AWS E312-17 waa meel-dhan waxayna aad ugu egtahay 312-16 laakiin dahaarka -17 wuxuu ka kooban yahay silica badan iyo titani-um yar oo abuuraya saameyn "Spray-Arc" marka loo isticmaalo alxanka fillet-ka ee toosan.
Kala-soocidda:
AWS A5.4 E312-17
ISO 3581-A E 29 9 R 1 2
SHARAXAAD GUUD
Elektrod boos oo dhan ah oo CrNi-da ah oo leh saldhig sare oo rutile-base ah
Aad ugu fiican alxanka dayactirka
Gaar ahaan loogu talagalay biraha ay adag tahay in la alxamo, sida taarikada hubka, biraha Mn-ga ee austenitic iyo biraha C-ga ee sare
Alxan aad u fiican iyo slag is-sii daaya
La dhaqi karo marka la isticmaalayo AC iyo DC+ polarity
Nooca hadda jira: DC/AC+

Sharaxaadda iyo Codsiyada
AWS E312-17 waa meel-dhan waxayna aad ugu egtahay 312-16 laakiin dahaarka -17 wuxuu ka kooban yahay silica badan iyo titanium yar oo abuuraya saameyn "Spray-Arc" marka loo isticmaalo alxanka fillet-ka ee toosan. Tani waxay sidoo kale soo saartaa kayd alxan oo leh muuqaal jilicsan oo siman oo u siman in la gooyo. 312-17 wuxuu leeyahay slag gaabis ah oo barafoobaya oo siinaya astaamo maarayn oo wanaagsan marka la isticmaalayo farsamada jiidista. Doorasho aad u fiican oo ku saabsan biraha adag in la alxamo sida birta hawo-adaygta, biraha kaarboonka dhexdhexaadka ah iyo kuwa sare. Elektrode-ka ugu fiican ee la isticmaalo halkaas oo biraha salka ahi yahay heer aan la garanayn oo bir ah. Ku habboon codsiyo badan oo kala duwan oo ku lug leh birta adag ee manganese, birta hubka, birta guga, birta tareenka, birta nikkel-ka, birta qalabka & birta dhiman iyo birta diyaaradaha. Waxaa badanaa loo isticmaalaa lakabka u adkaysta xirashada iyo "buffer" ee codsiyada adag. Shaqadu waxay adkaataa ilaa 200 Brinell. 312-17 waxay leedahay xoogga ugu sarreeya ee jiidista iyo wax-soo-saarka ee elektroodhada birta aan dahaarka lahayn ee caadiga ah (aan dahaarka laba-geesoodka ah lagu darin).
