®
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.

welding.  
RECOMMENDED ELECTRODES  
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.

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.
