Product Description

 Introduction:HBW-49-1 is a kind of gas shielded copper-plated carbon steel welding wire, and CO2 or rich argon gas can be used for shielding. It is suitable for single pass welding or multiple pass welding and has quite high anti-blowhole property.

Application: It is applied to welding of low carbon steel (for example, Q215, Q195, etc.) and low alloy steel (for example, Q295, etc.) in industries of boilers, coal mining machinery, engineering machinery, automobile, oil and electric power.
