ʻO ka electrode tungsten maikaʻi loa no kahi noi kikoʻī e pili ana i nā mea e like me ke ʻano o ka welding, ka mea welding a me ka welding current.Eia nō naʻe, ʻo kekahi mau electrodes tungsten i hoʻohana maʻamau ʻia:

1. Thoriated tungsten electrode: hoʻohana pinepine ʻia no ka hoʻoheheʻe ʻana o DC o ke kila kila, ka nickel alloy a me ka titanium.Loaʻa iā lākou nā waiwai hoʻomaka arc maikaʻi.

2. Tungsten-cerium electrode: kūpono no ka AC a me DC welding, hoʻohana pinepineʻia no ka hoʻopiliʻana i ke kila kalapona, ke kila kila, ka nickel alloy a me ka titanium.Loaʻa iā lākou nā waiwai hoʻomaka arc maikaʻi a me nā helu burnout haʻahaʻa.

3. Lanthanum Tungsten Electrodes: He mau electrodes versatile kēia i kūpono no ka hoʻoheheʻe ʻana o AC a me DC o ke kila kalapona, ke kila kila, nā nickel alloys a me ka titanium.Loaʻa iā lākou ke kūpaʻa arc maikaʻi a me ke ola lawelawe lōʻihi.

4. Zirconium tungsten electrode: hoʻohana maʻamau no ka hoʻoheheʻe ʻana o AC o nā alumini a me ka magnesium.He kūpaʻa maikaʻi ko lākou i ka haumia a hāʻawi i kahi arc paʻa.

He mea nui e nīnau i kahi loea welding a i ʻole e kuhikuhi i nā alakaʻi noi wili kūikawā e hoʻoholo ai i ka electrode tungsten maikaʻi loa no kahi hana wili kūikawā.

ʻAʻole ʻoi aku ka ikaika o Tungsten ma mua o ke daimana.ʻO Diamond kekahi o nā mea paʻakikī loa i ʻike ʻia a ʻike ʻia e ka paʻakikī a me ka ikaika.Hoʻokumu ʻia ia me nā ʻātoma kalapona i hoʻonohonoho ʻia i loko o kahi ʻano aniani kikoʻī, e hāʻawi iā ia i nā waiwai kūʻokoʻa.

ʻO Tungsten, ma ka ʻaoʻao ʻē aʻe, he metala paʻa loa a ikaika me kahi helu heheʻe kiʻekiʻe, akā ʻaʻole paʻakikī e like me ke daimana.Hoʻohana pinepine ʻia ʻo Tungsten i nā noi e koi ai i ka ikaika kiʻekiʻe a me ke kūpaʻa wela, e like me ka hana ʻana i nā mea hana kiʻekiʻe, nā pilina uila, a me ka ʻoihana aerospace.

I ka hōʻuluʻulu ʻana, ʻoiai he mea ikaika a paʻa ka tungsten, ʻaʻole paʻakikī e like me ke daimana.ʻO ka daimana kekahi o nā mea paʻakikī a paʻa loa i ʻike ʻia e ke kanaka.

He wahi hehee ki'eki'e loa 'o Tungsten he 3,422°C (6,192°F), i mea e ho'ohehe'e ai 'o ia i kekahi o na wahi hehee kiekie loa o na mea a pau.Eia nō naʻe, aia kekahi mau mea a me nā kūlana e hiki ke hoʻoheheʻe i ka tungsten:

1. Tungsten pono'ī: Hiki ke hoʻoheheʻe ʻia ʻo Tungsten me ka hoʻohana ʻana i nā wela kiʻekiʻe loa i hana ʻia e nā mea hana kūikawā e like me nā kapuahi uila a i ʻole nā ​​​​ʻano hoʻomehana holomua ʻē aʻe.

2. Tungsten-rhenium alloy: ʻO ka hoʻohui ʻana i kahi liʻiliʻi o ka rhenium i ka tungsten hiki ke hoʻohaʻahaʻa i ka helu heheʻe o ka hui.Hoʻohana ʻia kēia huila i kekahi mau noi wela kiʻekiʻe kahi e koi ʻia ai kahi helu heheʻe haʻahaʻa.

3. Hiki ke hoʻoheheʻe ʻia ʻo Tungsten ma ke alo o kekahi mau kinoea reactive a i ʻole ma lalo o nā kūlana kikoʻī i kahi kaiapuni i hoʻomalu ʻia.

ʻO ka mea maʻamau, pono ka hoʻoheheʻe ʻana i ka tungsten i nā kūlana koʻikoʻi ma muli o kona wahi heheʻe kiʻekiʻe, ʻaʻole maʻalahi ke hoʻokō.
