He kūlana āpau ʻo AWS E312-17 a ua like loa me 312-16 akā ʻoi aku ka nui o ka silica ma ka uhi ʻana -17 a emi mai ka tita-um e hana ana i ka hopena "Spray-Arc" ke hoʻohana ʻia ma nā wili fillet ākea.

ʻO kahi electrode kūlana āpau i hoʻohui ʻia me ke kumu rutile kiʻekiʻe CrNi
Maikaʻi loa no ka hoʻoponopono ʻana i ka wili
Hoʻomohala kūikawā ʻia no nā kila paʻakikī ke hoʻopili ʻia, e like me nā papa pale kaua, nā kila Mn austenitic a me nā kila C kiʻekiʻe
ʻO ka weldability maikaʻi loa a me ka slag hoʻokuʻu ponoʻī
Hiki ke hoʻopili ʻia ma ka polarity AC a me DC+
ʻAno o kēia manawa: DC/AC+

He kūlana āpau ʻo AWS E312-17 a ua like loa me 312-16 akā ʻo ka uhi -17 he nui aku ka silica a emi iho ka titanium e hana ana i ka hopena "Spray-Arc" ke hoʻohana ʻia ma nā wili fillet ākea. Hoʻopuka pū kēia i kahi waihona wili me kahi ʻano ripple maikaʻi aʻe i ʻoi aku ka pālahalaha i ka concave. Loaʻa iā 312-17 kahi slag hau lohi e hāʻawi ana i nā ʻano lawelawe maikaʻi aʻe i ka wā e hoʻohana ai i kahi ʻenehana kauō. Koho maikaʻi loa ma nā kila paʻakikī e wili e like me ke kila paʻakikī ea, nā kila kalapona waena a me ke kiʻekiʻe. ʻO ka electrode kūpono e hoʻohana ai i kahi o ke kila kumu he papa kila ʻike ʻole ʻia. Kūpono no nā noi like ʻole e pili ana i ke kila paʻakikī manganese, ke kila pale, ke kila puna, ke kila rail, ke kila nickel clad, ke kila mea hana & make a me ke kila mokulele. Hoʻohana pinepine ʻia ma ke ʻano he papa kūkulu pale a me ka "buffer" i nā noi paʻakikī. Hoʻopaʻakikī ka hana a hiki i 200 Brinell. ʻO 312-17 ka ikaika tensile a me ka ikaika yield kiʻekiʻe loa o nā electrodes i uhi ʻia me ke kila kila maʻamau (ʻaʻole i hoʻokomo ʻia ka duplex stainless).
