Description of ER49-1 Mild Steel Welding Wire:
Under the protection of the copper layer, this ER49-1Mild Steel Welding Wire is with high anti-corrosion ability and excellent welding properties. Based on the combined deoxidation of Mn\Si, the welding seams have excellent mechanical properties without weld porosity and slag appearance.
Application of ER49-1, H08Mn2SiA Mild Steel Welding Wire:
Being an important welding supplies for welding process, it is widely used for CO2 gas shielded semi-automatic and automatic welding to produce marine boilers, marine pipelines, marine cargo, deck and container, which are made of ship building steel (A32, E32, D32, A36, E36, D36) and plain low carbon steel with strength at 490N/mm2 degree, as well as mild alloy steel 16Mn, 15Mn etc.
Standard-compliant:
