Pioneer 15kg High Tensile ER100S-G MIG Wire is a premium, low-alloy solid welding wire engineered specifically for joining high-strength low-alloy (HSLA) steels. While often grouped under general "mild steel" categories by suppliers, this specialized wire contains specific Ni-Cr-Mo (Nickel-Chromium-Molybdenum) additions to handle heavy-duty structural applications requiring exceptional yield strength.
Core Technical Specifications
- Classification: AWS A5.28 ER100S-G.
- Tensile Strength: Minimum of 100 ksi / 690 MPa to 770+ MPa.
- Spool Weight: 15 kg.
- Wire Type: Copper-coated, layer-wound solid wire.
- Required Shielding Gas: Argon/CO₂ mixed gas (e.g., 80/20) for optimal mechanical properties.
Primary Applications
This wire is designed for structural fabrication where standard mild steel wires (like Pioneer ER70S-6) do not provide enough load-bearing strength:
- Heavy Machinery: Earthmoving equipment, crane booms, and mining structures.
- Structural Steelwork: High-load buildings and bridges.
- Pressure Vessels: High-pressure industrial tanks and fabrication.
Key Benefits
- High Impact Toughness: Maintains weld integrity and crack resistance under immense stress and low temperatures.
- Stable Arc Performance: The precision-wound spool guarantees smooth wire feeding and minimal spatter.
- Excellent Wetting Action: Creates a clean, reliable weld bead profile.
