AWS A5.4 E312-17 Kuʻikuʻi Kuʻihao Electrodes Arc lāʻau wiliwili lāʻau

ʻO AWS E312-17 kahi kūlana āpau a like loa me 312-16 akā ʻoi aku ka nui o ka silica a me ka liʻiliʻi o ka titani-um i ka -17 e hana ana i kahi hopena "Spray-Arc" ke hoʻohana ʻia ma nā welds fillet horizontal.

Hoʻokaʻawale:

AWS A5.4 E312-17

ISO 3581-A E 29 9 R 1 2

KA HOIKE ANA

A rutile-kumu kiʻekiʻe CrNi-alloyed a pau kūlana electrode

Maikaʻi no ka hoʻoponopono wili

Hoʻomohala kūikawā no nā kila paʻakikī e wili, e like me nā pā kaua, austenitic Mn-steels a me nā kila C kiʻekiʻe.

ʻOi loa ka weldability a me ka hoʻokuʻu ʻana iā ia iho

Weldable ma AC a me DC + polarity

ʻAno i kēia manawa: DC/AC+

Huina Kemika o Inweld 312-17

ʻOi aku ka nui o nā waiwai hoʻokahi ke ʻole i kuhikuhi ʻia.

ʻO ka wehewehe a me nā noi

ʻO AWS E312-17 kahi kūlana āpau a like loa me 312-16 akā ʻoi aku ka nui o ka silica a me ka liʻiliʻi o ka titanium i ka uhi -17 e hana ana i kahi hopena "Spray-Arc" ke hoʻohana ʻia ma nā welds fillet horizontal.Hoʻopuka pū kēia i kahi waihona weld me kahi hiʻohiʻona ripple ʻoi aku ka palahalaha i ka concave.Loaʻa iā 312-17 kahi ʻōpala maloʻo mālie e hāʻawi ana i nā hiʻohiʻona maikaʻi i ka wā e hoʻohana ai i kahi ʻenehana kauo.ʻO ka koho maikaʻi loa ma nā kila paʻakikī e like me ke kila paʻakikī ea, nā kila kalapona kiʻekiʻe.ʻO ka electrode kūpono e hoʻohana ai i kahi o ka metala kumu he ʻano kila i ʻike ʻole ʻia.He kūpono no nā ʻano hana like ʻole e pili ana i ka manganese-hardening steel, ke kila kila, ke kila puna, ke kila hao, ke kila nickel aahu, ka mea hana a me ke kila make a me ke kila mokulele.Hoʻohana mau ʻia e like me ke kūkulu ʻana a me ka papa "buffer" i nā noi paʻakikī.Paʻakikī ka hana a hiki i 200 Brinell.Loaʻa iā 312-17 ka ikaika tensile kiʻekiʻe a me ka hoʻoulu ʻana o nā electrodes i uhi ʻia i ke kila kila (ʻaʻole i hoʻokomo ʻia ka duplex stainless).
