OK Tubrod 15.00S SAW
Type Basic F7A4-EC1
Description
OK Tubrod 15.00S is a tubular wire for submerged
arc welding in conjunction with OK Flux
10.71, when high integrity welded joints are
required in mild and medium tensile steels.
General fabrication, structural engineering and
shipbuilding are the principal areas of application.
The welding of primed plate at high speeds
is a particular benefit.
