GB：ER55-G
AWS：ER80S-G
Application：Suitable for welding high tension steels, normally applied in the construction, structural parts of bridges and pressure boiler.：

ER80S-G

According with GB ER55-G
Corresponding with AWS ER80S-G
JIS YGW11

Introduction: The welding current has been strengthened to a great extent and the welding efficiency has been improved. Because the grains of the deposited metal have been refined, both the tensile strength and the yield strength are close to the upper limit of the standard of classification society for 50kg class welding materials. The impact absorbed energy has been improved obviously.

Applications: Suitable for welding high tension steels, normally applied in the construction, structural parts of bridges and pressure boiler.
