Nā ʻano a me nā noi

TheweldmetalofE309/309L loaʻa nā Cr Ni ma mua oE 308/308L.Loaʻa iā ia ka nui o ka ferrite i loko o ka microstructure, hāʻawi iā ia i kahi kūpaʻa maikaʻi loa i ka haki wela.ua hoʻolālā ʻia no ka hoʻohui ʻana i ke kila maʻalahi i ke kila kila, ke kila kila a me ke kila me ka weldability maikaʻi ʻole.ʻO nā metala kumu prop e komo pū ana me ka pā kila kila, ke kaula kila, ka paipu kila, ka paipu hoʻoili wela, ka pahu hao kaomi, ka hoʻolei ʻana a me ka hoʻopaʻa ʻana.

Nā memo no ka hoʻohana ʻana

1. E hoʻomaʻemaʻe i nā mea ʻino ma luna o ka metala kumu, ka ʻāʻī a me ka hele ʻana e hele me ka pulupulu kila
2.Maintaining pōkole arclength aspossible ua paipai nui ia.I ka wā e wili ai me ke ʻano ulana, pono e hoʻomalu ʻia ka laulā mov i loko o 2.5 manawa o ka dia o ka uea.
3. E hoʻomaloʻo i nā electrodes ma 250 ~ 300 ℃ no 60 mau minuke ma mua o ka hoʻohana ʻana.E lawe i nā mea hoʻopau no ka ʻai ʻana i ka lā haif a mālama i ke kaiapuni ma 100 ~ 150 ℃ i ka wā o ke kaʻina hana kuʻi.
4. E hoʻohana i ke au haʻahaʻa no ka pale ʻana mai ka pohā a hōʻemi i ka dilution metala kumu.
