GMAW Solid Wire AWS A5.18 ER70S-g CO2 mig welding wire

Applications:

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

Characteristics:

This GMAW wire is for Rm 500MPa level carbon steel with shield gas of CO2 or M21.

Small spatter, beautiful appearance, high deposition efficiency and small weld metal porosity sensibility.

 

WELDING POSITIONPA,PB,PC,PD,PE,PF

 

TYPE OF CURRENT/GASDC+/CO2

 

Attention:

1. The rust, oil, water and other impurities of the weld area must be removed before welding.

2. The mechanical properties of all weld metal be decided by heat input, normally the small heat input will better than larger one.
