GMAW Solid Wire AWS ER70S-6 CO2 mig welding wire

 

APPLICATIONS:

Used for welding 500MPa low alloy steel single and multi-pass welding; also for high speed thin plates, pipe line steel welding.

Suitable for manual welding, automatic welding and robot welding, such as oil machinery, heavy crane machinery, pressure vessels,

oil-chemical vessels, ship body, bridge, construction steel structure, etc.

 

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. All positions is suitable.

 

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.
