GB：ER50-G
AWS：ER70S-G
Application：1. Used for welding all kinds of 500MPa structural steel parts, thick plates and thick pipelines. 2. Used for high speed welding on 500MPa base metals ：

ER70S-G

According with GB ER50-G
Corresponding with AWS ER70S-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: 1. Used for welding all kinds of 500MPa structural steel parts, thick plates and thick pipelines.
2. Used for high speed welding on 500MPa base metals.
