IKE NUI WELDING
Mai ʻae i nā nīnau
E hoʻomau mau iā ʻoe
Paʻa ʻole ʻo Arc
ʻO ka hoʻoheheʻe ʻana
ʻO ka pipiʻi nui
ʻO ka hui nui o 9%Cr-9.5%Ni-1.0Mo-4% Mn-Si
hana i nā kuʻi kila ʻokoʻa me ke kūpaʻa māwae maikaʻi
E like me ke kuʻi ʻana i ke kila austenitic a me ke kalapona kila forgings a me ka hoʻolei ʻana; He palupalu a paʻa ke arc,
liʻiliʻi splash, nani hana, maikaʻi slag wehe, paʻa uea hānai, me ka maikai kuʻihao kaʻina hana.
Maikaʻi ka ripple
Haʻahaʻa hydrogen pae lua kuhiliʻole lima
electrode, ʻo ka mea nui ʻo 25.5Cr-10Ni-4Mo-0.25N
ʻO ka weld metala he austenitic a me ka ferritic biphase structure, a ʻo ka papa kuhikuhi kūʻē corrosion ʻo PRE>40.
Loaʻa iā ia ka ikaika kiʻekiʻe a me ke kūpaʻa maikaʻi i ka pitting a me ke koʻikoʻi o ka corrosion crack.
ʻOi aku ka maikaʻi o ka wiliwili ʻenehana, kūpaʻa arc, nani ka hana ʻana, ʻoluʻolu ripple, liʻiliʻi liʻiliʻi, maʻalahi ka wehe ʻana i ka slag.
ʻO ka slagging maʻalahi
