WEHEWEHE:
Nā Uea ʻAla i Hoʻokomo ʻia i loko o ka Wai Hoʻoheheʻe ʻia nā Kila Haʻahaʻa
MĀHELE:
AWS A5.23: ʻO ka ECM4 Submerged Arc Solid Wire kahi electrode uea i hoʻohui ʻia me ka metala haʻahaʻa no ka hoʻoheheʻe ʻana i ka arc i lalo i nā noi ikaika kiʻekiʻe. AWS A5.23: Ua hui ʻo ECM4 me ka kemika AWS A5.23 M4, a ua hoʻolālā ʻia no nā pae ikaika tensile ma luna o 110 ksi.
KA PALAPALA NUI:
Nā noi hele hoʻokahi a me nā noi he nui me ka flux arc submerged i ʻōlelo ʻia, nā kila Low-Alloy ikaika kiʻekiʻe, nā kila Quench & Tempered, nā ʻāpana lako kaumaha, nā ʻāpana kūkulu, nā ʻili moku, nā kila i hoʻolei ʻia, nā ipu paila a me nā moku kaomi
Nā kila HSLA a me Q&T
Hana ʻana i ke ʻano kūkulu
Ka hana ʻana o ka Jack-up rig
Nā mōlina lako kaumaha
Nā kaola crane
NĀ HIʻONA:
Hiki i ke kaula hao-cored ke hāʻawi i nā helu hoʻokaʻawale i hoʻomaikaʻi ʻia i hoʻohālikelike ʻia me nā kaula paʻa i nā amperages like
Hāʻawi nā uea metala-core i nā ʻano komo ākea i hoʻohālikelike ʻia me nā uea paʻa ma nā ʻano hoʻohālikelike hoʻohui
Waihona ikaika kiʻekiʻe loa me ka paʻakikī haʻahaʻa haʻahaʻa maikaʻi loa i ke kūlana i hoʻopaʻa ʻia
Ua like nā koi kemika waiho weld me nā koi o nā uea paʻa EM4.
