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.
