DA5016G

Other Specification:

I. APPLICATIONS:

Welding of 50 kg/mm class high tensile weather-proof steel of buildings, bridges, and vehicles.

II. DESCRIPTIONS:

 N-7016W is a low hydrogen type electrode for all position welding of 50kg/mm2 class high tensile weather proof steel.

  • Excellent mechanical properties.

  • Good notch toughness in low temperature.

  • X-ray performance and mechanical usability are good.

        III. NOTES ON USAGE:

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

  • Adopt back step method or strike the arc on a small steel plate prepared for this purpose to prevent blowholes at the arc starting.

  • As excessive heat-input deteriorates impact values, weld with proper heat-input selected according to the impact values required.

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.
