AWS A5.5 E10015-G

ISO 18275-B-E6915-GA

Characteristics and Application

AWS A5.5 E10015-G is suitable for welding low alloy steel structure equivalent to the tensile strength of 690 MPa. Features: It is a low hydrogen sodium type coating of ultra-low hydrogen and high toughness low alloy high strength steel welding rod. It always adopts DC reverse and can be all-position welding. It can reach excellent welding performance, stable arc, low spatter, easy slag removal and good weld appearance. Welded joints have good cold bending properties, good crack resistance and anti-knock properties, weld metal has good ductility and toughness.

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℃.
