OK Tubrod 14.22
FCAW
Type Rutile

OK Tubrod 14.22 is a flux-cored tubular wire which produces weld metal of the 309 type. Whilst suitable for the 25Cr12Ni type steels the principal application is the vertical and overhead joining of dissimilar and difficult to weld steels. This will include the joining of clad steels to themselves and carbon-manganese steels. Shielding gas Ar+20% CO2.
