiʻe i kahi ʻano makani.

ʻElectrode piʻokuʻihaoLoaʻa iā ia nā pono o ka hana maʻalahi a me ka laulā o ka noi. He kūpono ia no ka hoʻoheheʻe ʻana i kahi helu liʻiliʻi o nā huahana a i ʻole nā ​​​​pūʻulu liʻiliʻi, ʻoiai kēlā mau hoʻoheheʻe paʻakikī e hoʻoheheʻe me nā mīkini e like me nā ʻano ʻē a me nā lōʻihi pōkole. Ke hoʻohana nei i ka ʻenehana hoʻoheheʻe arc stick, ʻaʻole i kaupalena ʻia ke kūlana hoʻoheheʻe, a hiki ke hana maʻalahi ʻia ma nā wahi haiki a i ʻole nā ​​​​kūlana paʻakikī. Eia kekahi, he maʻalahi nā lako e pono ai no ka ʻenehana hoʻoheheʻe arc electrode, ʻaʻohe kinoea kōkua i hoʻohana ʻia, a ʻaʻole kiʻekiʻe loa ka pae akamai o ka mea hoʻohana.

He ākea loa ka hoʻohana ʻana o ka ʻenehana wili uila electrode arc, a kūpono ia no ka wili ʻana i nā metala maʻamau a me nā mea hoʻohuihui. Ma ke koho ʻana i ka electrode kūpono, hiki ke hoʻokō ʻia ka wili ʻana no nā mea like ʻole, me ke kila haʻahaʻa haʻahaʻa, ke kila kalapona, ke kila kiʻekiʻe a me nā metala ʻole ferrous like ʻole. Eia kekahi, hiki ke hoʻohana ʻia nā electrodes no ka wili ʻana i nā ʻano hana like ʻole, e like me nā metala like ʻole, a no nā hana wili like ʻole e like me ka hoʻoponopono ʻana i ka wili hao i hoʻolei ʻia a me ka wili ʻana i nā mea metala like ʻole. Hiki i ka electrode ponoʻī ke hāʻawi i kahi nui o ke kinoea pale e pale aku i nā pilikia e like me ka oxidation o ka wili. I ka manawa like, hiki i ka metala hoʻopihapiha ke hoʻonui i ka ikaika a me ke kūpaʻa o ka wili. I nā wahi ʻino e like me nā makani ikaika, hiki i ka ʻenehana wili uila electrode arc ke mālama i nā hopena maikaʻi, e hōʻoiaʻiʻo ana i ka maikaʻi a me ka pono o nā hana wili.

Hoʻoholo ʻia ke kaʻina hana kuʻihao e like me nā ʻano o ka mea metala, a pono nā ʻano hana kuʻihao like ʻole i nā mea metala like ʻole. Ma ke ʻano laulā, hiki ke kuʻihao ʻia ke kila kalapona, ke kila metala haʻahaʻa, ke kila kila ʻole, ke kila kūpaʻa wela, ke keleawe a me kā lākou mau mea metala e nā ʻano kuʻihao maʻamau. Eia nō naʻe, no kekahi mau mea metala, e like me ka hao i hoʻolei ʻia, ke kila ikaika kiʻekiʻe a me ke kila paʻakikī, pono paha ka hoʻomehana mua ʻana a i ʻole ka mālama ʻana ma hope o ka wela, a i ʻole hiki ke hoʻohana ʻia nā ʻano hana kuʻihao hybrid. Eia nō naʻe, ʻaʻole hiki ke kuʻihao ʻia nā metala haʻahaʻa haʻahaʻa (e like me ka zinc, ke kēpau, ka tin a me kā lākou mau mea metala) a me nā metala refractory (e like me ka titanium, niobium, zirconium, a pēlā aku) me ka hoʻohana ʻana i nā kaʻina hana kuʻihao maʻamau. No laila, ma mua o ka kuʻihao ʻana, pono e kālailai 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 ka maʻamau, he mau ʻano paʻakikī a me nā ʻano like ʻole kēlā mau huahana, e koi ana i nā hana lima a me nā kaʻina hana kuʻi palupalu e hōʻoia i ka maikaʻi a me ka hilinaʻi o ka kuʻi ʻana. ʻOiai ke koi nei ke kaʻina hana kuʻi i nā mākau ʻoihana a me ka ʻike, ʻaʻole kūpono nā ʻano hana hana mīkini a me ka hana automated no kēia ʻano huahana. I ka manawa like, he kumukūʻai kiʻekiʻe kēia ʻano huahana a i ʻole kahi pūʻulu 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 ka kuʻi lima a me ka hana ʻana i nā pūʻulu liʻiliʻi e hōʻoia i ka maikaʻi a me ka pono o ka hana ʻana. I ka manawa like, pono pū ka ʻenehana ʻoihana 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.
