Bayani: Ni307-4 na'urar lantarki ce mai tushen nickel tare da ƙarancin sodium mai ƙarancin hydrogen.Yi amfani da DCEP (lantarki na yanzu kai tsayetabbatacce).Yana da kyakkyawan aikin walda tare da barga mai ƙonewa, ƙarancin spatter, sauƙin cire slag,

da kyau weld.

Aikace-aikace: Ana amfani da waldi na nickel-chromium-baƙin ƙarfe gami, kamar Ni600, Ni800/800H da makamantansu ko nickel tushen superalloys tare da aiki zafin jiki na 900 ° C. Hakanan za'a iya amfani dashi don ƙananan zafin jiki na ƙarfe wanda ya ƙunshi Ni3% ~ 9%, kamar ASTM A333, A334, A353, A522, The waldi na A553 kuma za a iya amfani da dissimilar karfe waldi tsakanin Mo400, Ni825, bakin karfe da low gami karfe.
