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.

Note:
1. Welding wires of other specifications can refer to the standards, and proper changes may be required according to actual needs;
2. While welding, the use performance of welding wires and the mechanical property of fused metal will be affected if it is off the standards.
