Other Specification:

PHIL MARKET ONLY

 FOR PHILIPPINE MARKET ONLY

I. APPLICATIOINS:

Welding of cars, vehicles, machines and general light structural steel.

II. DESCRIPTIONS:

N-12/N-12A is a High Titania type electrode. Its weld metal has a good bead appearance with shallow penetration. It is suitable for welding of steel sheets and general structures.

III. NOTES ON USAGE:

  • Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but also causes increase of spatter, under-cut and insufficient slag covering.

  • Dry the electrodes at 70-100 degrees C for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosities.

  • Excessive drying before use causes less in penetration and overheating of the electrode.

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.
