Nickelarc 122

AWS Specification :AWS A5.11 E NiCrMo-10

JIS Specification: NONE

Other Specification:NONE

 

I. APPLICATIONS:

Nickelarc 122 is suited for joining materials of the same nature, e.g. material No. 2.4602 NiCr21Mo14W and these materials with low alloyed steels such as for surfacing on low alloyed steels.

     For welding components in plants for chemical processes with highly corrosive media.

II. DESCRIPTIONS:

Good corrosion resistance against acetic acid and acetic hydride, hot contaminated sulphuric and phosphoric acis and other contaminated oxidizing mineral acids.

Nickelarc 122 can be welded in all positions except vertical-down. A stable arc and very easy slag removal.

III. NOTES ON USAGE:

Opening angle of the prepared seam approximately 70°, root gap approximately 2mm. Weld electrode with slight tilt and with a short arc. String beads are welded. The interpass temperature of 150°C and a maximum weaving width 2.5 x diameter of the electrode core wire should not be exceeded. Re-dry electrodes 2-3 hours at 250-300°C before use and weld them out of a warm electrode carrier.

IV. TYPICAL CHEMICAL COMPOSITION OF WELD METAL (%):

C	Si	Mn	Fe	Ni	Mo	Cr
