Nickelarc 112
AWS Specification : AWS A5.11 E NiCrMo-3
JIS Specification: NONE
Other Specification: DIN 1736 EL-NiCr 20Mo9Nb
I. APPLICATIONS:
More common uses of Nickelarc 112 include the nuclear industry where it is used for pressure vessel superheaters, steam separators and tube plates. This electrode is commonly used in cryogenic installations; chemical and petrochemical applications; and for heat treatment and case hardening industrial furnace parts. More specific uses include joining Inconel® 625, 718, X-750 and 760 to 9% nickel steels; for welding Incoloy® 825 to carbon steel, stainless steel and low alloy steel; for joining Inconel® 625, Monel® K-500, Incoloy® 800 and 825 to Inconel® 706, 718 and X-750; and for joining Inconel® 825 and 800.I
II. DESCRIPTION:
Nickelarc 112 is a nickel-chromium-molybdenum flux-coated electrode designed for shielded metal-arc welding of Inconel® 625 or 601, for high strength welds on 9% nickel steels and for overlaying carbon steel. Nickelarc 112 is also used for joining dissimilar combinations of steels or stainless steels to nickel-iron-chromium alloys such as Incoloy® 800 or 801.
III. NOTES ON USAGE:
-
Its weldability is as same as austenitic stainless steels.
-
Keep the interlayer temperature under 100ºC and cool it as fast as possible.
-
Keep the welding current as low as possible.
-
Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.
