DESCRIPTION:
ʻO nā uea i hoʻopaʻa ʻia i loko o ka wai i hoʻopaʻa ʻia
KĀKAHI:
ʻO AWS A5.23: ECM4 Submerged Arc Solid Wire he mea hoʻoheheʻe haʻahaʻa haʻahaʻa i hoʻohuihui ʻia metala no ka hoʻoheheʻe ʻia ʻana o ke arc i loko o nā noi ikaika kiʻekiʻe.AWS A5.23: Ua hui ʻo ECM4 me AWS A5.23 chemistry M4, a ua hoʻolālā ʻia no nā pae ikaika tensile ma luna o 110 ksi.
NOHO NUI:
Nā noi hoʻokahi a me ka nui me ka arc flux i ʻōlelo ʻia i loko o ka wai, High-Strength Low-Alloy steels, Quench & Tempered steels, Nā mea hana kaumaha, nā mea hana, nā ʻili moku, nā kila hoʻolei, ka paila a me nā moku kaomi
HSLA a me Q&T kila
Kapili hale
Ka hana rig Jack-up
Nā papa hana kaumaha
Kaola crane
HI‘OHIA:
Hiki i nā uea metala ke hāʻawi aku i ka maikaʻi o ka hoʻopaʻa ʻana i nā uea paʻa i nā amperage like
Hāʻawi nā uea i hoʻopaʻa ʻia metala i nā kiʻi kikoʻī ākea e hoʻohālikelike ʻia me nā uea paʻa ma nā ʻāpana welding like.
ʻO ka waihona ikaika kiʻekiʻe loa me ka paʻakikī haʻahaʻa haʻahaʻa maikaʻi loa i ke kūlana as-welded
Ua like nā koi kemika weld deposit me nā uea paʻa EM4
