Description:

P 62MR is a basic-coated low hydrogen electrode producing a nominal 0.9% Ni weld metal, designed

to give excellent fracture toughness at temperatures down to -60 °C. It is an AC/DC electrode with

optimised welder-appeal, especially in the vertical up position, producing a finely rippled bead surface

and good slag detachability.

Electrode sizes 3,2x350 mm also available with a thin coating, "tc", ideally suited for root pass

welding and joints with restricted access. P 62MR conforms to NACE requirements for oil and gas

production equipment in sour service and has excellent CTOD values, making it highly suitable for

offshore applications.
