I. APPLICATIONS:

Transmission and distribution pipelines up to X-70

II. DESCRIPTIONS:

N-8010G is a high cellulose electrode designed specifically for vertical down welding of all passes on high tensile pipe. These electrodes are characterized by a steady, forceful, concentrated arc to insure good penetration and wetting action. The slag is fast freezing, minimizing slag interference, and allows for easy control of the weld shape and size.

III. NOTES ON USAGE:  

The root pass is deposited in the vertical down position. A drag technique is used and the electrode is pressed tightly into the joint. The second or hot pass should be deposited as soon as possible after the root pass. The current should be high enough to burn out any possible wagon tracks or slag. A slight weaving technique is usually employed. The filler passes are applied using a weaving technique in order to completely fill the joint. Excessive  travel speed should always be avoided to lessen any chance of porosity. Pre-heat and interpass temperatures between 300 °C and 400 °C are recommended.

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.
