Mild Steel Welding Wire (HTW-49)

Conform with

GB/T

ER49-1
Description:
HTW-49 is a mild steel copper coated welding wire suitable for CO2 gas protective welding, with stable feadability, good welding seams, less spatters, and excellent welding process properties.

Application:
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 produce furnace, tubes for vessel, container building etc, suitable for semi-automatic and automatic welding under CO2 protection.
