Haʻahaʻa Alloy Steel Weld Electrode
J557SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Hōʻike: He haʻahaʻa hydrogen sodium uhi electrode kūikawā no ke kila aluminized.E hoʻohana i ka DCEP (direct current electrode positive), a hiki ke wili ʻia ma nā kūlana āpau me ka hana pōkole pōkole.Hiki ke wili pololei ʻia ʻo J557SLA me ka ʻole o ka wehe ʻana i ka papa aluminized ma ka ʻili o ka groove ma mua o ke kuʻi ʻana.Akā ʻo ka J557SLB pono e wehe i ka papa aluminized ma ka ʻili o ka groove ma mua o ke kuʻi ʻana.
Hoʻohana: Hoʻohana ʻia ia no ka wili ʻana i ka hale kila aluminized ma lalo o ke ʻano corrosion o ka hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate a me ka hydrogen nitrogen me ka mahana hana ma lalo o 540 ° C.E like me nā paipu paila, nā lako hoʻomaʻemaʻe ʻaila, nā mea hoʻomomona a me nā paipu mahu, etc.
ʻO ka hui kemika o ka weld metala(%):

Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma kahi o 350 ℃ ma mua o ka hana wili;
2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka ʻaila unahi, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana.
