      It combines strength and toughness and is particularly suitable for heavily restrained sections where there can be risk of cracking due to weld stresses.

      With its excellent general operability and good positional welding characteristics P 51 is often used for pipe welding.

   

       It operates without difficulties on both primer-treated and rusty material.

   

      The electrode produces a finely rippled bead surface and smooth transition with the base material.

   

      This together with the exceptionally good slag detachability, even in root runs, gives P 51 superior radio graphic quality.
