Description
D&H1260 is a nickel base electrode. It gives soft and smooth arc, which is easy to strike and re-strike. It is easy to operate in AC also. The weld metal is of radiographic quality and displays a good combination of strength and impact strength even at minus 196°C. Electrodes of sizes up to 3.15 mm dia metal can be used for welding in allpositions. It is recommended to use other sizes in horizontal and flat positions for achieving better results. Ideal for welding 9% Nickel steel for cryogenic storage tanks for LNG and other similar alloys as well as the clad side of joints in steel clad with a Ni- Cr-Mo alloy and for welding Ni-Cr-Mo alloys to steel and to other nickel base alloys.
