Lincolnweld®P223 flux is an industry
standard for spiral pipe welding on
up to X80 grade pipe, especially
where good impact properties are
required. It is also well-suited for
longitudinal seam welding on pipe,
producing a low bead profile with
very straight edges, while minimizing
undercuts. Its fast freezing slag
makes it ideal for even small diame-
ter pipe. In most cases, the slag is
self-peeling. For these same rea-
sons, P223 is an excellent choice for
many two-pass welding applications.
While designed for two-pass welding
applications, P223 is a neutral flux
which is also suitable for use in mul-
tiple pass welding with mild steel
and low alloy electrodes.
ADVANTAGE LINCOLN
• The weld deposits of neutral
P223 flux are extremely resistant
to procedural variations.
• Fast solidification of weld metal
and slag for excellent bead
appearance.
• Low dust levels make handling at
the work station clean and easy.
• Excellent weld profiles with straight
and consistent weld bead edges.
• Fast freezing slag makes P223
suitable for smaller diameter pipe.
• Slag is self-peeling on most appli-
cations.
• Designed to deliver Charpy
V-Notch impact properties that
exceed most line pipe require-
ments.
• Low diffusible hydrogen levels.
• Manufactured under a quality
system certified to ISO 9001.
TYPICAL APPLICATIONS
• Oil and gas line pipe fabrication
through X-80 grades.
• Single pass or multiple pass
welding.
• Single arc or multiple arc (up to
3 arc tandem welding).
• Straight seam or spiral seam
welding.
