Mai ʻae i nā nīnau
E hoʻomau mau iā ʻoe
Paʻa ʻole ʻo Arc
ʻO ka hoʻoheheʻe ʻana
ʻO ka pipiʻi nui
Hoʻohana nui ʻia ma waho o ka ʻaila a me ke kinoea, kemika,
ka ʻaila a me nā ʻoihana petrochemical i ka ʻōnaehana pipeline,
kahe laina laina riser, wili paipu ohi;
He kūpono no ka wiliwili ʻana o 25%Cr biphase stainless steel, e like me
UNS 32550(AIloy255)S32750, S32760 a me UNS J93370, J93380, J93404 a me CD4MCuN hoolele.
Maikaʻi ka ripple
Haʻahaʻa hydrogen super duplex kuhiliʻole lima electrode,
ʻO nā mea nui he 25.5Cr-9Ni-3.8Mo-0.7Cu-0.7W-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.
ʻO ka ʻenehana wili maikaʻi maikaʻi loa, ka arc kūpaʻa, ka liʻiliʻi liʻiliʻi, maʻalahi ka wehe ʻana i ka slag, ka hana nani, nā nalu palupalu.
ʻO ka slagging maʻalahi
