GMAW Solid Wire Easy Arc Welding wire ISO 14341-A-G42 3C1/M21 3si1 THQ-50CG3 AWS ER70S-6 for carbon steel and low alloy steel
THQ-50CG3 AWS A5.18 ER70S-6
GMAW Solid Wire ISO 14341-A-G42 3C1/M21 3Si1
GB/T8110 ER50-6
Applications:
It can be used in the welding of carbon steel and low alloy steel in the corresponding strength grade, which can be used in engineering machinery, shipbuilding, vehicle manufacturing, petrochemical and other industries, especially in the locomotive and rolling stock manufacturing industry.
Characteristics:
Wire of THQ-50CG3 is Rm 500MPa level carbon steel wire with shield gas of CO2 or M21. The welding spatter is small, and it has beautiful shape, high cladding efficiency. It can be used for all position.
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.
