J557SLA、J557SLB Haʻahaʻa Hydrogen Welding Rod AWS E8015-G Low Alloy Stick Electrodes no ka Arc Weld

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(%):

 Nā waiwai mīkini o ka weld metala:

Maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤6.0mL/100g (ʻano glycerin)

X-ray inspection: I ka helu

Manaʻo ʻia i kēia manawa:

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.
