Gas-protected Solid Welding Material
GB/T 8110 G49A4UC1S6N / G49A5UM21S6N
AWS A5.18 ER70S-6
ISO 14341-A G424C14Si1
ISO 14341-A G 46 5 M21 / 42 4 C1 4Si1
Purpose
Suitable for welding various 500 MPa tensile strength grades of carbon steel and low-alloy steel. Common application areas include bridges, construction, automobile manufacturing, and mechanical structures.
Characteristics
Non-copper-coated gas-shielded solid welding wire. Excellent rust resistance, superior welding performance, stable arc, low spatter, good wire feeding, smooth weld appearance, and good mechanical properties of the deposited metal. No copper-containing fumes are generated during welding, making it an environmentally friendly welding material.
Power polarity
Direct current electrode positive (DCEP, DC+)
Protective gas
100% CO₂；15% ~ 25% CO₂ + Ar
