ERNiFeCr-2 Welding Waya (Inconel 718 / UNS N07718) - Nickel-Iron-Chromium Alloy Filler Metal for High-Strength, High-Temperature Applications
Mafotokozedwe Akatundu
ERNiFeCr-2 ndi waya wowotcherera wa chitsulo chachitsulo chachitsulo chachitsulo cha chromium champhamvu kwambiri, chomwe chimagwiritsidwa ntchito powotcherera Inconel 718 ndi zida zofananira. Lili ndi niobium (columbium), molybdenum, ndi titaniyamu, zomwe zimalimbikitsa kuuma kwa mvula ndikupereka mphamvu zolimba, kutopa, kukwawa, ndi kuphulika.
Chitsulo chofiyira ichi ndi choyenera kufunafuna zakuthambo, kupanga magetsi, ndi ntchito za cryogenic zomwe zimafuna mphamvu zamakina pakutentha kokwera. Ndi yoyenera kwa njira zonse zowotcherera za TIG (GTAW) ndi MIG (GMAW) ndipo imapanga ma welds okhala ndi ductility wabwino, mphamvu zabwino kwambiri, komanso kukana kusweka.
Zofunika Kwambiri
-
Mphamvu zabwino kwambiri zotentha kwambiri, kukana kutopa, komanso kupsinjika maganizo
-
Aloyi wowuma ndi mpweya wokhala ndi niobium ndi titaniyamu kuti makina azigwira bwino ntchito
-
Kukaniza kwambiri ku dzimbiri, ma oxidation, ndi makulitsidwe kutentha
-
Zopangidwira kuwotcherera Inconel 718 ndi ma aloyi a nickel ofanana ndi zaka
-
Zoyenera zazamlengalenga, turbine, cryogenic, ndi zida za nyukiliya
-
Smooth arc, spatter yochepa, ndi ma welds osamva crack
-
Zimagwirizana ndi AWS A5.14 ERNiFeCr-2 ndi UNS N07718 miyezo

Ntchito Zofananira
-
Zida za injini ya jet (ma disc, masamba, zomangira)
-
Ma turbine a gasi ndi zida zam'mlengalenga
-
Matanki osungira a cryogenic ndi zida
-
Zigawo za zida za nyukiliya ndi chitetezo
-
Mapangidwe a Chemical ndi apanyanja
-
Kupsinjika kwakukulu kumalumikizana mosiyanasiyana
