Product Details
GB/T 8110: ER50-6（G49A4UC1S6N / G49A4UM21S6N）
AWS A5.18: ER70S-6
ISO 14341-A: G 42 4 M21 / C13Si1
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
