ʻO nā hao kalapona kiʻekiʻe Electrode E12018-G ma waho o ke kai kūʻai FPSO
He kūpono no ka wiliwili kila haʻahaʻa me ka ikaika like i ka mīkini hana.
ʻO ka maʻamau a mākou i hālāwai ai: GB/T32533 E8318-G, AWS A5.5 E12018-G & A5.5M E8318-G, ISO18275-A, ISO 18275-B: E8318-A
He aha nā
mau ano?
●ʻO ka pauka hao haʻahaʻa hydrogen potassium lima electrode, kiʻekiʻe melting efficiency.
●Hana maikaʻi loa i ka hopena wela haʻahaʻa.
●Paʻa paʻa, liʻiliʻi liʻiliʻi, hoʻoheheʻe maikaʻi, wehe maʻalahi.
●Hana X-ray maikaʻi, hana mechanical paʻa.
