NIHONWELD N-6027
AWS Specification: AWS A5.1 E6027
JIS Specification:

D4327

Other Specification:

DIN E4332AR11

I. APPLICATIONS:

Horizontal  and flat fillet welding of ships, bridges, structural steels of buildings and general structures.

II. DESCRIPTIONS: 

NIHONWELD N-6027 is an iron powder iron oxide type electrode which is designed for providing easy operation in manual welding. As it has excellent re-striking properties, it is suitable for intermittent welding. Extremely high efficient welding can be performed, because its speed ratio is high and its coating contains much iron that adds to the deposit.  

III. NOTES ON USAGE:

  • Adjust the welding current to keep the proper slag covering, because the optimum welding current is subject to the welding process and the surface condition of the steel plate.

  • In the case of manual welding, operate by contact welding.

  • In the case of gravity welding, the optimum speed ratio is 1.2-1.5

  • Dry the electrodes at 70-100 deg C for 30-60 minutes before use. Excessive moisture absorption causes undercuts and irregular beads.

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.
