ER70S-6 0.8mm Steel Gas Shielded Arc Welding Wire
Description:
LT-ER50-6 (AWS:ER70S-6) is a mild steel welding wire that contains higher levels of Mn and Si 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.
Purpose:
1. Used for welding all kinds of 500MPa structural steel parts.
2. Used for welding all kinds of 500MPa plates and pipes
