NĀ PALAPALA:
He kūpono ia no ka hoʻopili ʻana i nā ʻāpana lahilahi o ka hoʻoheheʻe ʻana i ka hao a me nā ʻaoʻao mīkini, e like me nā poʻo cylinder, nā poloka ʻenekini hao hina hina nui, nā pahu pahu, a me nā mea hana mīkini a hiki koke.
NA ANOAI:
TQZ308ʻo ia ka nickel welding core, hoʻemi ikaika o ka graphite type coating iron rod.Hiki ke hoʻohana ʻia i ka AC a me DC kumu ʻelua a maʻalahi ke hana.I ka welding, ʻaʻole pono ka weldment e hoʻomaʻamaʻa.Loaʻa iā ia ke kūpaʻa māwae maikaʻi a me ka processability.
MAHELE:
1. Ma mua o ke kuʻi ʻana, pono e kālua ʻia nā electrodes no 1 hola me ka mahana o 150±10 ℃ ma mua o ka hoʻohana ʻana.
2 Hiki iā ia ke hoʻopau i ke koʻikoʻi kuʻihao a pale aku i ka māwae ma ka hammering ʻana i ke kuʻi wili.
3. I mea e hoemi ai i na mea haumia iloko o ka weld metala kumu, ka laula keokeo haiki, e hooikaika i ke ku'e o ka poha a me na waiwai hana, pono ia e hoohana i ka wiliwili li'ili'i o keia manawa ma ka wili anu.
ʻO ka hui ʻana o ka metala i waiho ʻia (ka hakina nui): %

| Waiwai maʻamau | ≤2.0 | ≤2.5 | ≤1.0 | ≤0.03 | ≤8.0 | ≥90 | ≤1.0 |
Ke kuhi nei i kēia manawa: (AC,DC+)

| Ke au wiliwili (A) | 60-90 | 90-110 | 120-150 |
Hoʻoponopono hoʻopololei welding:
No ka hoʻoponopono deformation i ke kūlana wela, pāpā loa ʻia ka hoʻoponopono ʻana i ka mīkini a me ka hammering ma ke ʻano o ka mahana brittle polū (300 ℃ ~ 500 ℃) e pale i nā māwae.
E hoʻolohe i nā koi e pili ana i ka wā e hoʻomehana ʻia ai ke ahi
ʻAʻole pono e hana hou i ka hoʻomehana ʻana ma ka ʻāpana like e pale aku i nā loli i ke ʻano metallographic a me nā waiwai mechanical o ke kila.
Mai hana i ka hoʻoponopono pinepine ʻana o ka ʻāʻī a me ka hoʻoemi ʻana i ka ʻāpana like.
No nā ʻāpana welded hardenable, pāpā loa ʻia ka hoʻoinu ʻana a me ka hoʻoilo wikiwiki.
Pono e hoʻoponopono ʻia nā ʻāpana welding e pono e hoʻopili ʻia ma mua o ka hoʻopili ʻana i mea e hoʻopau ai i ke koʻikoʻi o loko i ka wā annealing.I ka wā o ka annealing, pono e hoʻonoho paʻa ʻia nā ʻāpana welded i ʻole e deform hou.
ʻO ka wela wela e hoʻopololei ana i ka lapalapa ahi hiki ke 700 ℃ ~ 850 ℃ (fuchsia), a ʻaʻole pono ma mua o 900 ℃ (ʻulaʻula ʻulaʻula) no ke kila kila haʻahaʻa.
