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.
