AWS A5.5 E11015-G

ISO 18275-B-E7615-GA

Characteristics and Application

AWS A55 E11015-G  is suitable for welding tensile strength equivalent to 780 MPa grade low alloy steel structure, such as WES, HW70, ASTMA514, A517, CFO, etc.

Features: It is a low hydrogen sodium type low hydrogen high toughness low alloy high strength steel electrode. It always adopts DC reverse and can be all-position welding. It can reach excellent welding performance, weld metal has good low temperature impact toughness and excellent crack resistance.

Notes on usage:

1. Electrode must be approved by 400-430℃ for 2 hour , then stay in 100-150 ℃ constant temperature box before welding, pick the electrode when use it.

2. The rust, oil, water and other impurities of the weld must be removed before welding.
3. You must use short arc welding, the swings should not be too large, narrow bead welding is appropriate.
4.To prevent producing arc porosity, arc plate should be adopted or use return method for arc welding. 5.Layer temperature and preheat temperature should maintain 90-130℃.
