AWS Specification: AWS A5.5 E12016-G
JIS Specification:

NONE

Other Specification:

 

I. APPLICATIONS:

For heat treatable low alloy steels, such as SCM21/4 chrome-molybdenum steel, SNCM8 Ni-Cr-Mo steel, high tensile steels such as WEL-TEN80/80C/80P/80E,ASTM A486 Gr120/A508 Gr5a.4a/A543 GrB3.C, etc.

II. DESCRIPTIONS:

N-12016-G is a low hydrogen electrode for the welding of 830N/mm2 grade high tensile steel in all positions. Good crack resistance and mechanical properties, and good X-ray soundness can be secured because of the low hydrogen content of weld metal.

III. NOTES ON USAGE:

  • Dry the electrodes at 300-350°C for 30-60 minutes before use.

  • Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.

  • Keep the arc as short as possible.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
