Lincolnweld®P223 lux is an industry
standard or spiral pipe welding on
up to X80 grade pipe, especially
where good impact properties are
required. It is also well-suited or
longitudinal seam welding on pipe,
producing a low bead pro ile with
very straight edges, while minimizing
undercuts. Its ast reezing slag
makes it ideal or even small diame-
ter pipe. In most cases, the slag is
sel -peeling. For these same rea-
sons, P223 is an excellent choice or
many two-pass welding applications.
While designed or two-pass welding
applications, P223 is a neutral lux
which is also suitable or use in mul-
tiple pass welding with mild steel
and low alloy electrodes.
ADVANTAGE LINCOLN
• The weld deposits o neutral
P223 lux are extremely resistant
to procedural variations.
• Fast solidi ication o weld metal
and slag or excellent bead
appearance.
• Low dust levels make handling at
the work station clean and easy.
• Excellent weld pro iles with straight
and consistent weld bead edges.
• Fast reezing slag makes P223
suitable or smaller diameter pipe.
• Slag is sel -peeling on most appli-
cations.
• Designed to deliver Charpy
V-Notch impact properties that
exceed most line pipe require-
ments.
• Low di usible hydrogen levels.
• Manu actured under a quality
system certi ied to ISO 9001.
TYPICAL APPLICATIONS
• Oil and gas line pipe abrication
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.

TEST RESULTS
Test results for me hani al properties, deposit or ele trode omposition and diffusible hydrogen levels were obtained from a weld produ ed and tested a ording to pres ribed
standards, and should not be assumed to be the expe ted results in a parti ular appli ation or weldment. A tual results will vary depending on many fa tors, in luding, but not limited
to, weld pro edure, plate hemistry and temperature, weldment design and fabri ation methods. Users are autioned to onfirm by qualifi ation testing, or other appropriate means,
the suitability of any welding onsumable and pro edure before use in the intended appli ation.
