Applications
Welding of 50kgf/mm2 high tensile strength steels for structutes and rolling stock, and API 5LX, 5LS X52 – X65 pipes.
Characteristics
N – 7010G is a high cellulose type electrode for all positions. “Stove-pipe” welding of line pipes is specially easy. X-ray quality and mechanical properties of deposited metal are excellent.
GUIDELINE IN USAGE
Care should be taken for storing since coating flux contains more organic matter than normal electrodes and is apt to absorb moisture. Damp electrodes should be redried at 70 – 100oC for 60 minutes.
