The ER70S-3 is 500MPa grade carbon steel welding wire. When paired with CO2 gas shielding, it demonstrates an excellent fluidity and crack resistance during welding process. It produces minimal spatter and forms a thin, easily removable slag. This wire is suitable for smooth and refined weld bead formation, especially the low-capacitance and high-speed welding.
Classification：
GB/T 8110 ER50-3
AWS A5.18 ER70S-3
ISO 14341-B-GS3
Application: Used for the welding of steel structure with the corresponding strength grade, as well as for the welding of low-carbon sheet workpieces with a complete surface treatment e.g. bridges, vehicle construction pipelines, vehicle manufacturing etc.
