Descripción y aplicaciones
· Flux cored nickel base wire for gas shielded metal arc welding
· Latest generation basic slag quality guarantees optimum metallurgical quality and attractive welder appeal
· Together with enhanced productivity, FCW 4648 offers many other advantages compared to solid wires : enhanced wetting properties, increased resistance to cracking, better bead aspect and shape, use of classical M21 gas mixtures
· Maximum performances in the horizontal and downhand positions
APPLICATIONS
· FCW 4648 is suitable for welding and cladding nickel-based alloys such as alloy 600 or similar materials.
· It is also used for dissimilar welding of most nickel-based alloys to each other, to alloyed steels, or to stainless steels.
· It is a first choice consumable for heterogeneous weldments between creep-resisting ferritic steels and austenitic steels for use at high temperatures. If necessary, stress relief may be carried out.
· Repair welding on “hard-to-weld” steels
