Mild Steel Wire (ER70S-4)

Description:
ER70S-4 is a kind of mild steel copper welding wire, suitable for CO2 gas protective welding. With stable feasibility, good welding seams. Less spatter and excellent welding process properties.
Application:
Used for weld high tensile steel at 490N/mm2 grade, low current, usually used for steel 15, 20
Conform with:
GB/T: ER50-4 BS: A5.18 DIN: SG2
AWS: ER70S-4 JIS: YGW12

copper coated gas shielding welding wire is suitable for 100% co2 or Argon & mixed gas protective welding with excellent mechanical performance such as fast melting rate, high depositing efficiency, stable arc, little spatter, and beautiful seam. It is suitable for all-position welding.
The series of welding wires can be used for welding low carbon seel and low alloyed steel structure, such as ships, vehicles, bridges and buildings construction.
This series of welding wires has different kinds of packing, such as different types of plastic spools, metal spools, pail packages and straightened wire in plastic tube.

Used to welding steel for ship building (A32,E32,D32,A36,E36,D36) and mild steel products with strength at 490N/mm2 degree, such as mild alloy steel 16Mn,15Mn ect to marine boiler, pipeline, rubes for vessel, container building etc.

Applied to  steel for ship(A,B,D,E,A36,D36,E36)and at the welding of low-alloy steel's important structures at the same level of intensity.  Such as containers, vehicles, construction machinery, semi-automatic and automatic gas shielded welding.

Used for welding coal machinery, heavy machinery oil pipelines etc.
