AWS A5.5 E8016-B2
Hōʻike: R306 he pearlitic heat-resistant steel electrode me ka haʻahaʻa-hydrogen potassium coating i loaʻa ka 1% Cr - 0.5% Mo. Hiki ke hoʻohana ʻia ʻelua AC a me DC, a hiki ke welded ma nā kūlana āpau.Pono e hoʻomaʻamaʻa ʻia ka weldment i 160 ~ 250 ° C ma mua o ke kuʻi ʻana.
Hoʻohana: Hoʻohana ʻia no ka wili ʻana i ka Cr 1% - Mo 0.5% ke kila wela wela nona ka mahana hana ma lalo o 520 ℃, e like me nā paipu boiler, nā ipu kaomi, nā vaporizers a me nā mea hoʻomaʻemaʻe ʻaila, etc.
ʻO ka hui kemika o ka weld metala(%):

Ke au wiliwili (A) | 60 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 210 |
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.
