DETAILS
Designed for in-position, high deposition welding on carbon steel. Recommended in single or multiple pass, automatic and semiautomatic welding.
Features
- High deposition rates in the flat and horizontal positions
- Smooth arc and low spatter levels
- Capable of producing weld deposits with impact properties exceeding 27 J (20 ft·lbf) at -29°C (-20°F)
- Welds on lightly rusted or primed plate
- Notes: AWS D1.8 structural steel seismic supplement test data can be found in the Lincoln Electric Certificate Center
Typical Applications
- General plate fabrication
- Structural fabrication, including those subject to seismic requirements
- Shipyards, stiffener welding on barges
- Bridges and offshore rigs
- Welding over tack welds made with stick electrode
Welding Positions
- Flat/Horizontal
