OK 63.34
SMAW
Type Rutile

OK 63.34 is a stainless electrode of the 19Cr12Ni2.8Mo type, designed for welding vertical down of steels of similar composition. Vertical down welding with OK 63.34 gives beads of very good finish and a smooth transition to the joint edges. The slag volume is fairly small and is easy to manipulate and easy to remove.
