AWS E6012 Nā Koʻokoʻo Welding

ʻO ka wehewehe pōkole:

ʻO E6012 kahi electrode kumu nui e hāʻawi i nā hiʻohiʻona bridging maikaʻi loa, ʻoi aku hoʻi no nā noi me ka maikaʻi ʻole.

ʻO E6012 kahi electrode kumu nui e hāʻawi i nā hiʻohiʻona bridging maikaʻi loa, ʻoi aku hoʻi no nā noi me ka maikaʻi ʻole.

Loaʻa iā E6012 maikaʻi, kūpaʻa arc a hana i nā kahawai kiʻekiʻe me ka haʻahaʻa haʻahaʻa.Hiki ke hoʻohana ʻia ʻo E6012 me ka mana AC a me DC.

Nā mea hoʻohana maʻamau: nā mea mahiʻai, ka hoʻoponopono maʻamau, ka hana ʻana i nā mīkini, nā lako metala, ka hao hoʻonaninani, nā ʻāpana metala, nā pahu.

I. NUI:

ʻO nā mea kila māmā, nā puka aniani a me nā pahu hao a me nā pā, ka ipu hao, ka wili ʻana o nā paipu i hoʻopaʻa ʻole ʻia, nā hale kila no nā hale, nā noho kila a me nā pākaukau, nā alapiʻi kila a me nā ana māmā ʻē aʻe.

II.DESCRIPTION:

ʻO kahi kūlana āpau i manaʻo nui ʻia ʻo Shielded Metal Arc Welding electrode me nā hiʻohiʻona fusion maikaʻi a me ke komo ʻana.Maikaʻi no ka hoʻopaʻa ʻana i nā hakahaka ma nā hana kūpono ʻole.Hoʻohana maʻalahi ma luna o nā metala māmā a me nā hale kila kaumaha.He laumania, he poepoe, a he mau lei me ka ili pili.He convex nā aʻa me ka ʻoki ʻole ʻia.ʻO kona kūlana holoʻokoʻa, i hui pū ʻia me kahi metala weld maloʻo wikiwiki a me kahi arc ikaika e lilo ia i electrode kūpono no ka hale hana a me nā kūlana kahua.ʻO nā hiʻohiʻona deposition maikaʻi loa i ka wā e wiliwili ai i ka vertical-up a me ka vertically-down.Hele maʻalahi ka slag a ma ka hapanui o nā hihia e hoʻokuʻu iā ia iho.

III.NĀ MANAʻO NO KA HOʻohana:

E noʻonoʻo ʻaʻole e oi aku i ka laulā o nā au kūpono.ʻAʻole hoʻohaʻahaʻa wale ke kuʻi ʻana me ka nui o ke au i ka leo X-ray, akā ke kumu hoʻi i ka piʻi ʻana o ka spatter, under-cut a lawa ʻole ka uhi ʻana.

E hoʻomaloʻo i nā electrodes ma 70-100 degere C no 30-60 mau minuke ma mua o ka hoʻohana ʻana.Hoʻemi ka hoʻohana ʻana i ka wai nui i ka hoʻohana ʻana a hiki ke hopena i kekahi mau porosities.

ʻO ka hoʻomaloʻo nui ʻana ma mua o ka hoʻohana ʻana e emi iho ai ke komo ʻana a me ka wela o ka electrode
