Characteristics and Application
AWS A5.5 E7010-A1 Welding rods, welding electrode is a high cellulose type electrode for DC(+) welding. The welding can work in all ood crack resistance, deep penetration, stable arc, and excellent weldability positions with g when the welding condition is difficult due to narrow space or other reasons. It is especially designed for welding of the pipes, high pressure pipes, oil tanks, and boilers due to its good X-ray soundness.

Notes on usage:
1 Dry the electrodes at 60-70℃ for 30 minutes before using.
2. Lower current is recommended. Better to use straight or small weaving method for verticaldown position.
3 pre-heat the workpiece at 100-200℃ and PWHT at 620-680℃.
4. use DC(+) polarity.
