CO2 GAS-SHIELDED WELDING WIRE

ER50-6
ACCORD WITH:GB/T811O:ER5O-6
CORRESPONDING TO:AWS A5.18 ER7S-6DIN SG2/BS A18/JIS YGW12/EN440

DESCRIPTION:
ER50-6 is a low alloy steel gas shielded welding wire,protected with pure CO2or Ar + CO2 gas.During welding,stable arc,low spatters,excellentfabrication weldahility and low sensitivity of weld gas porosity can be obtained.It can be used for all position welding with large welding current range.

APPLICATIONS:
Suitabte for welding carbon steel and 50OMPa grade low alloy steel, such as vehicles, bridges,construction,mechanical structures etc.Also can be used in welding thin plates and pipelines with high speed.
