ʻO nā "H Channels" e pili ana i nā mea hana i hoʻohālikelike ʻia e like me ka leka "H" i hoʻohana mau ʻia i ke kūkulu ʻana a me nā noi hoʻolālā like ʻole.
Nā Kānāwai H:
ʻO nā kaha kila kila H nā ʻāpana hana i hōʻike ʻia e ko lākou ʻāpana ʻāpana H.Hana ʻia kēia mau kahawai mai ke kila kila, kahi huila pale ʻino i ʻike ʻia no kona lōʻihi, maʻemaʻe, a me ka hoʻopiʻi nani.Loaʻa i nā kaha kila kila H i nā noi i nā ʻoihana like ʻole, e like me ke kūkulu ʻana, ka hoʻolālā, a me ka hana ʻana, kahi i hoʻolilo ʻia ai ko lākou kūpaʻa ʻana a me ka ikaika i koho maikaʻi ʻia no ke kākoʻo a me ka hoʻolālā. nā mea hoʻolālā kahi e pono ai ka ikaika a me ka hiʻohiʻona nani.

He aha nā ʻano hana wili?
ʻO nāʻano hana hoʻoheheʻe e like me ka arc welding, ke kinoea pale aku (MIG/MAG welding), ka hoʻopalekana kū'ē, ka laser welding, plasma arc welding, friction stir welding, pressure welding, electron beam welding, a me nā mea'ē aʻe. ʻano o nā mea hana a me nā koi hana. Hoʻohana ʻia kahi arc e hana i nā wela kiʻekiʻe, hoʻoheheʻe i ka metala ma ka ʻili o ka mea hana e hana i kahi pilina.ʻO nāʻano hana hoʻoheheʻe arc maʻamau,ʻo ia hoʻi ka hoʻoheheʻe manual arc, argon arc welding, submerged arc welding, etc.ʻO ka wela i hanaʻia e ke kū'ē i hoʻohanaʻia e hoʻoheheʻe i ka metala ma kaʻili o ka mea hana e hana i kahi pilina.ʻO ke kuʻi kūʻē ʻana e pili ana i ka wiliwili kiko, wili wili a me ka wili bolt.
He aha nā mea maikaʻi o ka hoʻoheheʻe ʻana i ka arc submerged?
He kūpono ke kuʻekuʻe wāwae i lalo no ka automation a me nā wahi kiʻekiʻe.Hiki iā ia ke hoʻopau i ka nui o ka hana welding i kahi manawa pōkole a hoʻomaikaʻi i ka hana hana.He kūpono ke kuʻekuʻe wāwae i lalo no ka automation a me nā wahi kiʻekiʻe.Hiki iā ia ke hoʻopau i ka nui o ka hana welding i kahi manawa pōkole a hoʻomaikaʻi i ka hana hana.Hoʻohana maʻamau ʻia ka welding arc submerged e wili i nā ʻāpana metala ʻoi aku ka mānoanoa no ka mea ʻoi aku ka maikaʻi o kēia mau noi.Ma muli o ka uhiʻiaʻana o ka weld e ka flux, hiki ke pale ponoʻia ka oxygen mai ke komoʻana i ka wahi weld, a laila e ho'ēmi i ka hiki o ka oxidation a me ka spatter. mākau hana.I loko o ka hoʻoheheʻe ʻia ʻana, hiki ke hoʻohana ʻia nā uea wili a me nā arcs i ka manawa like e hoʻokō ai i ka wiliwili lehulehu (multi-layer) a hoʻomaikaʻi i ka pono.
Hoʻolauna i ke ʻano o ka kukuna H ?
ʻO ke ʻano keʻa o ke kila I-beam, i ʻike mau ʻia ʻo "工字钢" (gōngzìgāng) ma ka ʻōlelo Kina, ua like ia me ka huapalapala "H" i ka wā i wehe ʻia ai.ʻO ka mea maʻamau, ʻo ka ʻāpana keʻa he ʻelua mau kaola ākea (flanges) ma luna a me lalo a me kahi pahu waena kū pololei (pūnaewele).Hāʻawi kēia ʻano "H" i ka ikaika a me ka paʻa i ke kila I-beam, e lilo ia i mea hana maʻamau i ke kūkulu ʻana a me ka ʻenekinia. e like me nā kaola, nā kolamu, a me nā hale alahaka.ʻO kēia hoʻonohonoho hoʻonohonoho e hiki ai i ke kila I-beam ke puʻunaue pono i nā ukana ke kau ʻia i nā ikaika, e hāʻawi ana i ke kākoʻo paʻa.Ma muli o kona ʻano kū hoʻokahi a me nā hiʻohiʻona hoʻolālā, ʻike nui ka I-beam steel i ka hoʻohana nui ʻana i ka hana o ke kūkulu ʻana a me ka ʻenekinia.
Pehea e hōʻike ai i ka nui a me ka hōʻike ʻana o I-beam?
H——Kiekie
B——Ka laula
t1——Ka mānoanoa pūnaewele
t2——Ka mānoanoa o ka pā flange
h£——Ka nui o ka welding (i ka hoʻohana ʻana i ka hui pū ʻana o nā welds a me nā fillet, ʻo ia ka nui o ka wāwae wili i hoʻoikaika ʻia hk)
ʻO nā ana, nā ʻano a me nā ʻae ʻae ʻia o ke kila H-like welded
ʻO nā ʻāpana keʻa, ʻāpana keʻa, ke kaumaha kumu a me nā ʻāpana hiʻohiʻona keʻa o ke kila H-like welded.
ʻO kā mākou mau mea kūʻai
Manaʻo manaʻo mai kā mākou mea kūʻai mai
ʻO nā Kānāwai Kūleʻa Kūleʻa H he mau mea hana nui i hana ʻia mai ke kila kila kila maikaʻi loa.Hōʻike ʻia kēia mau kahawai i kahi ʻano "H" ʻokoʻa, e hāʻawi ana i ka ikaika a me ke kūpaʻa i nā ʻano hana like ʻole a me nā palapala hoʻolālā. ʻO ka hoʻolālā H-like e hoʻonui i ka hiki ke lawe i ka ukana, e hana i kēia mau ala kūpono no ke kākoʻoʻana i nā ukana kaumaha ma ke kūkuluʻana a me nāʻoihanaʻoihana.
Hoʻopili:
1. He mea koʻikoʻi ka hoʻopaʻa ʻana ma ka hihia o ka hoʻouna ʻana i ka honua kahi e hele ai ka lawe ʻana ma nā ala like ʻole e hiki ai i ka hopena hope loa, no laila ke kau nei mākou i ka manaʻo nui e pili ana i ka ʻeke.
2. Hoʻopili ʻo Saky Steel i kā mākou waiwai ma nā ʻano he nui e pili ana i nā huahana.Hoʻopili mākou i kā mākou huahana ma nā ʻano he nui, e like me,
