Applications Butt, fillet welding of 520N/mm2 high tensile strength steels of structure such as ships, bridges, buildings and storage tanks etc.
Characteristics (1) CSF-551 is a titania type flux cored wire and designed for all-position welding by
single pass & multi pass with CO2 gas shielding.

(2) It provides the excellent usability with stable arc, less spattering, good bead
appearance, better slag removal, and less quantity of welding fume comparable to
solid wire.

(3) It provides a good welding efficiency thank to high deposition rate particularly.
Notes on usage (1) The optimum flow of CO2 for shielding is 20~25ℓ/min.

(2) The distance between tip & base metal is to be 20~25mm.

(3) Protect the weld with a screen to prevent blowholes caused by wind where the
wind velocity is 2m/sec and more.

(4) Thick heavy plate should be welded under proper preheating & interpass
temperature.
