GUJIN® is a professional ER70S-6 Stainless Steel manufacturers and suppliers in China. If you interested in ER70S-6 Stainless Steel products, please contact with us. GUJIN® AWS Class ER70S-6 is a mild steel welding wire that contains higher levels of manganese and silicon than other standard grades of MIG wire to produce high quality welds when used on dirty, oily, or rusty steel. The high silicon content increases the fluidity of the weld pool, thus creating a smoother bead appearance and resulting in minimal post-weld grinding. This wire is engineered to provide porosity-free, x-ray quality welds at the highest tensile strength (as welded) of all the plain carbon steel wires. This product requires a shielding gas: CO2 and/or CO2 mix.
• General shop applications with poor fit-up or rusty, oily plates
• Steel castings or forging salvage
• Home projects
• Tanks
• Sheet metal
• Construction work
1.Keeping the package of the wire in good condition before welding.
2.To avoid welding defects the shield gas should be pure particularly no moisture in it.
3.The surfaces to be welded must be cleaned away from impurities of oil contamination, rust, moisture and so on.
4.The flowrate of the shield gas should be 20L-25L/minute and arc length in welding should be 4mm-6mm.
5.Mechanical properties, crack resistance and appearance of the weld metal are affected by heat input in welding so should pay more attention to it.
6.The welding conditions mentioned above for reference only and it is better to do a welding procedure qualification according to project before put it into formal welding.
