1. hoʻokaʻawale
E like me ka nui o ka carbon content, hiki ke hoʻokaʻawale ʻia ke kila kalapona i ʻekolu mau ʻāpana:
1) Haʻahaʻa kalapona kila C% ≤ 0.25
2) Medium carbon steel 0.25
3) Ke kila kalapona kiʻekiʻe C% > 0.6
Pahu Haahaa
Kalapona waena
Kiʻekiʻe-Kapona
2. weldability kālailai
ʻO ka nui o ke kalapona he mea nui ia no ka hoʻomohala ʻana i nā kaʻina hana welding. Ke piʻi aʻe ka ʻike kalapona, piʻi ka ikaika a me ka paʻakikī, ʻoiai ke emi nei ka plasticity a me ka paʻakikī, ʻoiai ke piʻi nei ke kaumaha. ʻO ka mea pili, ʻo ka haʻahaʻa o ke kalapona, ʻoi aku ka maikaʻi o ka weldability, no laila, ʻo ke kalapona ka mea maʻamau no ka hoʻokolokolo ʻana i ka paʻakikī o ka hoʻopili ʻana i ke kila kalapona, a pono e hoʻohana ʻia nā kaʻina hana kuʻi no nā ʻano kalapona like ʻole.
3. Ka hana welding
ʻO ke koho ʻana o nā mea hoʻoheheʻe kalapona e pili ana i ke kumu o "ka ikaika like"
1. Ke kila kalapona haʻahaʻa (ʻike mau ʻia ʻo ke kila māmā)
ʻO nā māka kila maʻamau e like me Q235 (i ʻike mua ʻia ʻo A3 steel), Q255, a me nā mea ʻē aʻe, ʻaʻole i lawe i nā hana kūikawā i ka wā e wili ai, ʻaʻole hoʻi i ka hoʻomehana ʻana a i ʻole ka hoʻopau ʻana.
2. Medium carbon steel
ʻO ke kila hoʻohana maʻamau e like me 30 #, 45 #, etc., 45 # ka mea no ka hana ʻana i nā lau a me nā faila, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā mea kuʻihao haʻahaʻa haʻahaʻa me ke kūpaʻa māwae maikaʻi, preheating 100-200 °C; Inā ʻaʻole maʻalahi ka preheat, hiki ke koho ʻia ka Cr-Ni austenitic stainless steel wili.
3. Ke kila kalapona kiʻekiʻe
Hoʻohana mau ʻia nā māka kila e like me 60Si2Mn, T8, T10 a pēlā aku. ʻO 60Si2Mn kahi kila puna maʻamau, maʻamau ʻaʻole e hoʻokō i ka hoʻomaʻamaʻa kuʻi ʻana, hoʻohana nui ʻia e like me ka re-weld, pono e 250-350 °C preheating, pono e kuʻi ʻia e hoʻopau i ke kaumaha, a me 650 °C ma hope o ka wela, hiki nō hoʻi. koho Cr-Ni austenitic kuhiliʻole kila mea
ʻO ka hā, nā mea pono e pono ai ka wiliwili lima lima kila māmā:
Electrode maloʻo wela
| 'ikamu | ʻAno ʻili | Huahana | Mahana | Manawa |
| Ke kila kalapona haʻahaʻa a me ke kila ikaika kiʻekiʻe | ʻAno hydrogen haʻahaʻa | E7016, E7048, E7015, E7015-G | 300-350 ℃ | 60 min |
| E7015, E8015-G, E9016-G, E9015-D1, E10015-D2, E12015-G | 330-380 ℃ | |||
| ʻO ka paʻakikī kiʻekiʻe a me ke ʻano hydrogen haʻahaʻa | E7016-G, E7015-G, E8015-G, E9015-G, E10015-G | 350-380 ℃ | 60 min | |

2. Pono e hoʻoneʻe ʻia ka wai, ka ʻaila, ka ʻōpala, a me nā mea ʻē aʻe ma luna o ka ʻili o ka mea kumu
3. E hoʻohana i ke ala hope i mua e wili ai i mea e pale aku ai i ka stomata ma kahi hoʻomaka
Pono e hoʻohana ʻia ka wiliwili pōkole pōkole, e like me nā ʻāpana oscillating, a ʻaʻole pono ka oscillation amplitude ma mua o 3 mau manawa o ke anawaena uea.
