Description:
P 51 is a basic-coated low hydrogen AC/DC electrode designed for welding mild and higher strength
steels. 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 radiographic quality.
