Product Description

AWS ER70S-G
CO2 Gas Shielded Welding wire
                                                           GB/T 8110 ER50-G
                                                               AWS A5.18 ER70S-G
                                                          JIS YGW11

Introduction:The welding current of ER70S-G 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.

Application Used for welding all kinds of 500MPa structural steel parts, thick plates and thick pipelines as well as high speed welding on 500MPa base metals.
