ʻO nā kila Carbon haʻahaʻa weld E7015 mea hana
He kūpono no ka papa ikaika like a me ka ʻāpana o ke ʻano koʻikoʻi o ke kila kalapona a me ka hoʻoheheʻe ʻana i ke kila hao haʻahaʻa; Hoʻohana pinepine ʻia no ka ʻaila aila a me nā hana kīhāpai e like me ka wili pipeline.
He aha nā hiʻohiʻona?
●Haʻahaʻa sodium hydrogen type lima electrode, stable arc, liʻiliʻi splash.
●ʻO ka wehe ʻana i ka slag maʻalahi, ke kūpaʻa ahi maikaʻi loa.
●ʻOi aku ka maikaʻi o ka haki ʻana, ke kūpaʻa mechanical.
●Loaʻa iā ia ka hiki ke pale aku i ka haki ʻana o ka hydrogen (HIC) a me ka ʻakika corrosion cracking (SSC).
