®
Lincolnweld P223 flux is an industry • Excellent weld profiles with straight PRODUCT INFORMATION
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.
and consistent weld bead edges.
• Basicity Index: 1.60
• Fast freezing slag makes P223
suitable for smaller diameter pipe.
• Particle Size:
+12 Mesh 2% max.
-12/+100 Mesh 96% min.
-100 Mesh 2% max.
• Slag is self-peeling on most appli-
cations.

• Density: 1.3 g/cm
• Designed to deliver Charpy
V-Notch impact properties that
exceed most line pipe require-
ments.

ADVANTAGE LINCOLN
Single Pass or Two-Pass Welds:
®
• The weld deposits of neutral
P223 flux are extremely resistant
to procedural variations.
Lincolnweld L-61, AWS EM12K
• Single arc or multiple arc (up to
3 arc tandem welding).
®
Lincolnweld L-70, AWS EA1
(intended for applications requiring
robust Charpy impact properties).
• Straight seam or spiral seam
welding.
• Fast solidification of weld metal
and slag for excellent bead
appearance.
• Low dust levels make handling at
the work station clean and easy.

T E S T R E S U L T S
Test results for mechanical properties, deposit or electrode composition and diffusible hydrogen levels were obtained from a weld produced and tested according to prescribed
standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited
to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means,
the suitability of any welding consumable and procedure before use in the intended application.
