ACCORD WITH: GB E5015-G

EQUIVALENT NORM: AWS E7015-G

DESCRIPTION:

·GSE.7015-G is low alloy steel welding electrode covered with a sodium low hydrogen type coating.DC is applied and the electrode should be contacted reversed polarity. During welding, it has the features as follows: deep penetration,small spatters,fine appearance and slag easy to remove .And it achieves good mechanical properties of high tensile strength and excellent toughness.

APPLICATIONS :

·Suitable for welding structures fabricated by low alloy steel,medium and high carbon steel,such as offshore platforms,ships,high press vessels,etc.

ATTENTION:

a.Welding electrodes should be baked at the temperature of 350℃ for one hour before welding.

b.Before welding,the weld metal must be cleared away impurities,such as rust,oil,moisture,etc.

c.Short arc and narrow weld bead are recommended in welding.
