Lincoln Pipeliner® 81M 0.047 in Flux-Cored Welding Wire is a high-performance, gas-shielded flux-cored wire engineered for hot pass, fill pass, and cap pass welding on pipeline steels up to X70 grade. Purpose-built for automated and semi-automatic pipe welding systems, this wire delivers exceptional arc stability, precise arc length control, and consistent weld quality around the full circumference of the pipe. Its fast-freezing slag supports excellent puddle control, while reliable low-temperature toughness makes it a trusted solution for critical pipeline and energy infrastructure projects.
Features
- Optimized for automated pipe welding applications where consistent arc length and repeatability are critical
- Fast-freezing slag ensures excellent puddle support and uniform bead shape around the entire pipe
- Capable of producing weld deposits with impact toughness exceeding 27 J (20 ft·lbf) at -40°C (-40°F)
- Q2 Lot® certified, with online access to actual weld metal chemistry and mechanical properties by lot
- ProTech® foil bag packaging protects against moisture pickup and extends shelf life
Typical Applications
- Hot, fill, and cap pass welding on pipeline steels up to X70 grade
- Fully automated pipe welding systems
- Semi-automatic pipeline welding operations
- Pipeline projects requiring compliance with NACE standards
