LINCOLNWELD SUBARC WIRE L-61 - 2.0 MM - (25KG/COIL)
LINCOLNWELD® SUBARC WIRE L-61 – 2.0mm (25kg/Coil)
Premium Copper-Coated Submerged Arc Welding Wire for High-Quality Carbon Steel Fabrication
Product Overview
Lincolnweld L-61 is a premium copper-coated, low-alloy submerged arc welding (SAW) wire engineered for exceptional arc stability, consistent feedability, and superior weld metal quality. Designed for use with compatible Lincolnweld submerged arc fluxes, this 2.0mm diameter wire is supplied in a convenient 25kg coil, making it ideal for structural fabrication, shipbuilding, pressure vessel manufacturing, and heavy industrial steel construction.
Key Features
- Diameter: 2.0mm precision-drawn wire
- Coil Weight: 25kg per coil for extended, uninterrupted welding runs
- Copper Coating: Enhances electrical conductivity, prevents oxidation, and ensures smooth wire feeding through contact tips
- AWS Classification: EM12K (typical for L-61 — verify against product datasheet for exact spec)
- Low Carbon, Manganese-Silicon Alloy: Formulated for clean, low-spatter welds with excellent mechanical properties
- Tight Chemical Composition Control: Ensures consistent, predictable weld deposit quality across every batch
Benefits
? Excellent Arc Stability – Smooth, consistent arc characteristics reduce spatter and improve productivity ? High Deposition Rates – Suited for high-speed, high-current submerged arc welding applications ? Superior Weld Bead Appearance – Produces clean, uniform beads with minimal slag entrapment ? Reliable Feedability – Precision winding and copper coating minimize wire feed interruptions ? Versatile Compatibility – Works effectively with a range of neutral and active submerged arc fluxes ? Consistent Mechanical Properties – Delivers reliable tensile strength, impact toughness, and ductility in the weld deposit
Typical Applications
- Structural steel fabrication (beams, columns, girders)
- Shipbuilding and marine construction
