NIHONWELD N-14
AWS Specification: AWS A5.1 E6019
JIS Specification:

D4301

Other Specification:

EN499 E352RA

I. APPLICATIONS:

For all position welding of heavy duty structures such as ships, vehicles, building and bridges made of mild steel.

II. DESCRIPTIONS:

N-14 is an ilmenite type covered electrode for mild steel with the following features.

  • Excellent usability

  • Good x-ray soundness and excellent mechanical properties

  • Slag covering is uniform

  • Bead appearance is very beautiful

  • Usability in vertical or overhead welding is very good

III. NOTES ON USAGE:

  • If coating flux absorbs excessive moisture, arc and slag fluidity become unstable, spatters increase, and undercuts and blowholes are apt to occur. Damp electrodes should be re-dried at 70-120°C for 60 minutes.

  • Excessive high current and wide weaving deteriote X-ray quality. Use optimum current and limit weaving width to within 2.5 times electrode diameter.

TEST RESULT

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.
